Non-separated microspores 1 controls male meiotic callose deposition at the cell plate in rice

Crop Journal
In flowering plants, callose (β-1,3-glucan) plays a vital role in pollen development, especially in the separation and development of microspores. However, the molecular mechanism of callose deposition during rice pollen development remains unclear.

Cell‐Specific Expression and Cellular Compartmental Regulation in Camptothecin Biosynthesis

Plant Biotechnology Journal, EarlyView.
ABSTRACT Plant secondary metabolites such as monoterpenoid indole alkaloids (MIAs) show tightly regulated biosynthesis and accumulation in specific organelles of distinct cell types. However, the cell‐specific expression patterns of anticancer MIA camptothecin biosynthetic genes in Ophiorrhiza pumila and the regulatory mechanisms of camptothecin ...

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.

Novel Amino Acid Changes Increase Phosphoenolpyruvate Carboxylase Output in planta

Plant, Cell &Environment, EarlyView.
ABSTRACT Characterization of previously reported Arabidopsis mutants with increased aluminum (Al) resistance (alr) resulting from greater release of Al‐chelating malate identified three unique amino acid substitutions that each impacts PHOSPHOENOLPYRUVATE CARBOXYLASE 1, a key anaplerotic carbon fixation enzyme.

Plasmodesmata Function and Callose Deposition in Plant Disease Defense

Plants
Callose, found in the cell walls of higher plants such as β-1,3-glucan with β-1,6 branches, is pivotal for both plant development and responses to biotic and abiotic stressors.

Tripartite Interaction Between Penicillium pinophilum‐Host Plants and CMV‐Y: A Model for Endophyte‐Mediated Viral Biocontrol

Plant, Cell &Environment, EarlyView.
ABSTRACT Plant‐fungus‐virus tripartite interactions represent complex ecological systems in which mutualistic endophytes can influence host physiology, yet the molecular basis of endophyte‐mediated defence remains poorly understood. Here, we demonstrate that the endophytic fungus Penicillium pinophilum EU0013 suppresses the yellow strain of cucumber ...

New insight into silica deposition in horsetail (Equisetum arvense)

BMC Plant Biology, 2011
Background The horsetails (Equisetum sp) are known biosilicifiers though the mechanism underlying silica deposition in these plants remains largely unknown.

Classical imaging in callosal agenesis

Journal of Pediatric Neurosciences, 2018
Corpus callosal agenesis results in certain characteristic radiological appearances on magnetic resonance imaging. These classical named signs are revisited in this article.

An Arabidopsis Callose Synthase, GSL5, Is Required for Wound and Papillary Callose Formation [PDF]

The Plant Cell, 2003
Arabidopsis was transformed with double-stranded RNA interference (dsRNAi) constructs designed to silence three putative callose synthase genes: GLUCAN SYNTHASE-LIKE5 (GSL5), GSL6, and GSL11. Both wound callose and papillary callose were absent in lines transformed with GSL5 dsRNAi and in a corresponding sequence-indexed GSL5 T-DNA insertion line but ...

Harnessing Natural Diversity and Rational Design for Enhanced Plant Immunity

Plant, Cell &Environment, EarlyView.
ABSTRACT Plant pathogens cause crop loss. Genetic resistance, through natural genetic diversity or engineered resistance, can be highly effective in protecting plants from infection. Genetic resistance from wild relatives of crops has been successfully introduced into crops to control pathogen infection.
