Summary The activity of L-phenylalanine ammonia-lyase (PAL) was determined in apple embryos cultured in light or in darkness. The effect of the presence of cycloheximide (CH) or D-phenylalanine (D-phe) in the culture medium was studied. The biosynthesis of PAL was investigated using 14 C-leucine incorporation.

Light-mediated changes in the properties of phenylalanine ammonia-lyase (PAL) in pea buds
Plant Science Letters, 1973Abstract Differences in properties of phenylalanine ammonia-lyase (PAL) extracted from the buds of 7-day-old dark-grown pea seedlings and the buds of 7-day-old dark-grown pea seedlings treated with 6 h white light are demonstrated. Attempts to separate these two forms of PAL with normal techniques employed for protein separation have proved negative.

Induction of phenylalanine ammonia‐lyase (PAL) in germinating lettuce seeds (Lactuca sativa)
Physiologia Plantarum, 1983Dry lettuce seeds (achenes of Lactuca sativa L. cv. Grand Rapids) contain no detectable phenylalanine ammonia‐lyase (PAL, EC 4.3.1.5) activity. Enzyme activity could be detected in these seeds within 4 h of imbibition under white light. The specific activity of PAL increased rapidly during the next 12–16 h of imbibition.

Fusarium wilt disease of watermelon (Citrullus lanatus (Thunb.) Matsum & Nakai), caused by Fusarium oxysporum f. sp. niveum (FON), is one of the limiting factors of worldwide watermelon production. In this study, a Fusarium wilt resistant watermelon JSB, which was derived from a spontaneous mutation of the susceptible Sugar Baby (SB), was used to ...

Summary The periderm formation of wound tissue of potato tuber was inhibited temporarily after exposure to S-carvone. In wound tissue of control tubers a suberized cell layer was visible after 4 days whereas in S-carvone treated tissue this was observed only after 14 days in most of the tubers.

Abstract The mechanism of browning, which is a typical chilling-injury of eggplant fruit ( Solanum melongena L.), was investigated by determining the changes of phenolic substances, phenylalanine ammonia-lyase (PAL) and tyrosine ammonia-lyase (TAL) either during storage at 1°C or after exposing fruit to low temperature for various periods ...

Phenylalanine Ammonia-Lyase (PAL) containing microorganisms were isolated from a wide variety of natural habitats. The best 21 strains to emerge from the primary screen were screened for PAL activities in both directions using l-phenylalanine and t-cinnamate substrates.

Abstract The time-course of phenylalanine ammonia-lyase (PAL) activity and of apparent phytochrome content has been determined under continuous farred irradiation. The kinetics of PAL (EC 4.3.1.5) show four phases: after a lagphase (1) which is detectable only in the early stages of the development, PAL activity increases (2), reaches a maximum (3 ...

Phenylalanine ammonia-lyase and cinnamate 4-hydroxylase are important enzymes in allocating significant amounts of carbon from phenylalanine into the biosynthesis of several important secondary metabolites. Tea is an important crop of commerce known for its beverage and medicinally important flavonoid compounds, mainly catechins.

The estimation of phenylalanine ammonia-lyase (PAL)-activity in intact cells of higher plant tissue
Planta, 1976A procedure is described which permits the estimation of the relative activity of phenylalanine ammonia-lyase (E.C. 4.3.1.5.) in intact plant cells, exemplified by buckwheat hypocotyls. Hypocotyl segments are incubated at pH 5.5 with L-[3-(3)H]phenylalanine.
