  • Viruses and Virus Diseases of Poaceae (Gramineae)
    Introduction Hervé Lapierre The Poaceae family comprises a very high number of genera and species. The links between these species and other families are still the subject of many adjustments (see chapter 1). The rapid and continual evolution of our knowledge of biochemical proper- ties and of genomic sequences of the different taxa in this plant family keeps widening perspectives to breeders, agronomists and, of course, to pathologists. The detailed studies of the genetic potential of these species allows us to diversify our strategies in the framework of a sustainable agriculture, particularly concerning the control of viruses that still remains difficult. The globalisation of exchanges of cultivated plants started many thousands years ago and was accelerated with the opening of the oceanic spaces in the XVIth century. The four following centuries have seen the diffusion, all over the world, of the main indus- trial and dietary Poaceae. The beginning of our century seems to have initiated the dif- fusion of ornamental Poaceae and parks. The diffusion of Poaceae species in new ecosystems, and, sometimes in very wide areas as well as the rapid modifications of cultivation methods, inevitably brought about modifications of plant/bio-aggressor balances. The methods for fighting viruses as counterparts to other bio-aggressors still often exploit chemical action against the vectors when the natural resistances are low or non-existent. The use of chemical fight- ing methods against these vectors has become a considerable societal issue as are all the new methods using transgenesis. Many analyses focusing on the challenges linked to transgenesis as a method for fighting the viruses of Poaceae are presented in this book.

    Viruses and virus diseases of Poaceae (Gramineae) Viruses The Poaceae are one of the most important plant families in terms of the number of species, worldwide distribution, ecosystems and as ingredients of human and animal food. It is not surprising that they support many parasites including and more than 100 severely pathogenic virus species, of which new ones are being virus diseases regularly described. This book results from the contributions of 150 well-known specialists and presents of for the first time an in-depth look at all the viruses (including the retrotransposons) Poaceae(Gramineae) infesting one plant family. Ta xonomic and agronomic descriptions of the Poaceae are presented, followed by data on molecular and biological characteristics of the viruses and descriptions up to species level. Virus diseases of field grasses (barley, maize, rice, rye, sorghum, sugarcane, triticale and wheats), forage, ornamental, aromatic, wild and lawn Gramineae are largely described and illustrated (32 colour plates). A detailed index Sciences de la vie e) of viruses and taxonomic lists will help readers in their search for information. Foreworded by Marc Van Regenmortel, this book is essential for anyone with an interest in plant pathology especially plant virology, entomology, breeding minea and forecasting. Agronomists will also find this book invaluable. ra The book was coordinated by Hervé Lapierre, previously a researcher at the Institut H. Lapierre, P.-A.

    Systematics of Arundinelleae and Andropogoneae, subtribes Chionachninae, Dimeriinae and Germainiinae (Poaceae: Panicoideae) in Thailand Thesis submitted to the University of Dublin, Trinity College for the Degree of Doctor of Philosophy (Ph.D.) by Atchara Teerawatananon 2009 Research conducted under the supervision of Dr. Trevor R. Hodkinson School of Natural Sciences Department of Botany Trinity College University of Dublin, Ireland I Declaration I hereby declare that the contents of this thesis are entirely my own work (except where otherwise stated) and that it has not been previously submitted as an exercise for a degree to this or any other university. I agree that library of the University of Dublin, Trinity College may lend or copy this thesis subject to the source being acknowledged. _______________________ Atchara Teerawatananon II Abstract This thesis has provided a comprehensive taxonomic account of tribe Arundinelleae, and subtribes Chionachninae, Dimeriinae and Germainiinae of the tribe Andropogoneae in Thailand. Complete floristic treatments of these taxa have been completed for the Flora of Thailand project. Keys to genera and species, species descriptions, synonyms, typifications, illustrations, distribution maps and lists of specimens examined, are also presented. Fourteen species and three genera of tribe Arundinelleae, three species and two genera of subtribe Chionachninae, seven species of subtribe Dimeriinae, and twelve species and two genera of Germainiinae, were recorded in Thailand, of which Garnotia ciliata and Jansenella griffithiana were recorded for the first time for Thailand. Three endemic grasses, Arundinella kerrii, A. kokutensis and Dimeria kerrii were described as new species to science. Phylogenetic relationships among major subfamilies in Poaceae and among major tribes within Panicoideae were evaluated using parsimony analysis of plastid DNA regions, trnL-F and atpB- rbcL, and a nuclear ribosomal DNA region, ITS.

  • DISCUSSION and CONCLUSIONS DISCUSSION and CONCLUSIONS: Danthonidium Gammiei Belongs to Tribe Danthonieae of Subfamily Pooideae
    DISCUSSION AND CONCLUSIONS DISCUSSION AND CONCLUSIONS: Danthonidium gammiei belongs to tribe Danthonieae of subfamily Pooideae. Danthonieae consists of genera viz Centropodia, Danthonia, Danthonidium, Erichne, Schismus and Zenkaria. Danthonia gammiei described by Bhide (1912) was separated into a new genus Danthonidium (Hubbard 1936) which differs from Danthonia in its 1 flowered spikelet, lemma -2 lobed at the tip with very stout awn between the lobes. Leaf anatomy of Danthonidium gammiei shows similarities with genus Danthonia in having long cell with sinuous walls, Panicoid type of microhairs, absence of papillae, fan shaped bulliform cells, mesophyll non radiate form, mid rib conspicuous with single bundle and vascular bundle with sclerenchymatous girders. Danthonia and Danthonidium differ anatomically in some characters* /. Leaves of Danthonidium possess stomata and vertical dumbbell shaped ‘Oryza type’ silica bodies while stomata are absent in Danthonia and leaves possess dumbbell shaped or nodular Panicoid type of silica bodies. This supports separation of Danthonidium from Danthonia. Hubbardia heptaneuron belongs to tribe Hubbardieae of subfamily Pooideae. Bor 1951 described a new monotypic genus Hubbardia from India. The grass was collected However, the grass remained undescribed till father Santapau handed over it to Bor. This grass was collected only on two occasions from clinging rocks near the famous Gersoppa falls on the Sharawati river. The species disappeared from the fall and was declared as possibly extinct from the region (Ahmedullah and M.P.Nayer, 1987) after construction of dam on the Sharawati river and probably drying of Jog falls during summer. It was collected after about 80 years from Tilari Ghat of Kolhapur (Potdar et al 2000).
