Attempts to identify Cassava Brown Streak Virus in western Democratic Republic of Congo [PDF]

, 2020
Open Access ArticleRoot necrosis similar to those of the cassava brown streak disease (CBSD) were observed on cassava in western provinces of the Democratic Republic of Congo (DR.Congo) in the early 2000’s. However molecular laboratory diagnosis were not

Magnesium Chlorosis of Tomatoes [PDF]

Nature, 1946
THE summary in Nature1 of the paper by Walsh and Clarke2 directs attention to the methods of treating tomato plants affected by induced magnesium deficiency. The paper emphasizes the importance in this connexion of the potash level in the soil, a relationship which was previously described by Cromwell and Hunter3, and a review of the position may be ...

Anholocyclic overwintering of Myzus persicae: Host plant selection as a driver for aphid performance and survival

Annals of Applied Biology, EarlyView.
The green peach aphid, Myzus persicae, is the main virus vector in sugar beet. We examine its performance on potential winter hosts as well as the host selection and overwintering success of anholicyclic aphids in order to improve forecasting models for virus outbreaks through targeted monitoring of suitable winter hosts. Abstract Virus yellows (VY) is

Effects of Phytoplasma Infection on Aster Leafhopper (Macrosteles quadrilineatus) Settling Behavior and Development on Brassica napus

Entomologia Experimentalis et Applicata, EarlyView.
Aster yellows phytoplasma (AYp) infection alters host plant preference in aster leafhoppers (Macrosteles quadrilineatus), with infected vectors showing a significant preference for AYp‐infected canola (Brassica napus) early in the infection period. However, this preference fades as infection progresses. Despite early attraction, B.

Identification of a Dominant Chlorosis Phenotype Through a Forward Screen of the Triticum turgidum cv. Kronos TILLING Population

Frontiers in Plant Science, 2019
Durum wheat (Triticum turgidum) derives from a hybridization event approximately 400,000 years ago which led to the creation of an allotetraploid genome.

Evolution of molecular communication in the permanent Azolla symbiosis

New Phytologist, EarlyView.
Summary Heritable symbioses exist across eukaryotes with different degrees of intimacy. In most cases, the symbionts are obligate and require inheritance for their survival. On the host side, symbiont retention can facilitate fitness benefits. Only rarely are these symbioses interwoven to the point that host survival relies on the symbiont.

Characterization of transgenic Poncirus trifoliata overexpressing the ferric chelate reductase gene CjFRO2 from Citrus junos

Biologia Plantarum, 2015
Iron deficiency chlorosis occurs frequently in calcareous soils. The transformation of plants with ferric chelate reductase genes (FROs) provides a potential strategy to alleviate plant chlorosis under iron deficiency.

Defender or accomplice? Dual roles of plant vesicle trafficking in restricting and enabling geminiviral systemic infection

New Phytologist, EarlyView.
Summary The vesicle trafficking system enables multidirectional cargo fluxes between endomembrane compartments. However, vesicle trafficking plays dual roles during pathogen infections. In plants, it mediates autophagic immune responses but can also be hijacked by pathogens to facilitate successful infections.

A new root-knot nematode, Meloidogyne moensi n. sp. (Nematoda : Meloidogynidae), parasitizing Robusta coffee from Western Highlands, Vietnam [PDF]

, 2019
A new root-knot nematode, parasitizing Robusta coffee in Dak Lak Province, Western Highlands of Vietnam, is described as Meloidogyne moensi n. sp. Morphological and molecular analyses demonstrated that this species differs clearly from other previously ...
