to study the molecular basis for resistance of lolium rigidum populations (from fars province) to aryloxyphenoxy propionate herbicide through dcaps method, an experiment was conducted at the biotechnology laboratory of shiraz university. eighteen populations of l. rigium suspected of herbicide resistance, from zarghan, fasa. noorabad and firoozabad areas which had survived a recomended dose of ...

The quantitative trait locus (QTL) mapping in segregating crosses of NSY (Nagoya-Shibata-Yasuda) mice, an animal model of type 2 diabetes, with nondiabetic strain C3H/He mice has identified diabetogenic QTLs on multiple chromosomes. The QTL on chromosome 11 (Chr11) (Nidd1n) showing the largest effect on hyperglycemia was confirmed by our previous studies with homozygous consomic mice, C3H-11(NS...

In this study, it was attempted to determine the resistance of different tomato lines spotted wilt virus (TSWV), yellow leaf curl (TYLCV), and root-origin nematodes (Meloidogyne spp.) using molecular DNA markers. For purpose, out 96 be tested, Sw5-2 for ripening Ty3P6-25 (TYLCV) marker Mi23, which determines root-knot spp.), were used by PCR. Ty3P6-25, that TYLCV, found susceptible (rr) in 34 l...

Selectively outbred Dahl salt-sensitive (DS) and salt-resistant (DR) rats were compared with the inbred Dahl salt-sensitive (SS/Jr) and salt-resistant (SR/Jr) rats developed from the original Brookhaven stocks by J.P. Rapp. The animals were evaluated for genotype at the renin locus. The inbred strains are uniformly homozygous for their respective alleles, s in SS/Jr and r in SR/Jr. DR rats were...

Horse gram is one of the lesser-known beans widely grown in India. One hundred and twenty-three homozygous horse mutants were screened for powdery mildew (PM) disease resistance using grade 0 to 4. The grouped based on level 2 (resistant) susceptible (3 4). PM altered chlorophyll fluorescence (a/b ratio), maturity duration, yield attributing traits. loss ranged from 4.55% 72.66%. After affirmin...

The present study was aimed to assess the bedbugs susceptibility to pyrethroid insecticides using molecular analysis. With the aid of pest control companies, adult bedbugs were collected from various places such as hotels, residential houses, and industrial buildings in seven cities highly crowded with domestic and foreign tourists in Iran from May 2016 to August 2017. Bedbugs ...

In Arkansas, resistance to protoporphyrinogen IX oxidase (PPO)-inhibiting herbicides in Amaranthus palmeri S. Wats. is mainly due target site mutations. Although A. PPO-mutations are well investigated, the cross-resistance that each ppo mutant endows weed populations not yet understood. We aimed evaluate response of PPO-resistant accessions, harboring ppo2 mutations ?G210 and G399A, multiple PP...
