Study of the Molecular Diversity of Internal Transcribed Spacer Region (ITS1.4) in Some Lettuce Genotypes
Lettuce is belong to the Cichorium family with leaf consumption, Annual cold weather plants and rich in minerals, vitamins and nutrients. The aim of the present study was to evaluate the genetic diversity of 15 varieties and lettuce populations using the ITS area. Sequence quality was evaluated using Chromas 2.1.1 software, aligned by MegAlign 5 software and then similarity matrix and dendrogra...
متن کاملMultiple origins and nrDNA internal transcribed spacer homeologue evolution in the Glycine tomentella (Leguminosae) allopolyploid complex.
Despite the importance of polyploidy in the evolution of plants, patterns of molecular evolution and genomic interactions following polyploidy are not well understood. Nuclear ribosomal DNA is particularly complex with respect to these genomic interactions. The composition of nrDNA tandem arrays is influenced by intra- and interlocus concerted evolution and their expression is characterized by ...
متن کاملComparative Evolution of S7 Intron 1 and Ribosomal Internal Transcribed Spacer in Coilia nasus (Clupeiformes: Engraulidae)
Coilia nasus is widely distributed in the Yangtze River, the coastal waters of China, Korea and the Ariake Sound of Japan. Several ecotypes exist and this provides a useful model for the study of comparative diversity between molecular markers. Here we analyze and compare the nucleotide sequences between single-copy ribosomal protein S7 gene intron 1 (rpS7) and multiple-copy ribosomal internal ...
متن کاملMitochondrial and ribosomal internal transcribed spacer 1 diversity of Cimex lectularius (Hemiptera: Cimicidae).
Understanding genetic variation among populations of medically significant pest insects is important in studying insecticide resistance and insect dispersal. The bed bug, Cimex lectularius L. (Hemiptera: Cimicidae), is widespread hematophagus insect pest around the world, including North America, and it has recently been identified as an emerging resurgent pest. To date, no studies have been co...
متن کاملGenetic diversity and molecular evolution of Naga King Chili inferred from internal transcribed spacer sequence of nuclear ribosomal DNA.
Sequences of the Internal Transcribed Spacer (ITS1-5.8S-ITS2) of nuclear ribosomal DNAs were explored to study the genetic diversity and molecular evolution of Naga King Chili. Our study indicated the occurrence of nucleotide polymorphism and haplotypic diversity in the ITS regions. The present study demonstrated that the variability of ITS1 with respect to nucleotide diversity and sequence pol...
