Morella rubra, red bayberry, is an economically important fruit tree in south China. Here, we assembled the first high‐quality genome for both a female and a male individual of red bayberry. The genome size was 313‐Mb, and 90% sequences were assembled into eight pseudo chromosome molecules, with 32 493 predicted genes. By whole‐genome comparison between the female and male and association analysis with sequences of bulked and individual DNA samples from female and male, a 59‐Kb region determining female was identified and located on distal end of pseudochromosome 8, which contains abundant transposable element and seven putative genes, four of them are related to sex floral development. This 59‐Kb female‐specific region was likely to be derived from duplication and rearrangement of paralogous genes and retained non‐recombinant in the female‐specific region. Sex‐specific molecular markers developed from candidate genes co‐segregated with sex in a genetically diverse female and male germplasm. We propose sex determination follow the ZW model of female heterogamety. The genome sequence of red bayberry provides a valuable resource for plant sex chromosome evolution and also provides important insights for molecular biology, genetics and modern breeding in Myricaceae family.

Abstract: In this letter, an oxide heterostructure has been fabricated by successively growing La0.7Sr0.3MnO3 (LSMO) and BiFeO3 (BFO) layers on LaAlO3 (100) by pulsed laser deposition. Analysis of the leakage current at different temperature demonstrated that the Poole–Frenkel dominated the leakage current mechanism. Additionally, the BiFeO3/La0.7Sr0.3MnO3 heterostructure exhibits a positive colossal magnetoresistance (MR) effect over a temperature range of 50–320K. The maximum MR values are determined to be about 45.32% at H =0.5T and 28.34% at H =0.3T. At last, we report photoconductivity in BiFeO3/La0.7Sr0.3MnO3 film under illumination from 160mW/cm2 and 200mW/cm2 green-light source, and photoconductivities increase with the intensity of light enhanced.
