The present study aims to identify Neofusicoccum isolates collected from lotus with symptoms of dieback, blight, and wilted leaves. Species were identified based on their morphology and comparison of the DNA sequence data for ITS rDNA and β-tubulin (tub-2). The taxonomy and phylogenetic relationships of pathogen isolates were investigated, and their pathogenic abilities were determined.

In Vietnam, SMEDI syndrome in sows caused by PPV is nationwide and has been of concern since the early 1990s. Previous studies have investigated the prevalence of PPVs using serological testing and PCR methods. The objective of this study is to analyze the genotypic prevalence of PPVs and molecular characterization of VP gene of PPV2 from slaughtered pigs in Central Vietnam.

The genus Sphagnum is one of the richest taxa among the Turkish bryophytes. Up to now, it has been represented by 27 taxa in six sections (Sphagnum, Acutifolia, Squarrosa, Subsecunda, Cuspidata, and Rigida). In this study, an identification key for the section Sphagnum was prepared, and the section was investigated using phylogenetic analyses, with a main focus on Turkish bryophytes. This study provides the first sequence data of the trnL intron region for five species of the section Sphagnum from Turkey (namely S. centrale, S. divinum, S. medium, S. palustre, and S.

In the present study, trichomes of 70 spp. from nine genera and pollens of 53 spp. from six genera were investigated using scanning electron microscopy (SEM) in order to draw the taxonomic conclusion of tribe Stachydeae. Trichome characters that can provide adequate variation in delimitation of taxa were: presence or absence of glandular or nonglandular trichomes, number of cells (uni-/bi-/multicellular), presence of extremely long trichomes (i.e.

Two species of Whalleya from Guizhou and Hainan Provinces were collected during the investigation of Xylariales from 2019 to 2021. According to morphological and molecular characteristics, Whalleya hainanensis sp. nov. and W. microplaca are introduced. Whalleya hainanensis differs from W. microplaca by its obovoid or tubular perithecia and the slightly raised stromata; and differs from W. maculata by its smaller ascospores. Their detailed morphological descriptions and illustrations are provided. The taxonomic position of Whalleya is discussed.

Grasslands in the Arctic tundra undergo irreversible degradation due to climatic changes and also over-exploitation and depletion of scarce resources. Comprehensive investigations of cytogenomic structures of valuable Arctic and sub-Arctic grassland species is essential for clarifying their genetic peculiarities and phylogenetic relationships, and also successful developing new forage grass cultivars with high levels of adaptation, stable productivity and longevity.

CesA and Csl gene families, which belong to the cellulose synthase gene superfamily, plays an important role in the biosynthesis of the plant cell wall. Although researchers have investigated this gene superfamily in several model plants, to date, no comprehensive analysis has been conducted in the common bean.

In this study, we have sequences nuclear gene region (ITS-rDNA) from 9 individuals of Tacca chantrieri André belonging to three natural populations (Song Hinh Nature Reserve, Phu Yen Province; Cuc Phuong National Park, Ninh Binh province and Ba Vi National Park, Ha Noi city) to investigate genetic character and their phylogenetic inference in the genus Tacca. DNA was extracted from the tissue of leaves.

Porcine circovirus type 2 (PCV2) is the pathogen of porcine circovirus associated diseases (PCVAD) and one of the main pathogens in the global pig industry, which has brought huge economic losses to the pig industry. In recent years, there has been limited research on the prevalence of PCV2 in Henan Province. This study investigated the genotype and evolution of PCV2 in this area.

Feline immunodeficiency virus (FIV) and feline leukemia virus (FeLV) are typical retroviruses that are transmitted horizontally among felines. FIV results in symptoms of immunodeficiency such as weight loss, chronic lesions, opportunistic infections, and neurological abnormalities, while FeLV is known to cause a variety of neoplastic and nonneoplastic diseases in cats, such as thymic lymphoma, multicentric lymphoma myelodysplastic syndromes, acute myeloid leukemia, aplastic anemia, and immunodeficiency.

Ablepharus Lichtenstein, 1823, which includes ten species, is distributed in eastern Europe and Asia. Four species are recorded in Turkey: A. kitaibelii, A. chernovi, A. bivittatus, and A. budaki. After molecular and morphological studies in Anatolia, the phylogenetic relationship of the genus is still very complicated. Here, we investigate the taxonomic status of Ablepharus in Anatolia using morphological and molecular methods. The genetic structure of Ablepharus populations in Anatolia was analyzed using both the nuclear (CMOS) and mitochondrial (cyt b and COI) gene regions.

The codling moth (Cydia pomonella L., Lepidoptera: Tortricidae) is a well-known pest worldwide and was first reported in 1952 in Turkey. It is traditionally controlled with several pesticide applications during each apple production season. The genetic diversity of codling moths was investigated in this study, based on the partial mitochondrial cytochrome oxidase subunite I gene. Twenty-two haplotypes from 9 populations were studied. The results showed an average haplotype and nucleotide diversity of 0.835 and 0.571, respectively.

The CBL-interacting protein kinase (CIPK) gene family plays important roles in plant growth, development, and responses to abiotic stresses. To date, the CIPKs have been extensively identified and characterized in various plants. However, there have been few studies on CIPKs in Dimocarpus longan Lour (D. longan). In this study we identified eight putative CIPKs in D. longan (DlCIPKs) according to RNA-seq data.

The aim of this paper was to determine how the pistachio trees evolve, and the evolving factors that influence pistachio population establishment. For that, we investigated pistachio genetic structure from some regions of Tunisia, by sequencing two noncoding chloroplastic regions (trnL (UAA) and trnL-trnF intergenic spacer). We found strong genetic diversity among groups, with the absence of high differentiation between population pairs. A deep phylogeographical break separated two major clusters: “El-Guetar and “Gafsa/Sidi-Bouzid.

Rheum palmatum has been widely developed in traditional Chinese medicine. One of the major active compounds in R. palmatum is flavonoids. Until now, few genes involved in flavonoid biosynthesis have been isolated from this medicinal plant. In this study, a new chalcone isomerase gene (RpCHI) was cloned from an RNA-seq library of R. palmatum. The 714bp RpCHI cDNA was cloned and sequenced.

Saintpaulia ionantha H. Wendl (synonym Streptocarpus ionanthus) has been considered an ornamental plant. The PHANTASTICA (PHAN) gene has a significant role in the formation of plant organs adaxial–abaxial polarity. In the present study the PHAN gene was identified in Saintpaulia for the first time using PCR. To determine the expression pattern of the PHAN gene, gene expression was compared at 3 developmental stages using real time PCR.
