But levels increased when the plants encountered drought or salt stress, he said. Manually increasing the level of the lncRNA showed corresponding increases in drought and salt tolerance compared with plants where the lncRNA level was unaltered.\n<\/div>\n<div>Most RNA direct or \u201ccode\u201d cell machinery to produce proteins. Non-coding RNA, or ncRNA, does not direct protein production but could affect how gene expressions manifest in innumerable other ways. As such, they are considered regulators of important biological processes, Xiong said.\n<\/div>\n<div>\u201cAnd there are different types of ncRNA,\u201d he said. \u201cSmall ncRNA have received much attention in recent years, but in many long, or lncRNA, like the one we found to affect drought and salt tolerance in thale cress, the biological functions remain unknown.\u201d\n<\/div>\n<div>The basic difference between small and long non-coding RNA is the number of nucleotides \u2014 the structural building blocks of RNA. Long have more.\n<\/div>\n<div>Xiong said investigating the effects of lncRNA is a novel approach to plant drought and salt tolerance research.\n<\/div>\n<div>\u201cMost of the current work on improving plant stress tolerance does not focus on lncRNA but on the genes that code protein production,\u201d he said. \u201cHowever, manipulation of those protein-encoding genes often impairs plant growth and development.\u201d\n<\/div>\n<div>But the lncRNA studied by Xiong\u2019s team can be tweaked without any apparent detriment to the plant\u2019s health, he said.\n<\/div>\n<div>\u201cIt\u2019s early still, but we could be on the brink of a whole new approach to engineering drought and salt tolerance in plants, including food plants,\u201d Xiong said. \u201cOur next step will be to engineer the lncRNA levels in plants other than thale cress and to test whether it might improve drought and salt tolerance across a broader spectrum.\u201d<\/div>\n<\/div>\n<div><\/div>\n<\/div>\n<div class=\"post-meta\"><b>Source:\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<\/b>Texas A&amp;M AgriLife Research<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Keywords: RNA, heat, drought tolerance Texas A&amp;M AgriLife Research scientists have discovered a ribonucleic acid, or RNA.
