Genome-wide analysis of late-embryogenesis abundant (LEA) proteins in coffee. LEA genes were classified according to hierarchical clustering analysis of transcript abundance in C. canephora roots, stamens, pistils, leaves, and perisperm at 180 d after flowering (DAF) and in endosperm at 260 DAF. Expression levels in C. canephora tissues and in C. arabica zygotic embryos and endosperm at 150 and 200 DAF are indicated by the blue dots, the size and intensity of which represent the number of reads per kilobase and million reads (rpkm; see key). LEA peptides detected in the heat-stable proteome of mature seeds are labelled with an orange star. LEA genes differentially expressed during seed development as shown by microarray data analysis are labelled with a diamond (closed diamonds indicate LEA genes differentially expressed during the stage 5–6 transition).
