Here, we propose a mechanochemical route to manage the disposal of asbestos fibers material from raw chrysotile and asbestos cement, using it as a nutrient source for agriculture. The mechanochemical process, using citric acid as a reactant, led to the fibers? disruption. The constant mixing, the reactants? friction, and the ion migration enabled the formation of calcium/magnesium citrates. Through soil incubation and enzymatic profile analyses, we showed the beneficial effect of these products as readily available carbon to stimulate endogenous microbiota, releasing Ca2+/Mg2+ to correct acid soil pH. The results evidence the potential of these citrates to promote an acidic buffer to the soil and, after their microbiological decomposition, their equivalent effect to commercial limestone for soil pH correction. |

The aim of this study was to identify and isolate genes that are differentially expressed in four selected cotton (Gossypium hirsutum L.) genotypes contrasting according to their tolerance to water deficit. The genotypes studied were Siokra L-23, Stoneville 506, CS 50 and T-1521. Physiological, morphological and developmental changes that confer drought tolerance in plants must have a molecular genetic basis. To identify and isolate the genes, the mRNA Differential Display (DD) technique was used. Messenger RNAs differentially expressed during water deficit were identified, isolated, cloned and sequenced. The cloned transcript A12B15-5, a NADP(H) oxidase homologue, was up regulated only during the water deficit stress and only in Siokra L-23, a drought tolerant genotype. Ribonuclease protection assay confirmed that transcription. |
