The consequences of partial clonality on the spatiotemporal genetic structure of the red alga Chondria tumulosa (Ceramiales, Rhodophyta)

Journal of Phycology, EarlyView.
Abstract The relative rates of sexual versus clonal reproduction partition genetic diversity, but the quantification of these rates remains limited in natural populations. This knowledge gap is particularly acute among tropical macroalgae. Chondria tumulosa is a red macroalga that has been documented at high abundance in the three northernmost atolls ...

Genome‐wide association study of morphometric and metabolic characteristics in European populations of the sugar kelp Saccharina latissima

Journal of Phycology, EarlyView.
Abstract The sugar kelp Saccharina latissima is a promising candidate for sustainable aquaculture in the North Atlantic and Northeast Pacific, but genetic improvement has been hindered by a limited understanding of the genetic basis of economically important traits.

Meiotic recombination takes place in the spatial context of linear elements in Schizosaccharomyces pombe [PDF]

, 2006
In fission yeast, meiotic prophase nuclei develop structures known as linear elements (LinEs), instead of a canonical synaptonemal complex. LinEs contain Rec10 protein. While Rec10 is essential for meiotic recombination, the precise role of LinEs in this

The DNA replication factor RFC1 is required for interference-sensitive meiotic crossovers in Arabidopsis thaliana.

PLoS Genetics, 2012
During meiotic recombination, induced double-strand breaks (DSBs) are processed into crossovers (COs) and non-COs (NCO); the former are required for proper chromosome segregation and fertility.

Genetic Susceptibility to Periodontitis

Journal of Periodontal Research, EarlyView.
Aim: The aim of this narrative review was to identify genes carrying risk alleles associated with an increased risk of periodontitis and to place them in a biological context. Methods: The literature was reviewed based on predefined criteria. Results: The identified genes largely fall into functions linking immune response with tissue repair. The genes

Whole‐genome duplication promotes phenotypic and genetic adaptation to elevation

New Phytologist, EarlyView.
Fitness of diploids (2x) and tetraploids (4x) of Biscutella laevigata from low (circles) and high (triangles) elevation transplanted across elevation at 585, 1236 and 1967 m above sea level. Summary Whole‐genome duplication (WGD) is often considered as either an adaptive dead‐end or a facilitator of rapid adaptation under changing environments.

Tackling Plant Meiosis: From Model Research to Crop Improvement

Frontiers in Plant Science, 2018
Genetic engineering and traditional plant breeding, which harnesses the natural genetic variation that arises during meiosis, will have key roles to improve crop varieties and thus deliver Food Security in the future. Meiosis, a specialized cell division

A Repertoire of Major Genes From Crop Wild Relatives for Breeding Disease‐Resistant Wheat, Rice, Maize, Soybean and Cotton Crops

Plant Breeding, EarlyView.
ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.

Impact of histone H4K16 acetylation on the meiotic recombination checkpoint in Saccharomyces cerevisiae [PDF]

, 2016
In meiotic cells, the pachytene checkpoint or meiotic recombination checkpoint is a surveillance mechanism that monitors critical processes, such as recombination and chromosome synapsis, which are essential for proper distribution of chromosomes to the ...
