Developing an Efficient System for Hybrid Rice Seed Production Using Partial Male Sterility
Plant Biotechnology Journal, EarlyView.ABSTRACT Efficient production of hybrid rice seeds requires male sterility systems to overcome the challenges of self‐pollination. In this study, we identified male gametic transfer defect (GTrD)5 and GTrD9 as essential genes for the process of male gamete transmission in rice.

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 ...

Plant Biotechnology Journal, EarlyView.ABSTRACT Oomycete pathogens secrete hundreds of RXLR effectors into plant cells to modulate host immunity by targeting diverse plant proteins. Here, we report that the Peronophythora litchii RXLR effector PlAvh133 acts as a virulence factor and targets the litchi glycolate oxidase (GLO) LcGLO1, a key enzyme in photorespiration, thereby suppressing ...

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.

TaRIP2 Positively Regulates Wheat Pollen Wall Formation Through MYB80‐Controlled Lipid Metabolism
Plant Biotechnology Journal, EarlyView.ABSTRACT Male‐sterile genes and mutants are critical for hybrid seed production in monocotyledonous crops. Lipids are essential structural components of male reproductive organs, such as the anther and pollen. Here, we show that the pollen‐preferential gene TaRIP2 is essential for wheat anther development and pollen formation. RT‐qPCR analysis revealed

Citrus psorosis virus movement protein contains an aspartic protease required for autocleavage and the formation of tubule-like structures at plasmodesmata [PDF]
, 2018 Plant virus cell-to-cell movement is an essential step in viral infections. This process is facilitated by specific virus-encoded movement proteins (MPs), which manipulate the cell wall channels between neighboring cells known as plasmodesmata (PD ...

H3K27me3‐Mediated Epigenetic Silencing of FgHMG1 Enables Fungal Host Immune Evasion
Plant Biotechnology Journal, EarlyView.ABSTRACT Histone H3 lysine 27 trimethylation (H3K27me3) is essential for fungal pathogenicity, yet its contribution to pathogen–host interactions remains incompletely understood. Here, we profiled H3K27me3 dynamics in Fusarium graminearum during infection and identified 132 H3K27me3‐marked genes (FgHMGs).

Pollen development in Mill. (Annonaceae). Implications for the evolution of aggregated pollen [PDF]
, 2009 In most flowering plants, pollen is dispersed as monads. However, aggregated pollen shedding in groups of four or more pollen grains has arisen independently several times during angiosperm evolution.

WRKY Transcription Factors: Integral Regulators of Defence Responses to Biotic Stress in Crops
Plant Biotechnology Journal, EarlyView.ABSTRACT Crops are continually challenged by biotic stresses, including fungal, bacterial and viral pathogens and insect pests, which cause substantial yield and quality losses worldwide. WRKY transcription factors constitute a plant‐specific and functionally diverse family that is central to immune regulation.
