Linking Superoxide Production and Scavenging in Plant Development
Plant, Cell &Environment, Volume 49, Issue 4, Page 2048-2068, April 2026.ABSTRACT Due to their strong oxidizing potential, rapid membrane permeability, and high reactivity, reactive oxygen species (ROS) play essential roles in plant development and stress responses. Superoxide (O2•‐) is a primary product of molecular oxygen reduction and a crucial source of hydrogen peroxide, representing a ROS species of substantial ...

Interaction of nitric oxide with auxin and ethylene signalling in Arabidopsis root gravitropism [PDF]
Gravitropism is required for the appropriate alignment of the plant root and shoot. According to the Cholodny-Went hypothesis, gravity induces asymmetric accumulation of auxin in the lower side of the root tissue. More recent studies on root gravitropism

Plant subtilases as key initiators of peptide ligand‐receptor signaling
The Plant Journal, Volume 126, Issue 1, April 2026.SUMMARY Peptide ligand‐receptor signaling plays a crucial role in regulating diverse biological processes in plants. Over the past three decades, numerous peptide ligands and their corresponding receptors have been identified, and our understanding of their downstream signaling pathways and biological functions has gradually advanced.

Advanced Science, Volume 13, Issue 15, 13 March 2026.Plants are promising materials for building sustainable and eco‐friendly robots due to their inherent multifunctionality, with actuation playing a crucial role. This article focuses on the physical movements of plants and, from the perspective of actuation characteristics, explores representative plant species and their behaviors, the current state of ...

New Phytologist, Volume 249, Issue 6, Page 2652-2667, March 2026.Summary With the intensification of unpredictable flooding events because of global warming, there is a need to understand how root cells perceive and respond to oxygen deprivation. The use of high‐throughput single‐nuclei RNA‐sequencing (snRNA‐Seq) allows the examination of gene expression profiles in discrete cell types.

Auxin‐mediated statolith production for root gravitropism [PDF]
, 2019 Root gravitropism is one of the most important processes allowing plant adaptation to the land environment. Auxin plays a central role in mediating root gravitropism, but how auxin contributes to gravitational perception and the subsequent response is ...

Light-dependent gravitropism and negative phototropism of inflorescence stems in a dominant Aux/IAA mutant of Arabidopsis thaliana, axr2 [PDF]
, 2014 Gravitropism and phototropism of the primary inflorescence stems were examined in a dominant Aux/IAA mutant of Arabidopsis, axr2/iaa7, which did not display either tropism in hypocotyls.

, 2019 A: In classical experiments, a plant is tilted from the vertical in order to study gravitropism. In this case, since the light is coming from the top, one side of the stem is shaded, which can induce a phototropic reaction. B: In classical experiments, a

Asymmetric cytokinin signaling opposes gravitropism in roots
, 2020 Plants depend on gravity to provide the constant landmark for downward root growth and upward shoot growth. The phytohormone auxin and its cell-to-cell transport machinery are central determinants ensuring gravitropic growth.
