Lipidomic Profiling of Argania spinosa L. (Skeels) Following Drought Stress.

Argan tree is frequently constrained by environmental stresses, especially drought. Lipids play crucial roles in stress adaptation, but lipidomic profiles in Argania spinosa under drought stress is largely unknown. The aim of this study was to identify lipid components potentially responsive to drought stress from leaves in the four argan ecotypes.

Evaluation of microalgae polysaccharides as biostimulants of tomato plant defense using metabolomics and biochemical approaches.

Microalgal polysaccharides (PSs) may be an effective elicitor agent that can efficiently protect plants against biotic stresses. In this study, wee investigates, the effect of PS obtained from microalgae and cyanobacteria (D. salina MS002, P.

Using two retrotransposon-based marker systems (SRAP and REMAP) for genetic diversity analysis of Moroccan Argan tree.

The Argania is an endemic genetic resource in Morocco holding an important ecological and socio-economical benefit. However, overgrazing and overharvesting lead to a serious downturn in the number of trees. To characterize genetic diversity within and among 24 populations, represented by 240 argan trees, four combinations of SRAP primers and eight combinations of REMAP primers were used.

Microalgae polysaccharides bio-stimulating effect on tomato plants: Growth and metabolic distribution.

Microalgae polysaccharides represent a potentially bioressource for the enhancement and the protection of agricultural crops. We investigate the possibility to use microalgae polysaccharides as a plant biostimulant. The crude polysaccharides extract (PS) from three microalgae strains were applied to plants by irrigation and compared basing on their effects on shoot and root length, nodes number and shoot and root dry weight.

Effect of Microalgae Polysaccharides on Biochemical and Metabolomics Pathways Related to Plant Defense in Solanum lycopersicum.

Microalgae are photosynthetic microorganisms that produce several bioactive molecules that have received considerable attention in scientific and industrial communities. Today, many plant biostimulants including seaweed extracts and polysaccharides are used in agriculture. However, microalgae have not been largely exploited in this field as a potential source of plant bio stimulants.
