Background and Aims Watermelons, Citrullus species (Cucurbitaceae), are native to Africa and have been cultivated since ancient times. (shabupc.com)
Genomes2
Three out of nine HCT strains investigated have undergone large-scale chromosome alterations, reflecting the remarkable plasticity of Fo genomes. (nature.com)
We here apply genome-structural data to infer relationships in an ancient allopolyploid lineage, the walnut family (Juglandaceae), by using seven chromosome-level genomes, two of them newly assembled. (bvsalud.org)
Sequences3
The genome of Fo is typically divided into a set of eleven 'core' chromosomes, with sequences generally conserved in all Fusarium species, and responsible for housekeeping, and one or several transposon-rich and gene-poor 'accessory' chromosomes 13 . (nature.com)
Wen-Hsiung Ko Abstract: Background: Analysis of phylogenetic relationship of 91 isolates of Phellinus noxius obtained from 46 plant species in Taiwan did not show distinct grouping based on ITS sequences. (gov.tw)
Conclusion: Phylogenetic analysis of ITS sequences among Phellinus species showed that isolates of P. noxius were in the same clade distinctly separated from other Phellinus species. (gov.tw)
Typically2
The fruit flesh of wild watermelons is watery, but typically hard-textured, pale-coloured and bland or bitter. (shabupc.com)
In de novo Illumina assemblies, accessory chromosomes are typically dispersed over many contigs or scaffolds due to their high repeat-content, making it impossible to determine how many accessory chromosomes are present in a strain. (nature.com)
Gene2
Through horizontal chromosome transfer (HCT) to a non-pathogenic strain, we also show that the accessory chromosome containing the SIX gene homologs is indeed a pathogenicity chromosome for cucurbit infection. (nature.com)
In lineages of allopolyploid origin, sets of homoeologous chromosomes may coexist that differ in gene content and syntenic structure. (bvsalud.org)
Plant4
Colchicine is widely used in plant breeding for inducing polyploidy, where the number of chromosomes in plant cells are doubled. (wikipedia.org)

In each hill, plant 4 or 5 seeds, spread 3" apart, and keep only the best seedling for each hill, snipping off the others at soil level. (thedailygarden.us)
127 rare and endangered species listed in 《China Plant Red Data Book》 were found in Yangtse River valley. (jipb.net)
Plants3
In the process, however, watermelon plants lost much of their genetic diversity. (shabupc.com)
Climate change is shifting the growing seasons of plants, affecting species performance and biogeochemical cycles. (bvsalud.org)
The plants in the first rank composed cf 8 endemic species natively grown the valley with only one population for which effective measures should be taken for active preservation. (jipb.net)
Lost1
Conversely, complete loss of virulence was observed in Forc016 strains that lost this chromosome. (nature.com)
Spread1
Sweet dessert watermelons spread across the Mediterranean world during Roman times. (shabupc.com)
Found1
Indeed, the researchers found that cultivated watermelon was domesticated by breeding out the bitterness and increasing sweetness, fruit size and flesh color. (shabupc.com)
Origin1
Conclusions The diverse evidence, combined, indicates that northeastern Africa is the centre of origin of the dessert watermelon, that watermelons were domesticated for water and food there over 4000 years ago, and that sweet dessert watermelons emerged in Mediterranean lands by approximately 2000 years ago. (shabupc.com)
Content1
Because of its great water content, early explorers used watermelons as canteens. (shabupc.com)
Humboldt's 1815 depiction, by contrast, shows a distribution of high-vegetation belts that is consistent with La Condamine's description, while the 1824 depiction drops innovations made in 1815 and returns to simply showing numerous species' names, thus not applying Humboldt's own earlier zonation framework.
