The centromere represents a single region in most eukaryotic chromosomes. However, several plant and animal lineages assemble holocentromeres along the entire chromosome length. Here, we compare genome organization and evolution as a function of centromere type by assembling chromosome-scale holocentric genomes with repeat-based holocentromeres from three beak-sedge (Rhynchospora pubera, R. breviuscula, and R. tenuis) and their closest monocentric relative, Juncus effusus. We demonstrate that transition ...

Spondias L. comprises at least nine Neotropical species, including the widely cultivated S. monbim and S. tuberosa. Umbu-cajá, a putative hybrid between these two species, is also grown. In this paper, the karyotypes of five Spondias species and Umbu-cajá were analysed for evidence of this hybridization. Chromosome banding with chromomycin A3 and the distribution of 5S and 45S rDNA sites were used to characterize the plants, also genomic in situ hybridization using nuclear DNA from both putative ...

CC4 is a satellite DNA from common bean ( Phaseolus vulgaris L.) that is similar to its intergenic spacer (IGS) rDNA. CC4 was originally hypothesized to be an old, fast evolving satellite family that has invaded common bean rDNA. To test this hypothesis and contribute to the understanding of IGS-like satellite DNA evolution, we have investigated its distribution in the genus Phaseolus and related species. CC4 was cloned and used as probe for Southern blot and FISH experiments. CC4 was observed as an ...

Sugarcane is a crop of economic importance in tropical and subtropical countries, with a high diversity of genetic resources and a long history of genetic manipulation (breeding); however, a reassessment of the genetic variability available to breeders is required in order to further the development of modern varieties. Some methods based on morphological and genealogical data have been used, however, morphological characters are influenced by the environment and genealogical data can result in distorted ...

Drought is a major factor in decreased sugarcane productivity because of the resulting morphophysiological effects that it causes. Gene expression studies that have examined the influence of water stress in sugarcane have yielded divergent results, indicating the absence of a fixed pattern of changes in gene expression. In this work, we investigated the expression profiles of 12 genes in the leaves of a drought-tolerant genotype (RB72910) of sugarcane and compared the results with those of other ...

The palm species Syagrus coronata (Mart.) Becc. shows widespread geographic distribution in the "Caatinga" (seasonally dry tropical forest biome) and Atlantic forest domains (rain forest biome), which suggests that environmental variation in the two domains may have modeled the distribution of S. coronata, generating a distinct phylogeographic scenario. This study assessed the phylogeographic structure of S. coronata in the "Caatinga" and Atlantic forest domains using 181 sequences of the trnH-psbA intergenic ...

The genus Stylosanthes includes nitrogen-fixing and drought-tolerant species of considerable economic importance for perennial pasture, green manure and land recovery. Stylosanthes scabra is adapted to variable soil conditions, being cultivated to improve pastures and soils worldwide. Previous studies have proposed S. scabra as an allotetraploid species (2n = 40) with a putative diploid A genome progenitor S. hamata or S. seabrana (2n = 20) and the B genome progenitor S. viscosa (2n = 20). We aimed to provide ...

This study reports the complete chloroplast sequences of three Spondias species. The genome sequences were obtained for Spondias tuberosa, Spondias bahienses, and Spondias mombin using the Illumina sequencing technology by a combination of de novo methods and a reference-guided assembly using Sapindus mukorossi as reference. The genomes of S. tuberosa, S. bahiensis, and S. mombin had 162,036, 162,218, and 162,302 bp, respectively. The coding regions exhibited 130 genes, including 34–35 tRNAs and ...

<i>Phaseolus vulgaris</i> has two 5S rDNA sites in chromosomes 6 and 10 and from two up to nine 45S rDNA sites depending on the accession. The presence of three 45S rDNA sites, in chromosomes 6, 9 and 10, is considered the ancestral state for the species. For <i>P. lunatus</i>, only one 5S and one 45S rDNA sites in distinct chromosomes were known. In order to investigate the homeologies among these rDNA-bearing chromosomes and the stability of the rDNA sites in <i>P. lunatus</ ...

Mitogenomes in plants are well-known as exhibiting high diversity in genome size architecture and repetitive DNA sequences. In this research study, we report on the complete mitochondrial genomes of S. tuberosa and S. mombin using Illumina paired-end and mate-pair end reads. These genomes were obtained by a combination of methods of de novo assembly and contig extension. The mitogenomes of S. tuberosa and S. mombin showed 779,106 bp and 685,788 bp in length, with a total of 35 genes. Genome comparisons ...

Sugarcane has hermaphrodite flowers, however, selfing and cross pollination may occur, resulting in selfed or hybrid progeny. The aim of this study was to analyze the paternity of progenies from biparental crosses, in order to identify true hybrids or progenies originating from pollen of unknown origin. Seventy-six progenies from four crosses were analyzed using three highly polymorphic microsatellite markers (SSR). Progenies showed moderate genetic similarity and were grouped into four distinct ...

Wild species are important sources of genetic variability and may be exploited by breeding programs. Crosses between teosinte and maize occur freely and teosinte serves as genetic source of agronomic traits for introduction in maize. The objective of this study was to estimate genetic variability among and within maize and teosinte populations (Zea mays mexicana). Two sweet maize populations (BR400 and BR402), two common maize populations (Suwan and Pampa) and one teosinte population were analyzed ...

The maize (Zea mays L. ssp. mays) has several related species, called teosinte, which are distributed in various subspecies of Zea and other genera. Among the different types of corn, sweet corn shows a great potential for human food. This type was originated from mutations, which increased the amount of polysaccharide in the endosperm. In Brazil there are populations of sweet corn, common maize and teosinte, however, little is known about their genetic variability. Hence, the aim of this present ...

Spondias tuberosa occurs in the Caatinga domain (seasonally dry tropical forest biome) of north-eastern Brazil, a large biome with ecogeographic regions that may have modelled the population structure of the species. Here we studied the phylogeographic pattern of S. tuberosa using sequences of the accD-psaI plastid region and six SSR markers in individuals distributed across 20 localities. The results for accD-psaI demonstrated nine haplotypes: some of which were exclusive to Caatinga ecoregions, ...

The genus Spondias (family Anacardiaceae) comprises 19 taxa, ten of which occur in Neotropical regions. Spondias bahiensis has been suggested to be a hybrid, although initial evidence does not support this hypothesis. The aim of this study was to test the hypothesis of the hybrid origin of S. bahiensis using high-throughput sequencing with single nucleotide polymorphism (SNP) analysis, characterization of intragenomic nuclear ribosomal DNA (nrDNA), and nuclear and chloroplast phylogenomic analyses. ...

Allopolyploidy is widely present across plant lineages. Though estimating the correct phylogenetic relationships and origin of allopolyploids may sometimes become a hard task. In the genus Stylosanthes Sw. (Leguminosae), an important legume crop, allopolyploidy is a key speciation force. This makes difficult adequate species recognition and breeding efforts on the genus. Based on comparative analysis of nine high-throughput sequencing (HTS) samples, including three allopolyploids ( S . capitata Vogel ...
