Genetic diversity of Poa pratensis L. depending on geographical origin and compared with genetic markers
BACKGROUND Poa pratensis is one of the most common species of meadow grass in Europe. Most cultivars of the species found in Poland were originally derived from its ecotypes. We compared the effectiveness of the RAPD and ISSR methods in assessing the genetic diversity of the selected populations of P. pratensis. We examined whether these methods could be useful for detecting a possible link bet...
متن کاملApplication of DNA Molecular Markers in Plant Breeding (Review article)
Plant Breeding has utilized a wide range of techniques and methods to improve the quality and quantity of plants. The molecular markers are the tools that have provided a new perspective for plant breeding advancements. This article has reviewed the various advantages and uses of molecular markers and the utilization of the high potential of natural polymorphisms within communities, combined wi...
متن کاملSERK and APOSTART. Candidate genes for apomixis in Poa pratensis.
Seed production generally requires the mating of opposite sex gametes. Apomixis, an asexual mode of reproduction, avoids both meiotic reduction and egg fertilization. The essential feature of apomixis is that an embryo is formed autonomously by parthenogenesis from an unreduced egg of an embryo sac generated through apomeiosis. If apomixis were well understood and harnessed, it could be exploit...
متن کاملSelection of Candidate Reference Genes for Gene Expression Analysis in Kentucky Bluegrass (Poa pratensis L.) under Abiotic Stress
Kentucky bluegrass (Poa pratensis L.) belong to Gramineae and is widely used in lawns, golf courses, landscapes, and sport fields as a prominent cool-season grass. Gene expression patterns during different stages of plant development can provide clues toward the understanding of its biological functions. The selection and validation of reference genes are the first steps in any real-time quanti...
متن کاملمطالعه واکنش های مورفولوژیکی، فیزیولوژیکی و بیوشیمیایی چمن Poa pratensis L. رقم ‘Barimpala’ تحت تنش خشکی
تنش خشکی یکی از مهم ترین عواملی است که رشد و کیفیت چمن را کاهش می دهد. به منظور مطالعه واکنش های چمن Poa pratensis رقم ‘Barimpala’ تحت دوره های زمانی تنش خشکی، بذور این چمن در گلدان های استوانه ایی به طول 60 سانتی متر و به قطر 15 سانتی متر در فضای آزاد کاشت شدند و آبیاری به نحوی انجام شد که آب به آرامی از انتهای زهکش گلدان خارج شود. پس از استقرار کامل گیاهان، آبیاری قطع گردید تا بیشتر گلدان ها ...
