Callose (β-1,3 glucan) is essential for Arabidopsis pollen wall patterning, but not tube growth [PDF]
, 2005 Background: Callose (β-1,3 glucan) separates developing pollen grains, preventing their underlying walls (exine) from fusing. The pollen tubes that transport sperm to female gametes also contain callose, both in their walls as well as in the plugs that ...

T-loop phosphorylation of Arabidopsis CDKA;1 is required for its function and can be partially substituted by an aspartate residue [PDF]
, 2007 As in other eukaryotes, progression through the cell cycle in plants is governed by cyclin-dependent kinases. Phosphorylation of a canonical Thr residue in the T-loop of the kinases is required for high enzyme activity in animals and yeast.

Journal of the Science of Food and Agriculture, EarlyView.Abstract The papaya tree (Carica papaya L.), native to the Americas, is cultivated in tropical regions and holds substantial economic importance, with an estimated export volume of 365 000 t in 2023. However, diseases caused by viruses, fungi, bacteria, and nematodes can lead to severe losses.

Ecology and Evolution, 2018 Silicon (Si) uptake by Poaceae plants has beneficial effects on herbivore defense. Increased plant physical barrier and altered herbivorous feeding behaviors are documented to reduce herbivorous arthropod feeding and contribute to enhanced plant defense.

Engineering of Bioenergy Crops: Dominant Genetic Approaches to Improve Polysaccharide Properties and Composition in Biomass. [PDF]
, 2020 Large-scale, sustainable production of lignocellulosic bioenergy from biomass will depend on a variety of dedicated bioenergy crops. Despite their great genetic diversity, prospective bioenergy crops share many similarities in the polysaccharide ...

Calcium signaling in plant defense
New Plant Protection, EarlyView.Calcium signaling acts as a central hub in plant immunity, translating pathogen perception into defense responses. This review highlights the channels, sensors, and signaling networks involved, and discusses how pathogens subvert calcium dynamics, as well as how this knowledge may inspire innovative strategies for engineering durable crop resistance ...

Characteristics of dynamic changes of the callose in male sterile anthers of Lycium barbarum L.
Xibei zhiwu xuebao[Objective] Callose is a beta-1, 3-bonded glucan that forms a wall structure, which occurs only in certain tissues. When degrading prematurely or delayed, it may lead to pollen abortion.

Crop Journal, 2022 The main defense response to Soybean mosaic virus (SMV) infection in soybean [Glycine max (L.) Merr.] is thought to be blockage of intercellular virus transport by callose deposition on plasmodesmata. But the specific regulatory mechanism remains largely
