An efficient regeneration system was developed for Kigelia pinnata L., a multipurpose tree belonging to the family Bignoniaceae. The nodal segments were cultured in vitro, and the optimum concentrations of plant growth regulators for callus induction were determined. The friable organogenic calli were derived from the basal cut end of the nodal segments. The highest yield of morphogenic callus ...

AIMS The study aimed to determine whether inoculation with native arbuscular mycorrhizal (AM) fungi could improve survival and growth of seedlings in degraded soils of Morocco. METHODS AND RESULTS Soil samples were collected from the rhizosphere of Cupressus atlantica trees in the N'Fis valley (Haut Atlas, Morocco). AM spores were extracted from the soil, identified and this mixture of native...

The mycorrhizal symbiosis between soil fungi and plant roots is a ubiquitous mutualism that plays key roles in plant nutrition, soil health, and carbon cycling. The symbiosis evolved repeatedly and independently as multiple morphotypes [e.g., arbuscular mycorrhizae (AM), ectomycorrhizal (ECM)] in multiple fungal clades (e.g., phyla Glomeromycota, Ascomycota, Basidiomycota). The accessibility an...

Cell walls are deeply involved in the molecular talk between partners during plant and microbe interactions, and their role in mycorrhizae, i.e., the widespread symbiotic associations established between plant roots and soil fungi, has been investigated extensively. All mycorrhizal interactions achieve full symbiotic functionality through the development of an extensive contact surface between ...

Both mycorrhizae and herbivore damage cause rapid changes in source-sink dynamics within a plant. Mycorrhizae create long-term sinks for carbon within the roots while damage by leaf-chewing herbivores causes temporary whole-plant shifts in carbon and nitrogen allocation. Thus, induced responses to herbivory might depend on the presence or absence of mycorrhizae. We examined the effects of mycor...

Accepted : June, 2009 Mango is one of the most popular fruit crops grown in tropical and subtropical countries. It is considered as ‘National fruit of India’ and is rightly called as ‘king of fruits’ due to unique taste, flavour and is popular within all sections of society. Mango is cultivated vegetatively by adopting several techniques like inarching, budding, stone grafting but veneer grafti...
