The PIN2 ortholog in barley modifies root gravitropism and architecture. [PDF]

open access: yesPlant Genome
Abstract Roots provide the critical interface where plants acquire nutrients and water, but our limited understanding of the genetic controls modulating root system architecture (RSA) in crop species constrains opportunities to develop future cultivars with improved root systems.

Water as a Compass: Hydrostimulation-Triggered Aerial Root Growth in Phalaenopsis aphrodite. [PDF]

open access: yesPhysiol Plant
ABSTRACT Epiphytic orchids have evolved specialized adaptive strategies, such as aerial roots with water‐absorbing velamen tissues, to cope with water‐scarce and nutrient‐deficient habitats. Our previous study revealed that the aerial roots of the epiphytic orchid Phalaenopsis aphrodite lack a gravitropic response, raising the possibility that ...

Dynamic GOLVEN-ROOT GROWTH FACTOR 1 INSENSITIVE signaling in the root cap mediates root gravitropism.

open access: yesPlant Physiology, 2023
Throughout exploration of the soil, roots interact with their environment and adapt to different conditions. Directional root growth is guided by asymmetric molecular patterns but how these become established or are dynamically regulated is poorly ...

EARLY STARVATION 1 Is a Functionally Conserved Protein Promoting Gravitropic Responses in Plants by Forming Starch Granules

open access: yesFrontiers 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.

PIN-FORMED is required for shoot phototropism/gravitropism and facilitates meristem formation in Marchantia polymorpha.

open access: yesNew Phytologist, 2023
PIN-FORMED auxin efflux transporters, a subclass of which is plasma-membrane-localized, mediate a variety of land plant developmental processes via their polar localization and subsequent directional auxin transport. We provide the first characterization

A quantitative model for spatio-temporal dynamics of root gravitropism

open access: yesbioRxiv, 2023
Plant organs adapt their morphology according to environmental signals through growth-driven processes called tropisms. While much effort has been directed in the development of mathematical models describing the tropic dynamics of aerial organs, these ...

Microarray analyses and comparisons of upper or lower flanks of rice shoot base preceding gravitropic bending. [PDF]

open access: yesPLoS 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.

Mutation of OsPIN1b by CRISPR/Cas9 Reveals a Role for Auxin Transport in Modulating Rice Architecture and Root Gravitropism

open access: yesInternational Journal of Molecular Sciences, 2022
The distribution and content of auxin within plant tissues affect a variety of important growth and developmental processes. Polar auxin transport (PAT), mainly mediated by auxin influx and efflux transporters, plays a vital role in determining auxin ...

Gravitropic Gene Expression Divergence Associated With Adaptation to Contrasting Environments in an Australian Wildflower. [PDF]

open access: yesMol Ecol
ABSTRACT Plants adapt to their local environment through complex interactions between genes, gene networks and hormones. Although the impact of gene expression on trait regulation and evolution has been recognised for many decades, its role in the evolution of adaptation is still a subject of intense exploration.

BRXL4‐LAZY1 interaction at the plasma membrane controls Arabidopsis branch angle and gravitropism

open access: yesThe Plant Journal, 2022
SUMMARY Gravitropism guides growth to shape plant architecture above and below ground. Mutations in LAZY1 impair stem gravitropism and cause less upright inflorescence branches (wider angles).
