| maternal sex effects and inbreeding depression under varied environmental conditions in gynodioecious fragaria vesca subsp. bracteata. | gynodioecy (coexistence of females and hermaphrodites) is a sexual system that occurs in numerous flowering plant lineages. thus, understanding the features that affect its maintenance has wide importance. models predict that females must have a seed fitness advantage over hermaphrodites, and this may be achieved via seed quality or quantity. females in a population of fragaria vesca subsp. bracteata, a long-lived gynodioecious perennial, do not demonstrate a seed quantity advantage, so this stu ... | 2013 | 23723257 |
| transcriptomics, targeted metabolomics and gene expression of blackberry leaves and fruits indicate flavonoid metabolic flux from leaf to red fruit. | blackberries (rubus spp.) are among the high added value food products relevant for human health due to the increasing evidence of the beneficial effects of polyphenols, which are very abundant in these fruits. interestingly, these compounds also play a role on plant physiology, being especially relevant their role in plant defense against biotic and abiotic stress. hence, we hypothesize that since blackberry fruits have high amounts of flavonols and anthocyanins, leaves would also have high amo ... | 0 | 28428793 |

| [content of selected metals in forest fruits depending on the harvest site]. | contents of selected metals (pb, cd, cu, zn, fe, mn) were determined in samples of forest fruits: blueberry, raspberry and wild strawberry harvested in lublin region from areas considered as potentially not exposed to pollution (skierbieszów landscape park) and potentially polluted areas (cement factory rejowiec s.a.). analyzed fruits originating from stands more exposed to pollution were characterized by higher lead (except from raspberry) as well as other metals contents than those from krasic ... | 2008 | 18807913 |
| [contents of tannins and oxalic acid in the selected forest fruits depending on the harvest site]. | contents of anti-nutritional components (tannins and oxalic acid) were determined in samples of forest fruits: blueberry, raspberry and wild strawberry harvested in lublin region from areas considered as potentially not exposed to pollution (skierbieszów landscape park) and potentially polluted areas (cement factory rejowiec s.a.). study revealed that blueberry and raspberry fruits collected on potentially polluted area were characterized by higher tannins contents than those harvested on potent ... | 2008 | 18666621 |

| identification and analysis of mitogen-activated protein kinase (mapk) cascades in fragaria vesca. | mitogen-activated protein kinase (mapk) cascades are highly conserved signaling modules in eukaryotes, including yeasts, plants and animals. mapk cascades are responsible for protein phosphorylation during signal transduction events, and typically consist of three protein kinases: mapk, mapk kinase, and mapk kinase kinase. in this current study, we identified a total of 12 fvmapk, 7 fvmapkk, 73 fvmapkkk, and one fvmapkkkk genes in the recently published fragaria vesca genome sequence. this work ... | 2017 | 28805715 |
