On the other hand, in our spaceflight experiment of STS-95, cucumber seedlings grown under microgravity conditions developed a peg on each side of the transition zone, suggesting that gravistimulation was required for suppressing the peg formation on the upper side of the transition zone. We considered this as negative regulation of morphogenesis (peg formation) by gravity. We have shown that exogenous auxin induces peg formation and that indole-3-acetic acid (IAA) content in the upper side of the gravistimulated transition zone is less than that in the lower side. Furthermore, inhibition of auxin efflux by TIBA treatment induces the peg formation on the upper side of the transition zone in addition to the lower side. Therefore, we proposed that gravistimulation activates auxin efflux, decreases auxin level and suppresses peg formation on the upper side of the transition zone. To examine this hypothesis, we first investigated the localization pattern of auxin efflux carrier CsPIN1 proteins in endodermal cells that are thought to sense gravity. The results suggested that its localization pattern changed to transport auxin to the lower side of the transition zone 30 min after gravistimulation. We then analyzed IAA contents in the transition zone after gravistimulation using GC-SIM-MS. Results of our quantification of IAA contents indicated that asymmetric IAA distribution was induced 30 min after gravistimulation. These results suggested that auxin efflux carrier CsPIN1 proteins in endodermal cells would induce asymmetric auxin distribution in the transition zone and play an important role in negative regulation of peg formation by gravity.","subitem_description_type":"Other"}]},"item_5_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"共催:
