LAZY Gene Family in Plant Gravitropism [PDF]
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,

TOP1α suppresses lateral root gravitropism in Arabidopsis
Plant Signaling & 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

A minus-end directed kinesin motor directs gravitropism in Physcomitrella patens
Nature Communications, 2021 Gravitropism is the process by which plants perceive and respond to gravity. Here the authors identify a minus-end-directed kinesin required for gravity-triggered actin filament rearrangement and negative gravitropic response in the moss Physcomitrella ...

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 ...

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.

PROG1 acts upstream of LAZY1 to regulate rice tiller angle as a repressor
Crop Journal, 2023 Rice tiller angle, as a component of plant architecture, affects rice grain yield via plant density. However, the molecular mechanism underlying rice tiller angle remains elusive.
