Hooked hairs: A new cell type aiding seedling survival in common bean
Plant Science Research WeeklyRoots play a critical role in determining seedling resilience mechanisms to abiotic stress conditions. Despite advancements in the characterization of root systems at phenotypic and cellular levels, the diversity of belowground epidermal microstructures remains poorly understood, particularly prior…
Bidirectional root-shoot signaling via CCR1 regulates cluster root and nodule development in legumes
Plant Science Research WeeklyLegume plants are renowned for their ability to form symbiotic relationships with nitrogen-fixing bacteria (rhizobia) in specialized root tissues called nodules. This symbiosis enables the conversion of atmospheric nitrogen into ammonia, a form of nitrogen that plants can readily use for growth. This…
N-mediated heading date-1 (Nhd1) regulates nitrogen uptake efficiency and root growth in rice (Plant Physiol)
Plant Science Research WeeklyIn rice, the transcription factor N-mediated heading date-1 (Nhd1) activates the expression of Heading date 3a (Hd3a), a floral regulator gene and regulate flowering. Li et al. report the role of Nhd1 in nitrogen (N) use efficiency and N-dependent root growth in rice. nhd1 mutants were impaired in root…
