Fusarium rot caused by Fusarium oxysporum f.sp. gladioli (Fog) is one of the most serious diseases of Gladiolus, both in the field and in bulbs in storage. In order to study the mechanisms of pathogenesis of this fungus, we have transformed Fog with Agrobacterium tumefaciens binary vectors containing the hygromycin B phosphotransferase (hph) gene and… (More)
Myeloproliferative neoplasms (MPN) are a diverse group of chronic hematological disorders that involve unregulated clonal proliferation of white blood cells. Sevearl of them are associated with mutations in receptor tyrosine kinases or cytokine receptor associated tyrosine kinases rendering them independent of cytokine-mediated regulation. Classically they… (More)
ESCs undergo drastic changes in chromatin states during differentiation. Two recent papers in Cell (Li et al., 2012) and Cell Stem Cell (Hu et al., 2013) demonstrate that histone variant H2A.Z plays essential roles in this process by preconfiguring nucleosomes for depletion and recruiting transcription cofactors to cis-regulatory elements.
construction of gene cassette harboring HMW glutenin gene of wheat driven by γ-kafirin promoter of sorghum ABStrAct Modern biological tools of genetic engineering and biotechnology can allow transfer of gene(s) across crop species. The r-DNA technology has tremendous potential to transfer bread making character of bread wheat into sorghum by transferring… (More)
DNA double-strand breaks (DSBs) activate a canonical DNA damage response, including highly conserved cell cycle checkpoint pathways that prevent cells with DSBs from progressing through the cell cycle. In developing B cells, pre-B cell receptor (pre-BCR) signals initiate immunoglobulin light (Igl) chain gene assembly, leading to RAG-mediated DNA DSBs. The… (More)
OBJECTIVE Periodontitis is known to have multifactorial etiology, involving interplay between environmental, host and microbial factors. The current treatment approaches are aimed at reducing the pathogenic microorganisms. Administration of beneficial bacteria (probiotics) has emerged as a promising concept in the prevention and treatment of periodontitis.… (More)
RAG-mediated DNA double-strand breaks activate a cell type-specific checkpoint to inhibit pre-B cell receptor signals.
Mycobacterium tuberculosis the causative agent of tuberculosis affects millions of people worldwide. New tools for treatment and prevention of tuberculosis are urgently needed. We previously showed that a ferritin (bfrB) mutant of M. tuberculosis has altered iron homeostasis and increased sensitivity to antibiotics and to microbicidal effectors produced by… (More)
Three antifungal genes, a non-heme chloroperoxidase from Pseudomonas pyrrocinia, and an exochitinase and endochitinase from Fusarium venetanum under regulation by the CaMV 35S promoter, were used to transform Gladiolus for resistance to Fusarium oxysporum f. sp. gladioli. Gladiolus plants were confirmed to be transgenic by Southern hybridization.… (More)
