Morphologic And Taxonomic Analysis Of The Weedy And Cultivated Amaranthus Hybridus Species Complex, Dinesh Adhikary, Donald B. Pratt Jan 2015

Morphologic And Taxonomic Analysis Of The Weedy And Cultivated Amaranthus Hybridus Species Complex, Dinesh Adhikary, Donald B. Pratt

Faculty Publications

The hybridus species complex of the genus Amaranthus is a group of weedy and cultivated plants from the New World that are considered difficult to identify. Classification schemes have varied between a single species approach, Amaranthus hybridus s.l., and a five species approach that recognizes the widespread weedy A. hybridus s.s., the South American endemic A. quitensis, and the three cultivated taxa (A. hypochondriacus, A. cruentus, and A. caudatus) as distinct species. The goals of this study were to analyze patterns of floral variation within the species complex and to determine distinguishing morphological features of the species. Twenty-one ...

Microarrays offer a powerful tool for diverse applications plant biology and crop improvement. Recently, two comprehensive assemblies of cotton ESTs were constructed based on three Gossypium species. Using these assemblies as templates, we describe the design and creation and of a publicly available oligonucleotide array for cotton, useful for all four of the cultivated species. Results: Synthetic oligonucleotide probes were generated from exemplar sequences of a global assembly of 211,397 cotton ESTs derived from <50 different cDNA libraries representing many different tissue types and tissue treatments. A total of 22,787 oligonucleotide probes are included on the arrays, optimized to target the diversity of the transcriptome and previously studied cotton genes, transcription factors, and genes with homology to Arabidopsis. A small portion of the oligonucleotides target unidentified protein coding sequences, thereby providing an element of gene discovery. Because many oligonucleotides were based on ESTs from fiber-specific cDNA libraries, the microarray has direct application for analysis of the fiber transcriptome. To illustrate the utility of the microarray, we hybridized labeled bud and leaf cDNAs from G. hirsutum and demonstrate technical consistency of results. Conclusion: The cotton oligonucleotide microarray provides a reproducible platform for transcription profiling in cotton, and is made publicly available through http://cottonevolution.info.

Conidial Germination And Infection By Diplocarpon Rosae On Susceptible And Resistant Rose Species, Robert J. Wiggers, J. G. West, Josephine Taylor Jan 1997

Conidial Germination And Infection By Diplocarpon Rosae On Susceptible And Resistant Rose Species, Robert J. Wiggers, J. G. West, Josephine Taylor

Faculty Publications

Conidial germination and infection by Dipplocarpon rosae, the causal organism of rose blackspot, were examined on two resistant species of roses, Rosa roxburghii and R. wichuraiana and two susceptible hybrid tea roses (R. hybrid cv. Chicago Peace and Garden Party). Fungal conidia germinated and gave rise to subcuticular mycelium that formed haustoria within epidermal cells of all four roses tested. On the resistant rose species, epidermal cells associated with the infection site became necrotic, indicating that a hypersensitive response is involved in conferring their resistance D. rosae.
