The fruit of tomato (Solanum lycopersicum L.) is a berry: red, fleshy and rich in seeds. Its colour is due to the high content of lycopene whose synthesis is activated by the phytoene synthase 1 (PSY1) enzyme, encoded by Psy1 which is distinct from Psy2. In the present study, we ...

In order to improve the germination of tomato seeds in saline conditions, effect of seed priming by various concentrations of salicylic acid (SA) (0, 50, 100 and 150 mg/L), ascorbic acid (ASA) (0, 50, 100 and 150 mg/L) and hydrogen peroxide (HP) (0, 40, 80 and 120 µM) wa...

Tomato plants were grown to the five-leaf stage under uniform conditions in a growth room with a daily light period of 15 h. Plants were sampled at intervals through 24 h periods and the free ninhydrin-positive compounds determined in roots, bleeding sap, stems and shoots (mainly leaves), ...
Acid phosphatase is present in skim milk, in MFGM, and in membrane material in skim milk (Kitchen, 1985). Acid phosphatase required heat treatment at 88°C for 30 min for complete inactivation (Fox, 2003). The enzyme is relatively heat stable; 70% of the activity remained after heating ...
摘要: Induction of plant defense against pathogen attack is regulated by a complex network of different signals. In the present study interaction between hormonal signals [jasmonic acid (JA) or salicylic acid (SA)] and bioagent [arbuscular mychorrhiza (AM) fungi...
PA is usually present in plant tissues in small amounts, whereas accumulation of DPA and also its conjugates has been observed in many plants, especially in association with stress and at some stages of germination. To a lesser extent, PA and DPA can be conjugated to esters of the β-d-...
[3]. In humans, PUFAs can be produced from essential fatty acids obtained from the diet, but the conversion rate is extremely low, especially in infants. Therefore, an external PUFA supplement in the diet is often necessary. For example, the ω-3 DHA and the ω-6 ARA are present in ...
(1961) on endogenous indoleacetylaspartic acid in tomato plants were reexamined. It was shown that two indole compounds were present in ethanolic extract of tomato stems and leaves. The predominating substance was concluded to be N-malonyltryptophan on account of its UV- and IR-spectra, colour ...
