Gene Expression Divergence Between Locally Adapted Inland Annual and Coastal Perennial Ecotypes of Mimulus guttatus Across Developmental Stages

Molecular Ecology, EarlyView.
ABSTRACT The action of natural selection across heterogeneous natural landscapes drives local adaptation and the formation of plant ecotypes, the precursors to new species. Plant ecotypes typically differ significantly in morphology, physiology, and development, yet our understanding of their underlying genetic basis remains limited.

The Course of Mechanical Stress: Types, Perception, and Plant Response

Biology, 2023
Mechanical stimuli, together with the corresponding plant perception mechanisms and the finely tuned thigmomorphogenetic response, has been of scientific and practical interest since the mid-17th century.

Ecological and Mutation‐Order Speciation in Senecio

Molecular Ecology, EarlyView.
ABSTRACT Natural selection shapes how new species arise, yet the mechanisms that generate reproductive barriers remain actively debated. Although ecological divergence in contrasting environments and mutation‐order processes in similar environments are often viewed as distinct speciation mechanisms, we show they can occur simultaneously and act as part

Bundling up the Role of the Actin Cytoskeleton in Primary Root Growth

Frontiers in Plant Science, 2021
Primary root growth is required by the plant to anchor in the soil and reach out for nutrients and water, while dealing with obstacles. Efficient root elongation and bending depends upon the coordinated action of environmental sensing, signal ...

LARGE ROOT ANGLE1, encoding OsPIN2, is involved in root system architecture in rice [PDF]

, 2017
Root system architecture is very important for plant growth and crop yield. It is essential for nutrient and water uptake, anchoring, and mechanical support.

Elucidating the Genetic Basis of Columnar Upright Architecture in Populus Through CRISPR Disruption of TILLER ANGLE CONTROL1

Plant Biotechnology Journal, EarlyView.
ABSTRACT Narrow or upright branch angles in shoots and leaves lead to columnar, upright‐growing tree architectures, as observed in various tree species such as Lombardy poplar (Populus nigra var. italica). However, the genetic mechanism underlying this unique growth habit in Lombardy poplar has not yet been elucidated.

Striking the Right Chord: Signaling Enigma during Root Gravitropism

Frontiers in Plant Science, 2017
Plants being sessile can often be judged as passive acceptors of their environment. However, plants are actually even more active in responding to the factors from their surroundings. Plants do not have eyes, ears or vestibular system like animals, still

Dynamic 3D chromatin organization and epigenetic regulation of gene expression in peanut nodules

Journal of Integrative Plant Biology, Volume 67, Issue 10, Page 2624-2642, October 2025.
A 3D genomic map of peanut nodules revealed that the nodules exhibit chromatin reorganization, with 2% of regions transitioning to active states, altered topologically associating domains and enhanced cis interactions. The identification of chromatin loops that regulate nodulation genes links 3D genome dynamics to symbiotic nitrogen fixation.

A Conditional Mutation in SCD1 Reveals Linkage Between PIN Protein Trafficking, Auxin Transport, Gravitropism, and Lateral Root Initiation

Frontiers in Plant Science, 2020
Auxin is transported in plants with distinct polarity, defined by transport proteins of the PIN-formed (PIN) family. Components of the complex trafficking machinery responsible for polar PIN protein localization have been identified by genetic approaches,
