High impact information on Plant Stems

• A recent meeting at the Juan March Foundation in Madrid, Spain brought together plant biologists to discuss the characteristics of plant stem cells that are unique and those that are shared by stem cells from the animal kingdom [1].
• Furthermore, flow velocity measurements were performed on excised plant stems and visualized by the uptake of the MR contrast agent, gadolinium-diethylenetriamine pentaacetic acid (Gd-DTPA) [2].
• In an earlier publication, we reported that galls of A. rufus were associated with changes in enantiomeric ratios of alpha- and beta-pinene emitted by plant stems, and hypothesized that monoterpene stereochemistry served as a mate location cue for adult males [3].
• Spinasterol, 22, 23-dihydrospinasterol and caffeic acid were isolated from the plant stems and characterized [4].
• Five days after planting, the plants were treated against the root fly by pouring onto soil around the plant stem an emulsion of chlorfenvinphos [2-chloro-1-(2,4-dichlorophenyl) ethenyl diethyl phosphate] in water [5].

Associations of Plant Stems with chemical compounds

• At 1 mM nitrate nitrogenase activity per plant stem nodule was not affected, but it was less than 50% in the root nodules as compared to control [6].
