Gravity sensing and responses in the coordination of the shoot gravitropic setpoint angle

New Phytologist, 2022
SummaryGravity is one of the fundamental environmental cues that affect plant development. Indeed, the plant architecture in the shoots and roots is modulated by gravity. Stems grow vertically upward, whereas lateral organs, such as the lateral branches in shoots, tend to grow at a specific angle according to a gravity vector known as the gravitropic ...

Gravitropism in Higher Plant Shoots [PDF]

Plant Physiology, 1989
Although the Cholodny-Went model of auxin redistribution has been used to explain the transduction phase of gravitropism for over 60 years, problems are apparent, especially with dicot stems. An alternative to an auxin gradient is a physiological gradient in which lower tissues of a horizontal stem become more sensitive than upper tissues to auxin ...

Functional mapping of gravitropism and phototropism for a desert tree, Populus euphratica

Frontiers in Bioscience-Landmark, 2021
Background: Plants have evolved the dual capacity for maximizing light assimilation through stem growth (phototropism) and maximizing water and nutrient absorption through root growth (gravitropism).

Transcriptome and metabolite analyses provide insights into zigzag-shaped stem formation in tea plants (Camellia sinensis)

BMC Plant Biology, 2020
Background Shoot orientation is important for plant architecture formation, and zigzag-shaped shoots are a special trait found in many plants. Zigzag-shaped shoots have been selected and thoroughly studied in Arabidopsis; however, the regulatory ...

Mitogen-Activated Protein Kinase Cascade MKK7-MPK6 Plays Important Roles in Plant Development and Regulates Shoot Branching by Phosphorylating PIN1 in Arabidopsis. [PDF]

PLoS Biology, 2016
Emerging evidences exhibit that mitogen-activated protein kinase (MAPK/MPK) signaling pathways are connected with many aspects of plant development. The complexity of MAPK cascades raises challenges not only to identify the MAPK module in planta but also

Gravi-Sensitivity of Mosses and Their Gravity-Dependent Ontogenetic Adaptations

Life, 2022
Gravi-morphoses affect the variability of plants and are the morphogenetic adaptation to different environmental conditions. Gravity-dependent phenotypic plasticity of gametophytes as well as gravi-sensitivity of moss protonemata in microgravity and ...

Termination of Shoot Gravitropic Responses by Auxin Feedback on PIN3 Polarity [PDF]

Current Biology, 2016
Plants adjust their growth according to gravity. Gravitropism involves gravity perception, signal transduction, and asymmetric growth response, with organ bending as a consequence [1]. Asymmetric growth results from the asymmetric distribution of the plant-specific signaling molecule auxin [2] that is generated by lateral transport, mediated in the ...

Gravitropic Analysis of Tomato Seedlings using Time Lapse Video Imaging

Bio-Protocol, 2015
Plants use gravity as a guide for growth and development. Gravitropism, a gravity-directed growth process, directs upward shoot movement for efficient photosynthesis and gaseous exchange. In addition, it also directs downward growth of roots in soil, for

SHOOT GRAVITROPISM 5 mediates the stomatal response to darkness in Arabidopsis.

Plant Biotechnol (Tokyo)
Stomatal regulation, a multifaceted mechanism enabling plants to adapt to diverse environmental conditions and optimize photosynthesis for survival and growth, is considered crucial in drought stress tolerance research. To further enhance our understanding of stomatal regulation, we investigated the novel transcription factors involved in this process.

Brassinosteroid-regulated plant growth and development and gene expression in soybean

Crop Journal, 2019
Brassinosteroids (BRs) are endogenous phytohormones that play important roles in regulating plant growth and development. In this study, we evaluated the effects of brassinolide (BL, one of the active BRs) on soybean and identified roles of the hormone ...
