Meiotic behavior of wild Caricaceae species potentially suitable for papaya improvement [PDF]
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

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

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 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. modesta showed the modal number of the Pentatomidae (2n = 14 = 12 + XY), while A.

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.

Meiotic analysis of interspecific hybrids between Capsicum frutescens and Capsicum chinense [PDF]
Crop Breeding and Applied Biotechnology, 2017 The aim of this study was to observe the genetic relationship between C. frutescens (UENF 1636) and C. chinense (UENF 1785) based on the meiotic behavior, on the meiotic index, and on pollen viability of their F1 hybrids. For meiotic analysis and meiotic
