Molecular mechanism analysis of natural leaf abscission in sugarcane based on multi-omics and mining of key genes in ABA pathway
Poor leaf abscission in sugarcane significantly increases harvesting costs and constrains mechanized efficiency, yet its molecular basis remains poorly understood. Here, we performed an integrated hormone-targeted metabolomics and transcriptomics analysis in three sugarcane cultivars (GT47, LZ02-169, and ROC22) with...
