Adaptive divergence in shoot gravitropism creates hybrid sterility in an Australian wildflower. [PDF]
Proc Natl Acad Sci U S A, 2021 Significance New species originate as populations become reproductively isolated from one another. Despite recent progress in uncovering the genetic basis of reproductive isolation, it remains unclear whether intrinsic reproductive barriers, such as hybrid sterility, can evolve as a by-product of local adaptation to contrasting ...

Inclination not force is sensed by plants during shoot gravitropism. [PDF]
Sci Rep, 2016 AbstractGravity perception plays a key role in how plants develop and adapt to environmental changes. However, more than a century after the pioneering work of Darwin, little is known on the sensing mechanism. Using a centrifugal device combined with growth kinematics imaging, we show that shoot gravitropic responses to steady levels of gravity in four

Cellular and physiological functions of SGR family in gravitropic response in higher plants
Journal of Advanced ResearchBackground: In plants, gravity directs bidirectional growth; it specifies upward growth of shoots and downward growth of roots. Due to gravity, roots establish robust anchorage and shoot, which enables to photosynthesize.

Interaction with gravitropism, reversibility and lateral movements of phototropically stimulated potato shoots [PDF]
Journal of Plant Research, 2016 Phototropic (PT) and gravitropic (GT) bending are the two major tropic movements that determine the spatial position of potato shoots. We studied PT bending of potato plantlets grown under long-day photoperiods in several prearranged position setups providing different interactions with the GT response.

The chemical NJ15 affects hypocotyl elongation and shoot gravitropism via cutin polymerization [PDF]
Bioscience, Biotechnology, and Biochemistry, 2018 ABSTRACT We previously found a chemical, designated as NJ15, which inhibited both auxin and brassinosteroid responses in dark-grown Arabidopsis. To study its mode of action, we performed a phenotypic screening of NJ15-low-sensitive lines among mutant pools of Arabidopsis.

Regulation of shoot gravitropism and branching angle by the GRV2-SAC1 axis in Arabidopsis. [PDF]
Plant JGravitropism is a fundamental adaptive response in plants that enables directional growth to optimize resource acquisition. In this study, we employed forward genetic screening to identify Arabidopsis mutants with defective hypocotyl gravitropism and ...
