(Submitter supplied) Salinization poses a significant challenge in agriculture, exacerbated by anthropogenic global warming. Biostimulants, derived from living microorganisms or natural extracts, have emerged as valuable tools for conventional and organic agriculture. However, our understanding of the molecular mechanisms underlying the effects of biostimulants is very limited, especially in crops under real cultivation conditions. more...

(Submitter supplied) Lettuce (Lactuca sativa L.) is a highly perishable horticultural crop with a relatively short shelf life due to leaf senescence that limits its commercial value and contributes to food waste. Postharvest senescence varies with influences of both environmental and genetic factors. Preharvest genetic factors can be indicative of postharvest quality. Discovery of additional preharvest markers to assess lettuce shelf life is an important step towards increasing the efficiency of lettuce breeding efforts for improved shelf life. more...

(Submitter supplied) The use of new natural eco-sustainable products is becoming an interesting option in order to reduce the use of chemical fertilizers and increase crop yields. Seaweed extracts are gained major attention as plant biostimulants due to their positive effect on plant-growth as well as on improving plants’ tolerance against abiotic stresses. Among the horticulture crops, lettuce (Lactuca sativa L.) is a major fresh vegetable crop in the Mediterranean area, which often requires the use of natural biostimulants to improve both the quantity and quality of production. more...

(Submitter supplied) Enzymatic browning on the cut edge of lettuce significantly limits its quality and shelf life. To characterize its molecular mechanisms, we performed comparative transcriptome analysis of three Romaine lettuce cultivars, Parris Island Cos (PC) with low browning potential, Tall Guzmaine (TG) with high degree of browning and Clemente (CL), a medium degree of browning cultivar derived from TG x PC. Before cutting, the phenylpropanoid and oxidative stress genes, such as PAL1, MYB1 and PPO were up-regulated in PC as compared to TG, while the expressions of genes involved in auxin, cytokinin hormone signalings and defense, such as ARF, AHP and PTI in PC were higher than TG. more...
