Ecotoxicological Evaluation of Organic Sunscreens Used Worldwide, Alone and in Mixture, on Terrestrial Plants

Environmental Toxicology, EarlyView.
ABSTRACT The environmental hazards of sunscreens are discussed worldwide. However, there are few ecotoxicological studies on these compounds alone for edaphic organisms, and none for their mixtures. Avobenzone (1 and 10 ng/L), octocrylene (10 and 100 μg/L), and oxybenzone (2 and 20 μg/L), alone and in binary combinations (between the lowest and the ...

Polyploidy Index and Its Implications for the Evolution of Polyploids

Frontiers in Genetics, 2019
Polyploidy has contributed to the divergence and domestication of plants; however, estimation of the relative roles that different types of polyploidy have played during evolution has been difficult.

Ultrasound features in early pregnancy for predicting abnormal karyotype in first‐trimester miscarriage

Ultrasound in Obstetrics &Gynecology, EarlyView.
ABSTRACT Objective To investigate whether combining abnormal morphological features observed on ultrasound in live pregnancies that ended in a first‐trimester miscarriage can predict an abnormal karyotype. Methods This retrospective observational cohort study was conducted at the early‐pregnancy assessment unit at University College London Hospital ...

Transcriptome of Xenopus andrei, an octoploid frog, during embryonic development

Data in Brief, 2018
Although polyploidy occurs throughout the fish and amphibian lineages, the Xenopus genus exhibits a high incidence of polyploidy, with 25 out of the 26 known species being polyploid. However, transcriptomic information is currently available for only one

Regulatory Mechanisms of Cell Polyploidy in Insects

Frontiers in Cell and Developmental Biology, 2020
Polyploidy cells undergo the endocycle to generate DNA amplification without cell division and have important biological functions in growth, development, reproduction, immune response, nutrient support, and conferring resistance to DNA damage in animals.

Multi‐omics analyses shed lights on the evolution and fruit development of Chinese raspberries (Rubus spp.)

Journal of Integrative Plant Biology, EarlyView.
High‐quality genomes of four wild raspberry species, analysis of their genetic relationships, identification of centromeres as markers for tracing their hybrid origins, exploration of fruit quality regulation, and discovery of a gene blocking anthocyanin transport and thus causing yellow fruits provides valuable resources for raspberry breeding ...

Structural variation drives rhizome innovation and adaptive divergence in sister Medicago species

Journal of Integrative Plant Biology, EarlyView.
Chromosome‐scale genome analysis, population resequencing, stress‐responsive transcriptomes and functional assays showed that coding and regulatory structural variants, especially gene duplications and noncoding presence‐absence variants, underlie rhizome formation in alpine Medicago archiducis‐nicolai and contrasting xeric adaptation in its non ...

Hidden lineages in the African Sky Islands: A taxonomic reevaluation of Afrocarduus (Compositae)

Journal of Systematics and Evolution, EarlyView.
Species delimitation is crucial for biodiversity studies. Using Hyb‐Seq and phylogenomics, we reassessed Afrocarduus, endemic to Afromontane and Afroalpine regions, uncovering 16 evolutionary lineages (2.3 Mya). Morphological data support their distinctiveness, with acaulescence evolving independently twice. The traditionally broad A.

Potential benefits of male diploidy and female triploidy for parasitoid wasps used as biological control agents: A case study in Nasonia

Biological Control
Parasitoid wasps are haplodiploid insects, but polyploidy (diploid males, triploid females) occurs for many species. In biological control, polyploidy may have beneficial effects on desirable biological related traits.
