Negative short-term salt effects on the soybean–Bradyrhizobium japonicum interaction and partial reversion by calcium addition by Muñoz, Nacira Belen, Rodriguez, Marianela, Robert, German, Lascano, Hernan Ramiro

“…The short-term (2 h) effects of salt stress (50 and 150 mM NaCl) on early events of soybean– Bradyrhizobium japonicum (rhizobia) interaction were analysed, determining the following parameters in root hair with or without calcium addition: deformation, apoplastic superoxide radical production (O2⚫–), root hair death and sodium/potassium ion content. We also analysed whether this short-term salt stress influenced later formation of crown and noncrown nodules, determining the number and weight of nodules. …”

Antifungal Hydroxypropyl Methylcellulose (HPMC)-Lipid Composite Edible Coatings and Modified Atmosphere Packaging (MAP) to Reduce Postharvest Decay and Improve Storability of ‘Moll... by Di Millo, Bruno, Martínez-Blay, Victoria, Pérez-Gago, María B., Argente-Sanchis, Maricruz, Grimal, Amparo, Baraldi, Elena, Palou, Lluís

“…In this work, we evaluated the effect of novel hydroxypropyl methylcellulose (HPMC) edible coatings (ECs) formulated with three different lipids (beeswax (BW), carnauba wax, and glycerol monostearate), as hydrophobic components, and two different GRAS salts (potassium bicarbonate (PBC) and sodium benzoate (SB)), as antifungal ingredients, to control weight loss and natural fungal decay of ‘Mollar de Elche’ pomegranates during storage at 20 °C. …”

Uncovering salt tolerance mechanisms in pepper plants: a physiological and transcriptomic approach by López-Serrano, Lidia, Calatayud, Ángeles, López-Galarza, Salvador, Serrano, Ramón, Bueso, Eduardo

“…Results: The genetic changes found between the accessions under both control and stress conditions could explain the physiological behaviour in A25 by the decrease of osmotic potential that could be due mainly to an increase in potassium and proline accumulation, improved growth (e.g. expansins), more efficient starch accumulation (e.g. …”

Spontaneous Plants Improve the Inter-Row Soil Fertility in a Citrus Orchard but Nitrogen Lacks to Boost Organic Carbon by Visconti, Fernando, Peiró, Enrique, Baixauli, Carlos, De-Paz, José M.

“…The spontaneous plants also enhanced the biological fertility, but in this case, beneficial conditions were reflected by improvements in the chemical fertility, particularly the exchangeable potassium, and in the physical fertility by increasing the surface hydraulic conductivity and decreasing the bulk density. …”

How antinutrients found in legumes and legume-based products affect the bioavailability of nutrients by Johansson, Anna

“…Lectins, tannins, oxalate and protease inhibitors are a few examples that can create problems in the absorption of proteins, iron, potassium, calcium and other nutrients. The level of both nutrients and antinutrients varies between cultivars and within the spices, the stage of harvest and other factors that need further investigation. …”

Nutritional diagnosis of banana (Musa AAA Simmonds subgroup Cavendish) with root sap analysis by Palacio, Manfred Ricardo, Salinas, Daniel Gerardo Cayón, Magnitskiy, Stanislav, García Dávila, Mario Augusto, Castillo Mira, John Jairo

“…The contents of macro (N, P, K, Ca and Mg) and micronutrients (B, Zn, Mn, Fe and Cu) were analyzed in the root sap, leaves and soil at the base of the plant. Potassium was the macronutrient found in the highest quantity in the root sap of the fertilized and unfertilized plants, while the predominant micronutrients were Mn in the fertilized plants and Fe in the unfertilized ones. …”
