Role of mitochondrial farnesyltransferase gene in the prevention of the food spoilage fungi Aspergillus flavus by the antimicrobial natural preservative perillaldehyde.

Researchers investigated the role of Cox10, an enzyme in the heme A synthesis pathway, in the growth and drug resistance of Aspergillus flavus. Deletion of cox10 affects growth and development, increases drug resistance, and triggers stress responses. Understanding these molecular mechanisms could help develop antifungal agents against A. flavus contamination.

Genome-Wide Identification and Characterization of Major RNAi Genes Highlighting Their Associated Factors in Cowpea (Vigna unguiculata (L.) Walp.).

This study identified 28 VuRNAi genes in cowpea that play a role in protecting the plant from biotic and abiotic stresses. These genes can contribute to improved grain quality, immunity, and resistance to pathogens, salinity, and drought. The findings will help develop more resilient cowpeas.

Genome sequencing of Syzygium cumini (jamun) reveals adaptive evolution in secondary metabolism pathways associated with its medicinal properties.

Scientists sequenced the genome and transcriptome of a medicinal tree, revealing neopolyploidy and adaptive evolution in genes involved in secondary metabolite biosynthesis and stress tolerance mechanisms. This information is relevant for understanding the pharmacological properties of the tree, including its anti-diabetic effects.

Begomovirus and DNA-satellites association with mosaic and leaf curl disease of Solanum nigrum and Physalis minima: the new hosts for chilli leaf curl virus.

The researchers collected plants with mosaic, enation, and leaf curl symptoms. They confirmed begomovirus infection and identified a novel betasatellite. These plants could serve as reservoir hosts for infecting chili plants.

Agroinfiltration-based transient genome editing for targeting phytoene desaturase gene in kinnow mandarin (C. reticulata Blanco).

Researchers used CRISPR/Cas9 technology to edit the genome of kinnow mandarin, a type of citrus crop. They successfully knocked out the phytoene desaturase gene, resulting in albino patches. This method provides a way to study and genetically transform kinnow mandarin in the future.

Effects of RNA silencing during antagonism between citrus exocortis viroid and citrus bark cracking viroid in Etrog citron (Citrus medica).

This study explored the antagonism between Citrus exocortis viroid (CEVd) and citrus bark cracking viroid (CBCVd) in mixed infections. When CBCVd was inoculated before CEVd, it reduced CEVd levels and symptoms. RNA silencing likely plays a role in this interaction, providing insights into long noncoding RNAs in woody plants.
