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.

ZmWRKY29 Transcriptionally Represses ZmRBOHC to Attenuate ROS Production and Facilitates Gibberella Stalk Rot Susceptibility in Maize

Plant Biotechnology Journal, EarlyView.
ABSTRACT Gibberella stalk rot (GSR), caused by the fungal pathogen Fusarium graminearum, severely threatens maize production. However, the molecular mechanisms underlying maize resistance to GSR remain poorly understood. Here, we have identified ZmWRKY29 as a transcriptional repressor induced by F.

Nanoscale glucan polymer network causes pathogen resistance. [PDF]

, 2014
Successful defence of plants against colonisation by fungal pathogens depends on the ability to prevent initial penetration of the plant cell wall. Here we report that the pathogen-induced (1,3)-β-glucan cell wall polymer callose, which is deposited at ...

The Transcription Factor OsWRKY64 Interacts With OsART1 to Positively Regulate Al Resistance in Rice

Plant Biotechnology Journal, EarlyView.
A proposed working model illustrating the cooperative regulation of Al tolerance by OsWRKY64 and OsART1 in rice. Under Al stress conditions in acidic soil, the transcription factor OsART1 directly binds to the promoter of OsWRKY64 to activate its transcription. The synthesized OsWRKY64 protein then physically interacts with OsART1 in the nucleus.

The effect of intracellular calcium level regulators on the synthesis of pollen tube callose in Oenothera biennis L.

Acta Societatis Botanicorum Poloniae, 2014
It is shown that callose synthesis in the Oenothera biennis pollen tube is regulated by the endogenous Ca2+ level. Calcium antagonists reduced the amount of callose in the wall above the tip of the pollen tube (Verapamil - calcium channels blocker) and ...

Genomic and Transcriptomic Analyses Provide Insights Into Erysiphe necator Pathogenicity and Grapevine Response

Plant Biotechnology Journal, EarlyView.
ABSTRACT Grapevine powdery mildew, caused by the fungus Erysiphe necator, is one of the most prevalent obligate biotrophic pathogens in vineyards, posing a significant threat to grape production. Despite its impact, research on E. necator pathogenicity and grapevine responses remains limited.

ABA Is Required for Leptosphaeria maculans Resistance via ABI1- and ABI4-Dependent Signaling

Molecular Plant-Microbe Interactions, 2007
Abscisic acid (ABA) is a defense hormone with influence on callose-dependent and -independent resistance against Leptosphaeria maculans acting in the RLM1Col pathway.

Two Aquaporins Mitigate Growth‐Defence Trade‐Offs by Facilitating CO2 and H2O2 Transport in Wheat

Plant Biotechnology Journal, EarlyView.
ABSTRACT The growth‐defence trade‐offs pose a major challenge to breeding high‐yield and disease‐resistant crops. Aquaporins are membrane channels that facilitate the transport of water and other small compounds, therefore regulating the growth‐defence trade‐offs.

CRISPR/Cas‐Mediated Gene Editing in Plant Immunity and Its Potential for the Future Development of Fungal, Oomycete, and Bacterial Pathogen‐Resistant Pulse Crops

Plant, Cell &Environment, EarlyView.
ABSTRACT Pulses provide myriad health benefits and are advantageous in an environmental context as a result of their leguminous nature. However, phytopathogenic fungi, oomycetes and bacteria pose a substantial threat to pulse production, at times leading to crop failure.

Insights Into the Role of Lysine Acetylation of Non‐Histone Proteins in Plant Immunity

Plant, Cell &Environment, EarlyView.
ABSTRACT Plant immunity is regulated by numerous transcriptional and posttranslational mechanisms. Among these, lysine acetylation, which is controlled by lysine acetyltransferases (KATs) and lysine deacetylases (KDACs), has been extensively studied, particularly in the context of epigenetic regulation through histone acetylation.
