1过钻头测井显示文摘越来越多的水平井钻井促使勘探与生产公司寻求更加经济高效的测井方法。这种需求促使了创新型测井技术方法的成功开发。如今,作业者利用一种独特的传送方法,使用小直径测井仪在大斜度或大位移井中获得地层评价数据。James Aivalis Benjamin W.Crouch Taylor L.Reid Gary A.Simpson 2013国外测井技术2013,,3:2
2A new classification of Cyperaceae (Poales) supported by phylogenomic data显示文摘Cyperaceae(sedges)are the third largest monocot family and are of considerable economic and ecological importance.Sedges represent an ideal model family to study evolutionary biology due to their species richness,global distribution,large discrepancies in lineage diversity,broad range of ecological preferences,and adaptations including multiple origins of C4 photosynthesis and holocentric chromosomes.Goetghebeur′s seminal work on Cyperaceae published in 1998 provided the most recent complete classification at tribal and generic level,based on a morphological study of Cyperaceae inflorescence,spikelet,flower,and embryo characters,plus anatomical and other information.Since then,several family-level molecular phylogenetic studies using Sanger sequence data have been published.Here,more than 20 years after the last comprehensive classification of the family,we present the first family-wide phylogenomic study of Cyperaceae based on targeted sequencing using the Angiosperms353 probe kit sampling 311 accessions.In addition,62 accessions available from GenBank were mined for overlapping reads and included in the phylogenomic analyses.Informed by this backbone phylogeny,a new classification for the family at the tribal,subtribal,and generic levels is proposed.The majority of previously recognized suprageneric groups are supported,and for the first time,we establish support for tribe Cryptangieae as a clade including the genus Koyamaea.We provide a taxonomic treatment including identification keys and diagnoses for the 2 subfamilies,24 tribes,and 10 subtribes,and basic information on the 95 genera.The classification includes five new subtribes in tribe Schoeneae:Anthelepidinae,Caustiinae,Gymnoschoeninae,Lepidospermatinae,and Oreobolinae.Isabel Larridon Alexandre R.Zuntini Étienne Léveillé-Bourret Russell L.Barrett Julian R.Starr AMuthama Muasya Tamara Villaverde Kenneth Bauters Grace E.Brewer Jeremy J.Bruhl Suzana M.Costa Tammy L.Elliott Niroshini Epitawalage Marcial Escudero Isabel Fairlie Paul Goetghebeur Andrew LHipp Pedro Jiménez-Mejías Izai ABSabino Kikuchi Modesto Luceño JoséIgnacio Márquez-Corro Santiago Martín-Bravo Olivier Maurin Lisa Pokorny Eric HRoalson Ilias Semmouri David A.Simpson Daniel Spalink WWayt Thomas Karen L.Wilson Martin Xanthos Félix Forest William J.Baker 2021Journal of Systematics and Evolution2021,59,4:1

4Two haplotype-resolved genomes reveal important flower traits in bigleaf hydrangea(Hydrangea macrophylla)and insights into Asterid evolution显示文摘The Hydrangea genus belongs to the Hydrangeaceae family,in the Cornales order of flowering plants,which early diverged among the Asterids,and includes several species that are commonly used ornamental plants.Of them,Hydrangea macrophylla is one of the most valuable species in the nursery trade,yet few genomic resources are available for this crop or closely related Asterid species.Two high-quality haplotype-resolved reference genomes of hydrangea cultivars‘Veitchii’and‘Endless Summer’[highest quality at 2.22 gigabase pairs(Gb),396 contigs,N5022.8 megabase pairs(Mb)]were assembled and scaffolded into the expected 18 pseudochromosomes.Utilizing the newly developed high-quality reference genomes along with high-quality genomes of other related flowering plants,nuclear data were found to support a single divergence point in the Asterids clade where both the Cornales and Ericales diverged from the euasterids.Genetic mapping with an F1 hybrid population demonstrated the power of linkage mapping combined with the new genomic resources to identify the gene for inflorescence shape,CYP78A5 located on chromosome 4,and a novel gene,BAM3 located on chromosome 17,for causing double flower.Resources developed in this study will not only help to accelerate hydrangea genetic improvement but also contribute to understanding the largest group of flowering plants,the Asterids.Xingbo Wu Sheron A.Simpson Ramey C.Youngblood Xiaofen FLiu Brian E.Scheffler Timothy A.Rinehart Lisa W.Alexander Amanda M.Hulse-Kemp 2023Horticulture Research2023,10,12:0
