Simple sequence repeat DNA markers in alfalfa and perennial and annual Medicago species.
Simple sequence repeat (SSR) or microsatellite DNA markers have been shown to function well in plant and mammalian species for genetic map construction and genotype identification. The objectives of the work reported here were to search GenBank for the presence of SSR-containing sequences from the genus Medicago, to assess the presence and frequency of SSR DNA in the alfalfa (Medicago sativa (L...
متن کاملSuperresolution imaging reveals structurally distinct periodic patterns of chromatin along pachytene chromosomes.
During meiosis, homologous chromosomes associate to form the synaptonemal complex (SC), a structure essential for fertility. Information about the epigenetic features of chromatin within this structure at the level of superresolution microscopy is largely lacking. We combined single-molecule localization microscopy (SMLM) with quantitative analytical methods to describe the epigenetic landscape...
متن کاملThe Effect of Fast Neutrons on Chromosomes in Meiosis and Its Bearing upon Pachytene Pairing.
REVIOUS experiments have shown that quantitatively the response P of chromosomes of Vicia faba in pachytene to X-rays is approximately the same as that of the same species at the onset of the somatic prophase (MARSHAK 1939a). CREIGHTON (1941) using methods similar to those employed in the Vicia studies found that meiotic chromosomes are only a sixth as sensitive as the mitotic chromosomes in Ch...
متن کاملMapping pachytene chromosomes of coffee using a modified protocol for fluorescence in situ hybridization
Fluorescence in situ hybridization (FISH) is the most direct method for physically mapping DNA sequences on chromosomes. Fluorescence in situ hybridization mapping of meiotic chromosomes during the pachytene stage is an important tool in plant cytogenetics, because it provides high-resolution measurements of physical distances. Fluorescence in situ hybridization mapping of coffee pachytene chro...
متن کاملChromosome micro-dissection and region-specific libraries from pachytene chromosomes of maize (Zea mays L.)
For the first time, pachytene chromosomes have been used for micro-dissection, amplification and cloning using the short arm of maize chromosome 6. For this purpose, methods for the preparation of unstained pachytene chromosomes were developed. In two separate experiments, 10 and 12 segments of the satellite region were isolated utilizing glass needles and DNA was amplified by linkeradaptor-PCR...
