内容記述 | Plants determine the directional growth by responding to various environmental stimuli such as gravity, moisture, light and touch. Plant movements due to tropisms, nutation and other morphism represent those responses that interact from one another. However, plants must somehow integrate such various responses to environmental cues for exerting a proper response leading to an appropriate directional growth under specific stressful conditions. It has been shown that gravitropism strongly interacts with hydrotropism in seedling roots and suggested that the mechanisms for controlling auxin transport and distribution play essential roles in those responses. To understand molecular mechanisms of auxin dynamics to be destined by different environmental stimuli, genes of putative auxin carriers, CS-PIN1 and CS-AUX1, were isolated from cucumber and their expression patterns at both transcriptional and post-transcriptional levels were examined. The results suggested that a balance of the activity and/or localization of the two types of carriers (influx and efflux carriers) played an important role in controlling the localized concentration of auxin in gravistimulated tissues of cucumber seedlings. Because auxin dynamics also plays an essential part in hydrotropism, the expression patterns of CS-PIN1 and CS-AUX1 in hydtrostimulated roots of cucumber are now analyzed and it is compared with that in gravistimulated ones. In addition, this approach will be extended to gravitropism, hydrotropism, waving response and phototropism in Arabidopsis roots because unique mutants has been recently discovered that show specific interactions among those responses. A system of spaceflight experiment will be established for the study of auxin dynamics in microgravity, which reveals mechanisms underlying the integration of different stimulus-sensing systems by roots for controlling their directional growth. | |||||
