In this research phylogenetic relationships of the two genera Fragaria and Duchesnea, including four species ( Fragaria viridis, F. vesca, Duchesnea indica and D. chrysantha) and 2 of their closely related species (Potentilla reptans and P. micrantha) plus 2 Fillipendulla species ( representing outgroups) were carried out using morphological traits. Primarily, morphological evidences of 30 taxa...
A method to sequence multiple chloroplast genomes using ultra high throughput sequencing technologies was recently described. Complete chloroplast genome sequences can resolve phylogenetic relationships at low taxonomic levels and identify informative point mutations and indels. The objective of this research was to sequence multiple Fragaria chloroplast genomes using the Illumina Genome Analyz...
Spintherophyta semiaurata (Klug) is reported for the first time damaging flowers of strawberry (Fragaria x ananassa) in the municipality of São José dos Pinhais, State of Parana, Brazil.
The genetic diversity of commercial cultivars of strawberry Fragaria x ananassa from various parentages, as expressed by their resistance to the northem lesion nematode Pratylenchus penetrans, was evaluated in nematode-infested field plots for two growing seasons. Data taken for each plant in each season included soil nematode Pi and Pf, end-of-season nematode numbers in each entire root system...
Florivores are antagonists that damage flowers, and have direct negative effects on flowering and pollination of the attacked plants. While florivory has mainly been studied for its consequences on seed production or siring success, little is known about its impact on mating systems. Damage to flowers can alter pollinator attraction to the plant and may therefore modify patterns of pollen trans...
BACKGROUND AND AIMS The aims of this investigation were to highlight the qualitative and quantitative diversity apparent between nine diploid Fragaria species and produce interspecific populations segregating for a large number of morphological characters suitable for quantitative trait loci analysis. METHODS A qualitative comparison of eight described diploid Fragaria species was performed a...
organic compounds including seaweed extract were applied in organic production system and sustainable agriculture. one of these compounds is humic acid that was used widely in research and commercial programs. humic acid is an organic acid obtained from humus and other natural resources with hormonal effects and improving nutrient absorption, increasing root and shoot biomass. in order to inves...
Flowering time control is important for fruit production in Fragaria × ananassa. The flowering inhibition pathway has been extensively elucidated in the woodland strawberry, Fragaria vesca, whereas the factors involved in its promotion remain unclear. In this study, we investigated the environmental responses of F. × ananassa FT and TFL1-like genes, which are considered key floral promoters and...
UNLABELLED PREMISE OF THE STUDY Hybrid zones provide "natural laboratories" for understanding the processes of selection, reinforcement, and speciation. We sought to gain insight into the degree of introgression and the extent of ecological-phenotypic intermediacy in the natural hybrid strawberry, Fragaria × ananassa subsp. cuneifolia. • METHODS We used whole-plastome sequencing to identif...
The aim of the study was to investigate changes in the localization of arabinogalactan proteins (AGPs) during ovule development in Fragaria x ananassa Duch. cv. ‘Mount Everest’. For the first time, the localization of AGPs was studied in a hybrid Fragaria x ananassa, which is a facultative apomict. The AGP epitopes were revealed with the use of JIM13 mAb after immune cyto chemical reaction and ...
