Assays designed to detect GM plants often target the P35S and/or TNOS DNA sequences. However, because the P35S promoter is derived from CaMV, these detection assays can yield false-positives from non-GM plants infected by this naturally-occurring virus. Results: Here we report the development of an assay designed to distinguish CaMV-infected plants from GM plants in a single multiplexed quantitative PCR (qPCR) reaction. Following initial testing and optimization via PCR and singleplex-to-multiplex qPCR on both plasmid and plant DNA, TaqMan qPCR probes with different fluorescence wavelengths were designed to target actin (a positive-control plant gene), P35S, P3 (a CaMV-specific gene), and TNOS. We tested the specificity of our quadruplex qPCR assay using different DNA extracts from organic watercress and both organic and GM canola, all with and without CaMV infection, and by using commercial and industrial samples. The limit of detection (LOD) of each target was determined to be 1% for actin, 0.001% for P35S, and 0.01% for both P3 and TNOS. Conclusions: This assay was able to distinguish CaMV-infected plants from GM plants in a single multiplexed qPCR reaction for all samples tested in this study, suggesting that this protocol is broadly applicable and readily transferrable to any interested parties with a qPCR platform.}, author = {Bak, Aur{\'{e}}lie and Emerson, Joanne B.}, doi = {10.1186/s12896-019-0571-1}, file = {:C\:/Users/azzam/AppData/Local/Mendeley Ltd./Mendeley Desktop/Downloaded/Bak, Emerson - 2019 - Multiplex quantitative PCR for single-reaction genetically modified (GM) plant detection and identification of fal.pdf:pdf}, issn = {14726750}, journal = {BMC Biotechnology}, keywords = {CaMV,Cauliflower mosaic virus,Detection methods,GM plant,GMO,Multiplex qPCR}, month = {nov}, number = {1}, pages = {1--12}, pmid = {31699075}, publisher = {BioMed Central Ltd.}, title = {{Multiplex quantitative PCR for single-reaction genetically modified (GM) plant detection and identification of false-positive GM plants linked to Cauliflower mosaic virus (CaMV) infection}}, volume = {19}, year = {2019} } @misc{Baralle2017, abstract = {Alternative splicing of eukaryotic transcripts is a mechanism that enables cells to generate vast protein diversity from a limited number of genes.

Although different methods can be used for quantification of microRNAs, quantitative PCR is regarded as the reference that is used to validate other methods. Several commercial qPCR assays are available but they often come at a high price and the sequences of the primers are not disclosed. An alternative to commercial assays is to manually design primers but this work is tedious and, hence, not practical for the design of primers for a larger number of targets.Results: I have developed the software miRprimer for automatic design of primers for the method miR-specific RT-qPCR, which is one of the best performing microRNA qPCR methods available. The algorithm is based on an implementation of the previously published rules for manual design of miR-specific primers with the additional feature of evaluating the propensity of formation of secondary structures and primer dimers. Testing of the primers showed that 76 out of 79 primers (96%) worked for quantification of microRNAs by miR-specific RT-qPCR of mammalian RNA samples. This success rate corresponds to the success rate of manual primer design. Furthermore, primers designed by this method have been distributed to several labs and used successfully in published studies.Conclusions: The software miRprimer is an automatic and easy method for design of functional primers for miR-specific RT-qPCR. The application is available as stand-alone software that will work on the MS Windows platform and in a developer version written in the Ruby programming language. {\textcopyright} 2014 Busk; licensee BioMed Central Ltd.}, author = {Busk, Peter K.}, doi = {10.1186/1471-2105-15-29}, file = {:C\:/Users/azzam/AppData/Local/Mendeley Ltd./Mendeley Desktop/Downloaded/Busk - 2014 - A tool for design of primers for microRNA-specific quantitative RT-qPCR.pdf:pdf}, issn = {14712105}, journal = {BMC Bioinformatics}, keywords = {MicroRNA,Primer design,Quantitative PCR,Software}, month = {jan}, number = {1}, pmid = {24472427}, title = {{A tool for design of primers for microRNA-specific quantitative RT-qPCR}}, volume = {15}, year = {2014} } @misc{Bustin2017, abstract = {Primers are arguably the single most critical components of any PCR assay, as their properties control the exquisite specificity and sensitivity that make this method uniquely powerful.

Expression patterns in three gymnosperm taxa and heterologous expression in Arabidopsis were studied to investigate the functions of gymnosperm FT-like and TERMINAL FLOWER 1 (TFL1)-like genes. Phylogenetic reconstruction suggests that an ancient gene duplication predating the divergence of seed plants gave rise to the FT and TFL1 genes. Expression patterns indicate that gymnosperm TFL1-like genes play a role in the reproductive development process, while GymFT1 and GymFT2, the FT-like genes resulting from a duplication event in the common ancestor of gymnosperms, function in both growth rhythm and sexual development pathways. When expressed in Arabidopsis, both spruce FT-like and TFL1-like genes repressed flowering. Our study demonstrates that gymnosperms do have FT-like and TFL1-like genes.

A rice FT homolog, Heading date 3a (Hd3a), is transported from the phloem to shoot apical cells, where it interacts with 14?3?3 proteins and transcription factor OsFD1 to form a florigen activation complex (FAC) that activates a rice homolog of the floral identity gene APETALA1. Recent studies showed that florigen has roles in plant development beyond flowering; however, the exact nature of these roles is not well understood. It is not clear whether FT is transported to organs outside the shoot apex, and whether FAC formation is required for processes other than flowering. We show here that the Hd3a protein accumulates in axillary meristems to promote branching, and that FAC formation is required. Analysis of transgenic plants revealed that Hd3a promotes branching through lateral bud outgrowth. Hd3a protein produced in the phloem reached the axillary meristem in the lateral bud, and its transport was required for promotion of branching. Moreover, mutant Hd3a proteins defective in FAC formation but competent with respect to transport did not promote branching. Finally, we show that Hd3a promotes branching independently from strigolactone and FC1, a transcription factor that inhibits branching in rice. Together, these results suggest that Hd3a functions as a mobile signal for branching in rice.}, annote = {https://doi.org/10.1111/tpj.12811}, author = {Tsuji, Hiroyuki and Tachibana, Chika and Tamaki, Shojiro and Taoka, Ken-ichiro and Kyozuka, Junko and Shimamoto, Ko}, doi = {https://doi.org/10.1111/tpj.12811}, issn = {0960-7412}, journal = {The Plant Journal}, keywords = {branching,florigen,florigen activation complex,meristem action,organ development,rice (Oryza sativa L.)}, month = {apr}, number = {2}, pages = {256--266}, publisher = {John Wiley & Sons, Ltd}, title = {{Hd3a promotes lateral branching in rice}}, url = {https://doi.org/10.1111/tpj.12811}, volume = {82}, year = {2015} } @article{Whankaew2019, author = {Whankaew, Sukhuman and Ruttajorn, Kedsirin and Madsen, Claus Krogh and Asp, Torben and Xu, Li and Nakkaew, Alisa and Phongdara, Amornrat}, file = {:C\:/Users/azzam/AppData/Local/Mendeley Ltd./Mendeley Desktop/Downloaded/Whankaew et al. - 2019 - An EgHd3a-like and its alternatively spliced transcripts in the oil palm ( Elaeis guineensis ).pdf:pdf}, journal = {J.

The U1 and U2 small nuclear ribonucleoproteins (snRNPs) mark an intron and recruit the U4/U6.U5 tri-snRNP. Transfer of the 5 splice site (5 SS) from U1 to U6 snRNA triggers unwinding of U6 snRNA from U4 snRNA. U6 folds with U2 snRNA into an RNA-based active site that positions the 5 SS at two catalytic metal ions. The branch point (BP) adenosine attacks the 5 SS, producing a free 5 exon. Removal of the BP adenosine from the active site allows the 3 SS to bind, so that the 5 exon attacks the 3 SS to produce mature mRNA and an excised lariat intron.}, author = {Wilkinson, Max E and Charenton, Cl{\'{e}}ment and Nagai, Kiyoshi}, doi = {10.1146/annurev-biochem-091719}, file = {:C\:/Users/azzam/AppData/Local/Mendeley Ltd./Mendeley Desktop/Downloaded/Wilkinson, Charenton, Nagai - 2020 - Annual review of biochemistry RNA splicing by the spliceosome.pdf:pdf}, keywords = {RNA catalysis,cryo-EM,cryo-electron microscopy,crystallography,helicases,pre-mRNA splicing,spliceosome}, pages = {359--388}, title = {{Annual review of biochemistry RNA splicing by the spliceosome}}, url = {https://doi.org/10.1146/annurev-biochem-091719-}, volume = {89}, year = {2020} } @article{Wu2019, abstract = {The transition of meristems is an important developmental process for crop plants. Florigen is considered to be produced in leaves, then moves into the shoot apical meristem (SAM), triggers the transition from the vegetative to the reproductive phase.

By fused reporter gene $\beta$-glucuronidase (GUS) to 1.7 kb promoter of Heading date 3a (Hd3a), GUS signals were detected in the scutellum cells, as well as in green point of the putative transgenic calli. Quantitative RT-PCR results demonstrated that the expression level of Hd3a was increased gradually over time along with the transition from scutellum-deprived callus to shoot. As reported that ectopic expression of FT-like genes caused earlier flowering, we also found that 80% constitutive expression of Hd3a transgenic callus showed formation floral-like organ structures. However, Hd3a RNA interference (RNAi) transgenic calli did not show any obvious phenotype, although AP1 or AP1-like genes—OsMADS14, OsMADS15, and OsMADS18- expression level is decreased during callus development. Both in Hd3a and RFT1 overexpression transgenic calli, Hd3a also modulated AP1 or AP1-like genes, as well AEPALLATA (SEP)-like gene, OsMADS34 during green point formation.

Several key genes in the photoperiod pathway were differentially expressed between seedling and reproductive leaf samples in both tall and dwarf coconut. These genes included suppressor of overexpression of constans (SOC1), flowering locus T (FT), and Apetala 1 (AP1). Alternative splicing analysis of genes in the photoperiod pathway further revealed that the FT gene produces different transcripts in tall compared to dwarf coconut. The shorter alternative splice variant of FT [which included a 6 bp deletion, alternative 3′ splicing sites (A3SS)] was found to be exclusively present in dwarf coconut varieties but absent in most tall coconut varieties.

AS functions in a range of physiological processes, including plant disease resistance, but its biological roles and functional mechanisms remain poorly understood. Many plant disease resistance (R) genes undergo AS, and several R genes require alternatively spliced transcripts to produce R proteins that can specifically recognize pathogen invasion. In the finely-tuned process of R protein activation, the truncated isoforms generated by AS may participate in plant disease resistance either by suppressing the negative regulation of initiation of immunity, or by directly engaging in effector-triggered signaling. Although emerging research has shown the functional significance of AS in plant biotic stress responses, many aspects of this topic remain to be understood. Several interesting issues surrounding the AS of R genes, especially regarding its functional roles and regulation, will require innovative techniques and additional research to unravel. {\textcopyright} 2014 by the authors; licensee MDPI, Basel, Switzerland.}, author = {Yang, Shengming and Tang, Fang and Zhu, Hongyan}, doi = {10.3390/ijms150610424}, file = {:D\:/Download/ijms-15-10424.pdf:pdf}, isbn = {1042410445}, issn = {14220067}, journal = {International Journal of Molecular Sciences}, keywords = {Alternative splicing,CC-NBS-LRR,Disease resistance,Post-transcriptional regulation,RNA processing,TIR-NBS-LRR}, number = {6}, pages = {10424--10445}, pmid = {24918296}, title = {{Alternative splicing in plant immunity}}, volume = {15}, year = {2014} } @article{Yun2023, abstract = {Environmental cues regulate the transition of many plants from vegetative to flowering development.

Perilla is a nutrient-rich leaf vegetable, and the flowering mechanism remains largely elusive. We identified flowering-related genes under short-day conditions using RNA sequencing to develop an enhanced leaf production trait using the flowering mechanism in the perilla. Initially, an Hd3a-like gene was cloned from the perilla and defined as PfHd3a. Furthermore, PfHd3a is highly rhythmically expressed in mature leaves under short-day and long-day conditions. Ectopic expression of PfHd3a in Atft-1 mutant plants has been shown to complement Arabidopsis FT function, resulting in early flowering. In addition, our genetic approaches revealed that overexpression of PfHd3a in perilla caused early flowering. In contrast, the CRISPR/Cas9 generated PfHd3a-mutant perilla showed significantly late flowering, resulting in approximately 50% leaf production enhancement compared to the control. Our results suggest that PfHd3a plays a vital role in regulating flowering in the perilla and is a potential target for molecular breeding in the perilla.}, author = {Yun, Hee Rang and Chen, Chong and Kim, Jee Hye and Kim, Hae Eun and Karthik, Sivabalan and Kim, Hye Jeong and Chung, Young Soo and Baek, Hee Soon and Sung, Sibum and Kim, Hyun Uk and Heo, Jae Bok}, doi = {10.3389/fpls.2023.1133518}, file = {:C\:/Users/azzam/AppData/Local/Mendeley Ltd./Mendeley Desktop/Downloaded/Yun et al. - 2023 - Genome-edited HEADING DATE 3a knockout enhances leaf production in Perilla frutescens.pdf:pdf}, issn = {1664462X}, journal = {Frontiers in Plant Science}, keywords = {CRISPR,FT,Hd3a,flowering mechanism,perilla}, pages = {1--12}, publisher = {Frontiers Media S.A.}, title = {{Genome-edited HEADING DATE 3a knockout enhances leaf production in Perilla frutescens}}, volume = {14}, year = {2023} } @article{Zhang2022, abstract = {Background: Oil palm is the most efficient oil-producing crop in the world, and the yield of palm oil is associated with embryonic development.

Results: In this study, three cDNA libraries were prepared from embryos at S1 (early-stage), S2 (middle-stage), and S3 (late-stage). There were 16,367, 16,500, and 18,012 genes characterized at the S1, S2, and S3 stages of embryonic development, respectively. A total of 1522, 2698, and 142 genes were differentially expressed in S1 vs S2, S1 vs S3, and S2 vs S3, respectively.

In the hormone signaling pathway, genes related to auxin antagonize the output of cytokinin which regulates the development of embryo meristem. The genes related to abscisic acid negatively regulating the synthesis of gibberellin were strongly up-regulated in the mid-late stage of embryonic development. The results were reported the early synthesis and mid-late degradation of sucrose, as well as the activation of the continuous degradation pathway of temporary starch, providing the nutrients needed for differentiation of the embryonic cell.
