Author:Walford, Sally-AnnDate:2008The 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
Author:Mtwisha, Linda; Farrant, Jill M; Brandt, Wolf; Hlongwane, Caswell; Lindsey, George GDate:2007ASP53, 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
Author:Loffell, D. A.Date:2002Xerophyta 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
Author:Bergh, Nicola GDate:1998There 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
Author:Ncanana, Sandile WelcomeDate:2003Eragrostis 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
Author:Vicre, MaїtéDate:2001Resurrection 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
Author:Neumann, Alexis JoyDate:2013The 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
Author:Fan, CynthiaDate:2016In 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
Author:Tshabuse, FreedomDate:2018Drought 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
Author:Dzobo, KevinDate:2005Polyphenols 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
Author:Mulako, InongeDate:2008The 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
Author:Ginbot, Zekarias GebremedhinDate:2011Studies 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
Author:Brocklehurst, DavidDate:2004The 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
Author:Ngubane, Nqobile A CDate:2008The 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
Author:Rojoa, N ZDate:2002The 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
Author:Farrant, Jill M; Lehner, Arnaud; Cooper, Keren; Wiswedel, StefanDate:2009As 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
Author:Hilgart, AmeliaDate:2016The 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
