The de novo, chromosome-level genome assembly of the sweet chestnut (Castanea sativa Mill.) Cv. Marrone Di Chiusa Pesio.

Objectives: The sweet chestnut Castanea sativa Mill. is the only native Castanea species in Europe, and it is a tree of high economic value that provides appreciated fruits and valuable wood. In this study, we assembled a high-quality nuclear genome of the ancient Italian chestnut variety 'Marrone di Chiusa Pesio' using a combination of Oxford Nanopore Technologies long reads, whole-genome and Omni-C Illumina short reads.

Identification of a Unique Genomic Region in Sweet Chestnut ( Mill.) That Controls Resistance to Asian Chestnut Gall Wasp Yasumatsu.

The Asian chestnut gall wasp (ACGW) (Hymenoptera Yasumatsu) is a severe pest of sweet chestnut ( Mill.) with a strong impact on growth and nut production. A comparative field trial in Central Italy, including provenances from Spain, Italy, and Greece, was screened for ACGW infestation over consecutive years.

How much biodiversity is concealed in the word 'biodiversity'?

Amidst a global biodiversity crisis, the word 'biodiversity' has become indispensable for conservation and management. Yet, biodiversity is often used as a buzzword in scientific literature. Resonant titles of papers claiming to have studied 'global biodiversity' may be used to promote research focused on a few taxonomic groups, habitats, or facets of biodiversity - taxonomic, (phylo)genetic, or functional.

Gene-drive suppression of mosquito populations in large cages as a bridge between lab and field.

CRISPR-based gene-drives targeting the gene doublesex in the malaria vector Anopheles gambiae effectively suppressed the reproductive capability of mosquito populations reared in small laboratory cages. To bridge the gap between laboratory and the field, this gene-drive technology must be challenged with vector ecology.Here we report the suppressive activity of the gene-drive in age-structured An.
