Abstract Background As a biennial plant, Secale cereale L is usually harvested in the autumn northern part of China where temperature difference between day and night great disparity Through pot experiment, seedlings were cut to 2, 6 10 cm stubble height, simulated freeze-thaw (FT) stress (10/− 5 °C) was carried out after days regrowth. The physiological effects FT with different height reveale...

in this research, the effect of water stress on the soluble sugars, starch and proteins content of two different cultivars (kaka and jam) of chickpea (cicer arietinum) was studied. the results showed that the soluble sugars increased while starch decreased during the stress in shoot and root of both cultivars. increasing of soluble sugars and decreasing of starch hall a positive correlation wit...

The silage quality and bacterial community of hybrid Pennisetum (P. hydridum × P. americanum) with or without 30% 50% mulberry leaves for 3, 7, 14, 30 days were investigated. Results showed that compared the 100% group, more lactic acid (40.71 vs. 80.81 g/kg dry matter (DM)), acetic (10.99 31.84 DM), bacteria (8.46 8.51 log10 cfu/g fresh matter), water-soluble carbohydrates (2.41 4.41 g/100 g c...

objective: the aim of this experiment was to determine chemical composition, protein quality of corn gluten meal (cgm) and its effect on growth performance of broiler chicks. methods: chemical composition and nitrogen corrected true metabolizable energy of cgm was determined by standard and precision-fed cockerel assay methods.  for evaluating of protein quality, 90 male broiler chicks in a com...

Homeobox genes encode transcription factors which play important roles in the developmental processes of many multicellular organisms. TGIFLX/Y (TGIFLX and TGIFLY) are members of the homeobox superfamily of genes. Their expressions are specifically detected in the human adult testis but their functions are remained to be investigated. In this investigation we cloned full length of TGIFLY cDNA a...

Crude protein (CP) of forages can be separated into fractions of differentiated abilities to provide available amino acids in the lower gut of ruminants. This knowledge is critical to develop feeding systems and to predict animal responses. We have measured during two growing seasons (1996 to 1997 and 1997 to 1998) the CP fractions of common vetch fresh forage with the objective being to assess...

background: as a drug target and an antigenic agent, hiv-1 protease (hiv-1 pr) is at the center of attention for designing anti-aids inhibitors and diagnostic tests. in previous studies, the production of the recombinant protease has been faced with several difficulties; therefore, the aims of this study were the easy production, purification of the soluble form of protease in e. coli and inves...
