Structural insights into PHO1: A key regulator of phosphate translocation in plants
Plant Science Research WeeklyPhosphorus (P) is an essential macronutrient required for plant growth, development, and reproduction. It is primarily absorbed by plant roots in the form of orthophosphate (Pi). The root-to-shoot translocation of Pi depends on a crucial xylem-loading process mediated by PHOSPHATE 1 (PHO1), a Pi efflux…
Alternative splicing orchestrates phosphate signaling and plant growth
The Plant Cell: In a NutshellGuo et al. demonstrate that alternative splicing of REGULATOR OF LEAF INCLINATION 1 modulates phosphate signaling and plant growth in the face of phosphate deficiency.
By Meina Guo, Wenyuan Ruan, and Keke Yi
Background: Phosphate (Pi) limitation represents a primary constraint on crop production.…
