Such plants regain normal function after rehydration. Desiccation tolerance is a common phenomenon in lichens, mosses, and ferns. However, it is rare in the vegetative tissues of angiosperm species. <em>Paraboea rufescens<\/em> (Gesneriaceae) is widely distributed in the karst habitats of southwest China. In the dry season, leaves of <em>P. rufescens<\/em> curl severely and turn their abaxial side outward; however, they unfold and recover completely in the rainy season or after a rain in the dry season. The mechanism for whole plant recovery from severe dehydration is still not clear, especially for woody resurrection plants. In this seminar, I will give an introduction about how leaf gas exchange and water relations of <em>P. rufescens<\/em> response during dehydration and following rehydration process. The root pressure was also monitored for well watered and the severely dehydration individuals after rehydration. The results showed that leaf water status and leaf hydraulic conductance quickly recovered to well-watered levels after rehydration, while leaf gas exchange also trended to recovery, but at a slower rate. The maximum root pressure in rehydrated <em>P. rufescens<\/em> was more than twice in well-watered plants. In this seminar, I will also compare leaf gas exchange, wood anatomy, hydraulic conductivity and desiccation tolerance between <em>P. rufescens <\/em>and other two <em>Paraboea<\/em> species.<\/p>\n\n\n\n<hr class=\"wp-block-separator is-style-wide\"\/>\n\n\n<p><strong>Speaker:<\/strong> Dr. Peili Fu<\/p>\n<p><strong>Affiliation: <\/strong>XTBG<\/p>\n<p><strong>Time:<\/strong> 4:30 PM, Tuesday, Sep. 27 2022<\/p>\n<p><strong>Venue: <\/strong>ZOOM \u4f1a\u8bae\u5e73\u53f0 \u4f1a\u8bae ID\uff1a312 430 8960 \u4f1a\u8bae\u5bc6\u7801 PWD\uff1a666666\u00a0<\/p>\n<p>ZOOM<br \/>\u4f1a\u8bae ID\uff1a312 430 8960<br \/>\u4f1a\u8bae\u5bc6\u7801 PWD\uff1a666666<\/p>\n\n\n<hr class=\"wp-block-separator is-style-wide\"\/>\n\n\n\n<div class=\"wp-container-1 wp-block-group\"><div class=\"wp-block-group__inner-container\">\n<div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<\/div><\/div>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Speaker: Dr. Peili Fu<br \/>\nAffiliation: XTBG<br \/>\nTime: 4:30 PM, Tuesday, Sep. 27 2022<\/p>\n","protected":false},"author":2,"featured_media":3091,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[3],"tags":[],"_links":{"self":[{"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=\/wp\/v2\/posts\/3090"}],"collection":[{"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=3090"}],"version-history":[{"count":1,"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=\/wp\/v2\/posts\/3090\/revisions"}],"predecessor-version":[{"id":3092,"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=\/wp\/v2\/posts\/3090\/revisions\/3092"}],"wp:featuredmedia":[{"embeddable":true,"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=\/wp\/v2\/media\/3091"}],"wp:attachment":[{"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=3090"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=3090"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=3090"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
