Phosphorus starvation-induced alternative splicing landscape of rice confirms the regulatory function of Pup1 QTL.

ABSTRACT: Low phosphorus (P) use efficiency of rice, in spite of sufficient P present in soil (mainly as insoluble complex), and excessive use of phosphatic fertilizers by farmers may cause several issues including higher cost of cultivation and environmental pollution. Alternative splicing of pre-mRNA is one of the strategies for transcriptome/proteome diversity that help plants to optimize acquisition and mobilization of P. Comparative analysis of rice [Pusa-44 and its Near-Isogenic Line (NIL)-23] grown hydroponically under contrasting conditions (16 ppm and 0 ppm) until vegetative stage deciphered stress-induced alternative splicing regulated through Pup1 QTL. The modulation in alternative splicing in root and shoot of rice under stress can be attributed to the regulatory function of Pup1. In add
