MPCM and SBFSEM phenotyping of rice mutants compromised in arbuscule development will provide a novel insight into the complex molecular mechanisms that underpin cellular morphogenesis during plant endosymbiosis.
Arbuscule represents a dead end in the growth of AM fungi (Bonfante 1995) as they senesce and collapse after 4-10 days of symbiosis (Sanders 1977) and thus the plant cell recovers its original morphology (Jacquelinet-Jeanmougin 1987).
The microscope was focused through the entire root segment and if an arbuscule or vesicle was detected, the root segment at the intersection was scored as infected.
2010) recorded highest AM colonization (M = 78%) and arbuscule richness (A = 76%) in Thelypteris patens (Sw.
If an arbuscule or vesicle was found at an intersect, that intersect was considered infected.
Arbuscule abundance (A%) is an estimate of arbuscule richness in the whole root system (Trouvelot et al.
Moreover, it should also be noted that the number of arbuscules present in the arid climate is sometimes more important than in sub-humid climate, this demonstrates the importance of endomycorrhizae role, especially arbuscules that represent sites of functional exchanges between the endomycorrhizal fungus and roots of the host plant [17].
Roots were observed under a dissecting microscope and scored for presence or absence of hyphae, vesicles, or arbuscules along the root--grid-line intersects.
Root colonisation by AM fungi was defined by the presence of arbuscules and hyphae within roots and expressed as percentage of root length; 6 repeated measurements were taken on each sample, redispersing the sample between each measurement.
