From: The Inferior Grain Filling Initiation Promotes the Source Strength of Rice Leaves
Activities of key enzymes and relative gene expression on carbon metabolism in the top three leaves at early grain filling stage of 2020. A The activity of SPS, AGPase, and α-Amylase in the top three leaves at 8 DPA; B the level of gene expression relating carbon metabolism in the top three leaves at 8 DPA; C working model of carbon metabolism in source leaves of rice during daytime; C, CJ03; W, W1844; T0, control group with no removing-spikelets; T1, removing top 2/3 of the spikelets in panicle; Four types of genes expression level were measured: relating sucrose synthesis (OsSPS1), relating starch synthesis (OsSUS3, OsSUS4, and OsAGPL1), and relating starch degradation (OsAmy3); The data are the means of three biological replications ± SD, consisting of 3 technical replications in each biological replication
