东方蜜蜂微孢子虫N6-腺苷特异性甲基化转移酶基因的克隆、分子特性及表达模式北大核心

【目的】东方蜜蜂微孢子虫(Nosme ceranae)专性侵染成年蜜蜂导致微孢子虫病,给养蜂生产造成很大损失。目前,东方蜜蜂微孢子虫的N6-腺苷特异性甲基化转移酶(N6-adenine-specific methyltransferase,N6AMT)基因NcN6AMT的研究仍然缺失。本研究对NcN6AMT的编码序列(coding sequence,CDS)区进行克隆,并解析NcN6AMT蛋白的理化性质和分子特性,进而测定东方蜜蜂微孢子虫侵染意大利蜜蜂(Apis mellifera ligustica)和中华蜜蜂(Apis cerana cerana)工蜂过程中NcN6AMT的相对表达量,以期丰富NcN6AMT的信息,并为探究东方蜜蜂微孢子虫侵染过程NcN6AMT的功能及表观调控机制提供基础。【方法】采用Protparam和ProtScale软件对NcN6AMT进行等电点和亲水性分析。通过SignalP 5.0、NetPhos 3.1、TMHMM-2.0、SOPMA和SWISS-MODEL等软件分别预测NcN6AMT的信号肽、磷酸化位点、跨膜结构域、二级结构和三级结构。使用WoLF PSORT II软件预测NcN6AMT的亚细胞定位。根据N6AMT氨基酸序列,通过TBtools软件对智人(Homo sapiens)、小鼠(Mus musculus)、褐飞虱(Nilaparvata lugens)、兔脑炎微孢子虫(Encephalitozoon cuniculi)、肠脑炎微孢子虫(Encephalitozoon intestinalis ATCC 50506)、蚱蜢脑炎微孢子虫(Encephalitozoon romaleae SJ-2008)、美洲思普雷格孢虫(Spraguea lophii 42_110)、家蚕微孢子虫(Nosema bombycis CQ1)、隐生菱形藻(Nitzschia inconspicua)和东方蜜蜂微孢子虫(Nosema ceranae)的N6AMT进行结构域预测和分析。利用MEME软件和MEGA 11.0软件进行东方蜜蜂微孢子虫和其他物种N6AMT的保守基序预测及进化树构建。采用实时荧光定量聚合酶链式反应(real-time fluorescence quantitative polymerase chain reaction,RT-qPCR)检测NcN6AMT在东方蜜蜂微孢子虫侵染意大利蜜蜂和中华蜜蜂工蜂过程的相对表达量。【结果】通过PCR扩增出大小约500 bp的目的片段,克隆测序结果显示其与GenBank数据库收录的预测序列一致;NcN6AMT蛋白的分子量约为18.7 kDa,分子式为C845H1374N214O249S6,理论等电点为5.88,脂溶系数是119.76,不稳定系数为37.47,平均亲水系数为0.025,含166个氨基酸和15个磷酸化位点,不含典型的跨膜结构域和信号肽,可同时定位于细胞质、线粒体、细胞核和液泡膜;NcN6AMT含1个甲基转移酶小结构域(methyltransferase small domain,MTS),该结构域同样存在于家蚕微孢子虫和兔脑炎微孢子虫等8个其他物种的N6AMT;在东方蜜蜂微孢子虫、兔脑炎微孢子虫、肠脑炎微孢子虫和蚱蜢脑炎微孢子虫的N6AMT中均预测到5个相同的保守基序;NcN6AMT与家蚕微孢子虫、肠脑炎微孢子虫、兔脑炎微孢子虫和蚱蜢脑炎微孢子虫的N6AMT序列一致性达到70.92%;东方蜜蜂微孢子虫和家蚕微孢子虫的N6AMT在系统进化树上聚为一支;东方蜜蜂微孢子虫接种后1–4 d,NcN6AMT在意大利蜜蜂和中华蜜蜂工蜂中肠内均呈现先上升后下降的表达趋势。【结论】成功克隆到NcN6AMT基因的CDS区,明确了NcN6AMT蛋白的理化性质和分子特性,并揭示东方蜜蜂微孢子虫和家蚕微孢子虫的N6AMT蛋白具有较高的保守性,NcN6AMT在东方蜜蜂微孢子虫侵染意大利蜜蜂和中华蜜蜂工蜂的第一个增殖周期(1–4 dpi)内动态表达且均呈上升-下降的表达模式。     

Therps16 intron and the phylogeny of theRubioideae (Rubiaceae)

The phylogeny of the subfamilyRubioideae (Rubiaceae) was estimated from sequence variation in therps16 intron (cpDNA) in 143 ingroup and 5 outgroup taxa. The analysis largely confirms a recent one based onrbcL sequences, but branch support is often much stronger. Three of the traditional subfamilies are supported,Rubioideae, Cinchonoideae s. str., andIxoroideae s. l. while there is no support forAntirheoideae. TheRubioideae are the sister group of all otherRubiaceae and comprise the tribesAnthospermeae, Coccocypseleae, Cruckshanksieae, Coussareeae, Gaertnereae, Hedyotideae, Knoxieae, Morindeae, Ophiorrhizeae, Paederieae, Pauridiantheae, Perameae, Psychotrieae, Rubieae, Spermacoceae, Theligoneae, andUrophylleae. TheHamelieae andHillieae belong to theCinchonoideae. Rachicallis andSiemensia should be transferred from theHedyotideae to theCinchonoideae. ThePauridiantheae, Urophylleae, Ophiorrhizeae, andRaritebe form the basalmost subclade of theRubioideae. The second basalmost clade consists of the generaLasianthus andPerama. The third basalmost clade consists of the tribesCoussareeae, Coccocypseleae andCruckshanksieae, and the generaDeclieuxia andHindsia. The tribesKnoxieae, Anthospermeae, Argostemmateae, Paederieae, Theligoneae, Rubieae, Hedyotideae, andSpermacoceae are members of one clade. TheKnoxieae are monophyletic ifOtiophora, Otomeria, andPentas are included. The tribeAnthospermeae is supported as monophyletic, but its subtribes are not. ThePaederieae, together withTheligonum, form a paraphyletic grade basal to theRubieae. TheHedyotideae, includingSchismatoclada, form a grade at the base of theSpermacoceae. TheGaertnereae are monophyletic and distinct from thePsychotrieae. TheMorindeae are monophyletic and includeDamnacanthus andMitchella. Schradera is the sister group of theMorindeae. ThePsychotrieae are monophyletic when theGaertnereae, Lasianthus, andDeclieuxia are excluded. The recognition of a subtribeHydnophytineae leaves the rest of thePsychotrieae paraphyletic.Psychotria is paraphyletic with respect to all other genera of the tribe. Approximately 50 genera are here classified for the first time based on molecular data.     

Species boundaries and interrelationships of two closely related sympatric diploid wild potato species, Solanum astleyi and S. boliviense, based on RAPDs

 The more than 200 wild and cultivated species relatives of potato (Solanum sect. Petota) present a valuable germplasm base for cultivar improvement. However, species boundaries and interrelationships within sect. Petota are controversial, inhibiting the efficient organization of the many germplasm collections of these species. One controversy involves questions of species boundaries and interrelationships of S. astleyi and S. boliviense. Solanum boliviense is narrowly endemic to two Departments in southern Bolivia, and S. astleyi is known only from one site entirely within the range of this species, where they co-occur. Both species are diploid and morphologically very similar. Artificial hybrids between them are fully fertile, and the species putatively hybridize naturally. These data have been interpreted to designate them as separate species or as S. astleyi an ecotype of S. boliviense. Putative progenitors of S. astleyi are S. boliviense, S. megistacrolobum subsp. megistacrolobum, and S. megistacrolobum subsp. toralapanum. We evaluated interrelationships among these species with random amplified polymorphic DNA’s (RAPDs) generated for 2 accessions of S. astleyi and 14 accessions of S. boliviense. These represent the entire geographic range of the former species and nearly the entire range of the latter. We also analyzed 1 accession each of S. acaule subsp. acaule, S. acaule subsp. aemulans, S. albicans, S. berthaultii, S. megistacrolobum subsp. megistacrolobum, S. megistacrolobum subsp. toralapanum, S. raphanifolium, S. sogarandinum, and S. sparsipilum. Phenetic analyses of the RAPD data show S. astleyi and S. boliviense to form two distinct groups and to be more similar to each other than to any of the other species investigated, suggesting that S. astleyi and S. boliviense are sister taxa. The divergence of S. astleyi and S. boliviense relative to other species examined suggests that they are worthy of taxonomic recognition at the subspecies, rather than species level, and we propose the new combination S. boliviense subsp. astleyi.

PHYLOGENY OF THE EUGLENALES INFERRED FROM PLASTID LSU rDNA SEQUENCES1

To gain insights into the phylogeny of the Euglenales, we analyzed the plastid LSU rDNA sequences from 101 strains of the photosynthetic euglenoids belonging to nine ingroup genera (Euglena, Trachelomonas, Strombomonas, Monomorphina, Cryptoglena, Colacium, Discoplastis, Phacus, and Lepocinclis) and two outgroup genera (Eutreptia and Eutreptiella). Bayesian and maximum‐likelihood (ML) analyses resulted in trees of similar topologies and four major clades: a Phacus and Lepocinclis clade; a Colacium clade; a Trachelomonas, Strombomonas, Monomorphina, and Cryptoglena clade; and a Euglena clade. The Phacus and Lepocinclis clade was the sister group of all other euglenalian genera, followed by Discoplastis spathirhyncha (Skuja) Triemer and the Colacium clade, respectively, which was inconsistent with their placement based on nuclear rDNA genes. The Trachelomonas, Strombomonas, Monomorphina, and Cryptoglena clade was sister to the Euglena clade. The loricate genera, Trachelomonas and Strombomonas, were closely related to each other, while Monomorphina and Cryptoglena also grouped together. The Euglena clade formed a monophyletic lineage comprising most species from taxa formerly allocated to the subgenera Calliglena and Euglena. However, within this genus, none of the subgenera was monophyletic.     

Correspondence of environmental tolerances with leaf and branch attributes for six co-occurring species of broadleaf evergreen trees in northern California

 For the angiosperm dominants of northern California’s mixed evergreen forests, this study compares the display of photosynthetic tissue within leaves and along branches, and examines the correspondence between these morphological attributes and the known environmental tolerances of these species. Measurements were made on both sun and shade saplings of six species: Arbutus m e n z i e s i i (Ericaceae), C h r y s o l e p i s c h r y s o p h y l l a (Fagaceae), L i t h o c a r p u s d e n s i f l o r u s (Fagaceae), Quercus c h r y s o l e p i s (Fagaceae), Quercus w i s l i z e n i i (Fagaceae), and Umbellularia c a l i f o r n i c a (Lauraceae). All species had sclerophyllous leaves with thick epidermal walls, but species differed in leaf specific weight, thickness of mesophyll tissues and in the presence of a hypodermis, crystals, secretory idioblasts, epicuticular deposits, and trichomes. The leaves of Arbutus were 2 – 5 times larger than those of C h r y s o l e p i s, L i t h o c a r p u s and Umbellularia and 4 – 10 times larger than those of both Quercus species. Together with differences in branch architecture, these leaf traits divide the species into groups corresponding to environmental tolerances. Shade-tolerant C h r y s o l e p i s, L i t h o c a r p u s, and Umbellularia had longer leaf lifespans and less palisade tissue, leaf area, and crown mass per volume than the intermediate to intolerant Arbutus and Quercus. Having smaller leaves, Quercus branches had more branch mass per leaf area and per palisade volume than other species, whereas Arbutus had less than other species. These differences in display of photosynthetic tissue should contribute to greater growth for Quercus relative to the other species under high light and limited water, for Arbutus under high light and water availability, and for C h r y s o l e p i s, L i t h o c a r p u s, and Umbellularia under limiting light levels.

Effect of a non‐host plant Phaseolus vulgaris on larval performance and oviposition of the oriental tobacco budworm Helicoverpa assulta (Lepidoptera: Noctuidae)

The oriental tobacco budworm, Helicoverpa assulta, is a specialist herbivore feeding on a few plants of the Solanaceae family including tobacco. Larval performance and adult oviposition of H. assulta were investigated in a non‐host plant, Phaseolus vulgaris (Fabaceae) in comparison with two solanaceous host plants, Nicotiana tabacum and Datura stramonium. Larvae provided with the P. vulgaris leaf died off at day 15, whereas 50% and 40% of larval populations fed on the leaves of N. tabacum and D. stramonium, respectively, survived at day 15. Larval growth upon feeding showed significant difference between the non‐host plant (P. vulgaris) and the host plants (N. tabacum and D. stramonium), but it was not significantly different between the two host plants. In the no‐choice experiment of oviposition, gravid females laid more eggs in N. tabacum and D. stramonium than in P. vulgaris. When the most likely acceptable host plant, N. tabacum, and the non‐host plant, P. vulgaris, were subjected to the choice experiment of oviposition, H. assulta females preferred to lay eggs in N. tabacum, where eggs were continuously laid during the whole experiment period. However, eggs in P. vulgaris were hardly detected throughout the period. This study showed that the non‐host plant, P. vulgaris, had a negative influence on the larval performance and adult oviposition of H. assulta, implying neonate stage is critical for larval survivorship, and ovipositional preference by the female is highly specialized to host plants. Further investigation is required to identify non‐host factors, which could be applied to the development of alternative pest management strategy against H. assulta.     

The cDNA Microarray Profiling of Protein Kinases and Phosphatases: Molecular Portrait of Human Prostate Carcinomas

Hybridization with cDNA arrays was used to obtain expression profiles of 263 protein-tyrosine kinase (PTK), protein-tyrosine phosphatase (PTP), dual-specific phosphatase (DuSP), and other genes for the normal prostate tissue, primary prostate carcinomas (PC) of 84 patients, 7 xenografts, and 5 carcinoma cell lines. Analysis of 96 profiles revealed eight clusters of genes coexpressed in PC (coefficient of correlation r > 0.7). According to the known functions of their genes, the clusters were designated as proliferating-cell (CDC42, TOP2A, FGFR3, MYC, etc.), neoangiogenesis and blood-cell (LCK, VAV1, KDR, VEGF, MMP9, SYK, PTPRS, and FLT4), invasion-1 and invasion-2 (ADAM17, TRPM2, DUSP6, VIM, CAV1, CAV2, JAK1, PTPNS1, FYN, and PDGFB), HER2, and PSA/PSM/HER3. Basing on expression profiles of 66 genes, a molecular classification of PC was generated and allowed discrimination between PC and cell lines or xenografts at 98.9% probability. The results suggested that, along with PSA, PSM (FOLH1), callicreine-2, and -2-macroglobulin, cell signaling genes EGFR, HER2, HER3, TOP2, KRT8, KRT18, VEGF, CD44, VIM, CAV1, and CAV2 may serve as diagnostic and prognostic markers in PC. The HER2, VEGF, and CD44 genes and the MMP and ADAM families were assumed to be promising targets for inhibitors of PC cell proliferation and metastasis.
