1-MCP treatment enhanced expression of genes controlling endosperm cell division and starch biosynthesis for improvement of grain filling in a dense-panicle rice cultivar.

Abstract excerpt

High ethylene production in dense-panicle rice cultivars impacts grain filling. 1-MCP (ethylene action inhibitor) treatment increased assimilates partitioning, cell number and size and expression of starch synthesizing enzyme genes of developing caryopses mostly in the basal spikelets of panicle at early post-anthesis stage. The gain in cell number was less compared to the increase of size. High ethylene...
