Genome sequences of two diploid wild relatives of cultivated sweetpotato reveal targets for genetic improvement

open access: yesNature Communications, 2018
Sweetpotato [Ipomoea batatas (L.) Lam.] is a globally important staple food crop, especially for sub-Saharan Africa. Agronomic improvement of sweetpotato has lagged behind other major food crops due to a lack of genomic and genetic resources and inherent

Scalable telomere-to-telomere assembly for diploid and polyploid genomes with double graph

open access: yesNature Methods
Despite advances in long-read sequencing technologies, constructing a near telomere-to-telomere assembly is still computationally demanding. Here we present hifiasm (UL), an efficient de novo assembly algorithm combining multiple sequencing technologies ...

A synthetic-diploid benchmark for accurate variant calling evaluation

open access: yesNature Methods, 2018
Existing benchmark datasets for use in evaluating variant-calling accuracy are constructed from a consensus of known short-variant callers, and they are thus biased toward easy regions that are accessible by these algorithms.

Agro-Morphological and Cytogenetic Characterization of Colchicine-Induced Tetraploid Plants of Polemonium caeruleum L. (Polemoniaceae)

open access: yesPlants, 2022
Polemonium caeruleum L. (Polemoniaceae) is a valuable medicinal herb with a wide spectrum of biological activities. Under natural conditions, the productivity of this species is rather low.

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.

Frequency of mononuclear diploid cardiomyocytes underlies natural variation in heart regeneration

open access: yesNature Genetics, 2017
Adult mammalian cardiomyocyte regeneration after injury is thought to be minimal. Mononuclear diploid cardiomyocytes (MNDCMs), a relatively small subpopulation in the adult heart, may account for the observed degree of regeneration, but this has not been

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 ...

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
