Blue‐light‐induced PIN3 polarization for root negative phototropic response in Arabidopsis [PDF]

The Plant Journal, 2013
SummaryRoot negative phototropism is an important response in plants. Although blue light is known to mediate this response, the cellular and molecular mechanisms underlying root negative phototropism remain unclear. Here, we report that the auxin efflux carrier PIN‐FORMED (PIN) 3 is involved in asymmetric auxin distribution and root negative ...

OsPIN1a Gene Participates in Regulating Negative Phototropism of Rice Roots

Rice Science, 2014
Abstract The complete open reading frame of OsPIN1a was amplified through reverse transcriptasepolymerase chain reaction (RT-PCR) based on the sequence deposited in GenBank to explore the relationship between the auxin efflux protein OsPIN1a and the negative phototropism of rice roots.

Light-dependent gravitropism and negative phototropism of inflorescence stems in a dominant Aux/IAA mutant of Arabidopsis thaliana, axr2 [PDF]

Journal of Plant Research, 2014
Gravitropism and phototropism of the primary inflorescence stems were examined in a dominant Aux/IAA mutant of Arabidopsis, axr2/iaa7, which did not display either tropism in hypocotyls. axr2-1 stems completely lacked gravitropism in the dark but slowly regained it in light condition.

Negative Phototropism of the Creeping Shoots in Japanese Ivy, Hedera rhombea.

Journal of the Japanese Forest Society, 2011
付着根型つる植物であるキヅタ (ウコギ科) の匍匐シュートの伸長方向と光環境の関係を実験的に解析した。匍匐シュートに傾度のある光環境条件を与えた場合, 10 mm以上伸長したすべてのシュートで, キヅタは負の光屈性を示した。また, その負の光屈性は, シュートの先端が水平方向と垂直方向の光強度が均一に低下するような空間をめざして伸長するように生じていた。シュートの伸長量は光量の減少にしたがって低下したが, 20 μmol/m2/sという弱光環境においても負の光屈性は生じていた。つまり, キヅタの匍匐シュートの負の光屈性は, 単なる強光を避ける反応ではなく, 三次元空間的な光環境で暗所方向へ伸長する反応であった。この負の光屈性は, つる植物が林床の不均一な光環境下で ...

Calcium Signaling is Involved in Negative Phototropism of Rice Seminal Roots

Rice Science, 2014
Calcium ions (Ca2+) act as an intracellular second messenger and affect nearly all aspects of cellular life. They are functioned by interacting with polar auxin transport, and the negative phototropism of plant roots is caused by the transport of auxin from the irradiated side to the shaded side of the roots. To clarify the role of calcium signaling in
