Regulatory interactions among the cya, crp and pts gene products in Salmonella typhimuriumSpringer Science and Business Media LLC - Tập 192 - Trang 477-486 - 1983

A well-characterized set of pts deletion mutants of Salmonella typhimurium were used to re-evaluate the purported role of the PTS in the inducer exclusion process and in regulation cAMP synthesis. During the course of these studics a class of secondary mutations was isolated which suppress the inhibition of cAMP synthesis caused by pts mutations. These suppressor mutations were traced to the crp l...... hiện toàn bộ
Structural features of DNA in competent Bacillus subtilisSpringer Science and Business Media LLC - Tập 113 - Trang 316-330 - 1971
W. J. Harris, G. C. Barr
For efficient transformation with B. subtilis, recipient cells must be grown to the state termed competence. Previous findings indicated that such competent cells contained DNA which exhibited about 5% single-strandedness. In this work, the physico-chemical properties of this DNA are compared to artificially “nicked” DNA. Evidence is presented that breakdown of the host DNA occurs during growth to...... hiện toàn bộ
Expression of resistance gene analogs in woodland strawberry (Fragaria vesca) during infection with Phytophthora cactorumSpringer Science and Business Media LLC - Tập 291 - Trang 1967-1978 - 2016

Important losses in strawberry production are often caused by the oomycete Phytophthora cactorum, the causal agent of crown rot. However, very limited studies at molecular levels exist of the mechanisms related to strawberry resistance against this pathogen. To begin to rectify this situation, a PCR-based approach (NBS profiling) was used to isolate strawberry resistance gene analogs (RGAs) with a...... hiện toàn bộ
Expression and functional analysis of genes encoding cytokinin receptor-like histidine kinase in maize (Zea mays L.)Springer Science and Business Media LLC - Tập 289 - Trang 501-512 - 2014

Cytokinin signaling is vital for plant growth and development which function via the two-component system (TCS). As one of the key component of TCS, transmembrane histidine kinases (HK) are encoded by a small gene family in plants. In this study, we focused on expression and functional analysis of cytokinin receptor-like HK genes (ZmHK) in maize. Firstly, bioinformatics analysis revealed that seve...... hiện toàn bộ
