Abstract Complete chromosomal-level assemblies of fungal genomes are rare. The intimate ecological symbioses and complex reproduction strategies utilized by fungi make highly contiguous, gapless genome assemblies particularly difficult. Here, we use long-read sequencing on the Oxford Nanopore Technology MinION platform to sequence and assemble the genome of Lepraria neglecta (Ascomycota, Lecanorales). In addition to eight contigs ascribable to chromosomes, six of which are assembled telomere-to-telomere, we discovered the presence of a complete MAT locus with two conserved MAT1-2 genes and a putative MAT1-1 pseudogene. The full genome assembly of a widespread, common species presents an opportunity for new insights into lichen reproduction while the presence of the mating-type locus in the genome of an asexual lichen raises fundamental questions about reproductive biology in fungi generally.
摘要真菌基因组的完整染色体水平组装是罕见的。真菌利用的紧密的生态共生体和复杂的繁殖策略使高度连续、无间隙的基因组组装变得特别困难。在这里,我们在Oxford Nanopore Technology MinION平台上使用长读测序来对Lepraria neglecta(Ascomycota,Lecanorales)的基因组进行测序和组装。除了可归属于染色体的八个重叠群(其中六个是端粒组装到端粒)外,我们还发现了一个完整的MAT基因座,其中包含两个保守的MAT1-2基因和一个假定的MAT1-1假基因。广泛分布的常见物种的全基因组组装为深入了解地衣繁殖提供了机会,而无性地衣基因组中交配型基因座的存在则引发了真菌繁殖生物学的基本问题。

A hypervolume approach to niche specialism, tested for the old-growth indicator status of calicioids 一种对生态位专门化的超大体积方法,测试了钙状体的旧生长指标状态

Certain lichen epiphytes are restricted to old-growth forest stands with long ‘ecological continuity’, explained by i) niche specialism and their dependence on microhabitats associated with old stands including veteran or senescent trees, and/or ii) dispersal limitation with probabilities of colonization being relaxed over extended time periods. ‘Calicioid’ species are among the most important old-growth indicators, yet they reproduce sexually via small spores that appear widely dispersed at ecological scales. This suggests that they should have a high level of niche specialism compared to lichen epiphytes in general, explaining their role as old-growth indicators. However, comparisons of niche specialism are challenging, and this study uses epiphytic, corticolous calicioid species as an appropriate test case. Having measured 20 variables that constrain the lichen epiphyte niche, these were collapsed into a ‘hypervolume’ representing the sampled environmental space available for occupancy by lichens in Scotland as a study system. It was then possible to examine the occupancy of this hypervolume by individual lichens (niche breadth), with the proportion/percent occupied used to estimate a niche specialism score. Consequently, epiphyte calicioid species are confirmed to have a high degree of niche specialism compared to lichen epiphytes in general, and compared to other old-growth indicators, with their niche position directed towards drier climates including locally sheltered microhabitats associated with old-growth forest structure.
某些附生地衣仅限于具有长期“生态连续性”的古老林分,解释如下:i)生态位特殊性及其对与古老林分相关的微生境的依赖,包括老树或衰老树,和/或ii)扩散限制,定殖的可能性在长时间内得到放松。”Calicioid物种是最重要的古老生长指标之一,但它们通过在生态尺度上广泛分布的小孢子进行性繁殖。这表明,与附生地衣相比,它们应该具有高水平的生态位专门性,这解释了它们作为古老生长指标的作用。然而,生态位专门性的比较具有挑战性,本研究使用附生、皮质杯状物种作为适当的测试案例。在测量了20个限制地衣附生生态位的变量后,这些变量被分解成一个“超体积”,代表了苏格兰地衣作为研究系统可占用的采样环境空间。然后,可以检查单个地衣对这种超体积的占用情况(生态位宽度),使用占用的比例/百分比来估计生态位专业性得分。因此,与一般附生地衣相比,以及与其他古老的生长指标相比,附生杯状物种被证实具有高度的生态位特殊性,它们的生态位位置指向更干燥的气候,包括与古老的森林结构相关的局部遮蔽微生境。

Normandina acroglypta, as recently circumbscribed, is shown to comprise two species: N. acroglypta s. str. with subsquamulose marginal areoles, two unidentified terpenoids by thin-layer chromatography, and growing over rock; and N. chlorococca, with convex marginal areoles, zeorin or no substances detected by thin-layer chromatography, and growing over bark. Normandina dictyospora is newly described from the Falkland Islands and is characterized by relatively large, submuriform ascospores, and no substances detected.
最近被划定的Normandina acroglypta包括两种:N. acroglypta s.s r.具有近鳞片状的边缘微孔,薄层色谱法未发现两种萜类,生长在岩石上;绿球菌(N. chlorococca)生长在树皮上,边缘微孔呈凸状,薄层色谱检测不到zeorin或无zeorin物质。Normandina dictyospora是最近在福克兰群岛发现的,其特征是相对较大的亚分形子囊孢子,没有检测到任何物质。

Cladonia luteoalba shows a specific pattern in chemical variability. Its chemotype coincides with that of the associated Cladonia thalli. This has led to the formation of various hypotheses, but its true nature has never been clarified. We collected C. luteoalba in Central Europe and Norway. The chemotypes were detected by TLC and the mycobionts and photobionts were identified by Sanger sequencing of ITS rDNA. Mycobiont cultures were obtained and Illumina metabarcoding of the fungal ITS1 rDNA region was performed targeting minor mycobionts within the thalli. None of the methods supported C. luteoalba as a distinct Cladonia species. In phylogenetic analyses, it was placed in C. straminea and the C. coccifera agg., following the pattern in chemistry. No minor Cladonia were detected by metabarcoding or cultivation. Thus, C. luteoalba remains enigmatic as our data did not support its distinction as a separate Cladonia species.
木犀枝在化学变异方面表现出一种特殊的模式。其化学型与相关的分枝杆菌铊的化学型一致。这导致了各种假说的形成,但其真实性质从未得到澄清。我们在中欧和挪威采集了C.luteoalba。通过薄层色谱法检测其化学型,通过ITS rDNA的Sanger测序鉴定分枝杆菌和光生菌。获得分枝杆菌培养物,并针对铊内的次要分枝杆菌进行真菌ITS1 rDNA区域的Illumina代谢编码。没有一种方法支持C.luteoalba作为一种独特的枝孢属物种。在系统发育分析中,它被放在C.straminea和C.coccifera agg。,遵循化学模式。代谢编码或培养均未检测到小分枝杆菌。因此,C.luteoalba仍然是一个谜,因为我们的数据不支持它作为一个单独的Cladonia物种的区别。

Abstract This study investigated the molecular, chemical and morphological variation in the Usnea pectinata aggregate using 42 specimens, 22 from Tanzania and 20 from São Tomé and Príncipe. A total of 31 sequences (13 ITS, 13 nuLSU and 5 RPB1) were generated. The results are presented in two phylogenies: first a three-markers ‘backbone’ phylogeny for the U. pectinata aggregate, where six distinct, strongly supported subclades indicate considerable genetic variation in the dataset; and second, an ITS phylogeny with 47 terminals along with a mapping of morphological and chemistry data. Several well-supported monophyletic clades were recovered in both phylogenies and these may well represent separate species in the complex referred to here as the U. pectinata aggregate. Three morphotypes characterized by axis pigmentation and four by branch shape were noted. Six chemotypes were observed.

Lichenology in Africa 非洲的地衣学

In the past three years The Lichenologist has published c. 90 papers but only four of these were based on African material. Two of these were physiological papers co-authored by one of us (RB), whereas the other two were taxonomic and described new species from South Africa and Kenya. This contrasts dramatically with the 31 papers based on European material. Given the relative sizes of the continents and the diversity of habitats in Africa – from Mediterranean biomes in the north and far south, through deserts, tropical rainforests and savannah to temperate biomes in the south, and from sea level to alpine regions – this is an exceedingly poor return. Even within Africa, the distribution is uneven with three of the four papers being based on South African material, one on Kenyan, and none on western or northern material. The history of lichenology in Africa dates back at least as far as Linnaeus. Johann König, a pupil of Linnaeus, visited Cape Town on his way to India in 1768 and made several collections, including the type collection of Lichen chrysophtalmos (Linnaeus 1771), which we now know as Teloschistes chrysophthalmos [as chrysophthalmus]. However, the first collector to spend any time collecting lichens in southern Africa was Carl Pehr Thunberg between 1772–1775 who, although based in Cape Town, travelled extensively in the interior (Thunberg 1794). In the following 150 years, a number of local collectors became active, including Miss [Olivia?] Armstrong and Peter MacOwen, while European visitors such as Josef Brunnthaler and Friedrich Wilms made extensive expeditions into the interior. Their collections were, of course, taken back to Europe and deposited in European herbaria (LUND, G, W, ZT, etc) and many were described as new species by Johannes Müller (1885–1888), Edvard Vainio (e.g. Vainio 1901, 1926), Alexander Zahlbruckner (e.g. Zahlbruckner 1926, 1932, 1936) and especially Ernst Stizenberger in his Lichenaea Africana (Stizenberger 1890, 1891). These early collectors were primarily botanists who also collected other groups and more details of their activities can be found on the Biographical Database of Southern African Science (http:// www.s2a3.org.za/bio/Main.php). In the early 20th century Paul Andries van der Byl collected lichens extensively (van der Byl 1933a, b, 1935a, b), and in 1950 Ethel Doidge included lichens in her monumental compendium of southern African fungi (Doidge 1950). Subsequently, between 1956–1991, Ove Almborn issued six fascicles (150 collections) of an exsiccate, Lichenes Africani, and also published several other papers on African lichens (Almborn 1966, 1987, 1988, 1989). However, the first person based in South Africa to concentrate on the lichens of southern Africa was Franklin Brusse of SANBI, Pretoria who, between 1984–1994, published c. 40 papers describing taxonomic novelties from South Africa and Namibia.

这些收集的结果发表在几篇论文中(Jatta 1908、1909;Lindau 1911;Hue 1916;Zahlbruckner 1926、1932;Zahlbluckner和Hauman 1936;Cengia Sambo 1937、1938、1939;Maas Geesteranus 1955;Motyka 1961),后来在Carroll Dodge的《非洲热带地衣的治疗》(1953、1956、1957、1959、1964、1971)中进行了总结。20世纪70年代,Hildur Krog和Dougal Swinscow在东非进行了大量收集,他们的收藏最终出版了《东非大型地衣植物群》(Swinscow和Krog,1988年)。其他地衣学家随后的考察大大增加了对东非地衣生物群的了解(Sérusiaux 1978、1979、1981、1984a、b、1989;Ahti等人1987;Almborn 1989;Elix 2002;Lücking&Kalb 2002;Jørgensen 2003;Kalb 2004、2007、2008;Alstrup&Aptrout 2005;Killmann&Fischer 2005;Sérussiaux&Diederich 2005;Frisch等人2006;Sérosiaux等人2006;Bock等人2007;Yeshitela 2008;Archer等人2009;Frisch&Tibell 2010)。在过去的二十年里,我们中的一个人(PK)一直在肯尼亚收集,并更新了肯尼亚地衣清单,该清单将很快公布。

Two of these were physiological papers co-authored by one of us (RB), whereas the other two were taxonomic and described new species from South Africa and Kenya. This contrasts dramatically with the 31 papers based on European material. Given the relative sizes of the continents and the diversity of habitats in Africa – from Mediterranean biomes in the north and far south, through deserts, tropical rainforests and savannah to temperate biomes in the south, and from sea level to alpine regions – this is an exceedingly poor return. Even within Africa, the distribution is uneven with three of the four papers being based on South African material, one on Kenyan, and none on western or northern material. The history of lichenology in Africa dates back at least as far as Linnaeus. Johann König, a pupil of Linnaeus, visited Cape Town on his way to India in 1768 and made several collections, including the type collection of Lichen chrysophtalmos (Linnaeus 1771), which we now know as Teloschistes chrysophthalmos [as chrysophthalmus]. However, the first collector to spend any time collecting lichens in southern Africa was Carl Pehr Thunberg between 1772–1775 who, although based in Cape Town, travelled extensively in the interior (Thunberg 1794). In the following 150 years, a number of local collectors became active, including Miss [Olivia?] Armstrong and Peter MacOwen, while European visitors such as Josef Brunnthaler and Friedrich Wilms made extensive expeditions into the interior. Their collections were, of course, taken back to Europe and deposited in European herbaria (LUND, G, W, ZT, etc) and many were described as new species by Johannes Müller (1885–1888), Edvard Vainio (e.g. Vainio 1901, 1926), Alexander Zahlbruckner (e.g. Zahlbruckner 1926, 1932, 1936) and especially Ernst Stizenberger in his Lichenaea Africana (Stizenberger 1890, 1891).
