A new report shows that the HY5 transcription factor moves from shoots to roots in plants, mediating light regulation of root growth and nitrate uptake. This finding offers not only a mechanistic insight into shoot-root communication, but also scope for increasing crop yields.
一份新报告显示,HY5 转录因子在植物中从茎部转移到根部,介导光对根生长和硝酸盐吸收的调控。这一发现不仅为茎-根通讯提供了机制上的深入了解,也为提高作物产量提供了可能。
