Genotypic variation in response to salinity in a new sexual germplasm of Cenchrus ciliaris L.
(2016)As part of breeding program for new salt- tolerant sexual genotypes of Cenchrus ciliaris L., we evaluated the salt- stress response of two new sexual hybrids, obtained by controlled crosses, at seedling and germination stages. -
Assessment of genetic and epigenetic changes in virus-free garlic (Allium sativum L.) plants obtained by meristem culture followed by in vitro propagation
(2016-01)Garlic (Allium sativum) is a worldwide crop of economic importance susceptible to viral infections that can cause significant yield losses. Meristem tissue culture is the most employed method to sanitize elite cultivars. ... -
Differential characteristics of photochemical acclimation to cold in two contrasting sweet sorghum hybrids
(Wiley; Scandinavian Plant Physiology Society, 2016-08)Sweet sorghum has a photosynthetic system which is highly sensitive to cold stress and hence strongly limits its development in temperate environments; therefore, the identification of key exploitable cold tolerance traits ... -
Response of determinate and indeterminate soybean cultivars to basal and topdressing N fertilization compared to sole inoculation with Bradyrhizobium
(Elsevier, 2016-08)Soybean (Glycine max (L.) Merrill) new cultivars have high N demands to sustain increasing grain yields. One may ask whether these cultivars would need basal and/or topdressing N application as perhaps symbiotic N2 fixation ... -
An Autophagy-Related Kinase Is Essential for the Symbiotic Relationship between Phaseolus vulgaris and Both Rhizobia and Arbuscular Mycorrhizal Fungi
(American Society of Plant Biologists, 2016-09)Eukaryotes contain three types of lipid kinases that belong to the phosphatidylinositol 3-kinase (PI3K) family. In plants and Saccharomyces cerevisiae, only PI3K class III family members have been identified. These enzymes ... -
Factors Affecting Tocopherol Concentrations in Soybean Seeds
(American Chemical Society, 2016-10-31)Soybean seeds contain several health-beneficial compounds, including tocopherols, which are used by the nutraceutical and functional food industries. Soybean tocopherol concentrations are, however, highly variable. Large ... -
Salt tolerance variability among stress‐selected Panicum coloratum cv. Klein plants
(Wiley; British Grassland Society; European Grassland Federation, 2016-11)This work assessed intracultivar variability for salt tolerance within Panicum coloratum cv. Klein, explored some physiological parameters potentially associated with it and evaluated the contribution of cell division and ... -
Silencing of the tomato phosphatidylinositol‐phospholipase C2 (SlPLC2) reduces plant susceptibility to Botrytis cinerea
(Wiley, 2016-12)The tomato [Solanum lycopersicum (Sl)] phosphatidylinositol‐phospholipase C (PI‐PLC) gene family is composed of six members, named SlPLC1 to SlPLC6, differentially regulated on pathogen attack. We have previously shown ... -
Changes in the relationship between temperature during the seed‐filling period and soya bean seed isoflavones under water‐deficit conditions
(Blackwell, 2016-12)Isoflavones have been shown to have health‐promoting activities in humans and are particularly abundant in soya bean. This study was conducted to determine how water deficit during seed fill affects the already known ... -
Potential Uses of Wild Germplasms of Grain Legumes for Crop Improvement
(2017)Challenged by population increase, climatic change, and soil deterioration, crop improvement is always a priority in securing food supplies. Although the production of grain legumes is in general lower than that of cereals, ... -
Day length modulates precocity and productivity through its effect on developmental rate in Origanum vulgare ssp.
(Elsevier, 2017-04)In Origanum spp. knowledge about mechanisms controlling development and growth in response to environmental factors such as temperature and photoperiod, is critical to improve management practices and varietal selection ... -
Germination characteristics of five coexisting neotropical species of Acacia in seasonally dry Chaco forests in Argentina
(Wiley, 2017-04)At a regional scale, habitat heterogeneity can play a very important role in allowing the coexistence of species through their specialization in the use of patches differing in environmental conditions. Here, we explore ... -
In vitro selection and characterization of buffelgrass somaclones with different responses to water stress
(2017-08)Buffelgrass is a forage grass that reproduces mainly by apomixis. In species with this reproduction mode, in vitro selection allows the incorporation of alternatives in a breeding program. The aims were to define a protocol ... -
Water Deficit Modulates the Relationship between Temperature and Unsaturated Fatty Acid Profile in Soybean Seed Oil
(Crop Science Society of America, 2017-08-23)Soybean [Glycine max (L.) Merr.], a major source of vegetable oil worldwide, contains unsaturated fatty acids (UFA) beneficial for human health, leading to the use of soybean oil in nutraceuticals. The objective of this ... -
Nutrient deficiency and hypoxia as constraints to Panicum coloratum growth in alkaline soils
(Wiley; British Grassland Society; European Grassland Federation, 2017-12)Alkaline and saline–alkaline soils impose severe restrictions on plant growth. Panicum coloratum var. coloratum is a perennial C4 forage grass widely used in tropical and subtropical environments. Published information on ... -
