Due to DNA heterozygosity and repeat content, assembly of non-model plant genomes is challenging. Herein, we report a high-quality genome reference one the oldest known domesticated species, fig (Ficus carica L.), using Pacific Biosciences single-molecule, real-time sequencing. The ~333 Mbp in size, which 80% has been anchored 13 chromosomes. Genome-wide analysis N6 -methyladenine N4 -methylcytosine revealed high methylation levels both genes transposable elements, prevalence methylated over...
Genome divergence by mobile elements activity and recombination is a continuous process that plays key role in the evolution of species. Nevertheless, knowledge on retrotransposon-related variability among species belonging to same genus still limited. Considering importance Helianthus, model system for studying ecological genetics speciation adaptation, we performed comparative analysis repetitive genome fraction across ten one subspecies sunflower, focusing long terminal repeat...
The light spectra influence growth, development and quality of plants seedlings, that is one the main aspects engaging interests private public researchers nursery industries. propagation hazelnut (Corylus avellana L.), which in past has been held low consideration because widespread use rooted suckers directly collected field, today taking on increasing interest due to strong expansion cultivation. In order improve seedlings greenhouse acclimatization, LEDs (Light Emitting Diodes) during ex...
Abstract This paper reports a procedure for isolating triploid and tetraploid olive plants, which have not been produced before either artificially or in nature. These polyploids were isolated from two mixoploid somatic mutants obtained earlier by treating Trantoio' ‘Leccino’ plantlets with gamma radiation. The exhibit increased thickness of leaf, stem root tissues, short internodes, modified leaf lamina shape strong resistance to Spilocaea oleagina (Cast.) Hugh. In addition, they produce...
In Olea europaea L. subsp. , tetraploid genotypes do not exist in nature. Herein, we report the first example of selection olive plants, obtained by combining physical mutagenesis and biotechnology techniques. Stable (4 n ) diploid (2 were isolated vitro through shoot-tip fragmentation two mixoploid mutants derived from gamma irradiation self-incompatible Leccino self-compatible Frantoio cultivars. this study, stable FRM5-4 FRM5-2 LM3-4 LM3-2 characterized field for vegetative reproductive...
Owing to close associations of different chromosomes at their heterochromatic regions, nuclear repatternings consisting changes in the number and size chromocenters may occur with tissue differentiation plant species. By studying these structure a Magnoliopsida chromocentric nuclei, we found: (i) that chromocenter association is affected by degree partitioning genome, since extent phenomenon correlates positively complement, level ploidy, meristematic whereas correlation mean DNA content per...
Gene sequence variation in cultivated olive (Olea europaea L. subsp. var. europaea), the most important oil tree crop of Mediterranean basin, has been poorly evaluated up to now. A deep analysis fragments four genes, OeACP1, OeACP2, OeLUS and OeSUT1, 90 cultivars, revealed a wide range polymorphisms along all recognized allele forms unexpected frequencies genotype combinations. High linkage values among were recorded within each gene fragment. The great variability corresponded low number...
Genomic in situ hybridization was used to study Triticum x Dasypyrum wide hybrids and derived lines. A cytogenetic investigation carried out progenies of (i) amphiploids from T. turgidum var. durum (T. durum; 2n = 14; genomes AABB) D. villosum (2n genome VV), (ii) three-parental villosum) aestivum 42, A'A'B'B'D'D'), (iii) aneuploid lines carrying chromosomes or chromatin. The showed a stable chromosomal constitution, made up 14 V chromosomes, the wheat B genome. High karyological instability...
DNA clones containing highly repetitive sequences were selected from partial libraries of Lathyrus sativus and L. sylvestris. Two satellite sequence families isolated the genome former species. A first family was made up repeats that varied in length 54-56 bp, shared 51.7-94.8% nucleotide similarity. The second 52-62 bp length, a 58.5-78.5% All repeat units contained clone sylvestris 41 showed an almost perfect structural conservation (95.1-100% similarity). evolution studied by dot-blot...
Geranium macrorrhizum L. is a herbaceous species native to southern Europe and was introduced in central North America. It also widely distributed Italy. In this study, molecular cytogenetic analyses were carried out on 22 wild plants, collected Italy, compared with five cultivated the main purpose identify those living near Marmore waterfalls recently described as new lucarinii . Four barcoding markers ( rbcL , matK trnH-psbA intergenic spacer internal transcribed region) sequenced their...
Cytogenetic and DNA molecular analyses have been carried out in 3 wheat introgression lines (ILs; CS×V58, CS×V59, CS×V60) derived from <i>Triticum aestivum</i> cv. ‘Chinese Spring’ (CS) × <i>Dasypyrum villosum</i><i>(Dv)</i> intergeneric hybridization. All lines, which showed several phenotypic differences compared to CS, had the same chromosome number (2n = 42) structure as neither chromosomes nor chromatin <i>Dv</i> were apparently added...
Tandemly repeated DNA sequences about 60 bp in length, which may be isolated by digestion with FokI restriction endonuclease, were studied means of molecular and cytological hybridizations Vicia faba other species. The results obtained can summarized as follows: (i) repeats are almost species specific to V. faba, since they hybridize a minimum extent the genomic only two out five related species; (ii) these tandemly elements display variability structure even within one same array, where...
The current view of plant genome evolution proposes that size has mainly been determined by polyploidisation and amplification/loss transposons, with a minor role played other repeated sequences, such as tandem repeats. In cultivated olive (Olea europaea subsp. var. europaea), available data suggest singular model evolution, in which massive expansion tandem-repeated sequences accompanied changes nuclear architecture. This peculiar scenario highlights the importance focusing on Olea genus to...
