Small RNA-based feedforward loop with AND-gate logic regulates extrachromosomal DNA transfer in Salmonella
(National Academy of Sciences, 2015)
Horizontal gene transfer via plasmid conjugation is a major driving force in microbial evolution but constitutes a complex process that requires synchronization with the physiological state of the host bacteria. Although ...

Neddylation inhibits CtIP-mediated resection and regulates DNA double strand break repair pathway choice
(Oxford University Press, 2015)
DNA double strand breaks are the most cytotoxic lesions that can occur on the DNA. They can be repaired by different mechanisms and optimal survival requires a tight control between them. Here we uncover protein deneddylation ...

Epigenetic control of O-antigen length in Salmonella entérica
(2016-01-12)
El locus STM2209-STM2208 (opvAB) es exclusivo de Salmonella enterica y presenta características típicas de genes adquiridos por transferencia horizontal. Fue descrito inicialmente como un locus reprimido por metilación ...

Functional Characterization of Lysophosphatidylcholine: Acyl-CoA Acyltransferase Genes From Sunflower (Helianthus annuus L.)
(MDPI, 2020)
Lysophosphatidylcholine acyltransferase (LPCAT, EC 2.3.1.23) is an evolutionarily conserved key enzyme in the Lands cycle that catalyzes acylation of lysophosphatidylcholine (LPC) to produce phosphatidylcholine (PC), the ...

Nuevos mecanismos moleculares de regulación de la carotenogénesis en Fusarium oxysporum.
(2018-12-12)
El género Fusarium comprende cientos de especies de hongos patógenos y saprófitos, que poseen usualmente un complejo metabolismo secundario. Éste incluye la producción de carotenoides, pigmentos terpenoides que proporcionan ...

Microscopic and transcriptome analyses of early colonization of tomato roots by "Trichoderma harzianum".
(Institut d´Estudis Catalans, 2007)
The capacity of the fungus Trichoderma harzianum CECT 2413 to colonize roots and stimulate plant growth was analyzed. Tobacco seedlings (Nicotiana benthamiana) transferred to Petri dishes inoculated with T. harzianum ...

Chromosomal Position of Ribosomal Protein Genes Affects Long-Term Evolution of Vibrio cholerae
(American Society for Microbiology, 2023)
It is unclear how gene order within the chromosome influences genome evolution. Bacteria cluster transcription and translation genes close to the replication origin (oriC). In Vibrio cholerae, relocation of s10-spc-α locus ...

Changes of ploidy during the Azotobacter vinelandii growth cycle
(American Society for Microbiology, 1994)
The size of the Azotobacter vinelandii chromosome is ~4,700 kb, as calculated by pulsed-field electrophoretic separation of fragments digested with the rarely cutting endonucleases SpeI and SwaI. Surveys of DNA content per ...

Mutantes de la fotoadaptación en Neurospora crassa
(2008)
El objetivo de esta Tesis es comenzar la disección genética del mecanismo de adaptación a la luz. Para ello pretendemos poner a punto un método de selección genética utilizando estirpes con fusiones transcripcionales y ...
