Transcriptional profiles underlying parent-of-origin effects in seeds of Arabidopsis thaliana

open access: yesBMC Plant Biology, 2010
Background Crossing plants of the same species but different ploidies can have dramatic effects on seed growth, but little is known about the alterations to transcriptional programmes responsible for this.

A Phylogenetic Analysis of the Genus Fragaria (Strawberry) Using Intron-Containing Sequence from the ADH-1 Gene [PDF]

open access: yes, 2014
The genus Fragaria encompasses species at ploidy levels ranging from diploid to decaploid. The cultivated strawberry, Fragaria×ananassa, and its two immediate progenitors, F. chiloensis and F. virginiana, are octoploids.

Quantitative genetic manipulation for nauplii size reduction of Artemia franciscana Kellogg, 1906 from Indian salinas and correlated changes in the polyunsaturated fatty acids (PUFA) profile [PDF]

open access: yes, 2014
Thirteen generations of mass selection was carried out in a strain of Artemia franciscana collected from an Indian salina. The primary trait under selection was nauplii length, and the criteria of selection was small size.

Outstanding intraindividual genetic diversity in fissiparous planarians (Dugesia, Platyhelminthes) with facultative sex.

open access: yes, 2019
Predicted genetic consequences of asexuality include high intraindividual genetic diversity (i.e., the Meselson effect) and accumulation of deleterious mutations (i.e., Muller’s Ratchet), among others.

Seed evolution: parental conflicts in a multi-generational household [PDF]

open access: yes, 2017
Seeds are multi-generational structures containing a small embryonic plant enclosed in layers of diverse parental origins. The evolution of seeds was a pinnacle in an evolutionary trend towards a progressive retention of embryos and gametes within ...

Manipulation of Ploidy in Caenorhabditis elegans.

open access: yesJournal of visualized experiments : JoVE, 2018
Mechanisms that involve whole genome polyploidy play important roles in development and evolution; also, an abnormal generation of tetraploid cells has been associated with both the progression of cancer and the development of drug resistance. Until now, it has not been feasible to easily manipulate the ploidy of a multicellular animal without ...

Establishment and Optimization of an Experiment System for Flow Cytometry in Oil-Seed Camellia

open access: yesHorticulturae
Ploidy identification is a basic method for determining germplasm resources and for breeding new varieties of oil-seed camellia. In this study, flow cytometry and K-mer analysis were used to identify the ploidy of oil-seed camellia germplasms.
