Spatiotemporal expression of DS1. a Expression pattern of DS1 based on the Rice eFP Browser. b Quantitative RT-PCR analysis of DS1 expression in various rice tissues. Roots and leaves were harvested from plants at the early booting stage. Internodes and stems were collected from 5-week-old seedlings. Panicles were collected when they had reached 2 cm length. Seeds were collected at grain filling. c Effect of 24-epiBL on DS1 expression. 5-day-old seedlings of the wild type (WT) were harvested after treatment with 1 μM 24-epiBL. CK represents the mock-treated control
