Jasmonate action and crosstalk in flower development and fertility.

Flower development and fertility are coordinately regulated by endogenous developmental signals, including the phytohormones jasmonates (JAs), auxin, and gibberellin, and environmental cues. JAs regulate stamen development and fertility at basal conditions, affect root growth and trichome formation under stress conditions, and control defense responses against insect herbivores and pathogens. Since 1990s, an increasing number of studies have revealed the essential roles of JA biosynthesis, signaling, and crosstalk in regulation of flower development and fertility. Here, we summarize and present an updated overview of JA pathway and crosstalk in modulating flower/sexual organ development and fertility in Arabidopsis, tomato, rice, maize, and sorghum.
