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.

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.

Abstract The effects of ethylene on the induction of phenylalanine ammonia-lyase (PAL) by cell wall elicitors of Colletotrichum lindemuthianum was investigated in leaves of susceptible and resistant cultivars of Phaseolus vulgaris (cultivars Pinto and Kievit respectively).

Phenylalanine ammonia-lyase (PAL) catalyzes the rate-limiting step of phenylpropanoid biosynthesis in plants and supplies precursors for a variety of secondary metabolites, such as flavonoids, lignins and stilbenes. The first draft of the full Medicago truncatula genome assembly has been released.

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.

ABSTRACTThere has been scepticism about plants responding to information from their damaged neighbor plants since it was first reported, although a growing body of evidence indicates that interplant communication may play a key role in the resistance of plants. Cotton aphids and corn borer are important insects in cotton and maize, respectively.

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 ...

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.

The induction of PAL in Rhodotorula glutinis and transformation of L-phenylalanine from trans-cinnamic acid were studied. The optimum medium for PAL induction was composed of (g/L) 10.0 yeast extract, 10.0 peptone, 5.0 NaCl, 0.5 KH2 PO4, 0.5 phenylalanine 1.0 (NH4)2SO4 and 5.0 glucose, pH 6.0-6.5. The cultivation temperature was 30.0 degrees C.
