Cytoplasmic male sterility in sunflower is correlated with the co-transcription of a new open reading frame with the atpA geneSpringer Science and Business Media LLC - Tập 227 - Trang 369-376 - 1991

The organization and expression of the mitochondrial (mt) genome of fertile, male-sterile and restored lines of Helianthus annuus and of H. petiolaris were compared to identify alterations which might lead to cytoplasmic male sterility (CMS). The mtDNAs of fertile and male-sterile lines differ by an 11 kb inversion and a 5 kb insertion. The rearrangements seem to be the result of recombination eve...... hiện toàn bộ
Correlation between restriction map, genetic map and catalytic functions in the gene complex URA2Springer Science and Business Media LLC - Tập 209 - Trang 283-289 - 1987
S. Potier, J. L. Souciet, F. Lacroute
We replaced the URA2 gene by six different deleted alleles constructed in vitro by Bg/II digestion in order to correlate the genetic map with the restriction map and to define the regions coding for the different functions of the carbamylphosphate synthetase — aspartate transcarbamylase complex (CPSase-ATCase). We also enlarged the collection of ura2 point mutations by using a positive selection m...... hiện toàn bộ
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
Mig1 localization exhibits biphasic behavior which is controlled by both metabolic and regulatory roles of the sugar kinasesSpringer Science and Business Media LLC - Tập 295 - Trang 1489-1500 - 2020

Glucose, fructose and mannose are the preferred carbon/energy sources for the yeast Saccharomyces cerevisiae. Absence of preferred energy sources activates glucose derepression, which is regulated by the kinase Snf1. Snf1 phosphorylates the transcriptional repressor Mig1, which results in its exit from the nucleus and subsequent derepression of genes. In contrast, Snf1 is inactive when preferred c...... hiện toàn bộ
