Activation of seed-specific genes in leaves and roots of the desiccation tolerant plant, Xerophyta humilis

Author: Walford, Sally-Ann Date: 2008 The ability of tissues to survive almost complete loss of cellular water is a trait found throughout the plant kingdom. While this desiccation tolerance is common in seeds of most angiosperms it is rare in their vegetative tissues. Xerophyta ... Read more
ASP 53, a 53 kDa cupin-containing protein from Acacia erioloba seeds that protects proteins against thermal denaturation

Author: Mtwisha, Linda Date: 2004 Includes bibliographical references (leaves 103-111). Read more
ASP53, a thermostable protein from Acacia erioloba seeds that protects target proteins against thermal denaturation.

Author: Mtwisha, Linda ; Farrant, Jill M ; Brandt, Wolf ; Hlongwane, Caswell ; Lindsey, George G Date: 2007 ASP53, a 53 kDa heat soluble protein, was identified as the most abundant protein in the mature seeds of Acacia erioloba E.Mey. Immunocytochemistry showed that ASP53 was present in the vacuoles and cell walls of the axes and cotyledons of ... Read more
Aspects of the physiology of the resurrection plant Xerophyta Humilis under different environmental conditions

Author: Loffell, D. A. Date: 2002 Xerophyta humilis is a resurrection monocot that is able to survive drying of its tissues to an air-dry state. in order to assess the alidity of laboratory-based experimentation, and the results obtained from such studies, a comparison of ... Read more
Aspects of the prevention of light damage during drying and rehydration of the desiccation-tolerant grass Eragrostis nindensis

Author: Bergh, Nicola G Date: 1998 There are two main mechanisms of desiccation-tolerance in angiosperms. Both of these (poikilochlorophylly and homoiochlorophylly) involve adaptations to prevent light-induced damage as the plants dry and rehydrate. The poikiolchlorophyllous ... Read more
Biolistic-mediated transformation of Eragrostis Curvula with the HSP 12 gene

Author: Ncanana, Sandile Welcome Date: 2003 Eragrostis curvula is a desiccation sensitive monocotyledonous plant and an economically important forage grass in southern Africa. This species has a potential to be improved for drought and salt resistance among other important agronomic ... Read more
Cell wall involvement in desiccation tolerance in the resurrection plant Craterostigma wilmsii

Author: Vicre, Maїté Date: 2001 Resurrection plants have the unique capacity to revive from an air-dried state. In order to cope with desiccation, resurrection plants have to overcome a number of stresses, mechanical stress being one. This occurs when the cytoplasm shrinks ... Read more
Characterisation of galactinol synthase II (XvGolSII) from the resurrection plant Xerophyta viscosa (Baker)

Author: Neumann, Alexis Joy Date: 2013 The monocotyledonous Xerophyta viscosa belongs to a unique group of angiosperms known as resurrection plants. These plants possess a number of unique characteristics which allow them to survive and cope for extended periods with extreme abiotic ... Read more
Characterisation of two desiccation-linked dehydrins from Xerophyta humilis

Author: Fan, Cynthia Date: 2016 In response to abiotic stresses, organisms throughout the plant kingdom, as well as microorganisms and micro-animals such as nematodes or tardigrades, have been observed to express Late Embryogenesis Abundant (LEA) proteins as protective ... Read more
Characterization of membrane lipids and, Changes therein during desiccation and rehydration of the resurrection plant Xerophyta humilis (Bak) Dur and Schinz

Author: Tshabuse, Freedom Date: 2018 Drought is the primary challenge facing agricultural productivity and food sustainability productivity in Africa and many parts of the world. Very few higher plants, including crop plants, can survive periods of extended water loss. However, ... Read more
Characterization of polyphenols in leaves of four desiccation tolerant plant families

Author: Dzobo, Kevin Date: 2005 Polyphenols in plants are known to act as antioxidants, antimicrobials, antifungal, photoreceptors, visual attractors and as light screens. In this study polyphenols in angiosperms found in southern Africa and called resurrection (desiccation ... Read more
Characterization of the Xerophyta humilis desiccation induced-1 (Xhdsi-1voc) gene : a member of the Vicinal Oxygen Chelate (VOC) metalloenzyme superfamily upregulated in X. humilis (BAK) DUR and SCHINZ during desiccation

Author: Mulako, Inonge Date: 2008 The resurrection plant, Xerophyta humilis is used as a model system to identify and characterise genes which play an important role in conferring desiccation tolerance in plants. In this study, the expression of a novel gene named desiccation ... Read more
Characterization of two, desiccation linked, Group 1 LEA proteins from the resurrection plant Xerophyta humilis

Author: Ginbot, Zekarias Gebremedhin Date: 2011 Studies on resurrection plants and other anhydrobiotic organisms show expression of Late Embryogenesis Abundant (LEA) proteins associated with desiccation tolerance. However, the precise role of these proteins has not been described. This ... Read more
Cloning and characterisation of a bZIP transcription factor from a resurrection grass, Eragrostis nindensis

Author: Brocklehurst, David Date: 2004 The G-box is a plant DNA cis-acting element involved in the regulation of gene expression in response to a range of environmental signals including anaerobiosis, dehydration and light as well as by abscisic acid (ABA). Basic leucine zipper ... Read more
Cloning and characterisation of LEA1-EM genes in the resurrection plant, Xerophyta humilis

Author: Ngubane, Nqobile A C Date: 2008 The presence and expressIon patterns of orthologues of LEA group 1 genes has been characterised in the resurrection plant, Xerophyta humilis. The group I LEAs (Em I and Em6) were first identified as proteins that were abundantly and specifically ... Read more
A comparison of leaf sucrose accumulation and regulation between plants of C.Plantagineum dried in the light and dark

Author: Rojoa, N Z Date: 2002 The resurrection plant C. plantagineum is able to survive almost complete water loss in their vegetative tissues and can then rehydrate rapidly on rewatering. The ability to recover completely from dehydration has been attributed in part to ... Read more
Desiccation tolerance in the vegetative tissues of the fern Mohria caffrorum is seasonally regulated

Author: Farrant, Jill M ; Lehner, Arnaud ; Cooper, Keren ; Wiswedel, Stefan Date: 2009 As there is limited information on the mechanisms of vegetative desiccation tolerance in pteridophytes, we undertook a comprehensive anatomical, ultrastructural, physiological and biochemical study on the fern Mohria caffrorum. Our data show ... Read more
Desiccation-induced ultrastructural and biochemical changes in the leaves of the resurrection plant Myrothamnus flabellifolia

Author: Moore, John P ; Hearshaw, Meredith ; Ravenscroft, Neil ; Lindsey, George G ; Farrant, Jill M ; Brandt, Wolf F Date: 2007 Light microscopy and low-temperature scanning electron microscopy were used to systematically compare the surface and internal ultrastructures of hydrated and desiccated leaves of the resurrection plant Myrothamnus flabellifolia (Welw.). This ... Read more
Determination of a robust metabolic barcoding model for chemotaxonomy in Aizoaceae species : expanding morphological and genetic understanding

Author: Hilgart, Amelia Date: 2016 The use of metabolic fingerprints as taxonomic markers is becoming more common. Many studies have found that by comparing the vast metabolic fingerprints of closely related species to each other, secondary metabolites tend to be unique to the ... Read more
Effect of desiccation and storage on the seeds of two related species in the Amaryllidaceae from the western Cape Province

Author: Caplan, Marc Date: 1993 This paper reports results on the first detailed physiological study undertaken on potentially recalcitrant seeds from the western Cape. Germination and dehydration behaviour of two related monocots Boophane flava Barker ex Snijman and Amaryllis ... Read more
