AbstractThere is increasing evidence confirming that dioecious plants have evolved a
series of sex-related physiological mechanisms allowing acclimation to environmental
stresses, but few studies have attempted to thoroughly uncover the
potentialmolecular regulation underlying these responses. Recently,we found
in the dioecious plant, Populus cathayana, that males possess a greater tolerance
to enhanced UV-B radiation than do females. To continue this work
further, comparative transcriptome analyses were carried out. A total of 362
and 296 differentially expressed genes (DEGs) were detected in males and
females, respectively. Similarly, as shown in previous studies, these DEGs were
involved in a set of conserved functions and pathways related to UV-B stress,
regardless of the sex. On the other hand, sex-related responses via transcriptome
remodeling were detected, as changes in sex-related gene expression
occurred in some pathways. For example, many DEGs involved in amino
acid metabolism were mainly upregulated in males but downregulated in
females. In some pathways, DEGs were expressed predominantly or exclusively
in one sex. This may directly contribute to sex-related physiological
responses. Taken together, our results not only provide strong evidence that
males and females have adopted sex-related molecular strategies in response
to solar UV-B radiation but also suggest many new insights, in particular into
molecular regulation, via sex-biased gene expression.We conclude that these
results can further enhance the sustainable exploitation and management of
P. cathayana plants.
