Objective: The study was conducted to evaluate the effects of different methionine (Met) sources on production performance, reproduction performance, egg quality and serum biochemical indices in broiler breeders. Methods: After receiving a basal diet (containing 0.25% Met) for a 2-wk pretreatment period, a total of 360 39-wk-old Lingnan yellow broiler breeders were randomly allocated to four treatments with six replicates each (15 birds per replicate). Breeders were fed with basal diets (control) or diets supplemented with DL-methionine (DLM), DL-2-hydroxy-4-methylthio butytric calcium (MHA-Ca) and coated DL-Met (CME) respectively. Results: The results showed that CME supplementation promoted laying rate and decreased feed-to-egg ratio (F/E) (p<0.05), DLM and MHA-Ca supplementation decreased F/E (p<0.05) when compared with control group. The rate of fertility, hatchability and birthrate were higher (p<0.05) in DLM, MHA-Ca, and CME groups than control group. Compared with control group, CME increased the eggshell thickness (p<0.05); MHA-Ca improved the eggshell thickness, shell ratio and eggshell strength (p<0.05). Results also showed that CME elevated the concentration of total protein in serum (p<0.05); MHA-Ca improved the concentration of calcium in serum (p<0.05). The concentration of serum uric acid in DLM, MHA-Ca, and CME groups was lower than that in control group (p<0.05). Besides, CME had higher concentrations of serum taurine, cysteine and cystanthionine (p<0.05) while MHA-Ca and DLM promoted the serum taurine concentration (p<0.05) compared with control group. Conclusion: Based on the results, it was concluded that Met supplementation could enhance the production and reproduction performance as well as the antioxidant status and egg quality of broiler breeders. In terms of improving the production performance, reproduction performance and antioxidant performance, CME was superior to DLM and MHA-Ca; but in regard to the enhancement of eggshell quality and serum Ca concentration, MHA-Ca was superior to DLM and CME.

A Novel Pepper (Capsicum annuum L.) WRKY Gene, CaWRKY30, Is Involved in Pathogen Stress Responses
Zheng Jingyuan,Zou Xuexiao,Mao Zhenchuan,Xie Bingyan 한국식물학회 2011 Journal of Plant Biology Vol.54 No.5
WRKY proteins are a superfamily of transcription factors involved in many plant processes including plant defense responses to biotic and abiotic stresses. We isolated a WRKY gene from pepper during the incompatible interaction between the pepper cultivar HDA149 and Meloidogyne incognita. The full-length gene, named as CaWRKY30, has a 1,533-bp cDNA sequence and contains an open reading frame of 1,095 bp, encodes a putative polypeptide of 364 amino acids with a theoretical protein size of 41.2 kDa, and contains one WRKY domain followed by a zinc-finger motif. The genomic sequence of CaWRKY30 contains three exons and two introns. Southern blot analysis confirmed that CaWRKY30 exists as a single copy in the pepper cultivar HDA149 genome. Quantitative RT-PCR showed that CaWRKY30 is up-regulated by application of various pathogens including avirulent M. incognita, Tobacco mosaic virus, Ralstonia solanacerum,and Phytophthora capsici Leonian. Furthermore, the transcripts of CaWRKY30 were rapidly induced after treatment with phytohormones salicylic acid (SA). However, the expression of CaWRKY30 was down-regulated by virulent M. incognita and phytohormones methyl jasmonic acid (MeJA). In addition, the nuclear localization of CaWRKY30 was determined when a CaMV35s::CaWRKY30-eGFP fusion construct was expressed in onion epidermal cells. These results suggested that CaWRKY30might be involved in plant defense mechanisms against the diverse pathogen infection.
