Pollen And Seed Morphology Of The Genus Hesperis L. (Brassicaceae) In Turkey, Münevver Pinar, Ahmet Duran, Tali̇p Çeter, G. Ni̇lhan Tuğ Jan 2009

Pollen And Seed Morphology Of The Genus Hesperis L. (Brassicaceae) In Turkey, Münevver Pinar, Ahmet Duran, Tali̇p Çeter, G. Ni̇lhan Tuğ

Turkish Journal of Botany

Pollen and seed morphology were examined in 35 specimens representing 25 Turkish species of the taxonomically complex genus Hesperis L. by light and scanning electron microscopes. Three main types and 2 subtypes were recognized based on the seed coat surface, pollen shape, and exine sculpturing. The seed coat ornamentation of Type I was ocellate, and pollen shape was oblate-spheroidal. While Type II was represented by reticulate seed coat and prolate-spheroidal pollen shape, Type III had tuberculate seed coat. This study revealed that both palynological and seed morphological characters are of significant importance in the taxonomy of the genus.

Phylogenetic Analyses Of Amaranthaceae Based On Matk Dna Sequence Data With Emphasis On West African Species, Oluwatoyin T. Ogundipe, Mark Chase Jan 2009

Phylogenetic Analyses Of Amaranthaceae Based On Matk Dna Sequence Data With Emphasis On West African Species, Oluwatoyin T. Ogundipe, Mark Chase

Turkish Journal of Botany

Comparative sequencing of the chloroplast matK coding and non-coding regions was used to examine relationship among the species of Amaranthaceae with emphasis on the West African species and other closely related family such as Chenopodiaceae, Portulacaceae, and Caryophyllaceae. Phylogenetic analysis of the matK sequences alone and in combination using maximum parsimony methods produced monophyletic lineage of Amaranthaceae-Chenopodiaceae. Our results indicated that a polyphyletic Celosieae as sister to an Amaranthus-Chemissoa lineage. Subfamily Amaranthoideae is paraphyletic to the core Gomphrenoids. This study also shows that the polyphyly of Amarantheae is apparent and so is the polyphyly of Amaranthinae.

Study Of Seasonal Influences On Algal Biodiversity In The River Yarqon (Central Israel) By Bio-Indication And Canonical Correspondence Analysis (Cca), Sophia Barinova, Moti Tavassi

Turkish Journal of Botany

In our research conducted in the River Yarqon during 2003-2006, we identified 313 taxa of algae and cyanobacteria belonging to 8 taxonomical divisions. Out of these 313 taxa, 268 taxa (85.6%) were indicators of environmental conditions that characterised the river water as alkaline with medium mineralisation. In the rainy and dry seasons the algal taxonomic compositions were very different, with prevailing diatoms in the winter and cyabobacteria and greens in summer. Bio-indication shows that the taxonomic preference for the self-purification process was more intensive during the rainy season, while the low level of river water in the dry season stressed …

7tmrmine: A Web Server For Hierarchical Mining Of 7tmr Proteins, Guoqing Lu, Zhifang Wang, Alan M. Jones, Etsuko N. Moriyama Jan 2009

7tmrmine: A Web Server For Hierarchical Mining Of 7tmr Proteins, Guoqing Lu, Zhifang Wang, Alan M. Jones, Etsuko N. Moriyama

Center for Plant Science Innovation: Faculty Publications

Background: Seven-transmembrane region-containing receptors (7TMRs) play central roles in eukaryotic signal transduction. Due to their biomedical importance, thorough mining of 7TMRs from diverse genomes has been an active target of bioinformatics and pharmacogenomics research. The need for new and accurate 7TMR/GPCR prediction tools is paramount with the accelerated rate of acquisition of diverse sequence information. Currently available and often used protein classification methods (e.g., profile hidden Markov Models) are highly accurate for identifying their membership information among already known 7TMR subfamilies. However, these alignment-based methods are less effective for identifying remote similarities, e.g., identifying proteins from highly divergent or possibly …

Oxygenase Coordination Is Required For Morphological Transition And The Host–Fungus Interaction Of Aspergillus Flavus, Sigal Horowitz Brown, James B. Scott, Jeyanthi Bhaheetharan, William C. Sharpee, Lane Milde, Richard A. Wilson

Fungal Molecular Plant-Microbe Interactions

Oxylipins, a class of oxygenase-derived unsaturated fatty acids, are important signal molecules in many biological systems. Recent characterization of an Aspergillus flavus lipoxygenase gene, lox, revealed its importance in maintaining a density-dependent morphology switch from sclerotia to conidia as population density increased. Here, we present evidence for the involvement of four more oxylipingenerating dioxygenases (PpoA, PpoB, PpoC, and PpoD) in A. flavus density-dependent phenomena and the effects of loss of these genes on aflatoxin production and seed colonization. Although several single mutants showed alterations in the sclerotia-to-conidia switch, the major effect was observed in a strain downregulated for all …

Fungal Physiology: A Future Perspective, Richard A. Wilson, Nicholas J. Talbot Jan 2009

Fungal Physiology: A Future Perspective, Richard A. Wilson, Nicholas J. Talbot

Fungal Molecular Plant-Microbe Interactions

The study of fungal physiology is set to change dramatically in the next few years as highly scalable technologies are deployed allowing accurate measurement and identification of metabolites, proteins and transcripts within cells. The advent of next-generation DNA-sequencing technologies will also provide genome sequence information from large numbers of industrially relevant and pathogenic fungal species, and allow comparative genome analysis between strains and populations of fungi. When coupled with advances in gene functional analysis, protein-protein interaction studies, live cell imaging and mathematical modelling, this promises a step-change in our understanding of how fungal cells operate as integrated dynamic living systems

Under Pressure: Investigating The Biology Of Plant Infection By Magnaporthe Oryza, Nicholas J. Talbot, Richard A. Wilson Jan 2009

Under Pressure: Investigating The Biology Of Plant Infection By Magnaporthe Oryza, Nicholas J. Talbot, Richard A. Wilson

Fungal Molecular Plant-Microbe Interactions

The filamentous fungus Magnaporthe oryzae causes rice blast, the most serious disease of cultivated rice. Cellular differentiation of M. oryzae forms an infection structure called the appressorium, which generates enormous cellular turgor that is sufficient to rupture the plant cuticle. Here, we show how functional genomics approaches are providing new insight into the genetic control of plant infection by M. oryzae. We also look ahead to the key questions that need to be addressed to provide a better understanding of the molecular processes that lead to plant disease and the prospects for sustainable control of rice blast.

Processing And Storage Effects On The Polyphenolic Content And Antioxidant Capacity Of Conventional And Sugar-Free Blueberry Jams, Chelsea Castrodale, Luke Howard, Cindi Brownmiller

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Fresh blueberries have received much attention due to their positive role in human health and disease prevention. The abundance of polyphenolics, namely anthocyanins and procyanidins, is thought to play an important role in health promotion. Due to seasonal availability and limited shelf-life, blueberries are commonly preserved and consumed in various thermally processed forms (jams, juices, canned whole fruit, and purées). Both conventional high sugar and sugar-free blueberry jams are available on the market, but no information is available on how different formulations, processing conditions, and storage of processed jams affect the retention of polyphenolics and antioxidant capacity found in fresh …
