Lateral Root versus Nodule: The Auxin-Cytokinin Interplay
WebSep 8, 2009 · In 1957, it was shown that root and shoot development in tobacco pith tissue cultures depends on the cytokinin:auxin ratio, and that organ differentiation can be regulated by changing the relative … WebMay 7, 2014 · Auxin and cytokinin regulate OsCKX4 expression in roots. A, Structure of the OsCKX4 gene promoter region. The positions of cytokinin response elements (5′-AGATT-3′) and auxin response elements (5′-TGTCTC-3′) are highlighted. Numbers below each element indicate the distance away from the ATG. WebStrikingly, the role of auxin in leaf primordia is to induce cytokinin degradation through the action of AtCKX6, and therefore to inhibit leaf growth. A major challenge in the future is to understand how HFR1/SICS1, a master negative regulator attenuating virtually all plant responses to canopy shade, relates to the TIR1 pathway. black and decker coffee maker cm4000s
