Members of the Arabidopsis FORKED1-LIKE gene family act to localize PIN1 in developing veins (J Exp Bot.)
Plant Science Research WeeklyVascular system is one of the adaptive features for terrestrial plants. Polar localization of PIN1 is essential for creating directional auxin flow, resulting in vein pattern formation. Mariyamma et al. propose that FORKED1 (FKD1) and its homologues control the PIN1 polar localization. The team identified…
Arabidopsis DEFECTIVE KERNEL1 regulates cell wall composition and axial growth in the inflorescence stem
Blog, Plant Science Research Weekly, Research, Research BlogPlants can reach impressive heights, thanks to the mechanical stability provided by the cell walls. The required strength is ensured by coordination of cell wall deposition and cell expansion. Plant-specific calpain (DEK1) regulates axial stem growth, as lines overexpressing the calpain domain develop…
