The 158th Notice of AgriX Forum | Research, Development and Application of Haploid Breeding Technology
The last Baibo Wisdom Lecture Hall invited Dr. Fu Peng of Harrisburg University to share the content of "Research on High throughput Photosynthetic Phenotypes of Crops Based on Near surface Remote Sensing". The lecture was very exciting. Welcome to watch the replay.
This is the 158th issue of Baibo Wisdom Lecture Hall (July 30). Dr. Liu Chenxu from China Agricultural University was invited to share the content of "haploid breeding technology research and development and application". Welcome to this lecture!
China Agricultural University——Dr. Liu Chenxu
The 158th Lecture
Liu Chenxu is an associate professor of China Agricultural University.
Education experience: 2007-2011 Shandong Agricultural University Agricultural College Undergraduate 2011-2017 China Agricultural University Agricultural College Doctoral work experience: 2017-2018 China Agricultural University Postdoctoral
2018-2020 Post doctoral of New Jersey State University, USA 2020 Present Associate Professor of Agricultural College of China Agricultural University
Mainly engaged in the research of maize haploid breeding technology and theory, carried out work in the genetic and biological mechanism of haploid induction, breeding of new haploid induction lines and wheat haploid breeding, cloned the key gene ZmPLA1 for maize haploid induction, developed high oil haploid induction lines CHOI4 and CHOI5, and achieved haploid seed induction on wheat. More than 10 papers have been published in Nature Plants, Molecular Plant, Plant Biotechnology Journal, The Plant Journal, TAG and other journals in a single work or communication, and more than 10 haploid breeding related patents have been approved. He won the Excellent Doctoral Thesis Award of the Crop Society, the Dabei Agricultural Plant Breeding Award, etc.
Targeted sequencing is a method to isolate, enrich and sequence a group of target genes or genome regions. This method enables researchers to focus time, cost and data analysis on specific regions of interest (target regions, genes), and use less data to obtain higher sensitivity and accuracy, so as to achieve rapid screening of mutation sites. These target regions usually include exome (the protein coding part of the genome), specific genes of interest (customized content), and target regions in genes or mitochondrial DNA.
FBI seq (Foreground and Background Integrated genotyping by sequencing) is not sequencing by the US Federal Bureau of Investigation, but genotyping sequencing integrating foreground and background. As the name implies, this technology realizes the detection and selection of foreground genes and genetic background at the same time. The selection of foreground and background is two very important steps in molecular breeding. At present, breeders often need to carry out these two steps independently: first, screen foreground target sites, and then develop a large number of probes/bait/PCR primers to detect background genotypes. These time-consuming and costly preparations greatly delay the start of breeding projects.
Deeply cultivate the agricultural core, and work together for the future. In response to the call of the country to build a "China core" of seed industry, and to promote the joint construction of the "Northern Seed City", Phoenix Expo was officially upgraded to the "China Northern Seed Expo" on the basis of successfully holding three sessions of China Shandong International Vegetable Seed Expo, focusing on new varieties and new technologies such as field, vegetables, fruits and vegetables, horticulture, balcony agriculture, and combining cloud seed industry, cloud plant protection, cloud agricultural science platform, Build online and offline promotion and trading dual platforms for seed breeding. The 2022 Northern Species Expo will be linked with the 29th Shandong Double Trade Fair for Plant Protection, China Shandong International New Fertilizer Exhibition, and China (Shandong) New Agricultural Equipment Exhibition!
