Determination Of Phytogenetic Relationships Among Isoetes Species Using Random Primers, Yogendra K. Tripathi, Priyatansh Gurha, D. Ghosh, R. V. Kumar, Ved Prakash Jan 2007

Determination Of Phytogenetic Relationships Among Isoetes Species Using Random Primers, Yogendra K. Tripathi, Priyatansh Gurha, D. Ghosh, R. V. Kumar, Ved Prakash

Turkish Journal of Botany

Isoetes L. is an ancient, primitive genus of lycopsids. The genus occupies a unique position in plant evolution as the closest relatives of tree lycopods. The morphological characters, namely leaf size, comb, and sporophyll size, are used diagnostically to help in the identification of the Isoetes species. Thus, species identification of Isoetes is always problematic and the knowledge on the genetic relationship of Isoetes species is also limited. Therefore, in order to find a suitable method for species identification and estimation of genetic relationship among different species of Isoetes, a Random Amplified Polymorphic DNA (RAPD) technique based on Polymerase Chain …

Floral Biology, Breeding System, And Pollination Ecology Of Cucurbita Moschata (Duch. Ex Lam) Duch. Ex Poir. Varieties (Cucurbitaceae) From Parts Of The Niger Delta, Nigeria, Ikechukwu Ozoemenam Agbagwa, Benjamin Chinyem Ndukwu, Stephen I. Mensah

Turkish Journal of Botany

Flowering, breeding mechanisms, and pollination biology of Cucurbita moschata (Duch. ex Lam) Duch. ex Poir. varieties were studied. C. moschata carries male and female flowers on the same plant and is pollinated by thrips and bees with nectar and pollen as major rewards for the pollinators. Both flowers begin opening between 0330 and 0400 hours. The male flower opens for about 8 to 9 h and the female opens for 6 h 30 min to 7 h. There is, however, a period of overlap in the flower anthesis of both sexes, which coincides with the peak of pollen viability and …

Cell Wall Proteome In The Maize Primary Root Elongation Zone. Ii. Region-Specific Changes In Water Soluble And Lightly Ionically Bound Proteins Under Water Deficit1[W][Oa], Jinming Zhu, Sophie Alvarez, Ellen L. Marsh, Mary E. Lenoble, In-Jeong Cho, Mayandi Sivaguru, Sixue Chen, Henry T. Nguyen, Yajun Wu, Daniel P. Schachtman, Robert E. Sharp

Department of Agronomy and Horticulture: Faculty Publications

Previous work on the adaptation of maize (Zea mays) primary roots to water deficit showed that cell elongation is maintained preferentially toward the apex, and that this response involves modification of cell wall extension properties. To gain a comprehensive understanding of how cell wall protein (CWP) composition changes in association with the differential growth responses to water deficit in different regions of the elongation zone, a proteomics approach was used to examine water soluble and loosely ionically bound CWPs. The results revealed major and predominantly region-specific changes in protein profiles between well-watered and water-stressed roots. In total, 152 …

Map Location Of The Rpp1 Locus That Confers Resistance To Soybean Rust In Soybean, D. L. Hyten, G. L. Hartman, R. L. Nelson, R. D. Frederick, V. C. Concibido, J. M. Narvel, P. B. Cregan

Department of Agronomy and Horticulture: Faculty Publications

Soybean rust (SBR), caused by Phakopsora pachyrhizi, was first discovered in North America in 2004 and has the potential to become a major soybean [Glycine max (L.) Merr.] disease in the USA. Currently, four SBR resistance genes have been identifi ed but not mapped on the soybean genetic linkage map. One of these resistance genes is the Rpp1 gene, which is present in the soybean accession PI 200492. The availability of molecular markers associated with Rpp1 will permit marker-assisted selection and expedite the incorporation of this gene into U.S. cultivars. We compared simple sequence repeat (SSR) markers between …

Waters, Carlos Lucena, Francisco J. Romera, Gena G. Jester, April N. Wynn, Carmen L. Rojas, Esteban Alcántara, Rafael Pérez-Vicente Jan 2007

Ethylene Involvement In The Regulation Of The H+-Atpase Csha1 Gene And Of The New Isolated Ferric Reductase Csfro1 And Iron Transporter Csirt1 Genes In Cucumber Plants, Brian M. Waters, Carlos Lucena, Francisco J. Romera, Gena G. Jester, April N. Wynn, Carmen L. Rojas, Esteban Alcántara, Rafael Pérez-Vicente

Department of Agronomy and Horticulture: Faculty Publications

In previous works using ethylene inhibitors and precursors, it has been shown that ethylene participates in the regulation of several Fe-deficiency stress responses by Strategy I plants, such as enhanced ferric reductase activity, rhizosphere acidification, and subapical root hair development. Furthermore, recent evidence suggests that ethylene could regulate the expression of both the ferric reductase and the iron transporter genes of Strategy I plants by affecting the FER (or FER-like) transcription factor. Recently, two H+-ATPase genes have been isolated from cucumber roots, CsHA1 and CsHA2. CsHA1 is up-regulated under Fe deficiency while CsHA2 is constitutively expressed. In …

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 Jan 2007

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 staining in fertile …

Array-Based Genotyping And Expression Analysis Of Barley Cv. Maythorpe And Golden Promise, Harkamal Walia, Clyde Wilson, Pascal Condamine, Abdelbagi M. Ismail, Jin Xu, Xinping Cui, Timothy J. Close Jan 2007

Array-Based Genotyping And Expression Analysis Of Barley Cv. Maythorpe And Golden Promise, Harkamal Walia, Clyde Wilson, Pascal Condamine, Abdelbagi M. Ismail, Jin Xu, Xinping Cui, Timothy J. Close

Department of Agronomy and Horticulture: Faculty Publications

Background: Golden Promise is a salt-tolerant spring barley closely related to Maythorpe. Salt tolerance in Golden Promise has been attributed to a single mutation at the Ari-e locus (on 5H) resulting from irradiation of Maythorpe. Golden Promise accumulates lower shoot Na+ compared to Maythorpe when growing under saline conditions. This study focused on elucidating the genetic basis and mechanisms involved in this difference. Results: The level of polymorphism between the two genotypes was explored using the Barley1 GeneChip for single feature polymorphisms (SFPs) and an oligonucleotide pool assay for single nucleotide polymorphisms (SNPs). Polymorphism analyses revealed three haplotype blocks …

Nutrient Use Efficiency: Measurement And Management, Achim Dobermann Jan 2007

Nutrient Use Efficiency: Measurement And Management, Achim Dobermann

Department of Agronomy and Horticulture: Faculty Publications

Mineral fertilizers have sustained world agriculture and thus global population and wealth growth for more than 100 years (Smil, 2001; Stewart et al., 2005). Their contribution to increasing crop yields has spared millions of hectares of natural ecosystems that otherwise would have been converted to agriculture (Balmford et al., 2005). However, lacking, imbalanced, inappropriate or excessive use of nutrients in agricultural systems remains a concern. Nutrient mining is a major cause for low crop yields in parts of the developing world, particularly Africa. In other situations, nutrients such as nitrogen (N) and phosphorus (P) often move beyond the bounds of …

Genetic Diversity Among Nile Delta Isolates Of Rhizoctonia Solani Kühn Based On Pathogenicity, Compatibility, Isozyme Analysis And Total Protein Pattern, Yehia A.G. Mahmoud, Reda M. Gaafar, H. M. Mubarak

Turkish Journal of Botany

The present study obtained 12 isolates from Rhizoctonia solani Kühn isolated from Cotton L., Trifolium L. and Vicia faba L. from different localities in the Nile Delta of Egypt. All strains were pathogenic and caused seed rot, wilt, stunting, and pre-emergence and post-emergence damping-off. The isolated strains produced different forms of infection cushions that ensure the pathogenicity of these strains. SDS-PAGE of the 12 R. solani isolates showed that although the R. solani isolates were isolated from very divergent host plants, the total soluble protein patterns among them were similar. Isozyme analysis revealed higher polymorphism among R. solani isolates using …
