Fig. 6: Phenotypic and transcriptomic characterization of tea plant resistance to Colletotrichum gloeosporioides infection.

a Lesion phenotypes of CT, CSA, and CSS accessions after C. gloeosporioides (Cg) infection. CT2, CT4, CT5, and CT7 belong to the CT group; YK11, YK47, YK50, and YC1 belong to the CSA group; ZYQ, FDDB, JX, and RZWL belong to the CSS group. CK represents mock infection with water. b Statistical analysis of lesion areas in 18 tea accessions post-infection (Supplementary Fig. 13). Box plots show the median (center line), first and third quartiles (box bounds), and whiskers extending to 1.5× the interquartile range. Sample sizes: CT1 (n = 21), CT2 (n = 27), CT3 (n = 27), CT4 (n = 32), CT5 (n = 27), CT6 (n = 15), CT7 (n = 33), CT8 (n = 26), YK47 (n = 28), YK11 (n = 30), YK50 (n = 30), YK10 (n = 30), YC1 (n = 18), BHZ (n = 29), ZYQ (n = 33), FDDB (n = 26), RZWL (n = 30), and JX (n = 27). c Comparative lesion area analysis among CT (n = 8), CSA (n = 5), and CSS (n = 5). Data are presented as mean ± SD. Different lowercase letters indicate significant differences at P < 0.05 (one-way ANOVA with Waller–Duncan multiple-range test for post-hoc pairwise comparisons). Groups sharing the same letter are not significantly different. d Statistical classification of R genes across the CT, CSA, and CSS genomes, identifying seven RGA types. e Collinearity analysis showing the presence of the ZC102AChr03G019210.1 gene in cultivated tea genomes (CSS, CSA) and its absence in wild tea genomes (CT). f Venn analysis of two gene sets: DEGs of Cg (differentially expressed genes identified from transcriptome analysis of seven accessions post-Cg infection: CT1, CT4, CT7, YK11, YK47, FDDB, and ZYQ) and CT-SV genes (genes in the CT genome with SVs in their promoter regions). g KEGG pathway enrichment analysis of the 36 intersecting genes identified in (f), statistical significance (−log10(p-value)) calculated using hypergeometric test (one-tailed).
