Using genotyping-by-sequencing to understand Musa diversity : [P449] [PDF]

open access: yes, 2014
This project is part of a larger effort to apply genomics technologies to assess genetic diversity and to advance genetic improvement efforts in Musa (banana and plantain), a major staple food crop in the developing world.

Circulating tumor DNA (ctDNA) trajectories predict survival in trifluridine/tipiracil‐treated metastatic colorectal cancer patients

open access: yesMolecular Oncology, EarlyView.
The authors applied joint/mixed models that predict mortality of trifluridine/tipiracil‐treated metastatic colorectal cancer patients based on circulating tumor DNA (ctDNA) trajectories. Patients at high risk of death could be spared aggressive therapy with the prospect of a higher quality of life in their remaining lifetime, whereas patients with a ...

Genetic evaluation of Ethiopian Boran cattle and their crosses with Holstein Friesian in central Ethiopia: milk production traits

open access: yesAnimal, 2009
Breed additive and non-additive effects, and genetic parameters of lactation milk yield (LYD), 305-day milk yield (305YD), lactation length (LL), milk yield per day of lactation (DM) and lifetime milk yield (LTYD) were estimated in Ethiopian Boran cattle

Identification of potential soybean crosses for grain yield in the F2 generation

open access: yesAgrarian, 2019
The diallel schemes comprise a powerful strategy for the genetic study of the characters and the ability to match the parents, as well as to obtain information at the different stages of a genetic breeding program involving artificial hybridizations.

A cytological demonstration of "genetic" crossing-over [PDF]

open access: yesProceedings of the Royal Society of London. Series B, Containing Papers of a Biological Character, 1930
A stage in meiosis where the paired chromosomes form loops, coming together at points distributed at random along their length, was first described by Rückert (1892) inPristiurus. These points we now recognise in suitable material as exchanges of partner amongst the four pairing half-chromosomes.

Selective breeding program for genetic improvement of Macrobrachium rosenbergii in Thailand. [PDF]

open access: yes, 2005
Although the giant freshwater prawn (Macrobrachium rosenbergii) has been domesticated in Thailand for over decades, appropriate selective breeding program has yet to be achieved. Good quality seeds for the Machrobrachium aquaculture industry is therefore

Chromosomal anchoring of linkage groups and identification of wing size QTL using markers and FISH probes derived from microdissected chromosomes in Nasonia(Pteromalidae : Hymenoptera) [PDF]

open access: yes, 2004
Nasonia vitripennis is a small parasitic hymenopteran with a 50-year history of genetic work including linkage mapping with mutant and molecular markers. For the first time we are now able to anchor linkage groups to specific chromosomes.

Addressing persistent challenges in digital image analysis of cancer tissue: resources developed from a hackathon

open access: yesMolecular Oncology, EarlyView.
Large multidimensional digital images of cancer tissue are becoming prolific, but many challenges exist to automatically extract relevant information from them using computational tools. We describe publicly available resources that have been developed jointly by expert and non‐expert computational biologists working together during a virtual hackathon

Genetic variability in popcorn synthetic population

open access: yesActa Scientiarum: Agronomy, 2018
The Brazilian popcorn has low genetic variability and the successful development of advanced lines, new popcorn cultivars with high grain yield (GY) and expansion volume (PE) is dependent on parental selection and precise determination of heterotic ...
