Preparation and phytotoxicity of sorgoleone analogues [PDF]
Química Nova, 2001 3,5-Dimethoxybenzylic alcohol was converted into the 2-acetoxy-5-methoxy-3-(pent-1-yl)-1,4-benzoquinone (12), in seven steps, with an overall yield of 14.6%. The natural quinone sorgoleone (1) was isolated from Sorghum bicolor and converted into the corresponding quinone (13) having a saturated side chain.

Influence of fine process particles enriched with metals and metalloids on Lactuca sativa L. leaf fatty acid composition following air and/or soil-plant field exposure [PDF]
, 2013 We investigate the effect of both foliar and root uptake of a mixture of metal(loid)s on the fatty acid composition of plant leaves. Our objectives are to determine whether both contamination pathways have a similar effect and whether they interact ...

Molecular Plant Pathology, Volume 24, Issue 1, Page 3-15, January 2023., 2023 Botrytis cinerea mutants lacking both Dicer‐like genes displayed a >99% reduction of transposable element‐derived small RNA (sRNA) production, but were not reduced in virulence, indicating redundancy of sRNAs in fungal virulence. Abstract Plant immune responses are triggered during the interaction with pathogens.
