Auxin regulated cell differentiation

Together with the even distribution of lAA (Table 1), these data lead to the conclusion that the phototropic movement of the radish hypocotyl is caused by a light-induced lateral distribution of three substances that differentially inhibit the auxin-regulated cell elongation at the two flanks.

Herein we describe progress to date towards elucidating the roles of these two classes of hormones and their interaction with light in regulating the development of P. patens. Special emphasis is given to the use of auxin and/or cytokinin sensitivity mutants, and future prospects for understanding the molecular basis of cell differentiation, morphogenesis and hormone action in this model system are discussed.

The cytokinins (previously phytokinins) principally stimulate cell division and, together with auxins and gibberellins regulate the developmental and differentiation processes of fruit formation and ripening, bud formation, etc.. ... 

Auxins control many aspects of plant growth and development. Physiological processes such as cell elongation, cell division, differentiation, tropisms, rooting, fruit development and abscission are influenced by auxin [ 16,50,62]. However, the mechanism by which this hormone regulates diverse physiological processes is...
