  • Exploiting the Potential of Agave for Bioenergy in Marginal Lands Dalal
    Exploiting the Potential of Agave for Bioenergy in Marginal Lands Dalal Bader Al Baijan A Thesis submitted for the Degree of Doctor of Philosophy School of Biology Newcastle University July 2015 Declaration I hereby certify that this thesis is the result of my own investigations and that no part of it has been submitted for any degree other than Doctor of Philosophy at the Newcastle University. All references to the work of others have been duly acknowledged. Dalal B. Al Baijan ii “It is not the strongest of the species that survives, nor the most intelligent, but the one most responsive to change” Charles Darwin Origin of Species, 1859 iii Abstract Drylands cover approximately 40% of the global land area, with minimum rainfall levels, high temperatures in the summer months, and they are prone to degradation and desertification. Drought is one of the prime abiotic stresses limiting crop production. Agave plants are known to be well adapted to dry, arid conditions, producing comparable amounts of biomass to the most water-use efficient C3 and C4 crops but only require 20% of water for cultivation, making them good candidates for bioenergy production from marginal lands. Agave plants have high sugar contents, along with high biomass yield. More importantly, Agave is an extremely water-use efficient (WUE) plant due to its use of Crassulacean acid metabolism. Most of the research conducted on Agave has centered on A. tequilana due to its economic importance in the tequila production industry. However, there are other species of Agave that display higher biomass yields compared to A.

The family has been divided in five tribes: Ampelopsideae, Cisseae, Cayratieae, Parthenocisseae and Viteae. Seed shape is variable in this family. Based on new models derived from equations representing heart and water drop curves, we describe seed shape in species of the Vitaceae. According to their similarity to geometric models, the seeds of the Vitaceae have been classified in ten groups. Three of them correspond to models before described and shared with the Arecaceae (lenses, superellipses and elongated water drops), while in the seven groups remaining, four correspond to general models (waterdrops, heart curves, elongated heart curves and other elongated models) and three adjust to the silhouettes of seeds in particular genera (heart curves of Cayratia and Pseudocayratia, heart curves of the Squared Heart Curve (SqHC) type of Ampelocissus and Ampelopsis and Elongated Superellipse-Heart Curves (ESHCs), frequent in Tetrastigma species and observed also in Cissus species and Rhoicissus rhomboidea).

R. China Seventy-nine species representing 12 genera of Vitaceae were sequenced for the trnL-F spacer, 37 of which were subsequently sequenced for the atpB-rbcL spacer and the rps16 intron. Phylogenetic analysis of the combined data provided a fairly robust phylogeny for Vitaceae. Cayratia, Tetrastigma, and Cyphostemma form a clade. Cyphostemma and Tetrastigma are each monophyletic, and Cayratia may be paraphyletic. Ampelopsis is paraphyletic with the African Rhoicissus and the South American Cissus striata nested within it. The pinnately leaved Ampelopsis form a subclade, and the simple and palmately leaved Ameplopsis constitutes another with both subclades containing Asian and American species. Species of Cissus from Asia and Central America are monophyletic, but the South American C. striata does not group with other Cissus species. The Asian endemic Nothocissus and Pterisanthes form a clade with Asian Ampelocissus, and A. javalensis from Central America is sister to this clade. Vitis is monophyletic and forms a larger clade with Ampelocissus, Pterisanthes, and Nothocissus. The eastern Asian and North American disjunct Parthenocissus forms a clade with Yua austro-orientalis, a species of a small newly recognized genus from China to eastern Himalaya.

Schweickerdt Herbarium, Department of Botany, University of Pretoria, Pre toria, 0002 Republic of South Africa Reaived 2 January 1996; revised 10 April /996 Cyphostemma rubroglandulosum Relief & Van Wyk, a new species from South Africa, is described, illustrated and compared with other members of the genus in southern Africa. It is a climbing, succulent herb with conspicuous, red, multicellular, glandular hairs on the stems, leaves and inriorescences. The combination of glandular hairs, 3-foliolate leaves, and fruits with scattered , multicellular hairs distinguishes it from all other members of the genus in southern Africa. Pollen grains are 3-zonocolporate with a reticu late tectum; the closely spaced pores differ in shape and size.
