Abstract This study investigates responses of clonal plants and non-clonal to drought their competition results using a spatial simulator based on nonclonal life history strategies. The are designed as two phenotypes one generic species with facultative growth. Therefore, both share the same histories beside allocation aboveground belowground growth, resulting in differences leaf biomass, under...

the dry bubble disease, caused by lecanicillium fungicola, is an important fungal disease of white button mushroom in iranian mushroom production farms. twenty-three isolates of the pathogen collected in iran and identified as l. fungicola var. fungicola, were compared for genetic polymorphism, diversity in growth rate and virulence. ten universal rice primers (urp) were used to evaluate the ge...

Spontaneous hybrids between alien and native plant species are taxa they threaten biodiversity due to their high competitive ability or introgression. Thus, we tested the effect of soil conditions, elevation type ramet clusters (clonal clumps shoots) on sexual asexual ramets Solidago × niederederi , a hybrid invasive S. canadensis virgaurea . We also relationships size habitat conditions in its...

If the acquisition of virulence genes (VGs) for pathogenicity were not solely acquired through horizontal gene transfers of pathogenicity islands, transposons, and phages, then clonal clusters of enterotoxigenic Escherichia coli (ETEC) would contain few or even none of the VGs found in strains responsible for extraintestinal infections. To evaluate this possibility, 47 postweaning diarrhea (PWD...

Clonal heterogeneity in lymphoid malignancies has been recently reported in adult T-cell lymphoma/leukemia, peripheral T-cell lymphoma, not otherwise specified, and mantle cell lymphoma. Our analysis was extended to other types of lymphoma including marginal zone lymphoma, follicular lymphoma and diffuse large B-cell lymphoma. To determine the presence of clonal heterogeneity, 332 cases were ex...

Current prognostic indicators such as age, sex, and white blood cell count (WBC) fail to identify all children with more aggressive forms of B-precursor acute lymphoblastic leukemia (ALL), and a proportion of patients without poor prognostic indicators still relapse. Results obtained from an analysis of 65 pediatic B-precursor ALL patients indicated that subclone formation leading to clonal div...

Seventy-five clonal populations of morphologically transformed 10T1/2 cells were established from independent Type II and Type III foci that were of spontaneous origin or were induced by the carcinogenic agents N-methyl-N'-nitro-N-nitrosoguanidine, benzo(a)pyrene diol epoxide-I, and 3-methylcholanthrene. Clonal populations were characterized for expression of selected transformation phenotypes,...

Seventy-five clonal populations of morphologically transformed 10T1/2 cells were established from independent Type II and Type III foci that were of spontaneous origin or were induced by the carcinogenic agents jV-methyl-JV'-nitro-jV-nitrosoguanidine, benzo(a)pyrene diol epoxide-I, and 3-methylcholanlhrene. Clonal populations were characterized for ex pression of selected transformation phenoty...

BACKGROUND Substance consumption (SC) begins in adolescence and has been linked to protection factors such as family relationships (FR) and positive parenting (PP). There are few studies concerning the effectiveness of prevention programs based on the family, even though assessing interventions is one of the objectives of preventive science. The aim of this study was to analyze the evidence on ...
