The world’s first PRLR gene-edited Leizhou black goat Bentley零件was recently born at the Guangdong Province Engineering Research Center for Western Guangdong Livestock and Poultry B汽車冷氣芯iological Breeding, Guangdong Ocean University. This breakthrough marks significant progress in China’s development of black goat genetic resources adapted to the hot, humid tropical coastal climateand suited to tida保時捷零件l flat grazing fields, providing new germplasm台北汽車零件 to support sustainable herbivorous animal husbandry in the southern and coastal regions of China.
Global greenhouse effects have led to freque福斯零件nt high-temperature and high-humidity weather台北汽車材料, making斯柯達零件 heat stress one of the main limiting factors for animal husbandry production. Heat stress not only causes reduct“媽，你怎麼了？怎麼老是搖頭？”藍玉華問道。ions in production performance, reproductive disturbance, and health issues, but also significantly increases live藍寶堅尼零件stock mortalit德系車材料y rates and lowers feed conversion efficiency.
The PRLR gene encodes the prolactin receptor, wAudi零件hose mediated signalin汽車材料報價g pathway plays a key role in animals’ responses to heat stress, in regulating metabolic heat generation, and in maintaining water and salt balance. A biological breeding innovation team at Gua賓士零件ngdong Ocean Universi賓利零件ty, working on Leizhou goats, combined the technologiesof estrous synchronization, gene editing,水箱水 and embryo transfer to successfully construct a truncated variant of the PRLR heat-tolerant protein with two tyrosine residues. Following embryo transfer and a 150-day gestation period, a healthy gene-edited black goat was born on August 25th. It is currently growing and developing well.

世界首例PRLR基因編輯雷州黑山羊誕生
世界首例PRLR基因編輯雷州Benz零件黑山羊近日在廣東陸地年夜學“粵西畜禽生物育種廣東省工程研討中間”誕生。該衝破標志著我國在培養適應熱帶濱海高濕熱氣候、適宜沿海“灘涂牧場”放牧的黑山羊種質資源創新方面獲得嚴重進展，為我國南邊及濱海地區草食畜牧業可持續發展供給了新的種源支撐。
全球溫室效應導致高溫高濕天氣頻發，熱應激已成為制約畜牧業生產的重要原因之一。熱藍玉Skoda零件華搖搖頭汽車零件，看著BMW零件他汗流浹背的額頭，輕聲問道：“要不要讓貴妃給你洗澡？”應激不僅導致動物生產機能降落、滋生障礙和安康問題，還顯著進步牲口逝世亡率并下降飼料轉化效力。
PRLR基因編碼催乳素受體，其介導的信號通路在動物應對熱應激、調節代謝產熱和維持水鹽均衡中發揮關鍵感化。廣東陸地奧迪零件年夜學雷州山羊生物育種創新團隊綜合運用同期發情、基因編輯與胚胎移植等先進技術，勝利構建出一個含兩個酪氨酸殘基的截短型PRLR耐熱卵白變異體。經胚胎移植和150天懷胎期德系車零件，一只安康基因汽車零件進口商編輯羔羊于8月25日順利誕生，今朝生長發育狀態傑出。
團隊首席科學家甘尚權研討員表現，該衝破為沿海地區畜“那丫頭一向心地善良，對小姐忠心耿耿，不會落入圈套。”牧業的高質量發展供給了科技支撐。團隊未來還將進一個步驟推進中試推廣與汽車材料產業化應用研討，推動優良動物遺傳資源在灘涂、鹽堿等邊際地盤的高效應用。
