An Arbuscular Mycorrhizal Fungus (Glomus mosseae) Induces a Defence-like Response in Rubber Tree (Hevea brasiliensis) Roots

Autor: Mireille Ducher, Isabelle Schwob, Alain Coudret

Publikováno v: Journal of Plant Physiology. 156:284-287

The specific activities of cinnamyl alcohol dehydrogenase (EC 1.1.1.-) and cell wall-bound peroxidases (EC 1.11.1.-) were enhanced in roots of Hevea brasiliensis 2 weeks after inoculation with Glomus mosseae, simultaneously with an increased lignin c

Starch, Storage Protein and Triglyceride Accumulation and Respiration in Developing Embryos in Hevea brasiliensis

Autor: Alain Coudret, Mireille Ducher, Corinne Courty

Publikováno v: Journal of Plant Physiology. 154:686-690

Summary Starch, storage protein and triglyceride contents and respiratory rate were studied in an embryogenic strain of Hevea brasiliensis during development of somatic embryos. For comparison, a non-embryogenic strain was also investigated. The deve

Comparison of starch, ADP-glucose pyrophosphorylase and starch synthase levels in non-embryogenic cells and developing embryos in Hevea brasiliensis

Autor: Corinne Courty, Alain Coudret, Mireille Ducher

Publikováno v: Journal of Plant Physiology. 153:469-474

Summary Sucrose, glucose, fructose and starch levels, and ADP-glucose pyrophosphorylase (EC 2.7.7.27) and starch synthase (EC 2.4.1.21) activities were studied in an embryogenic strain of Hevea brasiliensis during the periods of multiplication of pro

Analyzing the Influence of Qualitative Resistance Selection Pressure on Variation of Aggressiveness in Plasmopara Halstedii

Autor: Jeanne Tourvieille, Mireille Ducher, Denis Tourvieille de Labrouhe, Nachaat Sakr, François Delmotte, Pascal Walser, Felicity Vear

Publikováno v: Journal of Plant Protection Research. 51

Variation of aggressiveness in populations of race 710 of Plasmopara halstedii ((Farl.) Berl. et Toni) (sunflower downy mildew) was measured under different strategies of qualitative resistance selection pressure: mixture, alternation and monoculture

Les β-carboxylations dans les systèmes cellulaires de type C3

Autor: Mireille Ducher, Alain Coudret

Publikováno v: Acta Botanica Gallica. 140:101-112

Summary β-carboxylations (PEPC, PEPCK) appeared wide—spread in plants. This metabolic pathway occured as well in high plants as in algae, fungi, bacteria, and cellular suspensions in multiplication. Relative carbon incorporation induced by this pa

For the first time, a method was used to measure aggressiveness of two Plasmopara halstedii races (100 and 710), the parasite causing sunflower downy mildew. Two sunflower lines showing different levels of quantitative resistance were used to measure

Trees-Structure and Function, Springer Verlag, 1998, 12 (4), pp.236-240. ⟨10.1007/PL00009714⟩

The beneficial effect of arbuscular mycorrhizal (AM) fungi on plant growth is well known, but the physiological processes involved are still discussed. The purpose of this study was to determine if Glomus mosseae affects the growth of Hevea brasilien
