A Gain‐of‐Function Mutation in DELLA Selectively Alters Protein Interactions to Regulate Wheat Tiller Angle and Plant Height [PDF]
ABSTRACT Plant architecture, especially plant height and tiller angle, plays a pivotal role in determining wheat yield. In this study, we characterize a wheat mutant termed prostrate and semidwarf 1 (prose1), exhibiting both a prostrate growth habit and semidwarfism.

Arabidopsis thaliana: A Model for the Study of Root and Shoot Gravitropism [PDF]
For most plants, shoots grow upward and roots grow downward. These growth patterns illustrate the ability for plant organs to guide their growth at a specified angle from the gravity vector (gravitropism). They allow shoots to grow upward toward light, where they can photosynthesize, and roots to grow downward into the soil, where they can anchor the ...

Unifying model of shoot gravitropism reveals proprioception as a central feature of posture control in plants. [PDF]
Gravitropism, the slow reorientation of plant growth in response to gravity, is a key determinant of the form and posture of land plants. Shoot gravitropism is triggered when statocysts sense the local angle of the growing organ relative to the ...

Root Cap Cuticles Confer a Transient, Penetration-Optimised Phase During Early Seedling Establishment. [PDF]
ABSTRACT Roots emerging from seeds encounter substantial mechanical resistance during soil entry. A transient root cap cuticle (RCC) forms early in development, yet its contribution to root tip function during this mechanically challenging transition remains unclear.

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

Investigating the Role of Small RNA Pathways in Arabidopsis Shoot Gravitropism [PDF]
The plant stem grows against the gravitational force, a phenomenon called negative gravitropism. In the model dicotyledonous plant Arabidopsis thaliana, gravity is sensed by starch-filled amyloplasts, which trigger the shoot gravitropic response through ...

Characterization of a Novel Creeping Tartary Buckwheat (Fagopyrum tataricum) Mutant lazy1
Gravity is known as an important environmental factor involved in the regulation of plant architecture. To identify genes related to the gravitropism of Tartary buckwheat, a creeping line was obtained and designated as lazy1 from the mutant bank by 60Co ...

A unified model of shoot tropism in plants: photo-, gravi- and Propio-ception. [PDF]
Land plants rely mainly on gravitropism and phototropism to control their posture and spatial orientation. In natural conditions, these two major tropisms act concurrently to create a photogravitropic equilibrium in the responsive organ.

Gravitropism in Higher Plant Shoots [PDF]
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 ...

Summary: Somatic plant cells can regenerate shoots and/or roots or adventitious embryonic calluses, which may induce organ formation under certain conditions. Such regenerations occur via dedifferentiation of somatic cells, induction of organs, and their
