Cytokinin levels and expression profiles of cytokinin metabolic genes in late stage maize kernels

Cytokinins (CK) are key determinants of seed size and their level can impact crop yield. The biological activities and chemistry of cytokinins are well defined but less is known about their molecular mode of action during maize kernel development, especially in late stage kernels. To understand the regulation of cytokinin levels at late stage kernel development, we examined the levels of active and inactive cytokinins...
