New insight into how thigmomorphogenesis affects Epipremnum aureum plant development
(2018-09)Climbing Epipremnum aureum plants develop larger leaves than unsupported, hanging plants. This effect may be regarded, in part, as a thigmomorphogenic response, but gravimorphogenetic effect may also be involved, since ... -
Characterization of cardoon accessions as feedstock for biodiesel production
(Elsevier, 2018-08-27)Diesel fuels have an essential function in industrial economies. In the last decade, several studies were conducted in order to find alternative sources of vegetables oils suitable to biodiesel conversion. The present ... -
Molecular mapping of vernalization requirement and fertility restoration genes in carrot
(2013-02)Carrot (Daucus carota L.) is a cool-season vegetable normally classified as a biennial species, requiring vernalization to induce flowering. Nevertheless, some cultivars adapted to warmer climates require less vernalization ... -
Expression and mapping of anthocyanin biosynthesis genes in carrot
(2013-07)Anthocyanin gene expression has been extensively studied in leaves, fruits and flowers of numerous plants. Little, however, is known about anthocyanin accumulation in roots of carrots or other species. We quantified ... -
Genetic structure and domestication of carrot (Daucus carota subsp. sativus) (Apiaceae)
(2013-05)• Premise of the study: Analyses of genetic structure and phylogenetic relationships illuminate the origin and domestication of modern crops. Despite being an important worldwide vegetable, the genetic structure and ... -
Diversity, genetic mapping, and signatures of domestication in the carrot (Daucus carota L.) genome, as revealed by Diversity Arrays Technology (DArT) markers
(2014-03)Carrot is one of the most economically important vegetables worldwide, but genetic and genomic resources supporting carrot breeding remain limited. We developed a Diversity Arrays Technology (DArT) platform for wild and ... -
Epigenetic patterns newly established after interspecific hybridization in natural populations of Solanum
(Wiley, 2013-10)Interspecific hybridization is known for triggering genetic and epigenetic changes, such as modifications on DNA methylation patterns and impact on phenotypic plasticity and ecological adaptation. Wild potatoes (Solanum, ... -
Influence of Fusarium spp. isolate and inoculum density on resistance screening tests in onion
(Brazilian Phytopathological Society, 2014)Fusarium basal rot (FBR), which is caused predominantly by Fusarium oxysporum and F. proliferatum, is the main limiting factor of onion crops. Resistant cultivars obtained in other countries do not behave as such in ... -
Short‐term hybridisation activates Tnt1 and Tto1 Copia retrotransposons in wild tuber‐bearing Solanum species
(2015-07)Interspecific hybridisation in tuber‐bearing species of Solanum is a common phenomenon and represents an important source of variability, crucial for adaptation and speciation of potato species. In this regard, the effects ... -
Development and characterization of SSR markers for Trichloris crinita using sequence data from related grass species = Desarrollo y caracterización de marcadores moleculares SSR para Trichloris crinita usando secuencias de gramíneas filogenéticamente cercanas
(Universidad Nacional de Cuyo. Facultad de Ciencias Agrarias, 2018)Trichloris crinita is among the most important native forage grasses in arid regions of America. Despite its importance, molecular resources and sequence data are extremely scarce in this species. In the present study, ... -
Caracterización por contenido de β-carotenos de ocho cultivares de zanahoria (Daucus carota L.) y su relación con el color = Characterization β-carotene content of eight cultivars of carrot (Daucus carota L.) and its relation to the color
(Universidad Nacional de Cuyo. Facultad de Ciencias Agrarias, 2013)El objetivo fue determinar, durante dos años, el contenido de β-caroteno y su relación con el Índice de Color (IC), de ocho cultivares comerciales del tipo 'Flakkee' cultivadas en el INTA La Consulta. El diseño ... -
Effect of colchicine and amiprophos-methyl on the production of in vitro doubled haploid onion plants and correlation assessment between ploidy level and stomatal size = Efecto de la colchicina y del amiprofos-metil en la producción in vitro de plantas dihaploides de cebolla y determinación de la correlación entre el nivel de ploidía y tamaño de los estomas
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2013)Doubled haploid onion (Allium cepa L.) plants allow the production of completely homozygous lines for a later production of hybrids. The haploid plants are normally produced using in vitro gynogenesis. The obtained haploid ... -
Adjustment of a rapid method for quantification of Fusarium spp. spore suspensions in plant pathology = Ajuste de un método rápido para la cuantificación de suspensiones de esporas de Fusarium spp. en fitopatología
(2015-06)The use of a Neubauer chamber is a broadly employed method when cell suspensions need to be quantified. However, this technique may take a long time and needs trained personnel. Spectrophotometry has proved to be a rapid, ... -
Exploiting genetic and physiological variation of the native forage grass Trichloris crinita for revegetation in arid and semi‐arid regions: An integrative review
(2018-06)In arid, semi‐arid and dry subhumid regions, which represent ~ 41% of the Earth's land surface, desertification and soil degradation are very frequent, leading to low soil fertility and productivity. In these regions, ... -
Analytical methods for bioactive sulfur compounds in Allium: An integrated review and future directions
(2017)Plant organosulfur compounds represent one of the main groups of phytochemicals that evidence an ample spectrum of biological activities. There are two major sources of sulfur-containing compounds in plant foods; Allium ... -
Loss of anthocyanins and modification of the anthocyanin profiles ingrape berries of Malbec and Bonarda grown under high temperature conditions
(2017)Malbec and Bonarda are the two most widely cultivated grape varieties in Argentina, and their derivedred wines are recognized worldwide, being their intense color a major quality trait. The temperature dur-ing fruit ripening ... -
Organosulfur and phenolic content of garlic (Allium sativum L.) and onion (Allium cepa L.) and its relationship with antioxidant activity
(2016)Garlic and onion have a role in decreasing risks of chronic diseases due to their antioxidant activity. These biological effects have been attributed in part to organosulfur and flavonoid compounds present in Allium. The ... -
