Its production is seriously affected by several factors, specifically stresses such as declining soil fertility, narrow genetic diversity in germplasm, and inadequate availability of clean planting material among smallholder farmers. Diseases and pests are a major factor limiting yields worldwide. Production is mainly reduced by many bacterial, fungal, and viral pathogens, mainly\u00a0<em>Xanthomonas campestris<\/em>\u00a0pv.\u00a0<em>musacearum<\/em>\u00a0(Xcm) causing banana Xanthomonas wilt (BXW),\u00a0<em>Ralstonia solanacearum<\/em>\u00a0causing moko and bugtok disease,\u00a0<em>Ralstonia<\/em>\u00a0<em>syzygii<\/em>\u00a0subsp.\u00a0<em>celebesensis<\/em>\u00a0causing blood disease,\u00a0<em>Pseudocercospora fijiensis,<\/em>\u00a0<em>P. musae,\u00a0<\/em>et\u00a0<em>P. eumusae<\/em>\u00a0causing black Sigatoka, yellow Sigatoka, and leaf spot disease, respectively,<em>\u00a0Fusarium oxysporum\u00a0<\/em>f. sp.\u00a0<em>cubense<\/em>\u00a0causing fusarium wilt (commonly known as panama disease), and viruses such as\u00a0<em>banana bunchy top virus\u00a0<\/em>(BBTV) and\u00a0<em>banana streak virus\u00a0<\/em>(BSV), and pests like nematodes and weevils.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There is a huge yield gap in banana production in areas where several of these pathogens and pests occur together. Therefore, improved varieties need to be developed with multiple and durable resistance to pathogens and pests. Modern breeding tools such as genome editing can be applied to improve banana, complementing traditional breeding. CRISPR\/Cas9 has emerged as a potent editing tool that can be used ef\ufb01ciently to induce targeted mutations in the genomes of plant species to produce improved varieties. This technology has been successfully applied in many organisms including several plant species.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"http:\/\/annualreport18.iita.org\/2020\/04\/20\/application-of-genome-editing-for-improving-banana-2\/\" target=\"_blank\" rel=\"noopener noreferrer\">Lire la suite<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>Banana is a major staple food crop feeding more than 500 million people in tropical and subtropical countries.
