Iron is essential for plant growth and development, but its availability in soil is often limited. Besides absorbing iron from the soil, plants can also reuse iron stored in their cell walls, although the mechanisms regulating this process remain unclear. In a recent study, Chunyan Tu and colleagues investigated how the transcription factor ANAC017 regulates […]
As leaves age, they gradually lose chlorophyll and begin to turn yellow, a process known as leaf senescence. Although this process helps plants recycle nutrients, delaying it can be beneficial for crops where leaf quality matters. Luden and colleagues investigated how the transcription factor AHL15 influences leaf senescence in Arabidopsis thaliana. The researchers found that plants […]
Green leaves are essential for photosynthesis and crop productivity, but the genes that maintain normal leaf development can also influence other aspects of plant growth. In this study, Wang et al. investigated a rice mutant called yellow-green leaf and reduced tillering (ygrt), which develops yellow-green leaves and produces fewer tillers throughout its life cycle. The mutant contained […]
When plants first moved onto land, they encountered challenges that aquatic ancestors never faced, including heat, dehydration, and rapidly changing environmental conditions. This review by Wang et al., explores how cytokinin signaling, a pathway best known for regulating plant growth and development, may have helped plants adapt to these new stresses over hundreds of millions […]
Potato productivity is highly vulnerable to drought and salinity, yet the signaling mechanisms underlying stress adaptation remain incompletely understood. A recent study by Zhu et al. used a genome-wide analysis of the mitogen-activated protein kinase kinase kinase (MAPKKK) family in potato and identified 85 StMAPKKK genes distributed across the genome. Expression profiling revealed that several […]
