LAP3, a novel plant protein required for pollen development, is essential for proper exine formation [PDF]

, 2009
We isolated lap3-1 and lap3-2 mutants in ascreen for pollen that displays abnormal stigma binding.Unlike wild-type pollen, lap3-1 and lap3-2 pollen exine isthinner, weaker, and is missing some connections betweentheir roof-like tectum structures.

Imaging plant germline differentiation within Arabidopsis flowers by light sheet microscopy [PDF]

, 2020
In higher plants, germline differentiation occurs during a relatively short period within developing flowers. Understanding of the mechanisms that govern germline differentiation lags behind other plant developmental processes.

Chromatin Topology Reconfiguration Orchestrates Thermotolerant Male Fertility via GhAL5 in Cotton

Advanced Science, EarlyView.
This study investigates cotton’s high‐temperature (HT) response using multi‑omics. Dynamic 3D genome changes drive expression bias affecting male fertility. The tolerant line shows controlled chromatin dynamics, while the sensitive line exhibits overactivation.

Ecosystem‐Centered Robot Design: Toward Ecoresorbable Sustainability Robots (ESRs)

Advanced Science, EarlyView.
Robots exploring natural ecosystems can support monitoring and conservation, but must adopt ecosystem‐centered design to avoid pollution, waste, and damage. This review proposes guidelines for co‐designing ecoresorbable sustainability robots (ESRs), uniting materials, robotics, and ecological contexts in a single framework.

PtABI3 represses the age biomarker gene PtDAL1 during male cone development in conifer

Forestry Research
The age biomarker gene PtDAL1 in conifers undergoes expression resetting during pollen maturation, but its regulatory mechanisms remain unclear. This study identifies PtABI3, a B3 transcription factor (TF) in Pinus tabuliformis, as a key repressor of ...

MDP25‐VDAC3 Complex Orchestrates Actin Remodeling and Mitochondrial Dynamics to Modulate Innate Immunity in Arabidopsis

Advanced Science, EarlyView.
This study reveals that actin remodeling regulates mitochondrial elongation as a defense strategy in plants. Flagellin perception induces fusion‐dependent elongation, supported by cortical actin bundles, to repair damage and boost ATP and ROS production.

Untargeted metabolomic analysis of tomato pollen development and heat stress response

Plant Reproduction, 2017
Pollen development metabolomics. Developing pollen is among the plant structures most sensitive to high temperatures, and a decrease in pollen viability is often associated with an alteration of metabolite content. Most of the metabolic studies of pollen

Multimodal Optical Imaging and Modulation with Simultaneous Electrophysiology Through Smart Dura in Non‐Human Primates

Advanced Science, EarlyView.
This study demonstrates multimodal integration in non‐human primates, combining large‐scale, high‐density electrophysiology using Smart Dura with optical techniques such as multiphoton imaging (MPI), photothrombotic lesioning, optical coherence tomography angiography (OCTA), wide‐field intrinsic signal optical imaging (ISOI), and optogenetics.

Enhancement of developmental defects in the boron‐deficient maize mutant tassel‐less1 by reduced auxin levels

Journal of Plant Nutrition and Soil Science, EarlyView., 2023
Abstract Background Plant responses to deficiencies of the micronutrient boron are diverse and go beyond the well‐characterized function of boron in cell wall crosslinking. To explain these phenotypic discrepancies, hypotheses about interactions of boron with various phytohormones have been proposed, particularly auxin.

Candidate Reference Genes Selection and Application for RT-qPCR Analysis in Kenaf with Cytoplasmic Male Sterility Background

Frontiers in Plant Science, 2017
Cytoplasmic male sterility (CMS) is a maternally inherited trait that results in the production of dysfunctional pollen. Based on reliable reference gene-normalized real-time quantitative PCR (RT-qPCR) data, examining gene expression profile can provide ...
