MYB Transcription Factor Family in Pearl Millet: Genome-Wide Identification, Evolutionary Progression and Expression Analysis under Abiotic Stress and Phytohormone Treatments.

Transcription factors (TFs) are the regulatory proteins that act as molecular switches in controlling stress-responsive gene expression. Among them, the MYB transcription factor family is one of the largest TF family in plants, playing a significant role in plant growth, development, phytohormone signaling and stress-responsive processes. Pearl millet ( L.

Synthetic Promoters from Strawberry Vein Banding Virus (SVBV) and Dahlia Mosaic Virus (DaMV).

We have constructed two intra-molecularly shuffled promoters, namely S100 and D100. The S100 recombinant promoter (621 bp) was generated by ligation of 250 bp long upstream activation sequence (UAS) of Strawberry vein banding virus (SV10UAS; - 352 to - 102 relative to TSS) with its 371 bp long TATA containing core promoter domain (SV10CP; - 352 to + 19). Likewise, 726 bp long D100 promoter was constructed by fusion of 170 bp long UAS of Dahlia mosaic virus (DaMV14UAS; - 203 to - 33) with its 556 bp long core promoter domain (DaMV4CP; - 474 to + 82).

Synthetic promoters from blueberry red ringspot virus (BRRV).

We analyzed the synthetic full-length transcript promoter of Blueberry red ringspot virus (BRRV) and developed two chimeric promoters (MBR3 and FBR3). Transcriptional activities of these chimeric promoters were found equivalent to that of the CaMV35S promoter. Chimeric promoters driven plant-derived PaDef protein showed high antimicrobial activities against several pathogens.
