(Wiley, 2020-06)This is the first report about Na and K fluxes and heritability of Na exclusion in the Elymus genus. Argentine wheatgrass (Elymus scabrifolius ) is an important forage genetic resource for saline environments. A previous ... -
Morphological and molecular characterization of a hybrid zone between Prosopis alba and P. nigra in the Chaco region of northwestern Argentina
(JD Sauerlaender's Verlag, 2020-06-26)The Gran Chaco is the largest dry forest in South America. One of the key taxa of this biome is the genus Prosopis (Fabaceae) which contains several economically important species. One of the characteristics of this genus ... -
Differential response of Trichloris ecotypes from different habitats to drought and salt stress
(Springer, 2020-08-05)Native plant genetic resources have evolved from long processes of natural selection and adaptation to specific environments, and have developed tolerance to various stresses prevailing in their natural habitats via adaptive ... -
Morpho‐physiological traits associated with drought responses in soybean (Glycine max L.)
(2020-08-26)Drought is currently a major constraint to soybean production worldwide and is becoming more widespread due to increased aridity and warmer temperatures in the context of global climate change. In this context, breeding ... -
Contrasting adaptive responses to cope with drought stress and recovery in Cenchrus ciliaris L. and their implications for tissue lignification
(Wiley, 2020-11-12)Cenchrus ciliaris L. is a widely used species for cattle feed in arid and semi-arid regions due to good forage value and known tolerance to drought conditions. Here, we provide insights to adaptive responses of two contrasting ... -
Ammonium stress increases microautophagic activity while impairing macroautophagic flux in Arabidopsis roots
(Wiley, 2020-11-22)Plant responses to NH4 + stress are complex, and multiple mechanisms underlying NH4 + sensitivity and tolerance in plants may be involved. Here, we demonstrate that macro‐ and microautophagic activities are oppositely ... -
La recula, como alternativa productiva en los sistemas hortícolas Pampeanos
(Facultad de Agronomía, Universidad Nacional de La Pampa, 2020-12)La horticultura pampeana, se sustenta en hortalizas de hoja cultivadas en invernaderos, la rúcula ocupa el cuarto puesto en lo que respecta a superficie y producción. En la última década, el cultivo comienza a ser importante ... -
Leaf structure and ultrastructure changes induced by heat stress and drought during seed filling in field-grown soybean and their relationship with grain yield
(Academia Brasileira de Ciências, 2021)Studies focusing on terminal drought combined with heat impacts on plants of agronomic value remain scarce, and even less under field conditions. The objective of this study was to investigate leaf structural and ultrastructural ... -
Prospective genetic gain to improve salinity tolerance in a population of Panicum coloratum var. coloratum with two different selection methods
(CIAT, 2021)Panicum coloratum var. coloratum is a subtropical grass for potentially increasing forage production in lowly productive environments where cattle-raising activities have been relocated. Heritability was estimated for ... -
Cassava common mosaic virus infection causes alterations in chloroplast ultrastructure, function and carbohydrate metabolism of cassava plants
(Wiley, 2021-01)Cassava common mosaic virus (CsCMV) is a potexvirus that causes systemic infections in cassava plants, leading to chlorotic mosaic and producing significant yield losses. To date, the physiological alterations and the ... -
Provenance matters: variability under saline stress in young plants of four populations of a Prosopis (mesquite) species from dry forests of Argentina
(Canadian Science Publishing, 2021-01-04)The planting of native perennial woody species tolerant to variable salt concentrations can facilitate the recovery of degraded dry forests. The objective of this study was to evaluate and compare, under experimentally ... -
Lead uptake and translocation pathways in soybean seedlings: the role of ion competition and transpiration rates
(Springer, 2021-01-06)Glycine max (L.) Merr. (soybean) crop plants have been found to have high lead (Pb) levels in aerial organs; however, knowledge about the processes involved in the incorporation, and subsequent translocation and accumulation ... -
Assessment of lead tolerance on Glycine max (L.) Merr. at early growth stages
(Springer, 2021-01-11)Lead (Pb) contamination of agricultural soils, and subsequently of crops, has been widely reported. Soybean (Glycine max (L.) Merr.) has been indicated as a plant that accumulates Pb, even in soils that do not exceed the ... -
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 ... -
