This e-book presents a accomplished assessment of all elements of the molecular and phone biology of abscisic acid (ABA) metabolism, delivery and sign transduction, masking our present figuring out of ABA in addition to learn developments. the rural value of ABA metabolism, shipping and sign transduction is additionally mentioned. The phytohormone ABA regulates many points of plant improvement and performs a vital position in plant variation to environmental stresses. over the last few many years, enormous advances were made within the examine of ABA metabolism, shipping and sign transduction, drastically deepening our figuring out of the underlying mechanisms of ABA functionality on the molecular, telephone and whole-plant point and assisting us increase plants’ environmental tolerance. This e-book offers a useful source for researchers and complex scholars drawn to plant biology and agriculture.

These facts suggested that epoxycarotenoids could be the precursors of ABA in higher plants. On the other hand, terpenoids such as carotenoids, plastoquinone, sterol, and phytol are synthesized from IPP produced in the MEP pathway in plastids (Lichtenthaler 1999). The Arabidopsis chloroplasts altered 1 (cla1) mutant has a defect in the synthesis of 1-deoxy-d-xylulose-5-phosphate in the MEP pathway and presents carotenoid deficiency resulting in decreased levels of ABA (Estevez et al. 2001). These facts support that C15 ABA is synthesized via C40 epoxycarotenoids that are composed of IPP from the MEP pathway in plants.
