Abstract Background In viticulture, iron (Fe) chlorosis is a common abiotic stress that impairs plant development and leads to yield quality losses. Under low availability of the metal, applied N form (nitrate ammonium) can play role in promoting or mitigating Fe deficiency stresses. However, processes involved are not clear grapevine. Therefore, aim this study was investigate response two grapevine rootstocks interaction between forms uptake. This process evaluated hydroponic experiment...
Nitrogen (N) is the nutrient most applied in agriculture as fertilizer (as nitrate, Nit; ammonium, A; and/or urea, U, forms) and its availability strongly constrains crop growth yield. To investigate early response (24 hours) of N-deficient tomato plants to these three N forms, a physiological molecular study was performed. In comparison plants, significant changes transcriptional, metabolomic ionomic profiles were observed. As probable consequence mobility wide metabolic modulation occurred...
In plants the communication between organs is mainly carried out via xylem and phloem. The concentration molecular species of some phytohormones, assimilates inorganic ions that are translocated in vessel play a key role systemic nutritional signaling plants. this work composition sap maize was investigated at metabolic ionomic level depending on N form available nutrient solution. Plants were grown up to 7 days hydroponic system under N-free solution or containing nitrate, urea, ammonium...
Introduction Nitrogen (N) and iron (Fe) are involved in several biochemical processes living organisms, their limited bioavailability is a strong constraint for plant growth yield. This work investigated the interplay between Fe N nutritional pathways tomato plants kept under deficiency then resupplied with (as nitrate, ammonium, or urea) through physiological, metabolomics gene expression study. Results After 24 hours of resupply, concentration Fe-deficient roots was dependent on applied...
Iron (Fe) deficiency is one of the important nutritional disorders for grapevine growing in alkaline and calcareous soils. Although Fe an abundant element soil, several factors limiting its availability, particularly high levels calcium carbonate or bicarbonate leading to a remarkable reduction growth productivity. The use chlorosis-tolerant rootstocks seems be cost-effective efficient way maintain balance. Morphological physiological changes occur plants cope with low including enhancement...
