“果蔬杀手”有了完整的基因组图谱

Core Viewpoint - The research focuses on decoding the genetic blueprint of the fruit fly pest, Bactrocera dorsalis, to develop new green pest control methods as traditional pesticides become less effective [1][2]. Group 1: Research Findings - The research team successfully constructed the most complete genomic map of the highly heterozygous pest, Bactrocera dorsalis, which is crucial for identifying potential targets for green pesticides [1][4]. - Previous genomic versions of Bactrocera dorsalis were based on mixed individuals, leading to significant gaps in the genome, particularly in repetitive DNA regions [2][3]. - The new assembly strategy utilized sequencing data from individual male flies, resulting in a nearly complete genome of approximately 600Mb, including the Y chromosome [3][4]. Group 2: Implications for Pest Control - The high-resolution genomic map revealed that the centromere region consists of three different types of satellite DNA, and identified a gene on the Y chromosome related to the energy demands of male flies [4]. - The discovery of new olfactory receptor genes and Y chromosome-specific genes provides valuable targets for the development and optimization of green pest control technologies [4].
