“…Consistent with the results of the present study, Barretti et al (2009) isolated Acinetobacter johnsonii among endophytes from the tomato plant and showed this species to cause a significant decrease in the severity of the bacterial speck caused by Pseudomonas syringae. The genus Acinetobacter was also isolated as an endophyte in studies by Procópio et al (2009).…”

ABSTRACT. 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 & Waldy Cati 30) of acerola, and to evaluate their biotechnological ability by assessing their in vitro control of pathogenic fungi and the enzymatic production of cellulase, xylanase, amylase, pectinase, protease, lipase, esterase, and chitinase. In total, 157 endophytic bacteria were isolated from the leaves of two varieties of the plant at 28° and 37°C. Phylogenetic analysis confirmed the molecular identification of 58 bacteria, 39.65% of which were identified at the species level. For the first time, the genus Aureimonas was highlighted as an endophytic bacterium. Furthermore, 12.82% of the isolates inhibited the growth of all phytopathogens evaluated and at least one of the above-mentioned enzymes was produced by 64.70% of the endophytes, demonstrating that M. emarginata isolates have potential use in biotechnological studies.

“…The main objective of the study was to select bacteria from the plants following analysis of diversity, and then select endophytic strains with promising potential for biocontrol, and bacteria that stimulate the growth of the plant (Barretti et al, 2009;López-López et al, 2010;Montañez et al, 2012).…”

ABSTRACT. Because of human population growth, increased food production and alternatives to conventional methods of biocontrol and development of plants such as the use of endophytic bacteria and fungi are required. One of the methods used to study microorganism diversity is sequencing of the 16S rRNA gene, which has several advantages, including universality, size, and availability of databases for comparison. The objective of this study was to analyze endophytic bacterial diversity in agricultural crops using published papers, sequence databases, and phylogenetic analysis. Fourteen papers were selected in which the ribosomal 16S rRNA gene was used to identify endophytic bacteria, in important agricultural crops, such as coffee, sugar cane, beans, corn, soybean, tomatoes, and grapes, located in different geographical regions (America, Europe, and Asia). The corresponding 16S rRNA gene sequences were selected from the NCBI database, aligned using the Mega 5.2 program, and phylogenetic analysis was undertaken. The most common orders present in the analyzed cultures were Bacillales, Enterobacteriales, and Actinomycetales and the most frequently observed genera were Bacillus, Pseudomonas, and Microbacterium. Phylogenetic analysis showed that only approximately 1.56% of the total sequences were not properly grouped, demonstrating reliability in the identification of microorganisms. This study identified the main genera found in endophytic bacterial cultures from plants, providing data for future studies on improving plant agriculture, biotechnology, endophytic bacterium prospecting, and to help understand relationships between endophytic bacteria and their interactions with plants.

“…Three weeks after inoculation of endophytic fungi, re-isolation of each endophyte was done for confirmation of colonization. For this the few plants were uprooted from the treated plants and re-isolation was made by using same protocol for isolation of endophytes as previously reported by Miles et al (2012) and Barretti et al (2009).…”
