Strigolactones, recently discovered as plant hormones, regulate the development of different plant parts. In the root, they regulate root architecture and affect root hair length and density. Their biosynthesis and exudation increase under low phosphate levels, and they are associated with root responses to these conditions. Their signaling pathway in the plant includes protein interactions and...

A greenhouse experiment was conducted in order to evaluate the efficiency of seven Arbuscular Mycorrhizal Fungi (AMF) namely, Acaulospora deligata, Glomus aggregatum, G feugianum, G fasciculatum, G rubiforme, Gigaspora margarita, and Scutellospora heterogama collected from the rhizosphere soils of Wedilia chinensis (Osbeck) Merril. They were evaluated on the same host for improvement of phytoch...

An investigation has been made about the vesicular arbuscular mycorrhizal fungi colonization in some medicinal plants Catharanthus roseus, C. pusillus, Wrightia tinctoria, Thevetia peruviana, Nerium indicum and Alstonia scholaris belongs to family Apocyanaceae were screened for the occurrence and association of VA mycorrhizal fungi. All the plants screened in the study harbored VA mycorrhizal f...

Exudates of Rhodotorula mucilaginosa, a yeast commonly found in the rhizosphere, increased hyphal length of the arbuscular mycorrhizal (AM) fungi Gigaspora rosea and Gigaspora margarita. Rhodotorulic acid (RA), a siderophore compound obtained from R. mucilaginosa exudates, increased hyphal length and branching. Thus, the increase in the number of entry points and the higher AM root colonization...
