Arabidopsis mutants may represent recombinant introgression lines

BMC Research Notes, 2018
Objectives It is a common practice in Arabidopsis to transfer a mutation generated in one genetic background to other genetic background via crossing. However, the drawback of this methodology is unavoidable presence of genomic fragments from the donor ...

Recent progress in studies of the last million years of human physical and behavioural evolution Avancées récentes dans l’étude du dernier million d'années d’évolution physique et éthologique de l'espèce humaine

Journal of the Royal Anthropological Institute, EarlyView.
This article presents a synthesis of recent developments in the study of human evolution over the past five years. It begins with an overview of hominin species nomenclature and diversity, followed by an examination of the proposed population bottleneck ∼900,000 years ago.

Analysis of introgression from a tetraploid wild species, Oryza minuta, into cultivated rice, O. sativa [PDF]

, 2002
Oryza minuta, a tetraploid wild relative of cultivated rice, is an important source of resistance genes to bacterial blight (BB). Advanced backcross progenies (monosomic alien additional lines, MAALs and introgression lines) have been derived from ...

Possibilities of using the tetraploid interspecific hybrid Hordeum bulbosum L. × Hordeum vulgare L. in obtaining new recombinant barley lines

Биотехнология и селекция растений
Background. Hordeum bulbosum L. is the only wild species of the genus Hordeum, the gene pool of which is successfully used in introgressive hybridization to increase the genetic diversity of H. vulgare L.

Change of salt tolerance in common wheat after introgression of genetic material from Aegilops speltoides and Triticum timopheevii

Вавиловский журнал генетики и селекции, 2015
To improve biotic and abiotic stress tolerance in common wheat (Triticum aestivum L.), novel genotypes with genomic fragments introgressed from other cereal species are extensively developed.

Ascorbic acid disribution in three introgression lines of tomato

, 2010
Total ascorbic acid (total-AsA) content and percentage of reduced ascorbic acid (AsA) on total-AsA were investigated and discussed in fruits, leaves, petiole, stem and roots of the Solanum lycopersicum cv M82 and S. pennellii introgression lines IL7-3,

Museomics Deciphers the Phylogeographic Differentiation and Conservation Status of a Montane Pheasant

Integrative Zoology, EarlyView.
Museum specimens provide a rich source of historical DNA, enabling insights into phylogenetic relationships and demographic history of the endangered Koklass Pheasant. Our findings uncovered a previously unrecognized population in Guizhou province and highlighted elevated extinction risk in populations from Anhui province and Southern China, informing ...

Introgression of hexaploid sources of crown rot resistance into durum wheat

, 2013
Triticum turgidum ssp. durum (tetraploid durum) germplasm is very susceptible to crown rot, caused by the fungus Fusarium pseudograminearum. Screening activities to date have failed to identify even moderately susceptible lines.

Efficient QTL detection for nonhost resistance in wild lettuce: backcross inbred lines versus F2 [PDF]

, 2008
In plants, several population types [F2, recombinant inbred lines, backcross inbred lines (BILs), etc.] are used for quantitative trait locus (QTL) analyses.

Genomic Investigations Unveil the Genetic Underpinnings of Environmental Adaptation in African Goat Populations

Integrative Zoology, EarlyView.
This study integrates genomics and landscape genetics to analyze African goat environmental adaptation. Analyzing 1591 samples, it finds population structure differentiates geographically into four groups, with gene flow between wild Yura goats and North Africans.
