Effective and sustainable management of this disease necessitates a thorough understanding of the genetic diversity of the pathogen. This study aimed to characterize the genetic diversity of Phytophthora colocasiae through morphological and molecular analyses of isolates collected from multiple locations. A total of 44 isolates were evaluated using four morphological markers and nine molecular markers. Morphological assessment identified six distinct morphotypes based on colony growth characteristics, with isolates further categorized into three growth-rate classes. Molecular characterization revealed low genetic diversity within the pathogen population, as indicated by a Shannon diversity index of 0.4. Analysis of molecular variance (AMOVA) showed that genetic variation was predominantly distributed within populations, with minimal differentiation and low genetic distances between groups. These findings offer<br \/>\nessential insights into the population structure of Phytophthora colocasiae and provide a foundation for the development of targeted management strategies to mitigate taro leaf blight in Burkina Faso.<\/p>\n<\/section>\n<section>\n<h2 class=\"sub-title\">Mots-cl\u00e9s<\/h2>\n<p>Phytophthora colocasiae, Genetic diversity, Taro leaf blight, Molecular analysis, Burkina Faso<\/p>\n<\/section>\n","protected":false},"excerpt":{"rendered":"<p>Ann\u00e9e\u00a0: 2025 Revue\u00a0: International Journal of Biosciences\u00a0, Vol.27 (3) :\u00a076-87 Lien de l&rsquo;article :\u00a0\u00a0https:\/\/dx.doi.org\/10.12692\/ijb\/27.3.76-87 Discipline :\u00a0Sciences biologiques Auteur(s) :\u00a0C\u00e9c\u00e9 Marie Claire, Traor\u00e9 Renan Ernest, Sogoba Kouka Hamidou, Ouedraogo Nicolas Auteur(s) tagu\u00e9s :\u00a0TRAORE Renan Ernest R\u00e9sum\u00e9 Taro leaf blight, caused by the oomycete Phytophthora colocasiae, represents a significant constraint to taro production in the Sudanian climatic [&hellip;]<\/p>\n","protected":false},"author":46,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[18],"tags":[261,259,262,184],"class_list":["post-1088","post","type-post","status-publish","format-standard","hentry","category-articles-scientifiques","tag-cece-marie-claire","tag-ouedraogo-nicolas","tag-sogoba-kouka-hamidou","tag-traore-renan-ernest"],"_links":{"self":[{"href":"https:\/\/www.gril-ujkz.com\/index.php\/wp-json\/wp\/v2\/posts\/1088","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.gril-ujkz.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.gril-ujkz.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.gril-ujkz.com\/index.php\/wp-json\/wp\/v2\/users\/46"}],"replies":[{"embeddable":true,"href":"https:\/\/www.gril-ujkz.com\/index.php\/wp-json\/wp\/v2\/comments?post=1088"}],"version-history":[{"count":1,"href":"https:\/\/www.gril-ujkz.com\/index.php\/wp-json\/wp\/v2\/posts\/1088\/revisions"}],"predecessor-version":[{"id":1089,"href":"https:\/\/www.gril-ujkz.com\/index.php\/wp-json\/wp\/v2\/posts\/1088\/revisions\/1089"}],"wp:attachment":[{"href":"https:\/\/www.gril-ujkz.com\/index.php\/wp-json\/wp\/v2\/media?parent=1088"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.gril-ujkz.com\/index.php\/wp-json\/wp\/v2\/categories?post=1088"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.gril-ujkz.com\/index.php\/wp-json\/wp\/v2\/tags?post=1088"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
