Multi-omics integrated analysis reveals the molecular basis of coconut plant height differences. a The leaf internode phenotype of Cn. tall and Cn. dwarf. b Genome-wide association analysis of the leaf internode phenotype of coconut. The upper panel shows the Manhattan plot of SNP-GWAS for leaf internode, and the lower panel shows copy number variation between Cn. tall and Cn. dwarf in chr12 chromosome, and the right panel is haplotype analysis of leaf spacing. P values were determined using two-tailed Student’s t test. c Images of Cn. tall and Cn. dwarf at seedling stage. d Comparison of height and GA20ox expression level by qRT-PCR between Cn. tall and Cn. dwarf. e Depiction of gibberellins metabolic pathway and gene expression bias between Cn. tall and Cn. dwarf. f Difference of gibberellin content in Cn. tall and Cn. dwarf. at seedling stage. g Optical microscope photographs of cells of Cn. tall and Cn. dwarf. h Differences in leaf cell length of Cn. tall and Cn. dwarf at seedling stage
