The Phylogeny Of Heterocapsa Sp. (Dinophyceae) Isolated From The South Coast Of Iran During A Cochlodinium Polykrikoides Bloom, Gilan Attaran Fariman, Pegah Javid
The Phylogeny Of Heterocapsa Sp. (Dinophyceae) Isolated From The South Coast Of Iran During A Cochlodinium Polykrikoides Bloom, Gilan Attaran Fariman, Pegah Javid
Turkish Journal of Botany
The genus Heterocapsa Stein is a relatively small armoured dinoflagellate. Because it has few differences in morphological characteristics among its species, species identification is difficult. In this study, small Heterocapsa sp. cells associated with a dense bloom of Cochlodinium polykrikoides Margalef were collected from the south-east coast of Iran. While Heterocapsa sp. was isolated, C. polykrikoides could not be isolated by single cell or serial dilution methods. Thus, a unialgal strain of Heterocapsa sp. was used for molecular analysis and species identification. In order to carry out phylogenetic analysis, rDNA was extracted and large subunit domains of D1-D3 were sequenced. …

New Staining Technique For Fungal-Infected Plant Tissues, Joao Paulo Rodrigues Marques, Marli Kasue Misaki Soares, Beatriz Appezzato-Da-Glória
Turkish Journal of Botany
The use of histological techniques, combined with the use of dyes, facilitates the visualisation of fungi present in tissues, allowing the details of plant-pathogen interactions in many different pathosystems to be revealed. The purpose of this study is to present a new double-staining method that uses cotton blue and safranin to identify fungal structures in plant tissues. With this staining method, the fungal hyphae stain blue and plant cell walls stain orange. The new method was tested on 2 pathosystems. The technique distinguishes between fungal and plant cell walls, giving it great practical utility. This is a staining technique that …

When Island-Like Populations At High Elevation Show Genetic Divergence Despite No Morphological Variability: The Case Of Lupinus Montanus In Central Mexico, Maxime Ferval, Luc Legal, Charles Gers, Céline Pélissier, Peter Winterton, Jesús Arnoldo Sánchez López, María Luisa Corona Rangel, Kalina Bermudez Torres
Turkish Journal of Botany
Lupinus montanus subsp. montanus var. montanus Kunth is a widespread taxon occurring throughout the highlands of Central Mexico and Guatemala. Populations of this variety show little variation in plant morphology, but their highly disjunct island-like distribution suggests that genetic differentiation between populations should be expected. To test this idea, we assessed genetic diversity among 13 populations of Lupinus montanus var. montanus growing on the 6 main volcanoes of the Trans-Mexican Volcanic Belt (TMVB) using 4 intersimple sequence repeat markers to quantify genetic divergence. The 93 loci identified showed significant differentiation between populations (F_{ST} \approx 0.5) and high levels of genetic …
