Autophagy functions as an antiviral mechanism against geminiviruses in plants
Autophagy is an evolutionarily conserved process that recycles damaged or unwanted cellular components, and has been linked to plant immunity. However, how autophagy contributes to plant immunity is unknown. Here we reported that the plant autophagic machinery targets the virulence factor βC1 of Cotton leaf curl Multan virus (CLCuMuV) for degradation through its interaction with the key autopha...
متن کاملViral genome methylation as an epigenetic defense against geminiviruses.
Geminiviruses encapsidate single-stranded DNA genomes that replicate in plant cell nuclei through double-stranded DNA intermediates that associate with cellular histone proteins to form minichromosomes. Like most plant viruses, geminiviruses are targeted by RNA silencing and encode suppressor proteins such as AL2 and L2 to counter this defense. These related proteins can suppress silencing by m...
متن کاملEvolutionary History and Genome Organization of DUF1220 Protein Domains
DUF1220 protein domains exhibit the most extreme human lineage-specific (HLS) copy number increase of any protein coding region in the human genome and have recently been linked to evolutionary and pathological changes in brain size (e.g., 1q21-associated microcephaly). These findings lend support to the view that DUF1220 domain dosage is a key factor in the determination of primate (and human)...
متن کاملGenome organization and regulation
The broad-ranging topic of this Minisymposium attracted four presentations describing in vivo and in vitro experimental work and two presentations that primarily addressed theoretical aspects of chro-matin behavior over long and short length scales. Overall, the focus was very much on chromosomes, with presentations addressing chromosome ends (telomeres), centromeres, chromosome segregation , h...
متن کاملAssigning protein functions by comparative genome analysis: protein phylogenetic profiles.
Determining protein functions from genomic sequences is a central goal of bioinformatics. We present a method based on the assumption that proteins that function together in a pathway or structural complex are likely to evolve in a correlated fashion. During evolution, all such functionally linked proteins tend to be either preserved or eliminated in a new species. We describe this property of ...
