“…Species richness and environmental complexity are proved to increase ecosystem functioning [17]. Meanwhile, endophytes play an important role in ecological community by protection and survival value to the plants, such as enhancement of stress-, insect-and diseaseresistance, and growth promotion [11,14,20,21,28]. Therefore, we presume that the high richness and diversity of endophytic bacteria in R-R-MV are beneficial to the growth and productivity of rice.…”

“…The large amount of considerable the genus Cedecea was found in rice roots both in R-R-MV and R-R-WF rotations (20.8 and 8.9 %, respectively). The genus Cedecea is mostly isolated from human and animal bodies and was believed to be a possible pathogenic bacteria; until recently, two strains of Cedecea davisae were first reported by Silva et al [28] to have been isolated from plants and were first found to be able to inhibit coffee diseases, but there was no other report except for this one. This study firstly isolated the strains from rice roots as one of the major colonies, so its ecological function needs further research studies.…”

This study focuses on the effects of long-term rice rotated with milk vetch being as green manure on the composition of bacteria in rice roots. The endophytic bacterial communities in rice roots of the rice-rice-milk vetch (R-R-MV) and the rice-rice-winter fallow (R-R-WF) crop rotations with a 28-year research history were investigated using combined culture-dependent and culture-independent methods. It was found that the endophytic bacterial population in rice roots with the green manure was significantly higher than that of without it. There were 169 and 77 strains of endophytic bacteria that were isolated from rice roots of the R-R-MV and the R-R-WF, respectively. The 16S rRNA gene analysis shows that the 77 R-R-WF bacteria belong to 15 species of 14 genera while the other 169 R-R-MV bacteria belong to 21 species of 19 genera, in which Herbaspirillum and Cedecea were two mutually dominant populations and Burkholderia, Pseudomonas, Sphingomonas, and Pantoea accounted for large proportions of the endophytic bacteria in rice roots through R-R-MV rotation. The analysis of 16S rDNA clone libraries showed that the Shannon-Weaver diversity index of endophytic bacteria in R-R-MV approximates that in R-R-WF rotation, whereas the richness indexes of Chao 1 and ACE in R-R-MV rotation system were significantly higher than those in R-R-WF rotation. The diversity of endophytic bacteria was richer in R-R-MV. Both the culture-dependent and the cultureindependent method revealed significant effect of long-term different tillage systems on the microbial community.

“…Ochrobacterium, such as Ochrobactrum oryzae, might possess the ability to fix nitrogen [28] and Ochrobactrum anthropi promotes increased growth in the Jerusalem artichoke [29]. Stenotrophomonas, such as S. maltophilia, control Bipolaris sorokiniana in tall fescue [30], Paenibacillus, identified in pumpkin seeds, suppresses diseases, such as powdered mildew, also increasing harvest yields [31], and finally Microbacterium stimulate growth in Limonium sinense [32] and reduce the severity of leaf rust in coffee [33].…”

Guarana (Paullinia cupana var. sorbilis) is a plant from the Amazonas region with socio-economic importance. However, guarana production has been increasingly affected by unfavorable conditions resulting from anthracnose, caused by the Colletotrichum fungal genus, which primarily affects mainly the Amazonas region. The aim of the present study was to isolate bacterial endophytes from the seeds of guarana plants obtained from Amazonas region and the Northeast state of Bahia, a region where this disease is not a problem for guarana plantations. The number of bacterial Colony Forming Units (CFU/g seeds) was 2.4 × 10(4) from the Bahia and 2.9 × 10(4) from the Amazonas region. One hundred and two isolated bacteria were evaluated in vitro against the phytopathogenic strain Colletotrichum gloeosporioides L1. These isolates were also analyzed for the enzymatic production of amylase, cellulase, protease, pectinase, lipase and esterase. Approximately 15% of isolates, showing high antagonistic activity, and the production of at least one enzyme were identified through the partial sequencing of 16S rDNA. The genus Bacillus was the most frequently observed, followed by Paenibacillus, Ochrobactrum, Microbacterium and Stenotrophomonas. Proteolytic activity was observed in 24 isolates followed by amylolytic, pectinolytic and cellulolytic activities. No esterase and lipase production was detected. Most of the isolates, showing antagonistic effects against C. gloeosporioides and high enzymatic activities, were isolated from the anthracnose-affected region. A biocontrol method using the endophytes from guarana seeds could be applied in the future, as these bacteria are vertically transferred to guarana seedlings.

“…While some have examined epiphytic microbial communities (82), many have focused on endophytes from coffee tissues (50,52,83). Endophytes have been known for their ability to confer increased pest resistance (84,85), resistance to herbivory (86), and tolerance of environmental stress (87). With regard to disease resistance, both bacterial endophytes (88,89) and fungal endophytes (85) have been explored as agents to promote resistance to the coffee leaf rust pathogen.…”

bCoffee is a critically important agricultural commodity for many tropical states and is a beverage enjoyed by millions of people worldwide. Recent concerns over the sustainability of coffee production have prompted investigations of the coffee microbiome as a tool to improve crop health and bean quality. This review synthesizes literature informing our knowledge of the coffee microbiome, with an emphasis on applications of fruit-and seed-associated microbes in coffee production and processing. A comprehensive inventory of microbial species cited in association with coffee fruits and seeds is presented as reference tool for researchers investigating coffee-microbe associations. It concludes with a discussion of the approaches and techniques that provide a path forward to improve our understanding of the coffee microbiome and its utility, as a whole and as individual components, to help ensure the future sustainability of coffee production.
