Published in the <em>American Journal of Botany<\/em> in March 2010, their research began with a plant called the \u201cresurrection fern\u201d (<em>Polypodium polypodioides<\/em>) which can lose 95% of its water content without experiencing cell death.\u00a0 One of the main scientists from Villanova explains that this is truly a miraculous property.\u00a0 He says, \u201cImagine this happening to a human.\u00a0 Most of us wouldn\u2019t make it past <img loading=\"lazy\" decoding=\"async\" class=\"alignleft\" style=\"border: 1px solid black;margin-top: 1px;margin-bottom: 1px\" title=\"Resurrection Fern\" src=\"http:\/\/www.fernridgefarms.com\/images\/ResurrectionFern.jpg\" alt=\"\" width=\"389\" height=\"292\" \/>10% or 20%.\u201d\u00a0 Similarly, most common agricultural crops cannot survive water loss of 20-30%.<\/p>\n<p>They used research techniques such as <a href=\"http:\/\/en.wikipedia.org\/wiki\/Western_blot\" target=\"_blank\">western blotting<\/a>, immunolocalization, and atomic force microscopy to identify proteins that help the resurrection fern survive in extreme drought condition.<\/p>\n<p>A class of proteins called dehydrin has been previously identified to participate in this miraculous drought resistance.\u00a0 However, this study was able to identify the location of dehydrin proteins during the process of dehydration.\u00a0 They found that the proteins were \u201cprevalent\u201d in the plant\u2019s cell wall.\u00a0 This is an important discovery that may lead to new findings about the mechanism of this reaction.<\/p>\n<p>Information about this protein class has positive implications for common agricultural plants that currently don\u2019t have protection against drought.\u00a0 Dehydrins, and the mechanism of their role in drought resistance, could be the answer for thirsty plants worldwide as research continues.<\/p>\n<p>Want to learn more?
