Genetics of plate morphology in an unusual population of threespine sticklebacks (Gasterosteus aculeatus) [PDF]

open access: yes, 1976
A collection of Gasterosteus aculeatus from a single locality (Friant) in Madera County, California, contains individuals with low and high lateral plate morphology, and very few intermediates.

In vivo evidence for glycyl radical insertion into a catalytically inactive variant of pyruvate formate‐lyase

open access: yesFEBS Letters, EarlyView.
Dimeric pyruvate formate‐lyase cleaves pyruvate using a radical‐based mechanism. G734 serves as a radical storage location, and the radical is transferred to the catalytic C419 residue. Mutation of the C418‐C419 pair causes loss of enzyme activity, but does not impede radical introduction onto G734. Therefore, cis‐ but not trans‐radical transfer occurs

Genomic-inferred cross-selection methods for multi-trait improvement in a recurrent selection breeding program

open access: yesPlant Methods
The major drawback to the implementation of genomic selection in a breeding program lies in long-term decrease in additive genetic variance, which is a trade-off for rapid genetic improvement in short term.

Estimates of Genetic Variability in F2 Maize Populations [PDF]

open access: yes, 1989
Maize (Zea mays L.) breeders emphasize selection within F2 populations derived from crosses of inbred lines: Studies of the inheritance of quantitative traits in maize have been conducted primarily for generically broad-based populations.

Line × tester analysis in rapeseed: Identification of superior parents and combinations for seed yield and its components [PDF]

open access: yes, 2015
This research was carried out to investigate the genetic structure of the 20 F1s rapeseed hybrids established from five female moderate maturity lines and four early maturity male testers, to determine parents showing general combining ability (GCA) and ...

Evolutionary interplay between viruses and R‐loops

open access: yesFEBS Letters, EarlyView.
Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

Efficient Noisy Optimisation with the Sliding Window Compact Genetic Algorithm [PDF]

open access: yesarXiv, 2017
The compact genetic algorithm is an Estimation of Distribution Algorithm for binary optimisation problems. Unlike the standard Genetic Algorithm, no cross-over or mutation is involved. Instead, the compact Genetic Algorithm uses a virtual population represented as a probability distribution over the set of binary strings. At each optimisation iteration,

Quantitative inheritance of leaf shape characters in tobacco (Nicotiana tabacum L.) : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science in Plant Science at Massey University, Palmerston North, New Zealand [PDF]

open access: yes, 1982
An F₁ half diallel cross experiment with 8 parents (i.e. ½ p (p = 1) combinations) was used to study the quantitative inheritance of leaf shape characters in tobacco (Nicotiana tabacum L.).

Unlocking the potential of tumor‐derived DNA in urine for cancer detection: methodological challenges and opportunities

open access: yesMolecular Oncology, EarlyView.
Urine is a rich source of biomarkers for cancer detection. Tumor‐derived material is released into the bloodstream and transported to the urine. Urine can easily be collected from individuals, allowing non‐invasive cancer detection. This review discusses the rationale behind urine‐based cancer detection and its potential for cancer diagnostics ...
