Expression of LRR-RLK genes in different tissues, leaf gradients, and day-night rhythms in Saccharum. a The expression heatmap of LRR-RLK genes in different tissues of two Saccharum species. b The expression heatmap of LRR-RLK genes in leaf gradients of two Saccharum species. c The expression pattern of LRR-RLK genes in circadian rhythms in two Saccharum species. d The Clustering of C-means expression trend of LRR-RLK gene family in circadian rhythms from Saccharum officinarum, which has four types in total. e The Clustering of C-means expression trend of LRR-RLK gene family in circadian rhythms from Saccharum spontaneum, which has four types in total. f RT-qPCR verification the expression pattern of SoLRR-RLK genes in gradient developmental leaves.
