Fig. 4From: Integrating transcriptomics and metabolomics to characterise the response of Astragalus membranaceus Bge. var. mongolicus (Bge.) to progressive drought stressThe hierarchical analyses of co-expression transcripts at different stages of drought stress. Green indicates the down-regulated and red indicates the up-regulated expression of genes (Control: 0 day, Water-stress-1: water stress for 6 days, Water-stress-2: water stress for 10 days, Water-stress-3: water stress for 14 days)Back to article page
