Cytogenetic study of two Solenanthus Ledeb. species (Boraginaceae) in Iran [PDF]

Journal of Cell and Molecular Research, 2013
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.

Viabilidad de polen e irregularidades meióticas en una colección de stevia rebaudiana (Bertoni) Bertoni cultivada en Tucumán, Argentina [PDF]

, 2018
Stevia rebaudiana (Bertoni) Bertoni (2n=2x=22) (Asteraceae family) is a species of economic value due to the presence of steviol glycosides in leaves -mainly stevioside and rebaudioside A- which are non-caloric sugars.

Developmental regulation of an organelle tether coordinates mitochondrial remodeling in meiosis. [PDF]

, 2018
Cellular differentiation involves remodeling cellular architecture to transform one cell type to another. By investigating mitochondrial dynamics during meiotic differentiation in budding yeast, we sought to understand how organelle morphogenesis is ...

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.

Biallelic Germline Inactivation of HROB Causes Primary Gonadal Insufficiency and is Potentially Associated with Colonic Polyposis Predisposition

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The Homologous Recombination Factor With OB‐Fold (HROB) plays a role in homologous recombination and DNA replication, where it enhances the MCM8‐MCM9 helicase complex activity. Recent findings link biallelic germline HROB variants to primary gonadal insufficiency (hypergonadotropic hypogonadism), a phenotype also associated with MCM8/MCM9 ...

Cytogenetic study and pollen viability of four populations of Trigonella [PDF]

Journal of Cell and Molecular Research, 2011
In the present paper, the cytogenetic study including meiotic chromosome number and behavior along with pollen viability were performed in 4 populations of Trigonella spruneriana Boiss. This is the first cytogenetic report of the taxon.

Meiotic chromosome behavior in spread preparations of yeast. [PDF]

The Journal of cell biology, 1988
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.

A comprehensive proteome and phosphoproteome atlas across nine organs of the Chinese hamster

Animal Models and Experimental Medicine, EarlyView.
This study presents the first comprehensive proteome and phosphoproteome atlas of the Chinese hamster across nine organs (heart, liver, lung, kidney, spleen, cerebral cortex, skeletal muscle, stomach, and testis or ovary). A total of 14 219 proteins were identified in the proteome, with 11 828 phosphorylated proteins and 47 122 phosphorylation sites ...

Cytogenetics of Hypericum caprifoliatum Cham. & Schltdl. (Clusiaceae) populations and other species of the genus

Crop Breeding and Applied Biotechnology, 2008
Chromosome numbers and meiotic behavior are presented for the first time for Hypericum caprifoliatum (2n=48), H. cf carinatum (2n=48) and H. polyanthemum (2n= 32) and confirmed the H. perforatum (2n=32) number. Chromosomes are very small (ca. 1 to 2 mm).

Analysis of the transcriptional program governing meiosis and gametogenesis in yeast and mammals [PDF]

, 2006
During meiosis a competent diploid cell replicates its DNA once and then undergoes two consecutive divisions followed by haploid gamete differentiation.
