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 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
Heterozygosity and segregation in Candida albicansSpringer Science and Business Media LLC - Tập 180 - Trang 107-113 - 1980
William L. Whelan, Roger M. Partridge, P. T. Magee
Strain FC18 of the pathogenic yeast Candida albicans is heterozygous at a gene required for synthesis of methionine and cysteine, and yields auxotrophic derivatives by induced mitotic segregation. Derivatives of FC18 are heterozygous at other genes. Genetic analysis of C. albicans is feasible using induced mitotic recombination.
