By means of histochemical stains, a change of the composition and internal organization of these structures during their maturation was observed. The formation of sclerotia begins with a clustering of hyphae that gives rise to a structure with pseudoparenchyma in the central part; these immature sclerotia develop to form, at maturity, a pseudoparenchymatic outer cortex of 6 or 7 layers of hyphae around an inner medulla. The hyphae of mature sclerotia have a large number of protein bodies in contrast to scarce lipid accumulations. The formation of sclerotia is influenced by the characteristics of the culture medium and the temperature. The greatest number of sclerotia was obtained by reducing the concentration of the diammonium phosphate to 0.94 mM in the MMN medium, and maintaining the cultures at 8 °C for 2 weeks. Finally it was shown that the sclerotia of this species can be used directly as inoculum, both to generate mycelium in the culture media and to initiate mycorrhizae in birch plants in vitro.","PeriodicalId":55520,"journal":{"name":"Anales Del Jardin Botanico De Madrid","volume":"203 1","pages":"054"},"PeriodicalIF":0.5,"publicationDate":"2017-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76249188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The fruit type in Jodina is controversial since it has been described at different stages of development. The main objective of this work was to analyze the morphology of the fruit of J. rhombifolia during its maturation to attain a consensus about its type. Also characteristics of seed development and anatomy were analyzed in detail. Material was processed according to conventional techniques for LM and SEM studies. The fruit of J. rhombifolia is a pseudodrupe since the ovary is half-inferior; the fleshy layer of the pericarp is constituted by an increase of the nectary disk whereas the stony layer is represented by the mesocarp. Participation of the nectary disk as part of the fruit wall has not been mentioned previously. The seed is “naked” —the integument disintegrates during development— and the resulting structure is a pyrene. The interpretations made by other authors on the fruit of Jodina are also discussed.","PeriodicalId":55520,"journal":{"name":"Anales Del Jardin Botanico De Madrid","volume":"10 1","pages":"051"},"PeriodicalIF":0.5,"publicationDate":"2017-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79711976","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Schedonorus is a group of broad-leaved fescues, which can be divided into two clades: European and Maghrebian. We employed fluorescent in situ hybridization —FISH— with probes specific for 5S and 35S ribosomal DNA and genome size estimation using flow cytometry to shed light on the determination of possible parental genomes of polyploid species of the Maghrebian clade. Our results indicate that octoploid F. arundinacea subsp. atlantigena probably originated from crossing of the tetraploids F. arundinacea subsp. fenas —2n = 4x = 28— and F. mairei —2n = 4x = 28— followed by whole genome duplication. However, a large reconstruction of karyotype and genome downsizing has been revealed. Similarly, hexaploid F. arundinacea subsp. corsica presumably resulted from the interspecific hybridization of the diploid F. pratensis and tetraploid F. arundinacea subsp. fenas . Several scenarios on the origin of decaploid F. arundinacea var. letourneuxiana are discussed. This study contributed to our knowledge on the phylogeny of broad-leaved fescues and provided new information on the karyotypes —chromosome numbers, ploidy levels and numbers and positions of rDNA loci— using FISH and genome size estimations using flow cytometry in selected taxa of this important grass genus.","PeriodicalId":55520,"journal":{"name":"Anales Del Jardin Botanico De Madrid","volume":"50 1","pages":"052"},"PeriodicalIF":0.5,"publicationDate":"2017-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86735252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Algeria, in 2010 its communities covered 10% of the steppe territory, but its populations have been subjected to overgrazing. A karyological study based on 22 populations together with a cytogenetic characterisation of this species has been performed for the first time in Algerian materials, through genome size and chromosome number determination. Fluorescence in situ hybridisation (FISH) was also used to assess the rDNA loci number and distribution in the two ploidy levels detected. The studied accessions are diploid ( 2n = 2x = 18 chromosomes, 6 populations) or tetraploid ( 2n = 4x = 36 chromosomes, 15 populations). One population, occupying a more or less central geographic position among the studied area, presented both cytotypes. Genome size reflects well the two ploidy levels, with no evidence of downsizing with polyploidy. The karyotypes are rather symmetric (2A Stebbins’ class). FISH analyses detected four signals (2 loci) in diploid and eight signals (4 loci) in tetraploid cytotypes for both ribosomal DNA genes, which present an L-type (linked) organisation, i.e. with loci from both rDNA genes colocalised. The presence of two ploidy levels suggest a genomic dynamism and even a possible differentiation underlying the morphological uniformity and despite the dramatic decrease experienced by this plant in Algeria in terms of surface coverage.","PeriodicalId":55520,"journal":{"name":"Anales Del Jardin Botanico De Madrid","volume":"50 1","pages":"043"},"PeriodicalIF":0.5,"publicationDate":"2016-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78463181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
