The canonical equation of adaptive dynamics for Mendelian diploids and haplo-diploids [PDF]

open access: yesInterface Focus, 2013
One of the powerful tools of adaptive dynamics is its so-called canonical equation (CE), a differential equation describing how the prevailing trait vector changes over evolutionary time. The derivation of the CE is based on two simplifying assumptions, separation of population dynamical and mutational time scales and small mutational steps.

Exploring the Role of Endophytes in Cannabis sativa L. Polyploidy and Agricultural Trait Improvement

open access: yesInternational Journal of Plant Biology
Here, we examine the effects of ploidy variation in Cannabis sativa L. cell lines on the plant host genotype-associated microbiome. The endophytic microbiome has a protocooperative role in improving plant health and productivity and represents an ...

PCR-SSCP: a method to fingerprinting sequence variability in plant gene pool using the Iranian wild diploid Triticum gene pool as a case study [PDF]

open access: yesJournal of Cell and Molecular Research, 2014
As a case study, the genotypic polymorphism of the Iranian material of diploid Triticum was screened based on internal transcribed spacer 2 (ITS2) of the ribosomal DNA (rDNA) using single strand conformation polymorphism (SSCP) analysis. This is a simple

Micronucleus occurrence in diploid and triploid rainbow trout (Oncorhynchus mykiss Walbaum)

open access: yesVeterinární Medicína, 2003
The aim of the study was to observe the influence of different ploidy levels in fish on micronucleus occur­rence. Twenty minutes after fertilization, one group of rainbow trout eggs was exposed to water temperatures of 26°C in duration of 20 minutes to ...

Effect of polyploidization on morphology in two apple (Malus × domestica) genotypes

open access: yesHorticultural Science, 2017
Because polyploidy often results in enhancement of desirable properties, artificial genome doubling is commonly used in agri- and horticultural crop breeding programs. In this study genome doubling was induced in two apple genotypes.

Diploid Alignments and Haplotyping [PDF]

open access: yes, 2015
Sequence alignments have been studied for decades under the simplified model of a consensus sequence representing a chromosome. A natural question is if there is some more accurate notion of alignment for diploid (and in general, polyploid) organisms.

Chromosome doubling can increase heat tolerance in Lonicera japonica as indicated by chlorophyll fluorescence imaging

open access: yesBiologia Plantarum, 2011
Imaging fluorometry was applied to investigate the tolerance of Japanese honeysuckle (Lonicera japonica Thunb.) of different ploidy levels to heat stress. Seedlings of L. japonica, the diploid cv. Damaohua and the tetraploid cv.
