TL;DR: Seaweed polysaccharides and their derived oligosaccharides induced the accumulation of proteins and compounds with antimicrobial activities that determine, at least in part, the enhanced protection against pathogens in plants.

TL;DR: Molecular mechanisms that potentially interconnect activation of plant growth and defense responses are discussed and seaweed oligosaccharides induce a dual beneficial effect in plants and trees, enhancing growth, and defense against pathogens, which is determined by the accumulation of compounds with antimicrobial activities.

TL;DR: Protection against tobacco mosaic virus, Botrytis cinerea Whetzel and Pectobacterium carotovorum Waldee and suppression of infections in tobacco plants with increasing concentrations of oligo-carrageenans, increasing number of treatments and increasing time after treatment enhanced protection against TMV indicating a long-term protection that mimics vaccination.

TL;DR: Copper stress induces calcium release and organellar ROS accumulation that determine the differential activation of antioxidant and defense enzymes.

TL;DR: Algal oligosaccharides differentially stimulate growth and defense against TMV in tobacco plants and that these processes involve the activation of the enzymes AP and PAL, respectively.
