Using immunofluorescence techniques to analyze ejaculate-derived spermatocytes from subfertile men provides a novel technique for examining meiosis without the need for a testicular biopsy.Previous article in issue Next article in issue Key Words Meiotic recombination sex body association Robertsonian ...
fertilization to be reproductive the single cells they produce must grow into new multicellular organisms. Since in embryophytic plants both the zygotes made through fertilization and the spores made by meiosis typically have this ability, both their fertilization and meiosis will be considered to be ...

What events mark the beginning and the end of the first stage of interphase? What happens within the cell during this stage? The Cell Cycle: Interphase, Mitosis, and Cytokinesis The items to those in the key. Answers can be used more than once or not at all. Key: a. G1 phase of in...
Many recent advances have emerged in the telomere and telomerase fields. This Timeline article highlights the key advances that have expanded our views on the mechanistic underpinnings of telomeres and telomerase and their roles in ageing and disease. Th
We also utilize long-read sequencing to characterize the msg and kexin gene families, and perform biochemical analysis of the key cell wall components chitin and mannan, to experimentally validate genome predictions. We present the major differences in genome content and functional attributes of ...
Vacuolar invertase is one of the key enzymes in sucrose metabolism that irreversibly catalyzes the hydrolysis of sucrose to glucose and fructose in plants. In this research, three vacuolar invertase genes, named MeVINV1-3, and with 653, ... Yao,Yuan,Wu,... 被引量: 3发表: 2014年 Oviposit...
highlighting in particular essential differences in cellular structures and processes between phyla. We focus on key dissimilarities in cellular organization, e.g. regarding cell size and shape, the composition of the extracellular matrix, the types of cell–cell junctions, the presence of specific mem...
11i). These results indicated that the ETX-embryoids recapitulate key events of uterine implantation, such as discrete decidualization, vascular anastomosis, patterned Dtprp expression in the decidua, and clearance of uterine luminal epithelium. Fig. 7 Implantation initiation of the ETX-embryoids. a ...
[14], our experimental results suggest that inC. grandis, at least three key factors: Gynoecium Suppressor, Stamen Promoting Factor And Male Fertility Factor have assembled and possibly rearranged during evolution of the Y chromosome. However, development of the stamen with sterile pollens in GyM-...
