Filtration enrichment method for isolation of auxotrophic mutants of Trichoderma harzianum rifai
(Sociedade Brasileira de Microbiologia, 1999-01-01)
A obtenção de marcas genéticas, quer sejam para resistência a drogas, quer para auxotrofia, é uma etapa trabalhosa mas importante em pesquisa genética. Esse trabalho visou a obtenção de mutantes auxotróficos de Trichoderma ...
Response of photomorphogenic tomato mutants to nutrient omissions
(2021-07-01)
Light is a critical environmental factor that influences nutrient uptake, but understanding how light acts on nutrient uptake is still very elusive. To verify the role of opposite light responses in accumulation, nutrient ...
Isolation and characterisation of cycloheximide sensitive mutants of Aspergillus nidulans
(Springer, 1998-01-01)
Aspergillus nidulans is a non-pathogenic fungus with well-developed genetics which provides an excellent model system for studying different aspects of drug resistance in filamentous fungi. As a preliminary step to ...
Disarming mutant p53 oncogenic function
(Elsevier, 2013-11)
In the last decade intensive research has confirmed the long standing hypothesis that some p53 point mutants acquire novel activities able to cooperate with oncogenic mechanisms. Particular attention has attracted the ...
Inducao de mutacao in vivo, no melhoramento de crisantemo (Dendranthema grandiflora Tzvelev) cv. repin rosa.
(Pesquisa Agropecuaria Brasileira, Brasilia, v.32, n.11, p.1153-58, nov.1997., 1997)
Parasexuality in asexual development mutants of Aspergillus nidulans
(Sociedad de Biología de Chile, 2006)
Salmonella antibiotic-mutant strains reduce fecal shedding and organ invasion in broiler chicks
(POULTRY SCIENCE ASSOC INC, 2010)
We investigated the exposure to antibiotics in the production of antibiotic-mutant strains of Salmonella. Ten isolates of poultry origin were assayed for antibiotic susceptibilities. One strain of Salmonella Enteritidis, ...
Catalase-peroxidase activity is decreased in a Caulobacter crescentus rho mutant
(WILEY-BLACKWELL PUBLISHING, INC, 2010)
A Caulobacter crescentus rho:Tn5 mutant strain presenting a partially functional transcription termination factor Rho is highly sensitive to hydrogen peroxide in both exponential and stationary phases. The mutant was shown ...
