Acerola; Antagonistic activity; Endophytes; Enzymes; Phylogenetic analysis

Acerola (Malpighia emarginata) is a shrub native to tropical and subtropical climates, which has great commercial interest due to the high vitamin C content of its fruit. However, there are no reports of the endophytic community of this plant species. The aim of this study was to verify the genetic diversity of the leaf endophytic bacterial community of two varieties (Olivier ... more

Bacterial diversity; Endophytes; Mexican husk tomato plants; Rhizosphere

Endophytic bacterial diversity was estimated in Mexican husk tomato plant roots by amplified rDNA restriction analysis and se­quence homology comparison of the 16S rDNA genes. Sixteen opera­tional taxonomic units from the 16S rDNA root library were identified based on sequence analysis, including the classes Gammaproteobacte­ria, Betaproteobacteria, Actinobacteria, and Bacilli. The ... more

Antagonism; ARDRA; Diversity; Endophytes; Fungal inhibition; Grape

We investigated the diversity of endophytic fungi found on grape (Vitis labrusca cv. Niagara Rosada) leaves collected from Salesópolis, SP, Brazil. The fungi were isolated and characterized by amplified ribosomal DNA restriction analysis, followed by sequencing of the ITS1-5.8S-ITS2 rDNA. In addition, the ability of these endophytic fungi to inhibit the grapevine pathogen ... more

Endophytes; Meliaceae; Molecular identification; rDNA sequencing; Trichilia

Various types of organisms, mainly fungi and bacteria, live within vegetal organs and tissues, without causing damage to the plant. These microorganisms, which are called endophytes, can be useful for biological control and plant growth promotion; bioactive compounds from these organisms may have medical and pharmaceutical applications. Trichilia elegans (Meliaceae) is a native ... more

Endophytes; Molecular identification; Phylogeny; Piperaceae; rDNA sequencing

Tropical and subtropical plants are rich in endophytic community diversity. Endophytes, mainly fungi and bacteria, inhabit the healthy plant tissues without causing any damage to the hosts. These fungi can be useful for biological control of pathogens and plant growth promotion. Some plants of the genus Piper are hosts of endophytic microorganisms; however, there is little ... more

Aquatic macrophytes; Endophytes; Molecular identification; Phylogeny

Endophytic fungi live in the interior of healthy plants without causing them any damage. These fungi are of biotechnological interest; they may be used in the biological control of pests and plant diseases, and in the pharmaceutical industry. The aquatic macrophytes Eichhornia azurea (Kunth) and Eichhornia crassipes (Mart.) belong to the Pontederiaceae family. The first ... more

In the present study, we demonstrated the in vitro activity of endophytic phosphate-solubilizing bacteria (PSB). Fifty-five endophytic PSB that were isolated from sap, leaves, and roots of maize were tested for their ability to solubilize tricalcium phosphate and produce organic acid. Partial sequencing of the 16S rRNA-encoding gene showed that the isolates were from the genus Bacillus and ... more

Marine bacteria have been exceptional sources of halotolerant enzymes since decades. The aim of the present study was to isolate bacteria producing hydrolytic enzymes from seven different mangroves collected from the coastal area of Thuwal, Jeddah, Saudi Arabia, and to further screen them for other enzymatic and antifungal activities. We have isolated 46 different rhizo- and endophytic ... more

Fungi; Mitochondrial plasmids; Molecular phylogeny; Moniliophthora perniciosa

The filamentous fungus Moniliophthora perniciosa is a hemibiotrophic basidiomycete that causes witches’ broom disease of cacao (Theobroma cacao L.). Many fungal mitochondrial plasmids are DNA and RNA polymerase-encoding invertrons with terminal inverted repeats and 5'-linked proteins. The aim of this study was to carry out comparative and phylogenetic analyses of DNA and ... more

To date, research on laccases has mostly been focused on plant and fungal laccases and their current use in biotechnological applications. In contrast, little is known about laccases from plant pathogens, although recent rapid progress in whole genome sequencing of an increasing number of organisms has facilitated their identification and ascertainment of their origins. In this study, a ... more
