Bark necrosis (BN), described and first studied in Côte d'Ivoire in the 1980s (2), affects most modern rubber plantations (i.e., grafted trees with high-yielding clones, intensive exploitation due to tapping frequency, and use of Ethrel as a yield s

The latex from Hevea brasiliensis is expelled from specialized cells upon bark tapping. The latex yield is mainly limited by the duration of the latex flow, which is controlled by coagulation processes. Bark treatment with ethylene is known to delay

Ethylene, used as a stimulant of latex production in Hevea brasiliensis, significantly activates the regenerating metabolism within the laticiferous cells. In this context, attention was focused on glutamine synthetase (GS; EC 6.3.1.2), a key enzyme

Inter and intraspecific variation was analyzed in two Catharanthus species with regard to isozyme polymorphism and indole alkaloid content in roots and leaves. No significant differences in alkaloid production were observed in three groups of C. rose

The main constraint in rubber plantations worldwide is the cessation of latex production because of two syndromes: (i) tapping panel dryness (TPD), a reversible physiological response to overexploitation; and (ii) bark necrosis (BN), an irreversible

Rotenone and its derivatives are well known for their insecticidal properties. They occur naturally as constituents of the roots, stems, and leaves of many leguminous species of the genera Derris, Lonchocarpus, Tephrosia, and Amorpha (Harborne 1971;

Under the effect of ethylene, there is a close parallel between increased latex production and the alkalinisation of laticiferous cytosol, which is parallel with activation of tonoplast ATPase and vacuole (lutoid) acidification. The alkalinisation of

A Catharanthus roseus cell line was selected that synthesised catharanthine exclusively under elicitation. From the first day of culture, treatment with very low concentrations of a Pythium extract did not alter the growth of the suspension but, with
