Whole-genome sequencing reveals forgotten lineages and recurrent hybridizations within the kelp genus Alaria (Phaeophyceae).

The genomic era continues to revolutionize our understanding of the evolution of biodiversity. In phycology, emphasis remains on assembling nuclear and organellar genomes, leaving the full potential of genomic datasets to answer long-standing questions about the evolution of biodiversity largely unexplored. Here, we used whole-genome sequencing (WGS) datasets to survey species diversity in the kelp genus Alaria, compare phylogenetic signals across organellar and nuclear genomes, and specifically test whether phylogenies behave like trees or networks.

Genetic toolkits of the red alga Pyropia tenera against the three most common diseases in Pyropia farms.

Disease outbreaks devastate Pyropia aquaculture farms every year. The three most common and serious diseases are Olpidiopsis-blight and red-rot disease caused by oomycete pathogens and green-spot disease caused by the PyroV1 virus. We hypothesized that a basic genetic profile of molecular defenses will be revealed by comparing and analyzing the genetic response of Pyropia tenera against the above three pathogens.

[Changes of infection of the prostate tissue by Herpesviridae family viruses and HPV in prostate cancer patients depending on the stage of the pathological process].

The role of infection in the beginning and progression of prostate cancer is not known to the end at the moment. Experimental data, presented in the article, are obtained by hybridization in situ and demonstrate high degree of infection of the prostate tissue by viruses with the oncogenic and oncomodulation properties HCMV, EBV, HHV8 and HPV. The authors revealed that in patients at different substages of T2 stage infection of the prostate tissue increased from T2a to T2c.

Identification of three proteins involved in fertilization and parthenogenetic development of a brown alga, Scytosiphon lomentaria.

Metabolic pathways of cell organelles may influence the expression of nuclear genes involved in fertilization and subsequent zygote development through a retrograde regulation. In Scytosiphon lomentaria, inheritance of chloroplast is biparental but mitochondria are maternally inherited. Male and female gametes underwent different parthenogenetic outcomes.

Isolation and characterization of a sex-specific lectin in a marine red alga, Aglaothamnion oosumiense Itono.

In red algae, spermatial binding to female trichogynes is mediated by a lectin-carbohydrate complementary system. Aglaothamnion oosumiense is a microscopic filamentous red alga. The gamete recognition and binding occur at the surface of the hairlike trichogyne on the female carpogonium.
