Meiotic behavior of wild Caricaceae species potentially suitable for papaya improvement
Crop Breeding and Applied Biotechnology, 2012 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

B microchromosomes in the family Curimatidae (Characiformes): mitotic and meiotic behavior. [PDF]
Comp Cytogenet, 2011 In the present work, six curimatid species were analyzed: Cyphocharax voga (Hensel, 1870), Cyphocharax spilotus (Vari, 1987), Cyphocharax saladensis (Meinken, 1933), Cyphocharax modestus (Fernández-Yépez, 1948), Steindachnerina biornata (Braga ...

Meiotic behavior and karyotypic variation in Acledra (Pentatomidae, Heteroptera).
Genetics and Molecular Research, 2010 Acledra comprises 15 taxonomically identified species, most of which are crop pests. This is the first cytogenetic study of species of this genus. Acledra kinbergii and A.

Crop Breeding and Applied Biotechnology, 2016 This study evaluated the mode of reproduction, the meiotic behavior and the pollen viability of three tetraploid plants (2n=4x=40) originated from somatic chromosome duplication of Paspalum notatum plants. The plant WKS 3 changed the mode of reproduction

Abnormal meiotic behavior in three species of Crotalaria Comportamento meiótico anormal em três espécies de Crotalaria [PDF]
Pesquisa Agropecuária Brasileira, 2009 The objective of this work was to compare the meiotic behavior and pollen grain viability of three species of Crotalaria. Slides for meiotic analysis were prepared by the air-drying technique.

Meiotic behavior of several Brazilian soybean varieties [PDF]
Genetics and Molecular Biology, 2000 Despite the importance of soybeans little cytogenetic work has traditionally been done, due to the small size and apparent similarity of the chromosomes. Fifteen soybean [Glycine max (L.) Merrill] varieties adapted for cultivation in two distinct regions

Meiotic behavior of wild, synthetic and cultivated wheats.
CYTOLOGIA, 2010 Wild relatives of bread wheat are potential sources of valuable genetic materials for wheat improvement. Genomic relationship and cross-ability between plant species can be deduced from chromosomal structure, size and behavior during meiotic division. In

ATM signaling modulates cohesin behavior in meiotic prophase and proliferating cells
Nature Structural & Molecular Biology, 2023 Cohesins are ancient and ubiquitous regulators of chromosome architecture and function, but their diverse roles and regulation remain poorly understood. During meiosis, chromosomes are reorganized as linear arrays of chromatin loops around a cohesin axis.

Reciprocal translocations: tracing their meiotic behavior [PDF]
Genetics in Medicine, 2008 Segregation and interchromosomal effect studies have been performed in reciprocal translocation carriers by sperm-fluorescent in situ hybridization reporting a great heterogeneity. The divergences have been attributed to the particular cytogenetic characteristics of each rearrangement.
