Figure. S4. Heatmap of the expression levels of HRGP genes in reproductive tissues. A. The expression levels of HRGP genes in pollen. MP, HP, PT and SPT correspond to four different developmental stages: matured pollen, hydrated pollen, growing pollen tubes after three hours of hydration and stopped growing pollen tubes, respectively. B. The expression levels of HRGP genes in the pistils of ‘Jinzhui’ pollinated with self- and non-self-pollen; JY24, JJ24, JY48, JJ48, JY72 and JJ72 refer to pollinated pistils corresponding to time after pollination. The colour scale represents log2 transformed reads per kilobase per million (RPKM) values. Light green indicates low expression and red indicates high expression. (PDF 313 kb)
