Brassinosteroid and gibberellin signaling are required for Tomato internode elongation in response to low red: far-red light

This study shows GA and BR are necessary for tomato stem elongation under low R:FR light, with IAA enhancing GA's effect.

ggPlantmap: an R package for creation of informative and quantitative ggplot maps derived from plant images.

ggPlantmap provides an R package for creating customizable ggplot maps from plant images to visualize spatial quantitative data.

Regulation and Function of a Polarly Localized Lignin Barrier in the Exodermis

This study identifies a polar lignin cap in tomato exodermis that functions similarly to the endodermal Casparian strip but is regulated by distinct transcription factors.

A suberized exodermis is required for tomato drought tolerance

This study identifies exodermal suberization as critical for drought tolerance in tomato, contrasting with Arabidopsis endodermis, and highlights the role of MYB92 and ASFT in this process.

Mechanodetection of neighbor plants elicits adaptive leaf movements through calcium dynamics

This study identifies a calcium-dependent signaling pathway in Arabidopsis that mediates touch-induced hyponasty, showing it is adaptive in plant competition.

Towards increased shading potential: a combined phenotypic and genetic analysis of rice shoot architecture

Through screening a rice diversity panel for variation in shoot architecture, we identified traits corresponding to plant shading potential and their genetic constituents.

Mechanisms of far-red light-mediated dampening of defense against Botrytis cinerea in tomato leaves

This study shows that low red:far-red light ratio increases tomato susceptibility to Botrytis cinerea by delaying pathogen detection and reducing jasmonic acid defense responses.

Far-red light enhances soluble sugar levels and Botrytis cinerea disease development in tomato leaves in a jasmonate-dependent manner

This study shows that far-red light increases soluble sugars in tomato leaves, promoting Botrytis cinerea disease through jasmonate-dependent mechanisms.

Real-time whole-plant dynamics of heavy metal transport in Arabidopsis halleri and Arabidopsis thaliana by gamma-ray imaging

The paper uses gamma-ray imaging to study real-time zinc transport dynamics in Arabidopsis species, showing differences between hyperaccumulators and non-accumulators.

Profiling of accessible chromatin regions across multiple plant species and cell types reveals common gene regulatory principles and new control modules

The paper uses ATAC-seq to profile accessible chromatin regions in multiple plant species and cell types, identifying conserved gene regulatory principles and new control modules.

Nuclear transcriptomes at high resolution using retooled INTACT

The paper retools the INTACT method for rice to enable high-resolution analysis of nuclear transcriptomes and chromatin in specific cell types.
