cluster analysis; Cynodon dactylon; Genetic diversity; SSR

Fifty-five wild accessions of bermudagrass (Cynodon dactylon) were collected from southwest China (Sichuan, Chongqing, Yunnan, Guizhou, and Tibet), and their genetic diversity was analyzed using simple sequence repeat markers. A total of 267 polymorphic bands were detected with 18 primer combinations. The genetic similarity among the accessions ranged from 0.688 to 0.894 with an ... more

cluster analysis; Genetic diversity; Lagerstroemia; SSR

Lagerstroemia (crape myrtle) are famous ornamental plants with large pyramidal racemes, long flower duration, and diverse colors. However, little is known about the genetic structure and diversity of germplasm in Lagerstroemia. We genotyped 81 L. indica cultivars, five other species of Lagerstroemia, and 10 interspecific hybrids using 30 simple sequence ... more

Chicory; cluster analysis; Genetic diversity; Genetic relationship; Sequence-related amplified polymorphism

Chicory is a crop with economically important roles and is cultivated worldwide. The genetic diversity and relationship of 80 accessions of chicories and endives were evaluated by sequence-related amplified polymorphism (SRAP) markers to provide a theoretical basis for future breeding programs in China. The polymorphic rate was 96.83%, and the average polymorphic information content was ... more

Genetic diversity; Grape phylloxera; Population genetics; Simple sequence repeat marker

A genome-wide sequence search was conducted to identify simple sequence repeat (SSR) loci in phylloxera, Daktulosphaira vitifoliae, a major grape pest throughout the world. Collectively, 1524 SSR loci containing mono-, di-, tri-, tetra-, penta-, and hexanucleotide motifs were identified. Among them, trinucleotide repeats were the most abundant in the phylloxera genome ( ... more

Amino acids; Antioxidant potential; cluster analysis; Isozymes; Random amplified polymorphic DNA; Trigonella foenum-graecum L.

In this study, we analyzed the correlation between genetic variation based on random amplified polymorphic DNA (RAPD), acid phosphatase, and glutamate-oxaloacetate transaminase isozymes, and amino acid composition with the antioxidant potential status of 7 wild Trigonella foenum-graecum L. accessions collected from diverse ecogeographical regions. RAPD revealed that 90 DNA ... more

cluster analysis; Core collection; Germplasm; Malus domestica; Simple sequence repeat

Several types of information can be used to select core collections, including passport data, agronomic data, and molecular data. However, little is known about the ability of core collections to retain the genetic diversity and structure of the whole collection for characters that were not considered during the selection, particularly when molecular markers are used. In this study, two ... more

cluster analysis; Codon usage frequency; Correlation analysis; ENC-plot; FAD7

In this study, the codon bias of the FAD7 genes among 10 different plant species was analyzed to identify general patterns of codon usage in the FAD7 genes. Our results showed that U-ended or A-ended codons were preferentially used in FAD7 for dicots, whereas G-ended or C-ended codons were preferentially used in FAD7 for monocots. An ENC-plot showed ... more

cluster analysis; Molecular markers; Opuntia germplasm; Polymorphism; Random amplified polymorphic DNA; Tunisian collection

Opuntia ficus indica is one of the most economically important species in the Cactaceae family. Increased interest in this crop stems from its potential contribution to agricultural diversification, application in the exploitation of marginal lands, and utility as additional income sources for farmers. In Tunisia, O. ficus indica has been affected by drastic genetic ... more

cluster analysis; Homology analysis; Structural characteristics; Tomato yellow leaf curl virus

The objective of the present study was to analyze the genetic diversity of tomato yellow leaf curl virus (TYLCV). Representative TYLCV sequences were searched in the National Center for Biotechnology Information database. Comprehensive analysis of TYLCV was performed using bioinformatics by examining gene structure, sequence alignments, phylogeny, GC content, and homology. Forty-eight ... more
