Plants avoid mutational damage buildup by leveraging randomness in a process called segregation. Unlike passing on the same mutation to all offspring, plants distribute inherited damage randomly, with some offspring inheriting more mutations than others. This segregation process, faster in…

New research could help breed plants that are more productive as days grow shorter. The research found that when days are shorter, plants have less time to photosynthesize, so they need to be more efficient with the sunlight they do…

A genetic breakthrough unveils the high-iron mutations in peas, presenting opportunities for fortified vegetables and cereals. This discovery, based on a newly mapped pea-genome, could guide gene-editing strategies to enhance iron content in various crops, addressing global anaemia concerns, especially…

Plants employ plasmodesmata for cell communication, but protein targeting to these structures is poorly understood. Studying PDLP5 and related proteins, researchers discovered unconventional targeting signals in their extracellular regions, crucial for regulating viral movement. New study aims to uncover the…
