A single chromosome of the grass species Festuca pratensis has been introgressed into Lolium perenne to produce a diploid monosomic substitution line 2n = 2x = 14. In this line recombination occurs throughout the length of the F. pratensis/L. perenne bivalent. The F. pratensis chromosome and recombinants between it and its L. perenne homeologue can be visualized using genomic in situ hybridizat...

After 11 hours, male chicks (5 days old) injected intraperitoneally with 2 units of insulin, became hypoglycemic (2.51 f 0.48 mu uersus 14.42 f 0.35 m&r) and occasionally convulsed. The whole brain glucose, glucose 6-phosphate, fructose 1,6-diphosphate, and lactate levels were diminished, respectively, from 1.60 f 0.18 to 0.24 f 0.04 mrd, from 0.044 f 0.002 to 0.016 f 0.002 mM, from 0.139 f 0.0...

lead (pb) is one of the most hazardous heavy metal that caused serious problems for ecosystem at recent years. in this study, the effect of pb on seed germination, incipient growth and antioxidant enzymes of six common used turfgrasses was investigated. the results showed that after implementation of different concentrations (0, 1000, 2000 and 3000 µm) of pb, agropyron elongatum exhibited the h...

It has been suggested that sexual identity in the germline depends upon the combination of a nonautonomous somatic signaling pathway and an autonomous X chromosome counting system. In the studies reported here, we have examined the role of the sexual differentiation genes transformer (tra) and doublesex (dsx) in regulating the activity of the somatic signaling pathway. We asked whether ectopic ...

stats are a family of latent transcription factors that reside in the cytoplasm of resting cells. the stat1 transcription factor gene located on the chromosome 2 at interval 60 to 63 cm. this factor upon stimulation with inf gamma, dimerizes and translocate to the nucleus where mediates transcriptional regulation. in this study, we estimated the allele and genotype frequencies of stat1/pag1 gen...

The aim of this study was to identify genomic regions underlying milk production traits in the Valle del Belice dairy sheep using regional heritability mapping (RHM). Repeated measurements for yield (MY), fat percentage and (F% FY) protein (P% PY), collected over a period 6 years (2006–2012) on 481 ewes, were used analysis. Animals genotyped with Illumina 50k SNP chip. Variance components, heri...
