Spinach, Spinacia oleracea

Despite the difficulties in extracting and identifying colorless catabolic products that are extremely labile and detectable only in trace amounts, several of the mysteries of chlorophyll catabolism have been revealed and about 14 non-fluorescent chlorophyll catabolytes (NCCs) from higher plants, mainly in senescent leaves, have been detected and analyzed structurally. Among them, NCCs from rapeseed (Bms-sica napus) from Liquidambar styraciflua, from Cercidiphyllum japonicum, five NCCs from degreened leaves of spinach Spinacia oleracea) and, more recently, two NCCs from tobacco Nicotiana rusticd) and five NCCs from Arabidopsis thaliana have been identified.

In our first experiments (1) we subjected bean, spinach (Spinacia oleracea L.) and tobacco leaves to ozone at 1 ppm for 30 to 60 min. At this high concentration of ozone, the sulfhydryl content of the leaves was diminished 15 to 25% (Table I). There was little difference between the sulfhydryl content of ozone-resistant and ozone-susceptible tobacco either before or after ozonation.

Ogawa et al. (1997) investigated the formation of H202 and the superoxide radical (02 ) in spinach (Spinacia oleracea) hypocotyls with the use of histochemical stains. Nitroblue tetrazolium (NBT) is used to detect 02 radicals. The colored reaction product formazan was only detected in the vascular tissue of developing spinach hypocotyls if CuZn-superoxide dismutase (CuZn-SOD E.C. 1.15.1.1) was inhibited by DDC...

The uptake and biotransformation of benzene from soil and from the atmosphere have been studied in a number of plants, and it was shown that in leaves of spinach (Spinacia oleracea), the label in 14C-benzene was found in muconic, fumaric, succinic, malic, and oxalic acids as well as in specific amino acids, and that an enzyme preparation in the presence of NADH or NADPH produced phenol (Ugrekhelidze et al. 1997).
