- The Quercus variabilis, a deciduous broadleaved tree species, holds significant ecological and economical value. While a chromosome-level genome for this species has been made available, it remains riddled with unanchored sequences and gaps. In this study, we present a nearly complete comprehensive telomere-to-telomere (T2T) and haplotype-resolved reference genome for Q. variabilis. This was achieved through the integration of ONT ultra-long reads, PacBio HiFi long reads, and Hi-C data. The resultant two haplotype genomes measure 789 Mb and 768 Mb in length, with a contig N50 of 65 Mb and 56 Mb, and were anchored to 12 allelic chromosomes. Within this T2T haplotype-resolved assembly, we predicted 36,830 and 36,370 protein-coding genes, with 95.9% and 96.0% functional annotation for each haplotype genome. The availability of the T2T and haplotype-resolved reference genome lays a solid foundation, not only for illustrating genome structure and functional genomics studies but also to inform and facilitate genetic breeding and improvement of cultivated Quercus species.

- This article documents the addition of 220 microsatellite marker loci to the Molecular Ecology Resources Database. Loci were developed for the following species: Allanblackia floribunda, Amblyraja radiata, Bactrocera cucurbitae, Brachycaudus helichrysi, Calopogonium mucunoides, Dissodactylus primitivus, Elodea canadensis, Ephydatia fluviatilis, Galapaganus howdenae howdenae, Hoplostethus atlanticus, Ischnura elegans, Larimichthys polyactis, Opheodrys vernalis, Pelteobagrus fulvidraco, Phragmidium violaceum, Pistacia vera, and Thunnus thynnus. These loci were cross-tested on the following species: Allanblackia gabonensis, Allanblackia stanerana, Neoceratitis cyanescens, Dacus ciliatus, Dacus demmerezi, Bactrocera zonata, Ceratitis capitata, Ceratitis rosa, Ceratits catoirii, Dacus punctatifrons, Ephydatia mulleri, Spongilla lacustris, Geodia cydonium, Axinella sp., Ischnura graellsii, Ischnura ramburii, Ischnura pumilio, Pistacia integerrima and Pistacia terebinthus.

- Objective: We examined the associations between maternal age at menarche and anthropometry and metabolism in adolescent offspring.Methods: Anthropometric, metabolic and blood pressure data were obtained from 304 girls and 190 boys aged 11-16 years attending school in Hangzhou (China). Age at menarche for both mothers and daughters was self-reported. Fasting blood samples were obtained and all participants underwent clinical examinations. Obesity was defined as BMI >= 95th percentile for age and sex.Results: Older maternal age at menarche was associated with older age of their daughters at menarche (r = 0.21; P < 0.001). Mother's age at menarche was not associated with anthropometry or metabolism of daughters. However, younger maternal age at menarche was associated with increased hip and waist circumferences, and BMI SDS of their sons. Boys whose mothers were <= 13 years at menarche had an adjusted relative risk of obesity 3-fold greater than sons of mothers with a later menarcheal onset (2.96; 95% CI 1.49, 5.87). Among daughters, every 1-year increase in their age at menarche was associated with a 0.34 SDS reduction in BMI. Increasing age at menarche was also associated with reduced waist and hip circumferences (-1.5 and -1.8 cm/y, respectively) and waist-to-height ratio (-0.008 per year). Girls in the youngest menarcheal age tertile (8.8-11.6 years) had diastolic blood pressure 2.2 mm Hg higher than other girls (P = 0.029).Conclusions: Younger maternal age at menarche is associated with increased obesity risk in their sons, but not daughters. However, girls who experience menarche earlier have a less favourable anthropometric profile.
