We examined whether the reduced mycorrhization of abscisic acid (ABA)-deficient tomato mutants correlates with their incapacity in ABA biosynthesis and whether this effect is dependent on ethylene production. The mycorrhization of notabilis and sitiens mutants, which have different ABA deficiencies and an excess of ethylene production, was analyzed. Comparative analysis of the ABA-deficient tom...

Translocation of (14)C-photosynthates to mycorrhizal (+ +), half mycorrhizal (0+), and nonmycorrhizal (00) split-root systems was compared to P accumulation in leaves of the host plant. Carrizo citrange seedlings (Poncirus trifoliata [L.] Raf. x Citrus sinensis [L.] Osbeck) were inoculated with the vesicular-arbuscular mycorrhizal fungus Glomus intraradices Schenck and Smith. Plants were expose...

study the effects of inoculation with two arbuscular mycorrhizal (am) fungi, gm (glomus mosseae t.h. nicolson & gerd.)gerd & trappe) and gi (glomus intraradices  n.c. schenck & g.s. sm.) on the  herb yield, essential oil (eo) content and nutrient acquisition of basil (ocimum basilicum l.) under drought stress conditions,the experiment conducted with 9 treatments and 4 replications. drought stre...

Regulation by arbuscular mycorrhizal symbiosis of three tomato plasma membrane H+-ATPase genes (LHA1, LHA2 and LHA4) has been analysed in wild-type and mycorrhiza-defective tomato plants. Expression of these genes was differentially regulated in leaves and roots of both tomato phenotypes after inoculation with Glomus mosseae.
