Genetic diversity and phylogeography of cassava mosaic geminiviruses in Madagascar. [S02-12] [PDF]
, 2012 Cassava mosaic disease (CMD) caused by cassava mosaic geminiviruses (CMGs, Geminiviridae) is a major threat on cassava production throughout Africa. In Madagascar, severe symptoms with high prevalence of CMD were observed.

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 ...

Endogenous caulimovirid sequences are widespread in plant genomes [PDF]
, 2010 Endogenous sequences from members of the Caulimoviridae and Geminiviridae families have been identified in the genome of several plant species. They are thought to result from illegitimate recombination events and are generally replication-defective ...

Twenty years of cucurbit breeding research at the World Vegetable Center
Crop Science, Volume 65, Issue 6, November/December 2025.Abstract The contribution of cucurbit crops to global food and nutrition security is immense. They are economically and nutritionally important to smallholder farmers in Asia, who account for 81% of global cucurbit production. World Vegetable Center (WorldVeg) has been focused for 20 years on four species: bitter gourd (Momordica charantia), ridge ...

Extension of the viral ecology in humans using viral profile hidden Markov models. [PDF]
PLoS ONE, 2018 When human samples are sequenced, many assembled contigs are "unknown", as conventional alignments find no similarity to known sequences. Hidden Markov models (HMM) exploit the positions of specific nucleotides in protein-encoding codons in various ...
