Partial and total defoliation during the filling period affected grain industrial and nutraceutical quality in soybean
(Wiley, 2022-01-08)BACKGROUND: Little is known about soybean grain chemical composition response to defoliation. The objectives of our study were: (i) to quantify the impact of different levels and timing of defoliation during the filling ... -
Phenotypic characterization of a sorghum association panel for salinity stress tolerance : Key input for GWAS analysis
(Sociedad Argentina de Fisiología Vegetal, 2023-09-24)Salinity and alkalinity in soils represent a major problem worldwide due to their adverse effect on agriculture, in terms of productivity and sustainability Moreover, this problem is projected to worsen because of climate ... -
Phenotypic, antioxidant and physiological response of citrus japonica (Kumquat) leaves exposed to Xanthomonas citri subsp. citri
(2024-09-26)Citrus canker, caused by Xanthomonas citri subsp. citri (Xcc), is a bacterial disease that affects all citrus species. However, kumquats (C. japonica Thunb) demonstrate significant resistance. This study aimed to investigate ... -
Phosphatidylinositol 3-kinase function at very early symbiont perception: a local nodulation control under stress conditions?
(Society for Experimental Biology, 2018-04)Root hair curling is an early and essential morphological change required for the success of the symbiotic interaction between legumes and rhizobia. At this stage rhizobia grow as an infection thread within root hairs and ... -
Phylogeny and chromosomal differentiation in Cestreae (Solanaceae)
(Wiley, 2025-09)Cestreae is a monophyletic tribe within the subfamily Cestroideae (Solanaceae), comprising the American genera Cestrum, Sessea, and Vestia. While the monophyly of Cestrum has been confirmed by DNA sequences, the phylogenetic ... -
Physiological and anatomical traits associated with tolerance to long‐term partial submergence stress in the Lotus genus: responses of forage species, a model and an interspecific hybrid
(2018-09)Cattle production based on natural pastures is often subject to flooding periods, which affect plant performance and as a result, forage production. Although most forage legumes are not tolerant to flooding, Lotus spp. are ... -
Physiological causes for decreased productivity under high salinity in Boma, a tetraploid Chloris gayana cultivar
(CSIRO Publishing, 2001)Rhodes grass (Chloris gayana Kunth) is widely cultivated in the semi-arid tropics and favoured for salt tolerance; nevertheless, productivity decreases significantly under saline conditions, especially in tetraploid ... -
Physiological characterization of four model Lotus diploid genotypes: L. japonicus (MG20 and Gifu), L. filicaulis, and L. burttii under salt stress
(Elsevier, 2009-09-25)The genus Lotus comprises a heterogeneous group of annual and perennial species. Lotus japonicus (with MG20 and Gifu ecotypes) has been adopted as one of the model legumes in genetic and genomic studies. Other Lotus species, ... -
Plant Biology: New Insight into How Roots 'Mask Up'
(Cell Press, 2021-03-08)Extra- and trans-cellular barriers are essential for root function under even mild stress. New research shows that establishing both the lignin and suberin barriers in the Arabidopsis endodermis requires phenylpropanoid ... -
Plant Tolerance Mechanisms to Soil Salinity Contribute to the Expansion of Agriculture and Livestock Production in Argentina
(Springer, 2021)This chapter addresses salt tolerance mechanisms in crops and woody species cultivated in Argentina, highlighting the contribution of local research to these topics. Work on forages and woody species represents approximately ... -
Plasticity in sunflower leaf and cell growth under high salinity
(Wiley, 2015-01)A group of sunflower lines that exhibit a range of leaf Na+ concentrations under high salinity was used to explore whether the responses to the osmotic and ionic components of salinity can be distinguished in leaf expansion ... -
Polyamines and flavonoids : key compounds in mycorrhizal colonization of improved and unimproved soybean genotypes
(Springer, 2018-11)Modern breeding programs might have caused a reduction in plant responsiveness to arbuscular mycorrhizal fungi (AMF). Flavonoids and polyamines (PAs) are hypothesized to play a role in this symbiosis. We tested the effects ... -
Polyamines and Legumes: Joint Stories of Stress, Nitrogen Fixation and Environment
(Frontiers Media, 2019-11-04)Polyamines (PAs) are natural aliphatic amines involved in many physiological processes in almost all living organisms, including responses to abiotic stresses and microbial interactions. On other hand, the family Leguminosae ... -
