Alternative splicing orchestrates phosphate signaling and plant growth

Guo 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.…

A spliceophilin helps Arabidopsis adapt to heat stress

Jo et al. uncover the role of a spliceosome component in removing retained introns in Arabidopsis in response to heat stress https://doi.org/10.1093/plcell/koac084  Background: Alternative splicing plays a key role in abiotic stress responses in plants, especially responses to heat stress. The spliceosome…
