Abstract Modern green revolution varieties of wheat ( Triticum aestivum L.) confer semi-dwarf and lodging-resistant plant architecture owing to the Reduced height-B1b Rht-B1b ) Rht-D1b alleles 1 . However, both are gain-of-function mutant encoding gibberellin signalling repressors that stably repress growth negatively affect nitrogen-use efficiency grain filling 2–5 Therefore, harbouring or usually produce smaller require higher nitrogen fertilizer inputs maintain their yields. Here we...
Abstract VEGETATIVE TO REPRODUCTIVE TRANSITION 2 (VRT-A2) is a subspecies-forming gene that confers the long-glume and large-grain traits of tetraploid Polish wheat (Triticum polonicum; AABB) hexaploid Xinjiang rice (T. petropavlovskyi; AABBDD). Transcriptional activation VRT-A2 due to natural sequence variation in its Intron-1 region significantly enhances grain weight but also causes some basal spikelets fail completely develop, thus decreasing number per spike yield. This yield penalty...
Dissecting genetic components in crop plants associated with heat stress (HS) sensing and adaptation will facilitate the design of modern varieties improved thermotolerance. However, molecular mechanisms underlying ON/OFF switch controlling HS responses (HSRs) wheat (Triticum aestivum) remain largely unknown. In this study, we focused on action TaHsfA1, a class A shock transcription factor, dynamically changing signals regulating HSRs. We show that TaHsfA1 protein is modified by small...
