TOP1α suppresses lateral root gravitropism in Arabidopsis
Plant Signaling and Behavior, 2022 Root gravitropism is important for anchorage and exploration of soil for water and nutrients. It affects root architecture, which is one of the elements that influence crop yield. The mechanism of primary root gravitropism has been widely studied, but it

Actin depolymerization by Latrunculin B can either suppress or promote root gravitropism, depending on the developmental stages in Arabidopsis [PDF]
Plant Signaling & BehaviorRoot gravitropism enables plants to optimize water and nutrient uptake, with actin filaments playing a key regulatory role. However, the effects of F-actin depolymerization on gravitropism have been inconsistent. Here, we show that actin depolymerization

LAZY Gene Family in Plant Gravitropism
Frontiers in Plant Science, 2021 Adapting to the omnipresent gravitational field was a fundamental basis driving the flourishing of terrestrial plants on the Earth. Plants have evolved a remarkable capability that not only allows them to live and develop within the Earth’s gravity field,

The LPA1–ITA1–BRXL4 module regulates shoot gravitropism and tiller angle in rice [PDF]
Plant CommunicationsTiller angle is a critical agronomic trait that influences rice plant architecture and yield potential. However, the molecular mechanisms underlying its regulation remain incompletely understood.

A gravitropic stimulus alters the distribution of EHB1, a negative effector of root gravitropism in Arabidopsis [PDF]
Plant Direct, 2020 In Arabidopsis gravitropism is affected by two antagonistically interacting proteins, AGD12 (ADP‐RIBOSYLATION FACTOR GTPase‐ACTIVATING PROTEIN) and EHB1 (ENHANCED BENDING 1). While AGD12 enhances gravitropic bending, EHB1 functions as a negative element.

Root Meristem Maintenance Mechanisms are Key to Plant Defense Against Nanoplastics [PDF]
Advanced ScienceThe pervasive prevalence of nanoplastics in environment poses a challenge that threatens ecosystem and agricultural production. Despite their ubiquity, the determinants of nanoplastics phytotoxicity and the mechanisms through which plants defend against ...

Frontiers in Plant Science, 2021 Starch granules in the endodermis of plant hypocotyls act as statoliths that promote hypocotyl negative gravitropism—the directional growth of hypocotyls against gravity—in the dark.

Stochastic processes in gravitropism [PDF]
Frontiers in Plant Science, 2014 In this short review we focus on the role of noise in gravitropism of plants - the reorientation of plants according to the direction of gravity. We briefly introduce the conventional picture of static gravisensing in cells specialized in sensing.

Microarray analyses and comparisons of upper or lower flanks of rice shoot base preceding gravitropic bending. [PDF]
PLoS ONE, 2013 Gravitropism is a complex process involving a series of physiological pathways. Despite ongoing research, gravitropism sensing and response mechanisms are not well understood.

Springback in Root Gravitropism [PDF]
Plant Physiology, 1989 Conditions under which a gravistimulus of Merit corn roots (Zea mays L.) is withdrawn result in a subsequent loss of gravitropic curvature, an effect which we refer to as springback.' This loss of curvature begins within 1 to 10 minutes after removal of the gravistimulus. It occurs regardless of the presence or absence of the root cap.
