Emerging Models: MicroRNAs in jute
News Jan 01, 2014
Jute (Corchorus spp.) is an important fibre crop in South Asia. This smallholder’s crop is vulnerable to a most devastating pathogen, Macrphomina phaseolina. It causes damping off, root rot and collar rot collectively known as stem rot, which results in up to 30% yield loss and low fibre quality. The pathogen first causes root rot under high soil temperature and low soil moisture (drought) conditions and then colonises physiologically altered stem causing stem rot at maturity, under favourable weather conditions. However, the molecular mechanisms underlying are unknown. Plant-pathogen-weather interface is regulated by a number of genes. Existing, probe-dependent gene regulation analysis methods require plant and pathogen cells to be physically separated. However, probe-independent RNA sequencing method allows plant and pathogen transcripts to be analysed simultaneously.
Giant Viruses Invent Their Own GenesNews
Three new members have been isolated and added to the Pandoravirus family. This strange family of viruses, with their giant genomes and many genes with no known equivalents, surprised scientists when they were discovered a few years ago. This new study notes that pandoraviruses appear to be factories for new genes – and therefore new functions.
Therapeutic CRISPR Could Be Cancer RiskNews
Therapeutic use of gene editing with the so-called CRISPR-Cas9 technique may inadvertently increase the risk of cancer, according to a new study. Researchers say that more studies are required in order to guarantee the safety of these ‘molecular scissors’ for gene-editing therapies.
