Autophagy-deficient breast cancer shows early tumor recurrence and escape from dormancy [PDF]
, 2018 Breast cancer patients who initially respond to cancer therapies often succumb to distant recurrence of the disease. It is not clear why people with the same type of breast cancer respond to treatments differently; some escape from dormancy and relapse ...

Escaping Constraints to Innovate: Maternal Neofunctionalization in a HoxB4 Duplicate
Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.Whole‐genome duplication in Xenopus laevis generated duplicated Hox genes that are largely constrained in sequence and developmental expression. However, HoxB4L uniquely acquired maternal expression through cis‐regulatory and protein structural divergence, illustrating how gene duplication enables transcription factors to escape pleiotropic constraints

AnimalsDistant hybridization in fish serves to integrate the genetic material from two distinct, distantly related species. In this study, we successfully produced a new hybrid fish (BG) through the intergeneric hybridization of blunt snout bream (Megalobrama ...

, 2016 Genome duplication represents a dramatic, yet relatively common, genomic change, having occurred in the evolutionary history of angiosperms, vertebrates, and yeast, among many other groups. The result of such duplications ('polyploidy,' the existence of multiple sets of chromosomes within the genome) has long been recognized and was implicated as a ...

Polyploidization in Liver Tissue
The American Journal of Pathology, 2014 Polyploidy (alias whole genome amplification) refers to organisms containing more than two basic sets of chromosomes. Polyploidy was first observed in plants more than a century ago, and it is known that such processes occur in many eukaryotes under a variety of circumstances.

Journal of the Science of Food and Agriculture, EarlyView.Abstract BACKGROUND The WX gene encodes the granule‐bound starch synthase I or waxy protein, which is the sole enzyme responsible for amylose synthesis in wheat seeds. Wild einkorn wheat (Triticum monococcum L. ssp. aegilopoides Link em. Thell.) could be an important source of variation for this gene. RESULTS This study assessed the WX gene variability

Mapping a Novel Black Spot Resistance Locus in the Climbing Rose Brite Eyes™ (‘RADbrite’)
Frontiers in Plant Science, 2018 Rose black spot, caused by Diplocarpon rosae, is one of the most devastating foliar diseases of cultivated roses (Rosa spp.). The globally distributed pathogen has the potential to cause large economic losses in the outdoor cultivation of roses ...

Transgressivity in Key Functional Traits Rather Than Phenotypic Plasticity Promotes Stress Tolerance in A Hybrid Cordgrass [PDF]
, 2019 Hybridization might promote offspring fitness via a greater tolerance to environmental stressors due to heterosis and higher levels of phenotypic plasticity.

Friends or foes? Polyploidy and competition in a grassland geophyte
Oikos, EarlyView.Previous studies have suggested polyploids may possess a competitive advantage over diploids, due to their larger size, increased vigour or ability to better respond to abiotic stress. However, few studies have tested the effect of polyploidy on competitive ability directly, and only relatively recently has this oversight begun to be addressed. Here we
