Differential gene expression and phenotypic variation across tissues between <i>Saccharum officinarum</i> and <i>Saccharum spontaneum</i>.

ABSTRACT: Modern sugarcane cultivars (Saccharum spp.), predominantly derived from Saccharum officinarum and Saccharum spontaneum, exhibit divergent traits in sugar content, yield, and stress tolerance. However, little is known about the spatial transcriptional regulation pattern of the differentially expressed genes (DEGs) among tissues in the two Saccharum species. This study aimed to investigate these genes according to pathways in root, stem, leaf, and flower tissues using comparative transcriptome analysis. A broad range of DEGs, ranging from 24,469 to 34,198, were identified in four tissues from Badila (S. officinarum) and Ledong2 (S. spontaneum) clones. Thirty-one DEGs involved in abscisic acid (ABA) biosynthesis were identified in the ro
