Traditional sugarcane cultivars (Saccharum officinarum) proved highly susceptible to diseases, and this led breeders to progress to interspecific crosses resulting in disease resistance. A backcrossing program to S. officinarum was then required to boost

Meiotic cellular rejuvenation is coupled to nuclear remodeling in budding yeast. [PDF]
Production of healthy gametes in meiosis relies on the quality control and proper distribution of both nuclear and cytoplasmic contents. Meiotic differentiation naturally eliminates age-induced cellular damage by an unknown mechanism.

Mouse versus Rat: Profound Differences in Meiotic Regulation at the Level of the Isolated Oocyte [PDF]
Cumulus cell-enclosed oocytes (CEO), denuded oocytes (DO), or dissected follicles were obtained 44–48 hr after priming immature mice (20–23 days old) with 5 IU or immature rats (25–27 days old) with 12.5 IU of equine chorionic gonadotropin, and exposed ...

Meiotic behavior of wild Caricaceae species potentially suitable for papaya improvement [PDF]
The purpose of this study was to evaluate the meiotic behavior and determine the meiotic index and pollen viability of representative plants of the wild species V. goudotiana, V. quercifolia and J. spinosa. Meiotic analysis confirmed that the species are

Chromosome numbers and meiotic behavior of some Paspalum accessions
Chromosome number and meiotic behavior were evaluated in 36 Brazilian accessions of the grass Paspalum (which had never previously been analyzed) to determinate which accessions might be useful in interspecific hybridizations.

The classification of tetraploid wheat by phylogenetic and cytogenetic analyses
Tetraploid wheat (Triticum turgidum L.) is an important species within the genus Triticum and harbors many desirable agronomic traits. The classification, origin, and evolution of tetraploid wheat remain confused and controversial, resulting in useless ...

Meiotic chromosome behavior in spread preparations of yeast. [PDF]
Chromosome behavior in meiosis is well characterized from cytological and genetic descriptions but little is known of the underlying molecular mechanisms, largely because no one experimental system has been developed to support an integrated application of modern cytological, genetic, and molecular biological methods.

Meiotic behavior of two polyploid species of genus Pleurodema (Anura: Leiuperidae) from central Argentina [PDF]
Polyploidy is an important evolutionary force but rare in vertebrates. However, in anurans, the genus Pleurodema has polyploid species, two of them tetraploid and one octoploid.

Cytogenetic study of two Solenanthus Ledeb. species (Boraginaceae) in Iran [PDF]
Chromosome number, meiotic behavior, and pollen viability were analyzed in 2 species of genus Solenanthus, S. stamineus (Desf.) Wettst. and S. circinnatus Ledeb, from Iran. This report is the first cytogenetic analysis of these species.
