NF-YB family transcription factors in : Structure, phylogeny, and expression analysis in biotic and abiotic stresses.

Nuclear factor-Y (NF-Y) transcription factors (TFs) are conserved heterotrimeric complexes present and widespread across eukaryotes. Three main subunits make up the structural and functional aspect of the NF-Y TFs: NF-YA, NF-YB and NF-YC, which bind to the conserved CCAAT- box of the promoter region of specific genes, while also interacting with each other, thereby forming myriad combinations. The NF-YBs are expressed differentially in various tissues and plant development stages, likely impacting many of the cellular processes constitutively and under stress conditions.

Geminivirus-Derived Vectors as Tools for Functional Genomics.

A persistent issue in the agricultural sector worldwide is the intensive damage caused to crops by the geminivirus family of viruses. The diverse types of viruses, rapid virus evolution rate, and broad host range make this group of viruses one of the most devastating in nature, leading to millions of dollars' worth of crop damage. Geminiviruses have a small genome and can be either monopartite or bipartite, with or without satellites.

AC4 protein of tomato leaf curl Palampur virus is an RNA silencing suppressor and a pathogenicity determinant.

Plants deploy RNA silencing as a natural defence against invading viruses involving sequence-specific degradation of the viral RNAs. As a counter-defence strategy, viruses encode suppressor proteins that simultaneously target different steps of the silencing machinery. Tomato leaf curl Palampur virus (ToLCPalV) is a bipartite begomovirus in Geminiviridae family.

Molecular modelling, dynamics simulation and characterization of antifungal chitinase from Sechium edule.

Chitinases are varied sized proteins which have the ability to degrade chitin and are present in a huge range of organisms like fungi, yeasts, arthropods, humans etc. and have been getting increased attention due to their biocontrol properties. In silico analysis sheds light on the extensive properties of this plant protein.
