Organic acids (OAs) play an essential role in several cellular biochemical pathways. Released by plant roots, OAs can help them tolerate phytotoxic forms of aluminum (Al) present in acidic soils. Some studies use high-performance liquid chromatography (HPLC), ion chromatography and, more rarely, gas chromatography-mass spectrometry (GC–MS) to analyze exuded OAs, but they are limited to hours or 1–2 days. The main limitation is that OAs are measured only in CaCl2 and AlCl3 solutions, and not in “...

Environmental stressors increase methane (CH4) emissions from plants. Few studies have investigated the interactive effects of multiple abiotic factors on CH4 emissions from plant vegetative organs and almost none from reproductive organs. We examined the combined effects of temperature, ultraviolet-B radiation, and watering regime on aerobic CH4 emissions from plant reproductive parts. Pea (Pisum sativum L. cv. 237J Sundance) plants were grown under two temperature regimes (22/18 °C and 28/24 °...
We examined physiological and growth promotion traits in water-deprived pineapple explants inoculated with two endophytic diazotrophic bacteria. The following questions were addressed: (i) Is the root inoculation efficient to increase bacteria population associated to pineapple explants? (ii) Are nutrient concentrations improved in pineapple explants in response to endophytic bacteria inoculation? (iii) Can endophytic bacteria improve pineapple explants’ growth and photosynthesis? (iv) Is it pos...
New practices to improve the germination and the initial establishment of seedlings are needed to improve crop development in rainfed areas, where drought events may happen just after sowing. Here, we tested the hypothesis that pre-treatment of common bean seeds with S-nitrosoglutathione (GSNO)—a nitric oxide donor (NO)—or calcium (Ca2+) improves the germination and initial seedling growth under water deficit and both, together, will act synergistically. Firstly, common bean seeds were soaked in...
d-amino acids (d-AAs) can be found in soils, and recent studies indicate that plants exhibit multiple behaviors in response to the type of d-AAs present. d-Ala and d-Ser have the greatest adverse effects on plant growth and development, however the role of d-Ala as a source of nitrogen (N) and d-Ser as an agonist of glutamate receptors (GLRs) in plants have been proposed. Though, there is very little knowledge about the role of d-AAs in regulating plant growth. In this paper we report the effect...
It is known that mitochondrial population of living organisms is heterogeneous. Using the density gradient of Percoll or sucrose, we obtained and characterized two distinct mitochondrial subfractions (named “light” and “heavy” according to their sedimentation) from three plant species (Brassica rapa, Zea mays, and Arabidopsis thaliana). Electron microscopy showed that mitochondria of a light subfraction have a poorly developed cristae structure. The respiratory control of these mitochondria was ...
