INTRODUCTION OF SOME NEW ARBUSCULAR-MYCORRHIZAL FUNGI (AMF) FROM CITRUS RHIZOSPHERE OF IRAN

During 2001-2002, a total number of 164 soil-root samples were collected from citrus orchards of six provinces, namely, Fars, Gilan, Mazandaran, Kerman, Hormozgan and Sistan va Baloochestan. Soil samples were decanted and centrifuged and spores were collected and examined. Out of 23 identified species, five species were recognized new to Iran mycoflora. New species are as follows: Gomus albidum...

Biodiversity of arbuscular mycorrhizal fungi in agroecosystems

Arbuscular mycorrhizal fungi [AMF] are soil fungi which form a mutualistic symbiosis with the roots of plants. A variety of benefits to the host have been ascribed to mycorrhizae, most often enhanced uptake of immobile nutrients from the soil, notably P. An understanding of the impacts of agronomic practices upon communities of these fungi would help to ensure an opportunity for the utilization...

DNA barcoding of arbuscular mycorrhizal fungi.

SUMMARY *Currently, no official DNA barcode region is defined for the Fungi. The COX1 gene DNA barcode is difficult to apply. The internal transcribed spacer (ITS) region has been suggested as a primary barcode candidate, but for arbuscular mycorrhizal fungi (AMF; Glomeromycota) the region is exceptionably variable and does not resolve closely related species. *DNA barcoding analyses were perfo...

Meiotic genes in the arbuscular mycorrhizal fungi

The arbuscular mycorrhizal fungi (AMF) are important symbionts of land plants, which are known for their tremendous positive effects on terrestrial ecosystems, their peculiar cellular features, and their very old evolutionary history. To date, no sexual stage or apparatus have ever been observed in these organisms; a remarkable absence for a eukaryotic lineage. For this reason, AMF have long be...

Arbuscular Mycorrhizal Fungi and Alien Plant Species

The invasion success of alien plant species depends, amongst other things, on their functional traits [4] and the susceptibility of ecosystems. There is now increasing interest in including biotic interactions particularly mutualistic associations [5], into frameworks assessing alien plant invasions, as they help bridge the invisibility and invasiveness features. The great majority of terrestri...
