Late blight, caused by oomycetes Phytophthora infestans is one of the most challenging fungal diseases to manage in tomato plants (Solanum lycopersicum L.). Toward managing disease, conventional breeding has successfully introgressed genetic loci conferring disease resistance from various wild relatives into commercial varieties. The cataloging disease-associated SNP markers and a deeper understanding disease-resistance mechanisms are needed keep up with demand for varieties resistant...

A comprehensive approach using phenomics and global transcriptomics for dissecting plant response to biostimulants is illustrated with tomato (Solanum lycopersicum cv. Micro-Tom Rio Grande) plants cultivated in the laboratory, greenhouse, open field conditions. Biostimulant treatment based on an Ascophyllum nodosum extract (ANE) was applied as a foliar spray two doses (1 or 2 l ha-1) at three different phenological stages (BBCH51, BBCH61, BBCH65) during flowering phase. Both ANE resulted...
