Abstract

International audience; The cosmetic and fragrance industry largely exploits citrus essential oils (EOs) because of their aromatic properties. EO compositions are complex and differ between fruit pericarp (PEO) and leaf (LEO). Citrus fruit grow in many countries under very different climates. Seventeen citrus cultivars were selected and their similarities between the two collections were verified by SSR (Single Sequence Repeat) and InDel (Insertion and Deletion) markers to assess the effects of the environment and cultivation practices on the EO yield and composition. LEOs and PEOs were extracted by water distillation and analyzed by GC-MS. PEO yields were generally higher in Corsica than in Bahia, especially in the citron family. PEOs in this family were richer in limonene in Bahia than in Corsica while, conversely, neral, geranial and derivatives were present in a higher proportion in Corsican varieties. A few minor components were site-specific, such as nookaton, a pummelo-specific compound that was not present in grapefruit cultivated in Bahia. If climate change over the last 20 years has not affected the PEO composition in Corsica, the contrasted environmental conditions and cultural practices between Bahia and Corsica could possibly explain the EO variations.

Abstract

The chemical composition of the essential oil (EO), microwave extract (ME) and hydrolate extract (HE) from the same batch of leaves of Fortunella japonica, was investigated by combination of chromatographic (GC, CC) and spectroscopic techniques (GC-MS, C-13 NMR). F. japonica essential oil and extracts are complex mixtures of 28-60 compounds being mainly oxygenated sesquiterpenes. The EO composition was dominated by germacrene D (14.9%), beta-elemol (9.1%), cis-guai-6-en-10 beta-ol (6.3%), beta-eudesmol (5.5%), and delta-elemene (5.2%). Limonene was the unique monoterpene identified at appreciable amount (7.1%). The extract obtained by microwave assisted hydrodistillation contained as main components: beta-elemol (12.4%), germacrene D (9.9%), cis-guai-6-en-10 beta-ol (9.0%), beta-eudesmol (8.2%), germacra-1(10),5-dien-4 alpha-ol (7.1%) and alpha-eudesmol (6.4%). Finally, the highest content of oxygenated sesquiterpenes (near 92%) was found in the hydrolate extract displaying cryptomeridiol (23.3%, but totally absent in the EO and ME), beta-eudesmol (20.6%) and alpha-eudesmol (10.7%). Combined analysis by chromatographic and spectroscopic techniques appeared useful for identification of various sesquiterpenols bearing a tertiary alcohol function.

Abstract

International audience; The mandarin horticultural group is an important component of world citrus production for the fresh fruit market. This group formerly classified as C. reticulata is highly polymorphic and recent molecular studies have suggested that numerous cultivated mandarins were introgressed by C. maxima (the pummelos). C. maxima and C. reticulata are also the ancestors of sweet and sour oranges, grapefruit, and therefore of all the "small citrus" modern varieties (mandarins, tangors, tangelos) derived from sexual hybridization between these horticultural groups. Recently, NGS technologies have greatly modified how plant evolution and genomic structure are analyzed, moving from phylogenetics to phylogenomics. The objective of this work was to develop a workflow for phylogenomic inference from Genotyping By Sequencing (GBS) data and to analyze the interspecific admixture along the nine citrus chromosomes for horticultural groups and recent varieties resulting from the combination of the C. reticulata and C. maxima gene pools. A GBS library was established from 55 citrus varieties, using the ApekI restriction enzyme and selective PCR to improve the read depth. Diagnostic polymorphisms (DPs) of C. reticulata/C. maxima differentiation were identified and used to decipher the phylogenomic structure of the 55 varieties. The GBS approach was powerful and revealed 30,289 SNPs and 8,794 Indels with 12.6% of missing data. 11,133 DPs were selected covering the nine chromosomes with a higher density in genic regions. GBS combined with the detection of DPs was powerful for deciphering the "phylogenomic karyotypes" of cultivars derived from admixture of the two ancestral species after a limited number of interspecific recombinations. All the mandarins, mandarin hybrids, tangelos and tangors analyzed displayed introgression of C. maxima in different parts of the genome. C. reticulata/C. maxima admixture should be a major component of the high phenotypic variability of this germplasm opening up the way for association studies based on phylogenomics.

Abstract

International audience; The composition of an oil sample isolated from leaves of Fortunella japonica (Thunb.) Swingle was investigated by combination of chromatographic and spectroscopic techniques. Among the compounds present at appreciable amounts, a special attention was brought to sesquiterpenes bearing a tertiary alcohol function and particularly to germacra-1(10), 5-dien-4 alpha-ol. Indeed, identification of diastereoisomers alpha and beta of germacra-1(10), 5-dien-4-ol has been the subject of controversy in the literature. We report here for the first time C-13 NMR data of the a isomer. The criteria for differentiation of both diastereoisomers are discussed. In parallel, leaf oils from four other Fortunella species (F. crassifolia, F. hindsii, F. margarita and F. obovata) have been analyzed by GC(RI) and C-13 NMR. The main components of the investigated Fortunella leaf oils were beta-elemol (8.7-30.9%), germacrene D (2.1-16.3%), beta-eudesmol(4.6-13.1%) and Delta 9-10-eremophilen-11-ol (1.4-11.2%). The occurrence of germacra-1(10),5-dien-4 alpha-ol (1.1-7.7%) was observed in the five Fortunella leaf oils.

Abstract

International audience; The volatile compositions of juice and peel of clementine (Citrus reticulata x Citrus sinensis var. Commune), mandarin (Citrus reticulata Blanco var. Willow Leaf) and their hybrids were analyzed by headspace solid-phase extraction (HS-SPME) coupled with gas chromatography and either a flame ionization detector (FID) or a mass spectrometer (MS). The major compounds of the volatile fractions of clementine and mandarin were limonene and limonene/gamma-terpinene, respectively. The volatile compositions of juice and peel of the same fruit showed qualitative and quantitative differences. The data analysis established the existence of three main groups based on volatile compounds that correlated with sample genotypes (clementine and mandarin) and fruit samples (peel and juice).

Abstract

We have isolated and characterised microsatellite loci from citrus, to explore the potential of thes markers for cultivar identification, for genetic diversity evaluation and for genome mapping. Small insert library from an homozygous variety Cleopatra mandarin (Citrus reshni) was enriched for (GA) repeats. 960 clones have been sequenced. Pairs of primers for PCR amplification were designed to the flanking region of 250 microsatellites and until now, 100 have been tested for polymorphism and quality of amplification. Considering , the expected sizes of amplified DNA fragments, interpretable amplification products, mendelian segregation and monolocus position, 40 primers pairs have been used to fingerprint 50 accessions of a wide representation of Aurantioideae sub-family. Amplifications were always succefull for true citrus (Poncirus, Fortunella and Citrus) Severinia buxifolia and Eremocitrus glauca while the other genus have less sucess. Cleopatre and Sunki mandarins, known to be very homozygous with other types of markers (RFLP, isozymes) were characterised by 25% of heterozygous loci. A principal co-ordinate analysis and representation of pairwise distance matrices revealed a genetic diversity structure in accordance with the well known relationship and evolution of citrus genera and species. Otherwise, we have analysed the segregation among an inter-generic backcross progeny and mapped 45 microsatellite loci , in addition with 150 AFLP markers. Utilities of these microsatellites markers in our french genetic research program have been discussed. (Texte intégral)

Abstract

International audience; The volatile compounds from leaves and peels of an interspecific citrus somatic hybrid, Citrus aurantifolia (Christm.) Swing. + Citrus paradisi Macfayden, obtained by fusion of protoplasts from lime, Citrus aurantifolia (cv. Mexican Lime) and grapefruit, Citrus paradisi (cv. Star Ruby), were extracted by pentane: ether (1: 1) from liquid nitrogen ball-milled leaves and flavedo and examined by GC-MS in comparison to those of its parents. The hybrid quantitatively retained the ability of the lime parent to synthesize in its leaves the major monoterpene aldehydes (neral, geranial) the monoterpene alcohols (nerol, geraniol), and their acetates, and also the capacity of the grapefruit parent to produce a sesquiterpene aldehyde (beta-sinensal) in its leaves and nootkatone in its peel. Conversely, synthesis of most sesquiterpene hydrocarbons and long chain aliphatic aldehydes, which are present in the lime parent leaves and peel, was strongly inhibited in the hybrid, as in the grapefruit parent. In comparison to its parents, the hybrid overproduced citronellal in its leaves and alpha-sinensal and beta-sinensal in its peel. Based on these results, the future prospects for a better understanding of the inheritance mechanisms with regards to aroma biosynthesis in citrus leaves and peels are discussed.

Abstract

Genetic relationships among 92 individuals of 8 more economically representative species of Citrus (C. reticulata, C. sinensis, C. aurantium, C. paradisi, C. maxima, C. lemon, C. aurantifolia and C. medica) and 17 other species are estimated by the amplification of 10 loci of SSR named STMS (Sequence Tagged Microsatellites). The potential of STMS for cultivar identification in each species has been evaluated and we have performed a neighbour joining analysis in the basis of a dissimilarity matrix among the different genotypes. Polymorphism of 8 STMS was sufficient to obtain genetic aggregations where three main groups were clearly identified: the orange-mandarin group, the pummelo-grapefruit group and the lime-citron-lemon group. The Citrusspecies relationships were in broad agreementwith those established by previous analyses based on molecular markers and morphological traits, suggesting that SSR data will be useful for exploring intra-generic Citrus genetic taxonomy. The studied microsatellites have not allowed distinguishing varietieswithin some of the species known to have evolved by somatic mutations like sweet oranges and sour oranges. However, polymorphism is detected among lemon varieties.

Abstract

Species of the subfamily Aurantioideae are mainly diploid. The existence of polyploid plants within diploid species have been described. They are mostly triploids resulting from 2n garnetes and letraploids coming from the doubling of nucellar cells. Only two species, Fortunella hindsii and Clausena excavata, are describe as totally tetraploid, but the origin of this tetraploidy is not known. The objective of this workwasto study the mechanisms of Clausena excavata meiosis by molecular marker segregation analysis. Two Sequence-Tagged Microsatellite Sites (STMS) loci and one isoenzymatic locus (PGI) are tested on a population of Clausena excavata obtained by androgenesis. All these markers display a disomic inheritance which is the proof of an allotetraploid origin of Clausena excavata. Thus, Clausena excavata is the first allotetraploid species described in the Aurantioideae subfamily. This approach should be extended to the tetraploid somatic hybrids used as parents for triploid synthesis to predict the genetic structures of the 2n gametes.

Abstract

Somatic hybridization is a means of increasing genetic variability of several crops gene pool. not only by overcoming sexual incompatibility between species, but also by combining nuclear, chloroplastic, and milochondrial genomes in new patterns. It appears particularly adapted for citrus regarding the constraint of ils breeding system and the genetic structure of the gene pool. This poster present the major applications of somatic hybridization in citrus on the basis of Cirad and Inra works. Somatic hybridization is done by electrofusion of proloplasts. The regenerated plantlets are characterised by flow cytometry, isozyme analysis, and CAPS cytoplasmic markers Io assess, respectively, the ploidy level and the nuclear and cytoplasmic origins. Somatic hybridization allows the exploitation of polyembryonic (apomictic) and sterile cultivars for the diversification of the tetraploid gene pool. The tetraploid hybrids, that we have obtained for 20 combinations, will be used for further sexual crosses with diploid to create seedless triploid cultivars. Direct triploid synthesis by somatic hybridization between diploid cultivars and haploid lines is also mastered and several hundred tetraploid and triploid plants are in field evaluation under tropical and Mediterranean conditions. The total addition of the genes of the two parents, irrespective to their heterozygosity, finds important applications for rootstock breeding. An intergeneric hybrid (P. trifoliata + C. deliciosa) is very promising for the constraints of the Mediterranean Basin. Alloplasmic plants have been obtained and pave the way for the study of the interaction between nuclear and cytoplasmic genomes.
