Paleomicrobiology: Tracking the past microbial life from single species to entire microbial communities

Microbial Biotechnology, Volume 17, Issue 1, January 2024.
By deciphering information encoded in degraded ancient DNA extracted from up to million years‐old samples, molecular paleomicrobiology objectively retrace the temporal evolution of individual microbial species and also of complex communities (either host‐associated or free living).

Cassava molecular genetics and genomics for enhanced resistance to diseases and pests

Molecular Plant Pathology, Volume 25, Issue 1, January 2024.
Combating cassava diseases and pests requires a holistic approach that combines traditional breeding methods, genomics and biotechnology innovations such as conventional genetic engineering and genome editing. Abstract Cassava (Manihot esculenta) is one of the most important sources of dietary calories in the tropics, playing a central role in food and

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 ...

Phenotypes and Functional Effects Caused by Various Viral RNA Silencing Suppressors in Transgenic Nicotiana benthamiana and N. tabacum

Molecular Plant-Microbe Interactions, 2008
RNA silencing suppressor genes derived from six virus genera were transformed into Nicotiana benthamiana and N. tabacum plants. These suppressors were P1 of Rice yellow mottle virus (RYMV), P1 of Cocksfoot mottle virus, P19 of Tomato bushy stunt virus ...

Reinfection Dynamics of Disease-Free Cassava Plants in Three Agroecological Regions of Côte d’Ivoire

Viruses
Cassava mosaic disease (CMD) is caused by begomoviruses and can result in yield losses of up to 90% in susceptible varieties. Using disease-free planting material from in vitro cultures is one of the most effective ways of controlling this disease. A CMD

Molecular Diversity and Distribution of Whiteflies (Bemisia tabaci) in Cassava Fields Across South West and North Central, Nigeria

Insects
Whitefly Bemisia tabaci (Gennadium, Hemiptera) causes severe damage to cassava plants through excessive feeding on leaves and transmitting viruses, such as African cassava mosaic virus (ACMV), East African cassava mosaic virus (EACMV), and ipomoviruses ...

Response of cassava cultivars to African cassava mosaic virus infection across a range of inoculum doses and plant ages.

PLoS ONE, 2019
Cassava production in Africa is constrained by cassava mosaic disease (CMD) that is caused by the Cassava mosaic virus (CMV). The aim of this study was to evaluate the responses of a range of commonly cultivated West African cassava cultivars to varying ...

Cassava mosaic disease in Burkina Faso: epidemiological aspects and disease management perspectives

Discover Agriculture
Cassava Mosaic Disease (CMD) is the main biotic constraint to cassava production in West Africa. In Burkina Faso, efforts are underway to manage it sustainably using classical surveillance, including field monitoring and laboratory diagnosis.
