| Description
| - By screening a T-DNA population of Arabidopsis mutants for alterations in inflorescence stem vasculature, we have isolated a mutant with a dramatic increase in vascular tissue development, characterized by a continuous ring of xylem/phloem. This phenotype is the consequence of premature and numerous cambial cell divisions in both the fascicular and interfascicular regions that result in the loss of the alternate vascular bundle/fiber organization typically observed in Arabidopsis stems. The mutant was therefore designated high cambial activity (hca). The hca mutation also resulted in pleiotropic effects including stunting and a delay in developmental events such as flowering and senescence. The physiological characterization of hca seedlings in vitro revealed an altered auxin and cytokinin response and, most strikingly, an enhanced sensitivity to cytokinin. These results were substantiated by comparative microarray analysis between hca and wild-type plants. The genetic analysis of hca indicated that t

- Screeningem populace T-DNA mutantů Arabisopsis pro odlišnosti ve vaskulatuře stonku byl identifikován mutant hca (high cambial activity). Důsledkem intenzivního buněčného dělení v kambiu je vznik continuální prstence floém/xylém. Fyziologická charakterizace semenáčků mutantu hca odhalila neobvyklou odezvu na auxin a cytokinin, zejména pak zvýšenou citlivost vůči cytokininu. Navrhujeme hypotézu, že hca je součástí mechanismu, který reguluje vývoj vaskulatury prostřednictvím změny citlivosti buněk kambia vůči auxinu a cytokininu. Mutant hca se jeví jako vhodný model pro studium genetické a hormonální kontroly růstu kambia a jeho diferenciace. (cs)
