They are eukaryotic organisms; i.e., their cells contain membrane-bound organelles and clearly defined nuclei. Fungi usually reproduce both sexually and asexually. Fungi are either terrestrial or aquatic, the latter living in freshwater or marine environments. They are found in all temperate and tropical regions of the world where there is sufficient moisture to enable them to grow.<\/p>\n<p><strong>Source: <\/strong><a href=\"https:\/\/www.hindustantimes.com\/cities\/chandigarh-news\/cpri-issues-advisory-as-late-blight-disease-threatens-potato-crops-101720823388794.html\" target=\"_blank\" rel=\"nofollow noopener\">CPRI issues advisory as late blight disease threatens potato crops<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Late blight (Phytophthora infestans) is one of the most serious fungal diseases that can affect tomatoes and potatoes.<\/p>\n","protected":false},"author":5,"featured_media":18395,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[],"class_list":{"0":"post-18394","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-upsc-prelims-current-affairs","8":"no-featured-image-padding"},"acf":[],"_links":{"self":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/18394","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/comments?post=18394"}],"version-history":[{"count":0,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/18394\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media\/18395"}],"wp:attachment":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media?parent=18394"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/categories?post=18394"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/tags?post=18394"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
