Iron Age and Anglo-Saxon genomes from East England reveal British migration history [PDF]
, 2016 British population history has been shaped by a series of immigrations, including the early Anglo-Saxon migrations after 400 CE. It remains an open question how these events affected the genetic composition of the current British population.

FEBS Letters, EarlyView.Phototrophs evolved light‐harvesting systems adapted for efficient photon capture in habitats enriched in far‐red radiation. A subset of eukaryotic pigment‐binding proteins can absorb far‐red photons via low‐energy chlorophyll states known as red forms.

Genetic trends in the Zimbabwe’s national maize breeding program over two decades
Frontiers in Plant ScienceMonitoring genetic gains within breeding programs is a critical component for continuous improvement. While several national breeding programs in Africa have assessed genetic gain using era studies, this study is the first to use two decades of ...

Genetic variation and gain in progenies of crambe [PDF]
Crop Breeding and Applied Biotechnology, 2016 The objective of this study was to estimate the genetic variability of a Brazilian cultivar of crambe, as well as to estimate the genetic gain, with selection focusing on grain yield in crambe. Eighty two progenies were selected within the FMS Brilhante cultivar in 2009.

Rad27/FEN1 prevents accumulation of Okazaki fragments and ribosomal DNA copy number changes
FEBS Letters, EarlyView.The budding yeast Rad27 is a structure‐specific endonuclease. Here, the authors reveal that Rad27 is crucial for maintaining the stability of the ribosomal RNA gene (rDNA) region. Rad27 deficiency leads to the accumulation of Okazaki fragments and changes in rDNA copy number.

Predicted genetic gain and realised gain in stand volume of Eucalyptus globulus [PDF]
Tree Genetics & Genomes, 2012 Realised gains in stand volume of Eucalyptus globulus Labill. families at 7–9 years were compared with gains predicted at 3.5 years. Gain predictions were based on height, diameter at breast height (DBH), sectional area, and stem volume for 153 full-sib families and 18 commercial checks in five-tree line plots on three West Australian sites.

Mitochondrial fatty acid oxidation is stimulated by red light irradiation
FEBS Letters, EarlyView.Light at different wavelengths has distinct effects on keratinocyte viability and metabolism. UVA light abrogates metabolic fluxes. Blue and green light have no effect on metabolic fluxes, while red light enhanced oxidative phosphorylation by promoting fatty acid oxidation. Keratinocytes are the primary constituents of sunlight‐exposed epidermis.
