Phloem transport limitation in Huanglongbing affected sweet orange is dependent on phloem-limited bacteria and callose

open access: yesbioRxiv, 2021
Huanglongbing (HLB), caused by Candidatus Liberibacter asiaticus (CLas), is a phloem-limited disease which disrupts citrus production in affected areas. In HLB-affected plants, phloem sieve plate pores accumulate callose, and leaf carbohydrate export is ...

Deposition of callose in wound tissue tuber of potato (Solanum tuberosum L.)

open access: yesActa Agrobotanica, 2013
Fluorescent methods were used for investigation of callose deposition in cells of wound tuber tissue of potato. Potato cultivars: Tarpan, Certa and Narew were examined. Deposition of callose in cells depended on the place of the wound, type of tissue and

De novo assembly of transcriptomes from a B73 maize line introgressed with a QTL for resistance to gray leaf spot disease reveals a candidate allele of a lectin receptor-like kinase [PDF]

open access: yes, 2020
Gray leaf spot (GLS) disease in maize, caused by the fungus Cercospora zeina, is a threat to maize production globally. Understanding the molecular basis for quantitative resistance to GLS is therefore important for food security.

Effect of boron toxicity on pollen tube cell wall architecture and the relationship of cell wall components of Castanea mollissima Blume

open access: yesFrontiers in Plant Science, 2022
Boron (B) is essential to plant development. However, excessive B is toxic to plants. This research was performed to evaluate the effects of B toxicity on cell wall architecture of Chinese chestnut (Castanea mollissima Blume) pollen tubes with emphasis ...

The Arabidopsis Malectin-Like/LRR-RLK IOS1 is Critical for BAK1-Dependent and BAK1-Independent Pattern-Triggered Immunity [PDF]

open access: yes, 2016
Plasma membrane-localized pattern recognition receptors (PRRs) such as FLAGELLIN SENSING2 (FLS2), EF-TU RECEPTOR (EFR) and CHITIN ELICITOR RECEPTOR KINASE 1 (CERK1) recognize microbe-associated molecular patterns (MAMPs) to activate pattern-triggered ...

Penicillium chrysogenum polypeptide extract protects tobacco plants from tobacco mosaic virus infection through modulation of ABA biosynthesis and callose priming

open access: yesJournal of Experimental Botany, 2021
Fungal polypeptide-induced callose priming restricts the cell-to-cell movement of tobacco mosaic virus in N. benthamiana via the ABA biosynthetic pathway.

Regulation of callose synthase activity in situ in alamethicin-permeabilized Arabidopsis and tobacco suspension cells

open access: yesBMC Plant Biology, 2009
Background The cell wall component callose is mainly synthesized at certain developmental stages and after wounding or pathogen attack. Callose synthases are membrane-bound enzymes that have been relatively well characterized in vitro using isolated ...

Delivery of Rice Gall Dwarf Virus Into Plant Phloem by Its Leafhopper Vectors Activates Callose Deposition to Enhance Viral Transmission

open access: yesFrontiers in Microbiology, 2021
Rice gall dwarf virus (RGDV) and its leafhopper vector Recilia dorsalis are plant phloem-inhabiting pests. Currently, how the delivery of plant viruses into plant phloem via piercing-sucking insects modulates callose deposition to promote viral ...

Overexpression of AtTTP affects ARF17 expression and leads to male sterility in Arabidopsis. [PDF]

open access: yesPLoS ONE, 2015
Callose synthesis is critical for the formation of the pollen wall pattern. CalS5 is thought to be the major synthethase for the callose wall. In the Arabidopsis anther, ARF17 regulates the expression of CalS5 and is the target of miR160.

Callose-associated silica deposition in Arabidopsis [PDF]

open access: yes, 2016
The mechanism of biological silicification in plants remains to be elucidated. There are strong arguments supporting a role for the plant extracellular matrix and the β-1-3-glucan, callose, has been identified as a possible template for silica deposition
