Jasmonic Acid Effect on L. Growth Is Related to Inhibition of Plasma Membrane Proton Pump and the Uptake and Assimilation of Nitrates.

When plants are exposed to environmental stress, their growth is inhibited. Under such conditions, controlled inhibition of growth is beneficial for plant survival. Jasmonic acid (JA) is a well-known phytohormone that limits plant growth, which has been confirmed in several species.

Water and Nutrient Recovery for Cucumber Hydroponic Cultivation in Simultaneous Biological Treatment of Urine and Grey Water.

Water and nutrient deficiencies in soil are becoming a serious threat to crop production. Therefore, usable water and nutrient recovery from wastewater, such as urine and grey water, should be considered. In this work, we showed the possibility of using grey water and urine after processing in an aerobic reactor with activated sludge in which the nitrification process takes place.

Urine and grey water based liquid fertilizer - Production and the response of plants.

Plant cultivation is a key aspect of future long-distance space missions, and the creation of an efficient food system will not be possible without it. The production of fertilizer in space is based on the recovery of water and nutrients from wastewater, such as urine and grey water. In this study, the fertilizer production process was conducted in an aerobic, activated sludge reactor, where nitrification and the process of carbon removal take place.

Plant Plasma Membrane Proton Pump: One Protein with Multiple Functions.

In plants, the plasma membrane proton pump (PM H-ATPase) regulates numerous transport-dependent processes such as growth, development, basic physiology, and adaptation to environmental conditions. This review explores the multifunctionality of this enzyme in plant cells. The abundance of several PM H-ATPase isogenes and their pivotal role in energizing transport in plants have been connected to the phenomena of pleiotropy.

Role of Plasma Membrane NADPH Oxidase in Response to Salt Stress in Cucumber Seedlings.

Antisense oligonucleotide technology as a research tool in plant biology.

An antisense oligonucleotide (ASO) is a short single-stranded deoxyribonucleotide complementary to the sense strand of a selected nucleic acid. As a result, an ASO can modulate gene expression through several mechanisms. The technology based on ASO has already been applied in studies on gene function in mammalian cells and selective therapeutic strategies for many diseases.

Assay of Plasma Membrane H-ATPase in Plant Tissues under Abiotic Stresses.

Plasma membrane (PM) H-ATPase, which generates the proton gradient across the outer membrane of plant cells, plays a fundamental role in the regulation of many physiological processes fundamental for growth and development of plants. It is involved in the uptake of nutrients from external solutions, their loading into phloem and long-distance transport, stomata aperture and gas exchange, pH homeostasis in cytosol, cell wall loosening, and cell expansion. The crucial role of the enzyme in resistance of plants to abiotic and biotic stress factors has also been well documented.

[Plant P-type ATPases].

P-type ATPases are a superfamily of membrane proteins involved in many physiological processes that are fundamental for all living organisms. Using ATP, they can transport a variety of ions and other substances across all types of cell membranes against a concentration electrochemical gradient. P-type ATPases form a phosphorylated intermediate and are sensitive to vanadate.
