White clover is polymorphic for cyanogenesis, with both cyanogenic and acyanogenic plants occurring in nature. This chemical defense polymorphism is one of the longest-studied and best-documented examples of an adaptive polymorphism in plants. It is controlled by two independently segregating genes: Ac/ac controls the presence/absence of cyanogenic glucosides; and Li/li controls the presence/ab...

The present study evaluated genetic diversity of Lithuanian populations Lythrum salicaria in relation to parameters riparian environment. Growing along Nemunas, Seaside and Lielupė river basins, 15 were examined using amplified fragment length polymorphism markers. Molecular data related the type land use cover, natural vice versa regulated fragments rivers. Population mean as follows: percenta...

Prophet of POU1F1 (PROP1) plays direct or indirect important roles in the morphogenesis of pituitary gonadotropes as well as lactotropes, somatotropes and caudomedial thyrotropes. It also controls the expression of growth hormone, prolactin and thyrotropin subunits through regulatory PIT1 factor. These hormones have important influences on production traits in most animal species including the ...

PURPOSE To evaluate the expression of lumican and decorin, the major proteoglycans of the adult corneal stroma, during the acquisition of corneal transparency in developing chick embryos. METHODS mRNA levels of decorin and lumican were measured in total RNA extracted from corneas of days 9 to 18 of development by Northern blot analysis using a 32P-labeled cDNA clone to each proteoglycan. The ...

morphological and rapd markers were used to investigate the genetic diversity among 21 accessions of pomegranate originating from south eastern tunisia. thirteen morphological traits were studied and results showed significant differences for all morphological characters (p< 0.001). clustering based on fruit traits, using ward’s method, divided the accessions into three main groups. in rapd ana...

retrotransposons (rtns) constitute informative molecular markers for plant species because of their ability to integrate into a multitude of loci throughout the genome and thereby generate insertional polymorphisms between individuals. in the present study, rtn-based molecular markers, irap (inter-retrotransposon amplified polymorphism) and remap (retrotransposon-microsatellite amplified polymo...

Amyloid-beta (Aβ) aggregates are the main constituent of senile plaques, the histological hallmark of Alzheimer’s disease. Aβ molecules form β-sheet containing structures that assemble into a variety of polymorphic oligomers, protofibers, and fibers that exhibit a range of lifetimes and cellular toxicities. This polymorphic nature of Aβ has frustrated its biophysical characterization, its struc...

Molecular markers are used in plant science a variety of ways. The method molecular genome marking based on RAPD-PCR makes it possible to determine the genetic status populations and establish intrapopulation relationships. In this work, we studied polymorphism dandelion Taraxacum officionale using RAPD markers. Five random amplified polymorphic DNA (RAPD) were diversity relationship between tw...
