| 1 | Phased,chromosome-scale genome assemblies of tetraploid potato reveal a complex genome,transcriptome,and predicted proteome landscape underpinning genetic diversity显示文摘Cultivated potato is a clonally propagated autotetraploid species with a highly heterogeneous genome.Phased assemblies of six cultivars including two chromosome-scale phased genome assemblies revealed extensive allelic diversity,including altered coding and transcript sequences,preferential allele expression,and structural variation that collectively result in a highly complex transcriptome and predicted proteome,which are distributed across the homologous chromosomes.Wild species contribute to the extensive allelic diversity in tetraploid cultivars,demonstrating ancestral introgressions predating modern breeding efforts.As a clonally propagated autotetraploid that undergoes limited meiosis,dysfunctional and deleterious alleles are not purged in tetraploid potato.Nearly a quarter of the loci bore mutations are predicted to have a high negative impact on protein function,complicating breeder’s efforts to reduce genetic load.The StCDF1 locus controls maturity,and analysis of six tetraploid genomes revealed that 12 allelic variants of StCDF1 are correlated with maturity in a dosage-dependent manner.Knowledge of the complexity of the tetraploid potato genome with its rampant structural variation and embedded deleterious and dysfunctional alleles will be key not only to implementing precision breeding of tetraploid cultivars but also to the construction of homozygous,diploid potato germplasm containing favorable alleles to capitalize on heterosis in F1 hybrids. | Genevieve Hoopes Xiaoxi Meng John P.Hamilton Sai Reddy Achakkagari Fernanda de Alves Freitas Guesdes Marie E.Bolger Joseph J.Coombs Danny Esselink Natalie R.Kaiser Linda Kodde Maria Kyriakidou Brian Lavrijssen Natascha van Lieshout Rachel Shereda Heather K.Tuttle Brieanne Vaillancourt Joshua C.Wood Jan Mde Boer Nolan Bornowski Peter Bourke David Douches Herman Jvan Eck Dave Ellis Max J.Feldman Kyle M.Gardner Johannes C.P.Hopman Jiming Jiang Walter S.De Jong Joseph C.Kuhl Richard G.Novy Stan Oome Vidyasagar Sathuvalli Ek Han Tan Remco A.Ursum M.Isabel Vales Kelly Vining Richard G.F.Visser Jack Vossen G.Craig Yencho Noelle L.Anglin Christian W.B.Bachem Jeffrey B.Endelman Laura M.Shannon Martina V.Stromvik Helen H.Tai Bjorn Usadel C.Robin Buell Richard Finkers | 2022 | Molecular Plant2022，15，3： | 4 |
| 2 | Electrically pumped quantum-dot lasersgrownon 300 mm patterned Si photonic wafers显示文摘Monolithic integration of quantum dot(QD)gain materials onto Si photonic platforms via direct epitaxial growth is a promising solution for on-chip light sources.Recent developments have demonstrated superior device reliability in blanket hetero-epitaxy ofⅡ-Ⅴdevices on Si at elevated temperatures.Yet,thick,defect management epi designs prevent vertical light coupling from the gain region to the Si-on-lnsulator waveguides.Here,we demonstrate the frst electrically pumped QD lasers grown by molecular beam epitaxy on a 300 mm patterned(001)Si wafer with a buttcoupled configuration.Unique growth and fabrication challenges imposed by the template architecture have been resolved,contributing to continuous wave lasing to 60℃and a maximum double-side output power of 126.6 mW at 20℃with a double-side wall-plug efficiency of 8.6%.The potential for robust on-chip laser operation and effcient lowloss light coupling to Si photonic circuits makes this heteroepitaxial integration platform on Si promising for scalable and low-cost mass production. | Chen Shang Kaiyin Feng Eamonn THughes Andrew Clark Mukul Debnath Rosalyn Koscica Gerald Leake Joshua Herman David Harame Peter Ludewig Yating Wan John E.Bowers | 2022 | Light(Science & Applications)2022，11，11： | 1 |
