Bioassays of a Cordyceps sp. Isolate as a Candidate Mycoinsecticide Against Bemisia tabaci MEAM1 Adults

Entomological Research, Volume 55, Issue 12, December 2025.
ABSTRACT The whitefly Bemisia tabaci MEAM1 (Gennadius) (Hemiptera: Aleyrodidae) is a major agricultural pest that infests a wide range of crops and transmits several plant viruses, leading to significant yield losses worldwide. The intensive use of chemical insecticides for its control has contributed to the development of resistance, highlighting the ...

Virus‐Inducible Activation of Hypersensitive Response Confers Broad‐Spectrum Resistance to Diverse Viruses in Plants

Molecular Plant Pathology, Volume 26, Issue 12, December 2025.
Using a virus‐inducible promoter to drive the expression of the Avr4/Cf‐4 gene pair can trigger a hypersensitive response upon viral infection, which confers plants broad‐spectrum resistance to geminiviruses. ABSTRACT The hypersensitive response (HR) is a powerful plant defence mechanism that restricts pathogen spread through localised cell death ...

A TIR‐NLR gene from Arabidopsis Pla‐1 confers resistance to geminivirus infection

The Plant Journal, Volume 124, Issue 5, December 2025.
SUMMARY Geminiviruses are single‐stranded DNA viruses that infect many plant species and cause serious losses in agronomically important crops. An earlier study showed that the Arabidopsis thaliana ecotype Pla‐1 is resistant to infection by diverse geminivirus species and mapped the major resistance locus Geminivirus Resistance of Pla‐1 1 (GRP1) to ...

Gradual Emergence of East African cassava mosaic Cameroon virus in Cassava Farms in Côte d’Ivoire

Agronomy
Cassava mosaic disease (CMD) and cassava brown streak disease (CBSD) are endemic threats to cassava production, causing significant yield losses. They are caused respectively by begomoviruses and ipomoviruses that are transmitted by whiteflies and ...

Sense- and antisense-mediated resistance against Sri Lankan cassava mosaic virus (SLCMV) in Nicotiana benthamiana

Biologia Plantarum, 2019
Sri Lankan cassava mosaic virus (SLCMV) is the principal causal agent of cassava mosaic disease in the Indian subcontinent. To gain resistance against the virus, the coat protein (CP) gene, namely the AV1 of SLCMV-Adivaram isolate, was cloned in either ...

Assessment of genetically modified cotton GHB614 × T304‐40 × GHB119 × COT102 (application EFSA‐GMO‐ES‐2017‐147)

EFSA Journal, Volume 23, Issue 12, December 2025.
Abstract Genetically modified cotton GHB614 × T304‐40 × GHB119 × COT102 was developed by crossing to combine four single events: GHB614, T304‐40, GHB119 and COT102. The four‐event‐stack cotton expresses 2mEPSPS, Cry1Ab, Cry2Ae, Vip3Aa19 and PAT/bar to confer herbicide tolerance and insect resistance.

Assessment of genetically modified cotton T304‐40 × GHB119 × COT102 (application EFSA‐GMO‐BE‐2018‐155)

EFSA Journal, Volume 23, Issue 12, December 2025.
Abstract Genetically modified cotton T304‐40 × GHB119 × COT102 was developed by crossing to combine three single events: T304‐40, GHB119 and COT102. The three‐event stack cotton expresses Cry1Ab, Cry2Ae, Vip3Aa19 and PAT/bar to confer herbicide tolerance and insect resistance.

Towards understanding factors that govern fertilizer response in casave: lessons from East Africa [PDF]

Information on fertilizer response in cassava in Africa is scarce. We conducted a series of on-farm and on-station trials in two consecutive years to quantify yield responses of cassava to mineral fertilizer in Kenya and Uganda and to evaluate factors ...
