Two growth-related organ-specific cDNAs from Cicer arietinum epicotyls Muñoz, Francisco J. Dopico, Berta Labrador, Emilia Chickpea Epicotyls Growth Tissue-specific gene expression Two cDNAs, CanST-1 and CanST-2, encoding two different growth-related organ-specific sequences have been isolated from a cDNA library from growing epicotyls of Cicer arietinum. An intriguing property of these two clones is the presence in their coding region of a repeated sequence which is highly conserved except for the number of repeats. The corresponding genes of CanST-1 and CanST-2 encode for proteins related to elongation processes. CanST-1 and CanST-2 are up-regulated during epicotyl growth, the transcript levels of both clones decrease when the growth of epicotyls is inhibited by several treatments and their expression increases when epicotyls resume growth. Furthermore, clones CanST-1 and CanST-2 are tissue-specific and are only expressed in epicotyls, mesocotyls, roots and stem tissues whose cells undergo elongation processes. Neither clone was found to be expressed in other organs such as cotyledons, leaves, flowers, pods and immature seeds. The results of auxin (IAA) and brassinolides (BR) treatments suggest that the processes in which the proteins encoded by CanST-1 and CanST-2 are involved are not mediated by these hormones. 2024-04-08T08:27:26Z 2024-04-08T08:27:26Z 1997 2099-09-09 info:eu-repo/semantics/article 0167-4412 http://hdl.handle.net/10366/157174 10.1023/A:1005892531385 eng PB94-1395 http://creativecommons.org/licenses/by-nc-nd/4.0/ info:eu-repo/semantics/embargoedAccess Attribution-NonCommercial-NoDerivatives 4.0 Internacional
