Endophytic fungi reduce leaf-cutting ant damage to seedlings.
Our study examines how the mutualism between Atta colombica leaf-cutting ants and their cultivated fungus is influenced by the presence of diverse foliar endophytic fungi (endophytes) at high densities in tropical leaf tissues. We conducted laboratory choice trials in which ant colonies chose between Cordia alliodora seedlings with high (E(high)) or low (E(low)) densities of endophytes. The E(h...
متن کاملTwo fungal symbioses collide: endophytic fungi are not welcome in leaf-cutting ant gardens.
Interactions among the component members of different symbioses are not well studied. For example, leaf-cutting ants maintain an obligate symbiosis with their fungal garden, while the leaf material they provide to their garden is usually filled with endophytic fungi. The ants and their cultivar may interact with hundreds of endophytic fungal species, yet little is known about these interactions...
متن کاملSpecificity and transmission mosaic of ant nest-wall fungi.
Mutualism, whereby species interact to their mutual benefit, is extraordinary in a competitive world. To recognize general patterns of origin and maintenance from the plethora of mutualistic associations proves a persisting challenge. The simplest situation is believed to be that of a single mutualist specific to a single host, vertically transmitted from one host generation to the next. We cha...
متن کاملAntifungal activity of recombinant rice LTP2 on some phytopathogenic fungi
Plant lipid transfer proteins (LTPs) are members of the pathogenesis-related proteins (PR-14) and some of them exhibit activity against phytopathogenic fungi. To investigate whether rice LTP2 plays a role in antifungal activity, the coding region of an Iranian rice Ltp2 gene was cloned into expression vector pET24-d(+) and then expressed in Escherichia coli Rosetta strain (DE3). The potential a...
متن کاملVirulence regulation of phytopathogenic fungi by pH.
SIGNIFICANCE Postharvest pathogens can start its attack process immediately after spores land on wounded tissue, whereas other pathogens can forcibly breach the unripe fruit cuticle and then remain quiescent for months until fruit ripens and then cause major losses. RECENT ADVANCES Postharvest fungal pathogens activate their development by secreting organic acids or ammonia that acidify or al...
