Leaf Anatomy and C02 Recycling During Crassulacean Acid Metabolism in Twelve Epiphytic Species of Tillandsia (Bromeliaceae)
Int. J. Plant Sci. 154(1): 100-106. 1993. © 1993 by The University of Chicago. All rights reserved. 1058-5893/93/5401 -0010502.00 LEAF ANATOMY AND C02 RECYCLING DURING CRASSULACEAN ACID METABOLISM IN TWELVE EPIPHYTIC SPECIES OF TILLANDSIA (BROMELIACEAE) VALERIE S. LOESCHEN,* CRAIG E. MARTIN,' * MARIAN SMITH,t AND SUZANNE L. EDERf •Department of Botany, University of Kansas, Lawrence, Kansas 66045-2106; and t Department of Biological Sciences, Southern Illinois University, Edwardsville, Illinois 62026-1651 The relationship between leaf anatomy, specifically the percent of leaf volume occupied by water- storage parenchyma (hydrenchyma), and the contribution of respiratory C02 during Crassulacean acid metabolism (CAM) was investigated in 12 epiphytic species of Tillandsia. It has been postulated that the hydrenchyma, which contributes to C02 exchange through respiration only, may be causally related to the recently observed phenomenon of C02 recycling during CAM. Among the 12 species of Tillandsia, leaves of T. usneoides and T. bergeri exhibited 0% hydrenchyma, while the hydrenchyma in the other species ranged from 2.9% to 53% of leaf cross-sectional area. Diurnal malate fluctuation and nighttime atmospheric C02 uptake were measured in at least four individuals of each species. A significant excess of diurnal malate fluctuation as compared with atmospheric C02 absorbed overnight was observed only in T. schiedeana. This species had an intermediate proportion (30%) of hydrenchyma in its leaves. Results of this study do not support the hypothesis that C02 recycling during CAM may reflect respiratory contributions of C02 from the tissue hydrenchyma. Introduction tions continue through fixation of internally re• leased, respired C02 (Szarek et al. -
Indumentum June 2008
TAM end of season - no General meeting Annual Potluck Dinner - sunday june 8, 2008 4:00 p.m. at the home of Joe and joanne ronsley. See Page 7 for the Ronsley’s contact information to obtain directions to their home. www.rhodo.citymax.com President’s Message By Joanne Ronsley The VRS activity year is inexorably drawing to a close—a sad time in some ways, but I think we all need a couple months to recharge. And a quiet, lazy summer, or one of distant adventures, is always appealing. But we do not close with a whimper! Our potluck supper was to be held at the home of Richard and Heather Mossakowski. But due to Richard’s hospital stay, the venue has been changed to the home of Joe and Joeanne Ronsley. The date is the same -Sunday, June 8th, at 4 o’clock. Everyone always has a good time at these events, which have a long tradition dating back all the way to the last century. If you have not signed up to bring a specific item for the menu, please contact either Vern Finley or me. But in any case, don’t miss the event. Our Show and Sale appears to have been quite successful, but I’m afraid I don’t yet have the final figures. They will be available by September. And speaking of September, next year’s speakers’ programme is one we can all look forward to, beginning with Garratt Richardson from Seattle, who has been participating in Asian plant expedition for many years, initially while he was a practicing physician, and since his recent retirement. -

A total of 326 species belonging to 83 families and 219 genera of angiospermic plants have been documented from this area. The largest families are Ericaceae (36 species) and Asteraceae (22 genera). Similarly, the largest and dominant genus was Rhododendron (26 species) in the area. There were 178 herbs, 67 shrubs, 62 trees, 15 climbers and other 4 species of sub-alpine and temperate plants. The paper has attempted to list the plants with their habits and habitats. Key words: alpine, angiospermic flora, conservation, rhododendron Tinjure-Milke-Jaljale Introduction determines overall biodiversity and development The area of Tinjure-Milke-Jaljale (TMJ) falls under the activities. With the increasing altitude, temperature middle Himalaya ranging from 1700 m asl to 5000 m asl, is decreased and consequently different climatic and geographically lies between 2706’57" to 27030’28" zones within a sort vertical distance are found. The north latitude and 87019’46" to 87038’14" east precipitation varies from 1000 to 2400 mm, and the 2 longitude. It covers an area of more than 585 km of average is about 1650 mm over the TMJ region. -

Water Relations of Bromeliaceae in Their Evolutionary Context
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Apollo Botanical Journal of the Linnean Society, 2016, 181, 415–440. With 2 figures Think tank: water relations of Bromeliaceae in their evolutionary context JAMIE MALES* Department of Plant Sciences, University of Cambridge, Downing Street, Cambridge CB2 3EA, UK Received 31 July 2015; revised 28 February 2016; accepted for publication 1 March 2016 Water relations represent a pivotal nexus in plant biology due to the multiplicity of functions affected by water status. Hydraulic properties of plant parts are therefore likely to be relevant to evolutionary trends in many taxa. Bromeliaceae encompass a wealth of morphological, physiological and ecological variations and the geographical and bioclimatic range of the family is also extensive. The diversification of bromeliad lineages is known to be correlated with the origins of a suite of key innovations, many of which relate directly or indirectly to water relations. However, little information is known regarding the role of change in morphoanatomical and hydraulic traits in the evolutionary origins of the classical ecophysiological functional types in Bromeliaceae or how this role relates to the diversification of specific lineages. In this paper, I present a synthesis of the current knowledge on bromeliad water relations and a qualitative model of the evolution of relevant traits in the context of the functional types. I use this model to introduce a manifesto for a new research programme on the integrative biology and evolution of bromeliad water-use strategies. The need for a wide-ranging survey of morphoanatomical and hydraulic traits across Bromeliaceae is stressed, as this would provide extensive insight into structure– function relationships of relevance to the evolutionary history of bromeliads and, more generally, to the evolutionary physiology of flowering plants. -

Ecophysiology of Crassulacean Acid Metabolism (CAM)
Annals of Botany 93: 629±652, 2004 doi:10.1093/aob/mch087, available online at www.aob.oupjournals.org INVITED REVIEW Ecophysiology of Crassulacean Acid Metabolism (CAM) ULRICH LUÈ TTGE* Institute of Botany, Technical University of Darmstadt, Schnittspahnstrasse 3±5, D-64287 Darmstadt, Germany Received: 3 October 2003 Returned for revision: 17 December 2003 Accepted: 20 January 2004 d Background and Scope Crassulacean Acid Metabolism (CAM) as an ecophysiological modi®cation of photo- synthetic carbon acquisition has been reviewed extensively before. Cell biology, enzymology and the ¯ow of carbon along various pathways and through various cellular compartments have been well documented and dis- cussed. The present attempt at reviewing CAM once again tries to use a different approach, considering a wide range of inputs, receivers and outputs. d Input Input is given by a network of environmental parameters. Six major ones, CO2,H2O, light, temperature, nutrients and salinity, are considered in detail, which allows discussion of the effects of these factors, and combinations thereof, at the individual plant level (`physiological aut-ecology'). d Receivers Receivers of the environmental cues are the plant types genotypes and phenotypes, the latter includ- ing morphotypes and physiotypes. CAM genotypes largely remain `black boxes', and research endeavours of genomics, producing mutants and following molecular phylogeny, are just beginning. There is no special development of CAM morphotypes except for a strong tendency for leaf or stem succulence with large cells with big vacuoles and often, but not always, special water storage tissues. Various CAM physiotypes with differing degrees of CAM expression are well characterized. d Output Output is the shaping of habitats, ecosystems and communities by CAM.
