Transcriptional response of abscisic acid (ABA) metabolism and transport to cold and heat stress applied at the reproductive stage of development in Arabidopsis thaliana

► Cold stress modify ABA biosynthesis and catabolism in Arabidopsis. ► Temperature stress also affects ABA transport and homeostasis. ► ABA metabolism and homeostasis differ between vegetative and reproductive organs. ► ABA metabolism and homeostasis are dynamically regulated during plant development.
