Echinochloa (Poaceae) includes two domesticated species,Echinochloa utilis (Japanese barnyard millet) andE. frumentacea (Indian sawa millet) and 20–30 wild species. The two millets are morphologically very variable and overlap in spikelet and inflorescence characteristics. Both species are hexaploids based on x = 9. Cytogenetic studies point to the hexaploid wild speciesE. crusgalli andE. colona as possible progenitors ofE. utilis andE. frumentacea, respectively. The tetraploidE. oryzoides is… 
Reproductive System and Molecular Phylogenetic Relationships of Fonio Millets (Digitaria spp., Poaceae) with Some Polyploid Wild Relatives
New information is added about the reproductive system and the evolution of fonio, contributing to the knowledge on their biology, and thus providing useful subsides for future genetic improvement of these valuable crops.
Genetic relationships between peanut and wild species ofArachis sect.Arachis (Fabaceae): Evidence from RAPDs
The investigation showed that RAPDs can be used to analyze both inter- and intraspecific variation in peanut species and indicated that A. duranensis was most closely related to the domesticated peanut and is believed to be the donor of the A genome.
Phylogenetic reconstruction of the genusBrachypodium P. Beauv. (Poaceae) from combined sequences of chloroplastndhF gene and nuclear ITS
A phylogenetic reconstruction of eight species of the genusBrachypodium P. Beauv. (Poaceae) has been obtained combining sequence data from the chloroplastndhF gene and the nuclear ITS, and using five
Intraspecific molecular variation inHieracium sect.Alpina (Asteraceae), an apomictic group
Intraspecific variation of four agamospecies ofHieracium sect. alpina was studied using RAPD and isozyme techniques, and a strong correlation with geography suggests that its cause may be due to polytopic (-polyphyletic?), or perhaps to mutation and dispersal.
Genetic relationship between Echinochloa crus-galli and Echinochloa oryzicola accessions inferred from internal transcribed spacer and chloroplast DNA sequences
Barnyardgrass, hexaploid Echinochloa crus-galli, is considered to arise from the hybridization between tetraploidEchino chloa oryzicola and an unknown diploid species, and the present results suggest that E. oryzicola is the male donor of E. crus- galli, in contrast to their clear divergence in the cpDNA sequence.
Cytogenetic Studies on Two Wild Species of Genus Echinochloa P. Beauv. from Saudi Arabia
The genetic stability of E. colona directly affects seed production, especially at open pollination conditions, in contrast to E. crus-galli, where the heterogenis structure and genetic instability negatively affect seed production at open conditions, insures that the two species undergo openpollination rather than selfpollination, as common in the grass family.
Application of random amplified polymorphic DNA to study genetic diversity in Paspalum scrobiculatum L. (Kodo millet, Poaceae)
The study demonstrated that the RAPD technique can be applied to resolving degrees and patterns of genetic variation at the population and species levels, identifying cultivars, and defining gene pools of this crop.
Genetic and morphologic diversity of Echinochloa crus-galli populations from different origins
High morphological and genetic variability among individual genotypes within geographic locations among E. crus-galli populations would be influenced by agricultural practices, crop characteristics, geographic location and herbicide pressure.
Genetic diversity and herbicide resistance of 15 Echinochloa crus-galli populations to quinclorac in Mekong Delta of Vietnam and Arkansas of United States
Barnyardgrass ( Echinochloa crus-galli ) is one of the worst weeds in rice ( Oryza sativa ), but there are few reports about the genetic diversity and herbicide resistance of barnyardgrass in
Echinochloa Chloroplast Genomes: Insights into the Evolution and Taxonomic Identification of Two Weedy Species
The entire chloroplast genomes of two Echinochloa species (E. oryzicola and E. crus-galli) are completed based on high-throughput sequencing data from their fresh green leaves, contributing to better understanding of the diversification of this genus.


Cytotaxonomic Studies on the Two Cultivated Species and the Wild Relatives in the Genus Echinochloa
It is concluded that E. colona and E. crus-galli do not possess genomic constitution in common, and Indian and Chino-Japanese cultivated strains have been maintained under the specific name, E. frumentacea.
Chloroplast DNA reassociation and grass phylogeny
Sequence variation in chloroplast DNA as measured by DNA reassociation was examined in 12 grass species to address systematic problems in the Poaceae at the subfamilial and tribal levels to indicate a burst of divergence in the family early in its evolution.
Potential taxonomic use of random amplified polymorphic DNA (RAPD): a case study in Brassica
Investigation of RAPDs using Brassica, Sinapis and Raphanus taxa revealed the classical U triangle relationship between diploid and amphidiploid Brassica taxa and suggested at least ten primers are needed to adequately portray these relationships.
Identification of broccoli and cauliflower cultivars with RAPD markers
RAPD (Random Amplified Polymorphic DNA) markers generated by 4 arbitrary 10-mer primers, discriminated 14 broccoli and 12 cauliflower cultivars (Brassica oleracea L.) by banding profiles by finding larger differences for each crop than within the same company.
Use of RAPD markers to determine the genetic diversity of diploid, wheat genotypes
Analysis of RAPD data appears to be helpful in determining the genetic relationships among genotypes, with a higher similarity among T. monococcum than T. urartu.
Isolation of molecular markers for tomato (L. esculentum) using random amplified polymorphic DNA (RAPD)
The original RAPD assay to generate polymorphic DNA markers with a given set of primers was shown to be highly useful in the construction of genetic maps, and has been adapted to tomato.
The use of random amplified polymorphic DNA markers in wheat
In wheat, the non-homoeologous, non-dose responsive and dominant behaviour of RAPD products devalues their use as genetic markers for the construction of linkage maps, and the high probability that the amplified fragments derive from repetitive DNA limits theirUse as a source of conventional RFLP probes.
Ribosomal DNA spacer-length polymorphisms in barley: mendelian inheritance, chromosomal location, and population dynamics.
It is concluded that the rDNA sl variants and/or associated loci are under selection in CCII, which demonstrates that Rrn1 and Rrn2 are useful as new genetic markers.
DNA polymorphisms amplified by arbitrary primers are useful as genetic markers.
A new DNA polymorphism assay based on the amplification of random DNA segments with single primers of arbitrary nucleotide sequence is described, suggesting that these polymorphisms be called RAPD markers, after Random Amplified Polymorphic DNA.

A mathematical model for the evolutionary change of restriction sites in mitochondrial DNA is developed and a measure called "nucleotide diversity" is proposed to express the degree of polymorphism in a population at the nucleotide level.
