Cells of the osteoblast lineage affect the homing and the number of long-term repopulating haematopoietic stem cells, haematopoietic stem cell mobilization and lineage determination and B cell lymphopoiesis. Osteoblasts were recently implicated in pre-leukaemic conditions in mice. However, a single genetic change in osteoblasts that can induce(More)
The gene encoding pyrethroid-hydrolyzing esterase (EstP) from Klebsiella sp. strain ZD112 was cloned into Escherichia coli and sequenced. A sequence analysis of the DNA responsible for the estP gene revealed an open reading frame of 1914 bp encoding for a protein of 637 amino acid residues. No similarities were found by a database homology search using the(More)
We have cloned a novel KRAB-related zinc finger gene, ZNF307, encoding a protein of 545aa. ZNF307 is conserved across species in evolution and is differentially expressed in human adult and fetal tissues. The fusion protein of EGFP-ZNF307 localizes in the nucleus. Transcriptional activity assays show ZNF307 suppresses transcriptional activity of(More)
Brachypodium distachyon (Brachypodium) is a temperate wild grass species and is a powerful model system for studying grain, energy, forage and turf grasses. Exploring the natural variation in the drought response of Brachypodium provides an important basis for dissecting the genetic network of drought tolerance. Two experiments were conducted in a(More)
The potential for biodegradation of aromatic hydrocarbons simultaneously at low temperatures and under saline and alkaline conditions is not well understood, but such biodegradation would be useful for remediation of polluted sites. A psychrotolerant, moderately haloalkaliphilic pure culture using benzene as a sole source of carbon and energy was isolated(More)
The pyrethroid pesticides residues on foods and environmental contamination are a public safety concern. Pretreatment with pyrethroid hydrolase has the potential to alleviate the conditions. For this purpose, a fungus capable of using pyrethroid pesticides as a sole carbon source was isolated from the soil and characterized as Aspergillus niger ZD11. A(More)
Drought is a major environmental stress limiting growth of perennial grasses in temperate regions. Plant drought tolerance is a complex trait that is controlled by multiple genes. Candidate gene association mapping provides a powerful tool for dissection of complex traits. Candidate gene association mapping of drought tolerance traits was conducted in 192(More)
Submergence stress can cause the death of grass plants. Identification of the association between molecular markers and submergence tolerance-related traits facilitates an efficient selection of the tolerant cultivars for commercial production. A global collection of 99 diverse perennial ryegrass (Lolium perenne L.) accessions was evaluated for submergence(More)
Co-inhibitory signals from the B7 superfamily have been demonstrated to induce T cell dysfunction in chronic HBV infection (CHB). However, the expression and function of Z39Ig, a new inhibitor of the B7 superfamily, is still unclear in CHB. Here immunohistochemical staining showed that Z39Ig was restricted to macrophages and that its level was decreased(More)
