Food for thought: how nutrients regulate root system architecture [PDF]

, 2017
The spatial arrangement of the plant root system (root system architecture, RSA) is very sensitive to edaphic and endogenous signals that report on the nutrient status of soil and plant.

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

bioRxiv, 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.)

Acta 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

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

Frontiers 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 ...

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

Journal 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.

Chitin perception in plasmodesmata characterizes submembrane immune-signaling specificity in plants [PDF]

, 2020
The plasma membrane (PM) is composed of heterogeneous subdomains, characterized by differences in protein and lipid composition. PM receptors can be dynamically sorted into membrane domains to underpin signaling in response to extracellular stimuli.

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

Frontiers 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 ...

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

BMC 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 ...

Transgenic tobacco plants expressing the Potato virus X open reading frame 3 gene develop specific resistance and necrotic ring symptoms after infection with the homologous virus [PDF]

, 2001
Tobacco plants were transformed with the open reading frame 3 gene from Potato virus X (PVX) coding for the p12 protein. Although the transgenic plants exhibited a normal morphological aspect, microscopic examination revealed extensive alterations in ...

DCET1 Controls Male Sterility Through Callose Regulation, Exine Formation, and Tapetal Programmed Cell Death in Rice

Frontiers in Genetics, 2021
In angiosperms, anther development comprises of various complex and interrelated biological processes, critically needed for pollen viability. The transitory callose layer serves to separate the meiocytes.
