Unveiling distinct storage composition and starch properties in developing indica rice grains via transcriptional profiling and enzymatic activity analysis

Wichian Sangwongchai, Kwanjeera Wanichthanarak, Ammarin In-on, Supidcha Natee et autres

expression ratio was higher in RD57, which correlated with its higher amylose content and associated differences in starch properties compared to RD6. Gene co-expression network analysis identified potential regulators of these pathways, including transcription factors bZIP10-like and bZIP44-like, and the energy signaling …
