Global Status of Phytoplasma Diseases in Vegetable Crops

Frontiers in Microbiology, 2019
The presence of phytoplasmas and their associated diseases is an emerging threat to vegetable production which leads to severe yield losses worldwide. Phytoplasmas are phloem-limited pleomorphic bacteria lacking the cell wall, mainly transmitted through ...

Changes of ultrastructure and cytoplasmic free calcium in Gladiolus x hybridus Van Houtte roots infected by aster yellows phytoplasma

Acta Societatis Botanicorum Poloniae, 2011
Roots of Gladiolus x hybridus Van Houtte plants infected with aster yellows phytoplasma were examined. The infected plants had a reduced root system in comparison to control plants.

Leafhoppers and Cixiids in Phytoplasma-infected Carrot Fields: Species Composition and Potential Phytoplasma Vectors [PDF]

Pesticidi i Fitomedicina, 2010
The first molecular analysis of samples collected in southern Bačka (Serbia) confirmed the presence of aster yellows (16SrI) and stolbur phytoplasmas (16SrXII) in insects belonging to the family Cicadellidae, as well as in carrot plants where the insects

Molecular identification of a phytoplasma naturally infecting Populus nigra L. cv. Italica trees in Croatia

Plant Protection Science, 2002
Leaf and branch samples of 10 Populus nigra L. cv. Italica trees were collected from the urban Zagreb area in late summer/autumn 2001. One of the trees exhibited leaf yellowing, overall sparse foliage, stunting and decline.

AY-WB Phytoplasma Secretes a Protein That Targets Plant Cell Nuclei

Molecular Plant-Microbe Interactions, 2009
The fully sequenced genome of aster yellows phytoplasma strain witches' broom (AY-WB; Candidatus Phytoplasma asteris) was mined for the presence of genes encoding secreted proteins based on the presence of N-terminal signal peptides (SP).

First Report of Aster Yellows Phytoplasma in Alfalfa

Plant Disease, 1999
Samples of alfalfa (Medicago sativa L.) leaves and stems showing symptoms of inter-veinal chlorosis and purpling, commonly associated with insect feeding, were collected from 8 sites in central and southern Wisconsin in autumn of 1998. Samples were frozen within 24 h of collection.

Cell Cycle‐Specific Regulation of Centrosome Clustering Dynamics in Cancer Cells by the Multifunctional Kinesin HSET

Advanced Science, EarlyView.
CDK5RAP2 associates with the kinesin HSET and forms co‐condensates. HSET motors drive the directional transport of CDK5RAP2 condensates toward microtubule minus ends. During mitosis, HSET self‐assembly further stabilizes clustered centrosomes, thereby enabling pseudo‐bipolar spindle formation in cancer cells with supernumerary centrosomes. Upon mitotic

Filamentous sieve element proteins are able to limit phloem mass flow, but not phytoplasma spread [PDF]

, 2017
In Fabaceae, dispersion of forisomes\u2014highly ordered aggregates of sieve element proteins\u2014in response to phytoplasma infection was proposed to limit phloem mass flow and, hence, prevent pathogen spread.

Engineering and Characterization of a Fluorescent Fission Yeast Arp2/3 Complex for Single Molecule Mechanistic Investigations

Cytoskeleton, EarlyView.
ABSTRACT Arp2/3 complex is a seven‐component protein complex that facilitates the assembly of branched actin filament networks by binding to pre‐existing “mother” actin filaments and initiating the nucleation of new branched “daughter” filaments. Arp2/3 complex must be activated by a nucleation promoting factor such as the WASP/Scar protein family. The
