From: OsSGL, a novel pleiotropic stress-related gene enhances grain length and yield in rice
Hierarchical cluster analysis of the significantly impacted genes in 93-11-OE at the floral development stage under normal conditions.
Heatmaps represent mean expression values (n = 3) for OsSGL-overexpressing line C3–1 and wild-type 93-11. Genes impacted by OsSGL overexpression as revealed by microarray analysis include genes involved in (A) abiotic stress response (73 genes), (B) cytokinin receptor/signaling (34 genes), (C) cell cycle (76 genes), (D) plant hormones (GA, BR, IAA, ethylene and ABA) response/biosynthesis/signaling (119 genes), (E) kinase and transcription factors (64 genes) and (F) proteins functioning in metabolic processes (49 genes). 1 P, young panicle of 3 to 6 cm in length before heading; 2 P, panicle over 15 cm 3 days before heading; 3 P, panicle 10 days after heading. The signal values are log2-transformed and subjected to complete linkage hierarchical clustering with HemI program68. The colored bars at the bottom represent the z-score values transformed from log2-based expression values with blue color indicating low level (down-regulation), green indicating medium level, and red signifying high level (up-regulation).
