Thie study aimed at comparing polymorphisms in exons of the IGFBP-1 gene encoding insulinlike growth factor binding protein-1 among three chicken breeds and analysing the associations between its genotypes and body weight traits in the Jinghai Yellow chicken. Three mutations (A2276T, T2359C and T5550C) and one insertion/deletion (the inserted/deleted AAT after position 5692bp) were detected in three chicken breeds. The general linear model analysis showed that the Jinghai Yellow chickens with BB and AB genotypes at the position 2276 (A2276T transversion) had significantly higher body weight than those of AA genotype (P<0.05 or P<0.01) at week 4, 8, and 16 of age. Moreover, BB genotype had significantly higher body weight at week 12 of age than those of AB genotype (P<0.01). The B allele had a positive effect on body weight traits.

Low light is one of the most important factors affecting cucumber growth in winter solar greenhouses in northern China. Whether induction light intensity has an effect on expressions of rbcL, rbcS and rca genes in cucumber leaves grown under low light for long periods of time remains unclear. Here, two genotypes of cucumber were used to determine the effects of growth and induction light levels on photosynthetic induction. It was found that regardless of growth and induction light intensity, the transcript levels of rbcL, rbcS and rca increased quickly once the plant was exposed to light. The variations of the photosynthesis (PN), stomatal conductance (gₛ), actual photosystem II efficiency (ΦPS II) and Rubisco activity were similar to transcript levels. Plants grown at a photon flux density (PFD) of 100 µmol m⁻² s⁻¹ had lower PN, and initial and total Rubisco activity than those grown at 600 µmol m⁻² s⁻¹ , regardless of induction PFD; for plants grown at the same PFD, PN, gₛ and Rubisco activation rate induced under PFD of 100 µmol m⁻² s⁻¹ were lower than those under 600 µmol m⁻² s⁻¹ . Rubisco, especially RCA, played a great role on photosynthesis during photosynthetic induction. Compared with Jinyan No. 2, Deltastar may possess potential low-light tolerance with a lower decrease of PN, and initial and total Rubisco activities when grown and induced at 100 µmol m⁻² s⁻¹ than 600 µmol m⁻² s⁻¹ . Moreover, the mechanism of Rubisco activase in regulating Rubisco during photosynthetic induction is also discussed.

Oxytropis ochrocephala Bunge is a poisonous legume plant which exhibits drought acclimation behavior and spreads rapidly under adverse environment. This study demonstrates that the stress signals including NO (nitric oxide), ABA (abscisic acid), and H2O2 (Hydrogen peroxide) are involved in roots of O. ochrocephala seedlings when exposed to drought stress simulated by PEG-6000 solution. The relationship among these signals was investigated by using exogenous and endogenous modulators. The results indicate that a time course of NO is accumulated in roots of O. ochrocephala in response to drought stress, which is generated enzymatically by nitrate reductase (NR) activity. The low level of NO acts as a downstream signaling of ABA and is involved with H2O2 signaling cascade. There is a regulatory mechanism of controlling NO concentration and maintaining the equilibrium state between ROS (reactive oxygen species) and NO, which modulates the root cell vitality, and osmotic adjustment thus improves root growth and developmental processes under drought stress.

Performance of ozone/persulfate-UBAF used for advanced treatment of physically treated effluent from herbal decoction pieces of wastewater was investigated in a pilot scale experiment. Under optimum conditions – i.e., an initial pH, temperature 13-27ºC, 30 min of oxidation, 35 mg/L O₃ dosage, S₂ O₈²⁻ /COD (g/g) ratio (0.15), gas/liquid ratio in UBAF (3), hydraulic retention time in UBAF (5h)– the COD and NH₃ -N removal efficiencies were 87.54-89.53% and 82.94-86.77%, respectively. Under optimum conditions, ozone/persulfate oxidation lowered pH values by about 0.1 pH units (average value), presented lower OCC (from 0.14 to 0.16 kg O₃ /kg COD removed), and significantly improved the wastewater biodegradability from 0.16 to 0.55 (average value). Compared with O₃ /H₂ O₂ oxidation, the ozone/persulfate system achieved a better enhancement effect in wastewater treatment (i.e., decreased 24.0% OCC and saved 11.4% in operational costs). Furthermore, the COD removal rate in ozone/persulfate oxidation stage followed the first order ln(C/C₀)=- 0.0167t , and the COD concentration in UBAF effluent was expressed by the model C/C₀=exp(-0.2940/-L⁰‧⁰⁹¹² H) at various hydraulic loading ratesfor maintenance and selection of UBAF. Finally, the study proved that the combined process was an efficient technology in treating physically treated effluent from herbal decoction pieces wastewater.
