Resilience of genetic diversity in forest trees over the Quaternary

P. Milesi, C. Kastally, B. Dauphin, S. Cervantes, F. Bagnoli, K. B. Budde, S. Cavers, B. Fady, P. Faivre-Rampant, S. C. Gonzalez-Martinez, D. Grivet, F. Gugerli, V. Jorge, I. Lesur Kupin, D. I. Ojeda, , T. Pyhajarvi

The paper uses population genomic analyses to show that forest trees maintained genetic diversity despite Pleistocene climate changes.

Strong purifying selection in haploid tissue-specific genes of Scots pine supports the masking theory

S. Cervantes, R. Kesalahti, T. A. Kumpula, T. M. Mattila, H. Helantera, T. Pyhajarvi

The study tests the masking theory by comparing purifying selection in haploid and diploid tissues of Scots pine, finding stronger selection in haploid megagametophyte genes.

Does the seed fall far from the tree? Weak fine scale genetic structure in a continuous Scots pine population

A. K. Niskanen, S. T. Kujala, K. Karkkainen, O. Savolainen, T. Pyhajarvi

The paper examines fine-scale genetic structure in Scots pine, finding low average relatedness at short distances and no site differentiation.

Early acting inbreeding depression can evolve as an inbreeding avoidance mechanism

Y. J. Brandvain, L. Thomson, T. Pyhajarvi

The paper shows that inbreeding depression can be adaptive when reproductive compensation allows replacement of inviable embryos, favoring self-sacrificial recessive variants.

Utilization of tissue ploidy level variation in de novo transcriptome assembly of Pinus sylvestris

D. Ojeda, T. Mattila, T. Ruttink, S. Kujala, K. Karkkainen, J.-P. Verta, T. Pyhajarvi

This study evaluates the impact of using haploid tissue in de novo transcriptome assembly of Pinus sylvestris to reduce allelic redundancy and improve transcriptome quality.
