Quantification Of Auxin-Cytokinin Response During Primary Root And Lateral Root Development In Common Bean, Gurdeep Singh Jan 2025

Quantification Of Auxin-Cytokinin Response During Primary Root And Lateral Root Development In Common Bean, Gurdeep Singh

Electronic Theses and Dissertations

Roots support water and nutrient uptake, anchorage, and soil interactions through continuous growth at the primary root tip (PRT). In common bean (Phaseolus vulgaris), new cells are produced in an open root apical meristem and subsequently elongate in the elongation zone, and together these processes drive root tip progression through the soil. Lateral roots (LRs) arise in the differentiation zone, where pairs of pericycle founder cells dedifferentiate, divide asymmetrically, and form lateral root primordia (LRP) that pass through defined developmental stages before emergence. Auxin and cytokinin (CK) are central regulators of both primary root growth and LR development, yet their …
