Highly Variable Patterns Of Linkage Disequilibrium In Multiple Soybean Populations, D. L. Hyten, Ik-Young Choi, Qijian Song, Randy C. Shoemaker, Randall L. Nelson, Jose M. Costa, James E. Specht, P. B. Cregan

Department of Agronomy and Horticulture: Faculty Publications

Prospects for utilizing whole-genome association analysis in autogamous plant populations appear promising due to the reported high levels of linkage disequilibrium (LD). To determine the optimal strategies for implementing association analysis in soybean (Glycine max L. Merr.), we analyzed the structure of LD in three regions of the genome varying in length from 336 to 574 kb. This analysis was conducted in four distinct groups of soybean germplasm: 26 accessions of the wild ancestor of soybean (Glycine soja Seib. et Zucc.); 52 Asian G. max Landraces, the immediate results of domestication from G. soja; 17 Asian Landrace …

The Function Of Stilt Roots In The Growth Strategy Of Socratea Exorrhiza (Arecaceae) At Two Neotropical Sites, Gregory R. Goldsmith, Rakan A. Zahawi

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Arboreal palms have developed a variety of structural root modifications and systems to adapt to the harsh abiotic conditions of tropical rain forests. Stilt roots have been proposed to serve a number of functions including the facilitation of rapid vertical growth to the canopy and enhanced mechanical stability. To examine whether stilt roots provide these functions, we compared stilt root characteristics of the neotropical palm tree Socratea exorrhiza on sloped ( > 20°) and flat locations at two lowland neotropical sites. S. exorrhiza (n=80 trees) did not demonstrate differences in number of roots, vertical stilt root height, root cone circumference, root …

North American Species Of Astragalus Linnaeus (Leguminosae): A Taxonomic Revision, Stanley L. Welsh

Books by Faculty of the Monte L. Bean Life Science Museum

Abstract

This summary revision of the species of Astragalus in North America, north of Mexico, was initially prepared for inclusion in the Flora North America Project. That publication has been postponed indefinitely, and this paper is being presented now to allow those students of the genus with an updated manuscript to review, and to use prior to appearance of the Flora North America treatment. It differs from the Flora North America format in having bibliographic citations to the synonyms, and the type specimens are cited. The present work treats 354 species; 198 varieties; 552 total taxa. Should the 4 7 …

Fertility Restoration Of The Sorghum A3 Male-Sterile Cytoplasm Through A Sporophytic Mechanism Derived From Sudangrass, Hoang V. Tang, Jeffrey F. Pedersen, Christine D. Chase, Daryl R. Pring

Department of Agronomy and Horticulture: Faculty Publications

Fertility restoration of sorghum [Sorghum bicolor (L.) Moench] lines carrying the IS1112C (A3 group) male-sterile cytoplasm has been documented as a two-gene gametophytic mechanism involving complementary action of restoring alleles designated Rf3 and Rf4, as derived from IS1112C. Fertility restoration capability has also been reported from sudangrass (S. bicolor subsp. drummondii) populations. We describe characteristics of a fertility restoration system derived from sudangrass, in which male-sterile individuals were observed at high frequency in backcross and F₂-F₃ segregating populations. Segregation analyses were consistent with a sporophytic restoration system involving two complementary genes. Pollen iodine …

Nutrient Contents Of Pinus Brutia Ten. (Pinaceae) And Pistacia Terebinthus L. (Anacardiaceae) Growing On Marl And Conglomerate Substrata In The Eastern Mediterranean, Hüsni̇ye Aka Sağliker, Cengi̇z Darici

Turkish Journal of Botany

The eastern Mediterranean region is one of the main areas of the Mediterranean vegetation containing Calabrian cluster pine (Pinus brutia Ten., Pinaceae) forests and terebinth (Pistacia terebinthus L., Anacardiaceae) communities. This study was carried out with the leaves, shoots, leaf litters, and soils of Calabrian cluster pine and terebinth growing on both marl and conglomerate substrata in the eastern Mediterranean region (Turkey) to determine average C, N, P and K contents, and the amounts of humic and fulvic acid in these plant soils. The average element contents of leaf, shoot, leaf litter and soil samples of both plants from the …

The Influence Of Certain Physical And Chemical Variables On The Seasonal Dynamics Of Phytoplankton Assemblages Of A Source Inlet And The Outlet Of The Shallow Hypertrophic Lake Manyas, Turkey, Kemal Çeli̇k, Tuğba Ongun

Turkish Journal of Botany

The relationships between water discharge, temperature, pH, conductivity, turbidity, nitrate, ammonium, phosphate and the seasonal dynamics of phytoplankton assemblages of one of the inlets, which is a source of waste for the lake, and the sole outlet of the shallow hypertrophic Lake Manyas, Turkey, were studied from January 2003 to August 2005. Conductivity, ammonium, nitrate, and phosphate concentrations were higher at the inlet than at the outlet. Diatoms and cyanobacteria were the dominant phytoplankton groups at both stations. Achnantes microcephala (Kütz.) Cleve was dominant throughout the year and Microcystis aeruginosa Kütz. was dominant in summer at both stations. Planktothrix rubescens …

Effects Of Salinity: Calcium Interaction On Growth And Nucleic Acid Metabolism In Five Species Of Chenopodiaceae, Essam E. M. Abo-Kassem

Turkish Journal of Botany

Seed germination, seedling growth, and some enzyme activity of nucleic acid metabolism were studied in 5 members of Chenopodiaceae [Beta vulgaris L., Chenopodium quinoa Willd., Spinacea oleracea L., Allenrolfia occidentalis (S.Watson) Kuntze, Atriplex hortensis L.] under NaCl salinity alone or combined with 0.5 mM CaSO_4. High salinity delayed radical emergence and decreased germination percentage in all plants. Combined CaSO_4 reduced inhibition of seed germination in B. vulgaris, S. oleracea, and A. hortensis, but increased it in C. quinoa and A. occidentalis. CaSO_4 reduced plant growth to a greater degree than high salinity did. High salinity decreased total nucleic acid content …

Turkish Journal of Botany

Studies were undertaken for induction of resistance against acute ozone exposure in Rhinacanthus nasutus (L.) Kurz. plants using ozone. Callus induced from Rhinacanthus nasutus leaf explants on Murashige & Skoog's (MS) medium supplemented with 3.40 µM of 2,4-dichlorophenoxy acetic acid (2,4-D) were treated with different concentrations of ozone (T_1 = 1.0 µmol mol^{-1} (±0.2), T_2 = 1.5 µmol mol^{-1} (±0.2), T_3 = 2.0 µmol mol^{-1} (±0.2)), and for the control (C) filtered air was supplied. Regeneration of shoots was obtained by culturing ozone-treated calli on MS medium supplemented with 5.57 µM of kinetin (KIN) and 1.30 µM of gibberellic acid …

The 3 new records for the Myxomycetes in Turkey are as follows: Cribraria languescens Rex, Arcyodes incarnata (Alb. & Schwein.) O.F.Cook., and Macbrideola macrospora (Nann.-Bremek.) Ing.

Combining Ability Analysis Of Yield And Yield Components In Tomato (Lycopersicum Esculentum Mill.), Mohammad Mofidul Hannan, Manosh Kumar Biswas, Mohammad Bulbul Ahmed, Monzur Hossain, Rafiul Islam

Turkish Journal of Botany

The nature of the inheritance of plant height at 60 days, number of flowers per cluster, number of fruits per plant, fruit weight per plant, and number of seeds per fruit was studied from a 10-parent diallel cross of Lycopersicum esculentum Mill. Due to their high general combining ability effects, Pusharubi, Bari-4, and Dynasagor parents were suggested for future hybridisation programmes. For yield, the crosses Deshy x Ratan, Deshy x Epoch, Dynasagor x Ratan, Bari-4 x Pusharubi, and Dynamo x Namdhari had good specific combining ability effects and they were recommended because they produce stable performing rare transgressive segregants. A …

Publishing Ltd Whole-Plant Mineral Partitioning Throughout The Life Cycle In Arabidopsis Thaliana Ecotypes Columbia, Landsberg Erecta, Cape Verde Islands, And The Mutant Line Ysl1ysl3, Brian M. Waters, Michael A. Grusak

Department of Agronomy and Horticulture: Faculty Publications

• Minimal information exists on whole-plant dynamics of mineral flow through Arabidopsis thaliana or on the source tissues responsible for mineral export to developing seeds. Understanding these phenomena in a model plant could help in the development of nutritionally enhanced crop cultivars. • A whole-plant partitioning study, using sequential harvests, was conducted to characterize growth and mineral concentrations and contents of rosettes, cauline leaves, stems, immature fruit, mature fruit hulls, and seeds of three WT lines (Col-0, Ler, and Cvi) and one mutant line (Col-0::ysl1ysl3). • Shoot mineral content increased throughout the life cycle for all minerals, although tissue-specific mineral …
