Silicon amendment to rice plants contributes to reduced feeding in a phloem‐sucking insect through modulation of callose deposition

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.

Genomic insights into the local adaptation of spontaneous olive trees in the Mediterranean Basin highlight the need for conservation planning in the face of global change

PLANTS, PEOPLE, PLANET, EarlyView.
The Mediterranean Basin, a major biodiversity hotspot, is highly vulnerable to climate and global changes. Wild olive trees form an essential part of this landscape and hold strong ecological, cultural and socio‐economic significance. By examining how these trees responded to past climatic conditions, this study shows adaptation of olive trees to local

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.

Callose (β-1,3 glucan) is essential for Arabidopsis pollen wall patterning, but not tube growth

BMC Plant Biology, 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 ...

Crossed-leg callosities

Acta Dermato-Venereologica, 1985
We report five patients in whom localised callosities were found on the dorsum of the feet. This was bilateral in four cases and was due to repetitive minor trauma associated with the sitting posture adopted by the patients. Three of the patients also had psoriasis vulgaris which was clinically dissimilar to the lesions we describe.

First genome sequence of a European Alternaria brassicae isolate and genes involved in early development of alternaria leaf spot on Brassica juncea

Pest Management Science, EarlyView.
This article reports the first genome sequence of a UK Alternaria brassicae isolate. Dual RNA‐sequencing profiling of A. brassicae‐infected Brassica juncea leaves identified differentially expressed genes involved in pathogenicity and host response pathways in moderately resistant Sej‐2 (2) and moderately susceptible Pusa Jaikisan cultivars.

An efficient method for the extraction and the quantitative determination of callose from HLB-affected and healthy citrus

Frontiers in Agronomy
Callose is a 1,3-β glucan responsible for several processes in planta such as cell division, ripening of pollen mother cells, maintaining the plasmodesmata opening, and providing structure to the sieve plates.

Callose formation in injured cells of the vegetative and generative thallus of Chara vulgaris L. Absence of callose in the process of cytodifferentiation

Acta Societatis Botanicorum Poloniae, 2014
In an alga Chara vulgaris L. the processes of differentiation of vegetative system cells of the thallus, and initiation and development of generative organs are not associated with callose formation.

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

Insect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

A hypothesis concerning callose [PDF]

Plant Signaling & Behavior, 2018
Background Concept: Certain proteins and the glucose monomer have spacing of their carbonyl oxygen atoms that match the spacing of the oxygen atoms of hexagonal ice. This opens the possibility that a sequence of linked glucose residues may have a sequence of equally spaced carbonyl oxygen atoms.
