Lateral root formation, the primary way plants increase their root mass, displays developmental plasticity in response to environmental changes. The aberrant lateral root formation (alf)4-1 mutation blocks the initiation of lateral roots, thus greatly altering root system architecture. We have positionally cloned the ALF4 gene and have further characterized(More)
A factorial experimental design with two nutrient concentrations (2 and 4 mmol Nl−1 in the form of NaNO3) and five rates of daily renewal of the cultures (10%, 20%, 30%, 40% and 50%) was carried out in cyclostat, light/dark-synchronized cultures of the marine microalga Dunaliella tertiolecta Butcher. Steady-state cellular density was a linear function(More)
UNLABELLED Multiple endocrine neoplasia type 1 (MEN1) is a syndrome inherited in an autosomal dominant trait caused by the inactivation of the tumor suppressor gene MEN1. OBJECTIVE To communicate a family with a new heterozygous germ line mutation in the intronic region of MEN1 gene and to study its influence in the menin expression. PATIENTS AND(More)
ITS and SCAR molecular markers were used to identify Monilinia species in 21 fungal isolates from infected peaches in four Ecuadorian provinces. The results confirmed Monilinia fructicola as the causal agent of brown rot in the analysed samples. This is the first report that uses molecular methods to identify this pathogen in Ecuadorian peach crops.
Streptococcus agalactiae, the aetiological agent of streptococcosis in fish, is an important pathogen of cultured and wild fish worldwide. To gain a better understanding of the pathogenesis of streptococcosis in Nile tilapia (Oreochromis niloticus), and to identify the experimental route of infection that most closely mimics natural disease, fingerlings(More)
