10.  Diversity in conduit and pit structure among extant gymnosperm taxa.LinkIT
Jacobsen AL
American journal of botanyAm J BotDiversity in conduit and pit structure among extant gymnosperm taxa.559-57010.1002/ajb2.1641Gymnosperm taxa are incredibly diverse in many traits, including taxa with evergreen or deciduous leaves; broad, compound, needle-like or scale-like leaves; trees, shrubs, and lianas; and taxa with seed cones that range from fleshy to woody. Although less appreciated, xylem conduits are also diverse in structure among extant gymnosperm taxa. Within the xylem of gymnosperms, axial transport occurs predominantly via tracheids, although 10-40% of gymnosperm taxa, particularly within the Gnetophyta and Cycadophyta, also contain vessels. Gymnosperm taxa vary greatly in their inter-conduit pit structure, with different types of pit membranes and pitting arrangements. While some taxa display torus-margo bordered pits (60%), many others do not contain tori (40%), and at least some taxa without tori occur within each of the four extant phyla (Coniferophyta, Cycadophyta, Ginkgophyta, and Gnetophyta). Pit membrane types vary within families but appear relatively conserved within genera. Woody species with torus-bearing pit membranes occur in colder environments (lower mean annual temperature) compared to those without tori; but occurrence does not differ with mean annual precipitation. Detailed descriptions of pit membrane types are lacking for many species and genera, indicating a need for increased anatomical study. Increased knowledge of these traits could provide a unique experimental context in which to study the evolution of conduit networks, the hydraulic implications of conduit and pit structure, and the diverse structural and functional strategies utilized by gymnosperms. There are myriad potential study questions and research opportunities within this unique and diverse group of plants.© 2021 Botanical Society of America.JacobsenAnna LAL0000-0001-7830-5590Department of Biology, California State University, 9001 Stockdale Hwy, Bakersfield, CA, 93311, USA.engJournal ArticleResearch Support, U.S. Gov't, Non-P.H.S.Review20210416United StatesAm J Bot03704670002-9122059QF0KO0RWaterIMCycadopsidageneticsTracheophytaTreesWaterXylembordered pitmargopit membranepittingseriationtorustracheary elementstracheidvesselxylem202009152020120420214176020215256020214161721ppublish3386186610.1002/ajb2.1641LITERATURE CITED, 2021</i></font><br><font color=#008000>http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=0<br></font></span><br><br><br><table cellspacing=0 cellpadding=0 align=center><tr valign=bottom><td align=center><img src=p.png border=0></td><td align=center><img src=o_red.png border=0></td><td align=center><a href=http://ubio.org/portal/index.php?search=Cycadopsida+Brongn.+class.&category=l&client=pubmed&startPage=2><img src=o_yellow.png border=0></a></td><td align=center><a href=http://ubio.org/portal/index.php?search=Cycadopsida+Brongn.+class.&category=l&client=pubmed&startPage=3><img src=o_yellow.png border=0></a></td><td align=center><a href=http://ubio.org/portal/index.php?search=Cycadopsida+Brongn.+class.&category=l&client=pubmed&startPage=4><img src=o_yellow.png border=0></a></td><td align=center><a href=http://ubio.org/portal/index.php?search=Cycadopsida+Brongn.+class.&category=l&client=pubmed&startPage=5><img src=o_yellow.png border=0></a></td><td align=center><a href=http://ubio.org/portal/index.php?search=Cycadopsida+Brongn.+class.&category=l&client=pubmed&startPage=6><img src=o_yellow.png border=0></a></td><td align=center><a href=http://ubio.org/portal/index.php?search=Cycadopsida+Brongn.+class.&category=l&client=pubmed&startPage=7><img src=o_yellow.png border=0></a></td><td align=center><a href=http://ubio.org/portal/index.php?search=Cycadopsida+Brongn.+class.&category=l&client=pubmed&startPage=8><img src=o_yellow.png border=0></a></td><td align=center><a href=http://ubio.org/portal/index.php?search=Cycadopsida+Brongn.+class.&category=l&client=pubmed&startPage=9><img src=o_yellow.png border=0></a></td><td align=center><a href=http://ubio.org/portal/index.php?search=Cycadopsida+Brongn.+class.&category=l&client=pubmed&startPage=10><img src=o_yellow.png border=0></a></td><td align=center><a href=http://ubio.org/portal/index.php?search=Cycadopsida+Brongn.+class.&category=l&client=pubmed&startPage=2><img src=rtal.png border=0></a></td></tr><td align=center></td><td align=center>1</td><td align=center><a href=http://ubio.org/portal/index.php?search=Cycadopsida+Brongn.+class.&category=l&client=pubmed&startPage=2>2</a></td><td align=center><a href=http://ubio.org/portal/index.php?search=Cycadopsida+Brongn.+class.&category=l&client=pubmed&startPage=3>3</a></td><td align=center><a href=http://ubio.org/portal/index.php?search=Cycadopsida+Brongn.+class.&category=l&client=pubmed&startPage=4>4</a></td><td align=center><a href=http://ubio.org/portal/index.php?search=Cycadopsida+Brongn.+class.&category=l&client=pubmed&startPage=5>5</a></td><td align=center><a href=http://ubio.org/portal/index.php?search=Cycadopsida+Brongn.+class.&category=l&client=pubmed&startPage=6>6</a></td><td align=center><a href=http://ubio.org/portal/index.php?search=Cycadopsida+Brongn.+class.&category=l&client=pubmed&startPage=7>7</a></td><td align=center><a href=http://ubio.org/portal/index.php?search=Cycadopsida+Brongn.+class.&category=l&client=pubmed&startPage=8>8</a></td><td align=center><a href=http://ubio.org/portal/index.php?search=Cycadopsida+Brongn.+class.&category=l&client=pubmed&startPage=9>9</a></td><td align=center><a href=http://ubio.org/portal/index.php?search=Cycadopsida+Brongn.+class.&category=l&client=pubmed&startPage=10>10</a></td><td align=center><a href=http://ubio.org/portal/index.php?search=Cycadopsida+Brongn.+class.&category=l&client=pubmed&startPage=2>»</a></td></tr></table></table></tr></table></td><script src="http://www.google-analytics.com/urchin.js" type="text/javascript"> </script> <script type="text/javascript"> _uacct = "UA-634822-1"; urchinTracker(); </script> </BODY> </HTML>
