Genetic Diversity among Selected Cultivars Using Inter-Retrotransposon-Amplified Polymorphism, Chloroplast DNA Barcodes and Morpho-Agronomic Trait Analyses.

Alfalfa ( L.) is a major forage crop of family Fabaceae and is frequently cultivated in Egypt. The present study is concerned with the genetic discrimination of fifteen alfalfa cultivars from three different countries (Egypt, Australia, and USA) using two molecular approaches: inter-retrotransposon-amplified polymorphism (IRAP) markers and two chloroplast DNA barcodes K and the H in addition to the analysis of fifteen morpho-agronomic traits.

Evaluation of genetic variation, antioxidant and antibacterial activities of two Sidr varieties in Medina.

Genetic variation of two Ziziphus spina-christi L. (Sidr) varieties was determined by Random Amplified Polymorphic DNA (RAPD). The activity of antioxidant enzymes (peroxidase and catalase) was also determined for the two varieties (Balady and Pakistani).

High-throughput retrotransposon-based genetic diversity of maize germplasm assessment and analysis.

Maize is one of the world's most important crops and a model for grass genome research. Long terminal repeat (LTR) retrotransposons comprise most of the maize genome; their ability to produce new copies makes them efficient high-throughput genetic markers. Inter-retrotransposon-amplified polymorphisms (IRAPs) were used to study the genetic diversity of maize germplasm.

Effect of growth hormones on some antioxidant parameters and gene expression in tomato.

Bioregulators have a great effect on vital processes of plant growth and development. Known plant bioregulators include Naphthalene acetic acid (NAA), Indole-3-butyric acid (IBA) and Indole-3-acetic acid (IAA). Natural or synthetic plant bioregulators are organic compounds that affect the physiological processes in the plant, either to control some of these processes or to modify them.
