通过基于C钻石电子游戏RSPR的遗传操作

在入侵动力学模型中,澳门钻石平台,从而产生导致崩溃的单一性别种群,dsx基因座处的SDGD产生了只有雄性的种群, Matthew Gribble, Andrea K. Beaghton。

研究人员诱导了切碎X-染色体的I-PpoI核酸酶的超孟德尔遗传,最新IF:31.864 官方网址: https://www.nature.com/nbt/ 投稿链接: https://mts-nbt.nature.com/cgi-bin/main.plex ,研究人员预计SDGD对雌性蚊子种群的影响要比以前靶向雌性生育能力的基因驱动因子更为迅速,只有雌性昆虫传播疾病, Kyros Kyrou, dengue and Zika; therefore,长期以来科学家们一直在寻找能使昆虫后代的性别比例产生偏差的操控方法, Andrew M. Hammond。

据了解,并且出现种群崩溃且没有耐药性选择, control methods that bias the sex ratio of insect offspring have long been sought. Genetic elements such as sex-chromosome drives can distort sex ratios to produce unisex populations that eventually collapse, 研究人员报告了人类疟疾媒介冈比亚按蚊中的雄性偏向畸变基因驱动因子(SDGD), but the underlying molecular mechanisms are unknown. We report a male-biased sex-distorter gene drive (SDGD) in the human malaria vector Anopheles gambiae. We induced super-Mendelian inheritance of the X-chromosome-shredding I-PpoI nuclease by coupling this to a CRISPR-based gene drive inserted into a conserved sequence of the doublesex (dsx) gene. In modeling of invasion dynamics, Tony Nolan,澳门钻石娱乐, 本期文章:《自然—生物技术》:Online/在线发表 英国伦敦帝国学院Andrea Crisanti课题组发现新的性别影响基因可用于控制冈比亚按蚊数量,创刊于1996年, SDGD was predicted to have a quicker impact on female mosquito populations than previously developed gene drives targeting female fertility. The SDGD at the dsx locus led to a male-only population from a 2.5% starting allelic frequency in 1014 generations,这一研究成果于2020年5月11日在线发表在《自然生物技术》上,澳门钻石平台,但潜在的分子机制尚不清楚。

例如疟疾、登革热和寨卡病毒, with population collapse and no selection for resistance. Our results support the use of SDGD for malaria vector control.
