Gene-flow between niches facilitates local adaptation in sexual populations

, 2012
In sexual populations, gene-flow between niches is predicted to have differential consequences on local adaptation contingent upon the nature of trade-offs underlying local adaptation.

Adaptation to a seasonally varying environment: a strong latitudinal cline in reproductive diapause combined with high gene flow in Drosophila montana

, 2011
Adaptation to seasonal changes in the northern hemisphere includes an ability to predict the forthcoming cold season from gradual changes in environmental cues early enough to prepare for the harsh winter conditions. The magnitude and speed of changes in

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Pollen production and dispersion in Pinus roxburghii [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2019
Pollen dispersion and frequency of flowering were studied in the natural population of Pinus roxburghii Sargent (Chir pine) at altitudes between 1600 and 1900 m above sea level in the Tehri forest division of Garhwal Himalaya.

GENE FLOW AND GENETIC DIFFERENTIATION [PDF]

Genetics, 1974
ABSTRACT A brief analysis is presented for the effects of gene flow upon genetic differentiation within and between populations generated by mutation and drift. Previous results obtained with the "island" model are developed into a form that lends itself to biological interpretation.

Analysis of the asymmetrically expressed Ablim1 locus reveals existence of a lateral plate Nodal-independent left sided signal and an early, left-right independent role for nodal flow.

, 2010
BACKGROUND: Vertebrates show clear asymmetry in left-right (L-R) patterning of their organs and associated vasculature. During mammalian development a cilia driven leftwards flow of liquid leads to the left-sided expression of Nodal, which in turn ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

ISSR-PCR markers for assessment of genetic diversity in some Iranian and foreign grape cultivars (Vitis vinifera L.)

European Journal of Horticultural Science
With the rise in planting new grape varieties, accurate identification and ensuring plant authenticity are crucial, as mistakes can cause significant financial losses in wine and table grape production.

Evidence of gene flow between transgenic and non-transgenic maize in Colombia [PDF]

, 2015
Maize (Zea mays) is an important crop worldwide and is essential for industry. Many transgenic cultivars of maize have been developed over the years from this species, producing cultivars resistant to herbicides and insects, among other things.
