Metagenomics for Bacteriology [PDF]
, 2015 The study of bacteria, or bacteriology, has gone through transformative waves since its inception in the 1600s. It all started by the visualization of bacteria using light microscopy by Antonie van Leeuwenhoek, when he first described “animalcules ...

ON THE ABUNDANCE OF POLYPLOIDS IN FLOWERING PLANTS [PDF]
Evolution, 2006 The wide distribution of polyploidy among plants has led to a variety of theories for the evolutionary advantages of polyploidy. Here we claim that the abundance of polyploidy may be the result of a simple ratcheting process that does not require evolutionary advantages due to the biological properties of organisms. The evolution of polyploidy is a one-

Citron Kinase Deficiency Leads to Chromosomal Instability and TP53-Sensitive Microcephaly [PDF]
, 2017 Mutations in citron (CIT), leading to loss or inactivation of the citron kinase protein (CITK), cause primary microcephaly in humans and rodents, associated with cytokinesis failure and apoptosis in neural progenitors.

Current Strategies of Polyploid Plant Genome Sequence Assembly
Frontiers in Plant Science, 2018 Polyploidy or duplication of an entire genome occurs in the majority of angiosperms. The understanding of polyploid genomes is important for the improvement of those crops, which humans rely on for sustenance and basic nutrition.

Roles of cell fusion, hybridization and polyploid cell formation in cancer metastasis
World Journal of Clinical Oncology, 2020 Cell-cell fusion is a normal biological process playing essential roles in organ formation and tissue differentiation, repair and regeneration. Through cell fusion somatic cells undergo rapid nuclear reprogramming and epigenetic modifications to form ...

Expression and localization of HPG axis-related genes in Carassius auratus with different ploidy
Frontiers in EndocrinologyIntroductionIn the Dongting water system, the Carassius auratus (Crucian carp) complex is characterized by the coexistence of diploid forms (2n=100, 2nCC) and polyploidy forms.

Oncogene, 2017 Our recent perplexing findings that polyploid giant cancer cells (PGCCs) acquired embryonic-like stemness and were capable of tumor initiation raised two important unanswered questions: how do PGCCs acquire such stemness, and to which stage of normal ...

Unreduced Male Gamete Formation in Cymbidium and Its Use for Developing Sexual Polyploid Cultivars
Frontiers in Plant Science, 2020 Polyploidy plays an important role in crop improvement. Polyploid plants, particularly those produced through unreduced gametes (2n gametes), show increased organ size, improved buffering capacity for deleterious mutations, and enhanced heterozygosity ...
