polyRAD: Genotype Calling with Uncertainty from Sequencing Data in Polyploids and Diploids

G3: Genes, Genomes, Genetics, 2018
Low or uneven read depth is a common limitation of genotyping-by-sequencing (GBS) and restriction site-associated DNA sequencing (RAD-seq), resulting in high missing data rates, heterozygotes miscalled as homozygotes, and uncertainty of allele copy ...

NGS Based Haplotype Assembly Using Matrix Completion

, 2019
We apply matrix completion methods for haplotype assembly from NGS reads to develop the new HapSVT, HapNuc, and HapOPT algorithms. This is performed by applying a mathematical model to convert the reads to an incomplete matrix and estimating unknown ...

Chromatin Topology Reconfiguration Orchestrates Thermotolerant Male Fertility via GhAL5 in Cotton

Advanced Science, EarlyView.
This study investigates cotton’s high‐temperature (HT) response using multi‑omics. Dynamic 3D genome changes drive expression bias affecting male fertility. The tolerant line shows controlled chromatin dynamics, while the sensitive line exhibits overactivation.

Occurrence of spontaneous polyploids in Citrus

Horticultural Science, 2006
Seedlings recovered from underdeveloped seeds of different commercial cultivars of Citrus were studied for their ploidy level. Cytological examination revealed that maximum triploid plants were found in lime Kaghzi (15.5%) followed by grapefruit Foster ...

Estimating Effective Number of Breeders Under the Heterozygote-Excess Equilibrium. [PDF]

Mol Ecol Resour
ABSTRACT Estimating the effective number of breeders per reproductive cycle or cohort (Nb$$ {N}_b $$) can contribute to understanding the viability of wild populations. However, previous Nb$$ {N}_b $$ estimators based on heterozygote‐excess assume that parental genotypes are in accordance with Hardy–Weinberg equilibrium (HWE), and can only be applied ...

Occurrence of LINE, gypsy-like, and copia-like retrotransposons in the clonally propagated sweet potato (Ipomoea batatas L.) [PDF]

, 2011
Retrotransposons are a class of transposable elements that represent a major fraction of the repetitive DNA of most eukaryotes. Their abundance stems from their expansive replication strategies.

MicroRNA‐375‐3p Targets Fatty Acid Synthase and Relish to Regulate Energy Allocation During Pupal Metamorphosis and Starvation

Advanced Science, EarlyView.
During pupal metamorphosis and starvation, elevated 20‐hydroxyecdysone (20E) and suppressed insulin trigger Forkhead box O (FOXO) nuclear translocation, enhancing miR‐375‐3p expression. This downregulates fatty acid synthase (FASN) and Relish, promoting lipid breakdown for energy while prioritizing antioxidant responses over immune functions to support

Chickens First\ud \ud Speciation by “Hopeful Monsters” in Fraternal Supertwins\ud [PDF]

, 2008
The idea of “hopeful monster” was proposed by Goldschmidt who envisioned that speciation could occur instantaneously via major chromosomal rearrangement in a one-step process; but he could not unravel how similar individual in the opposite sex to appear ...
