Transcriptional regulation is fundamental for coordinating cellular activities in response to developmental programs and environmental cues. Certain transcription factors (TFs) control the expression of hundreds of genes and are thus considered especially important — these are referred to as master…

Improving photosynthesis under abiotic stress is essential for enhancing crop productivity. Here, Jiang et al. used short-term accelerated evolution in the cyanobacterium Synechococcus elongatus to uncover genetic mutations that enhance photosynthesis under salt and light stress without compromising…

While root gravitropism (growth towards gravity) has an extended history of in-depth research, less is known about root hydrotropism (growth towards water) and about how these two potentially conflicting processes interact with each other. Since soil water distribution is often heterogeneous, plant roots…

The periderm is a protective outer tissue formed during secondary growth in many seed plants, serving as a barrier against water loss and pathogen invasion. When damaged, it can regenerate to restore its protective function. However, the molecular and cellular mechanisms underlying periderm regeneration…

Plants are renowned for their remarkable ability to regenerate tissues and organs. Two typical regeneration pathways—de novo root regeneration (DNRR) and wound-induced callus (WIC) formation—enable recovery from injury but involve entirely different cell fate outcomes. These processes also form the…

An interesting new study by Doll et al. addresses one of the most complex and important plant developmental processes, that of seed formation, with a focus on maize. Like other seeds, the maize seed (kernel) includes the next generation embryo, surrounded by various maternal tissues as well as the triploid…

In Chinese, there is an old poem suggesting that livestock bites promote crop yield in the succeeding year. In this new work, Hu et al. provide evidence to support the traditional wisdom and propose the mechanism behind it. Previous studies showed that herbivore bites on leaves induce the release of…

Review: Harnessing the power of gene regulatory networks for crop improvement The number of large molecular plant datasets seems to be growing exponentially. With this growth comes an urgent need for researchers to understand how these datasets should be analyzed and integrated to get accurate understandings…
