Notch receptors and ligands are type I transmembrane proteins that regulate development and differentiation during cell-cell contact. There are four Notch receptor homologues and five notch ligands, identified in humans ...

LFY of Arabidopsis is a member of a unique plant specific transcription factor family. It is involved in giving meristem a determinate floral fate by the activation of floral organ identity genes and preventing inflorescence ...

Rice have highly derived florets borne on a short branch called ‘spikelet’ comprised of a pair of rudimentary glumes and sterile lemma (empty glumes) that subtends a single fertile floret. The floral organs consist of a ...

A steady state level of negative supercoiling is essential for chromosome condensation, initiation of replication and subsequent elongation step. DNA gyrase, found in every eubacteria, serves the essential housekeeping ...

Regulation of transcription initiation is the major determining event employed by the cell to control gene expression and subsequent cellular processes. The weak promoters, with low basal transcription activities, are ...

Restriction modification (R-M) systems are important components of the prokaryotic arsenal against invading genomes. R-M systems directly target the foreign DNA and are often considered as primitive immune systems in ...

Packaging of genomic DNA by proteins and super coiling into chromatin and chromatin-like structures (in bacteria) influences nearly all nuclear process such as replication, transcription, repair, and recombination. A ...
