Transcriptome Sequence Reveals Candidate Genes Involving in the Post-Harvest Hardening of Trifoliate Yam .

Storage ability of trifoliate yam () is restricted by a severe post-harvest hardening (PHH) phenomenon, which starts within the first 24 h after harvest and renders tubers inedible. Previous work has only focused on the biochemical changes affecting PHH in . To the best of our knowledge, the candidate genes responsible for the hardening of have not been identified.

Comparative Phylogeography of and (Plantaginaceae) Across Europe: Integrating Hybridization and Polyploidy in Phylogeography.

Climatic fluctuations in the Pleistocene caused glacial expansion-contraction cycles in Eurasia and other parts of the world. Consequences of these cycles, such as population expansion and subsequent subdivision, have been studied in many taxa at intraspecific population level across much of the Northern Hemisphere. However, the consequences for the potential of hybridization and polyploidization are poorly understood.

Genetic diversity and population structure of trifoliate yam (Dioscorea dumetorum Kunth) in Cameroon revealed by genotyping-by-sequencing (GBS).

Background: Yams (Dioscorea spp.) are economically important food for millions of people in the humid and sub-humid tropics. Dioscorea dumetorum (Kunth) is the most nutritious among the eight-yam species, commonly grown and consumed in West and Central Africa.

Transcriptomic resources and marker validation for diploid and polyploid (Plantaginaceae) from New Zealand and Europe.

Premise Of The Study: Polyploidy may generate novel variation, leading to adaptation and species diversification. An excellent natural system to study polyploid evolution in a comparative framework is (Plantaginaceae), which comprises several parallel, recently evolved polyploid series.

Methods: Over 105 million Illumina paired-end sequence reads were generated from cDNA libraries of leaf tissue from eight individuals representing three European and four New Zealand species.

Characterization of 12 polymorphic SSR markers in Veronica subsect. Pentasepalae (Plantaginaceae) and cross-amplification in 10 other subgenera.

Premise Of The Study: Microsatellite primers were developed in the perennial herbs of the diploid-polyploid complex Veronica subsect. Pentasepalae (Plantaginaceae) to investigate the role that hybridization has played in the evolution of the group, which includes several endangered species.

Methods And Results: Twelve pairs of primers leading to polymorphic and readable markers were identified and optimized from V.

Supratidal Extremophiles--Cyanobacterial Diversity in the Rock Pools of the Croatian Adria.

Hardly any molecular studies have been done on euendoliths of marine coastal environments, especially along the supratidal ranges of carbonate coasts. In our study, we provide a comparative sequence analysis using 454 pyrosequencing of the 16S ribosomal RNA (rRNA) gene combined with extensive microscopy of the endolithic community from rock pools of the Croatian Adria. Molecular diversity indices and richness estimates showed high level of diversity, particularly in high-salinity samples.
