TY - JOUR ID - 896932 AU - Souček, Přemysl - Reková, Alena - Brzobohatý, Břetislav PY - 2006 TI - HORMONES AND KNOX GENES IN VEGETATIVE DEVELOPMENT OF ARABIDOPSIS THALIANA PB - MZLU v Brně CY - Brno SN - 8071579998 KW - Arabidopsis thaliana KW - homeobox genes KW - hormones N2 - Plant hormones control developmental and physiological processes by regulation of the specific genes expression. KNOX genes (knotted1-like homeobox genes) encode transcription factors containing homeodomain. Hormonal regulation of gene expression in KNOX gene family was investigated. Ethylene and gibberellin treatments did not result in altered BP (BREVIPEDICELLUS) expression. However, BP expression was strongly down-regulated by abscisic acid, and increased following auxin treatment in correlation with the initiation of lateral root meristems strongly expressing BP. Short-term endogenous cytokinin overproduction repressed STM (SHOOTMERISTEMLESS) specifically in hypocotyls and decrease in light intensity enhanced this repression dramatically. Long-term CK action caused an increase in all other KNOXI transcripts in hypocotyls that apparently correlated with the radial expansion of vascular tissues which are the main domains of KNOX I gene expression.
