Auxin, Cytokinin and Ab sei sic Acid

摘要: Abstract Auxin, cytokinin, and abscisic acid (ABA) are important plant hormones that regulate many growth developmental processes. In recent years, a number of genes involved in the metabolic signaling pathways for auxin, cytokinin ABA have been cloned characterized. With organ-and tissue-specific or conditionally active gene promoters, it has become possible to manipulate concentrations planta create commercially desirable traits. Seedless fruit production extension shelf life green produce ornamental plants two successful examples manipulating these planta. this review, we will focus our discussion on effects over-or under-expression biosynthetic catabolic with an emphasis their potential applications crops.
