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 ...

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 ...

Abrin is a potent toxin obtained from the seeds of Abrus precatorius. It is a heterodimeric glycoprotein consisting of an A and a B subunit linked together by a disulfide bond. The toxicity of the protein comes from the A ...

In the eukaryotic nucleus, an immense length of DNA is compactly packaged to generate an ordered three-dimensional hierarchical structure called chromatin (van Holde, 1988; Wolffe, A.P, 1998). This organization forms a ...

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 ...

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 ...

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 ...
