Dynamic transcriptomic analysis of the early response of female flowers of Populus alba × P. glandulosa to pollination.

ABSTRACT: Pollination is an important event in plant sexual reproduction, and post-pollination response is an essential process for reproduction. Populus alba × P. glandulosa is used widely in scientific research, especially in cross breeding as parents. Adult female P. alba × P. glandulosa flowers are highly compatible with pollen from male P. tomentosa, but the early post-pollination response of flowers at the molecular levels is unclear. In this study, RNA-seq was employed to comprehensively understand the response of female P. alba × P. glandulosa flowers to pollination. Enrichment analysis reveals that the 'plant hormone signal transduction' pathway is enhanced during pollen-pistil interaction. Moreover, genes related to auxin, gibberellin and ethylene biosynthesis were significantly up-regulat
