“…The composition of the tree phyllosphere can vary considerably over longer time periods, with temporal variation on a given tree exceeding the variation in community composition among individual trees sampled on a given day, and can exhibit certain seasonal patterns [ 64 ]. Although there are other studies reporting different plant materials with different phyllosphere microbiota [ 22 , 65 ], little variation in bacterial community composition has been observed in different species of plants compared to other plant types [ 18 , 23 ]. According to Kim et al [ 66 ], the phylogeny of the host plant determines how similar the phyllosphere bacterial communities of these tree species are to one another, and more similar communities are found in closely related host plants.…”

“…The findings of one study revealed that the host species identity (27%) and species–site interaction (14%), location (11%), and season (1%) contribute to the variation in the composition of the phyllosphere bacterial population [ 22 ]. However, it has also been shown that the contribution of planting sites to the effect of phyllosphere microorganisms is stronger than that of varieties [ 23 ]. Although earlier research has revealed that phyllosphere communities are more complicated than previously thought, there are still many important issues to be resolved regarding their geographical and temporal variability [ 24 , 25 ].…”

“…Phyllosphere bacteria assembly drivers have been measured in earlier research [ 26 , 27 ], but the majority of these studies looked at only one possible driver of phyllosphere community structure. Additionally, prior research has concentrated on the study of microorganisms in a fixed part of the plant, such as the foliage [ 23 , 28 ] or rhizosphere [ 29 ]; however, studies on the effect of epiphytic bacteria on the plant as a whole are lacking.…”

Plant phyllosphere bacteria are vital for plant health and productivity and are affected by both abiotic and biotic factors. In this study, we surveyed the structure of the phyllosphere bacterial community associated with alfalfa. For two varieties of alfalfa, forty-eight samples of phyllosphere communities were collected at two locations over four seasons in 2020. Proteobacteria and actinobacteria were associated with the dominating phylum in the bacterial communities of the alfalfa phyllosphere. Sphingomonas was the most abundant genus-level bacteria, followed by Methylobacterium, Burkholderia-Caballeronia-Paraburkholderia, and Pseudomonas. Sampling time had a greater affect than site and variety on alfalfa surface microorganisms. The variation in phyllosphere bacterial community assembly was mostly explained by the season–site interaction (43%), season–variety interaction (35%), and season (28%). Variety, site–variety interaction, and season–site–variety interactions did not have a meaningful effect on phyllosphere bacterial diversity and community structure. The bacterial community in the phyllosphere of alfalfa showed seasonal changes over time. The environmental factors that contributed most to the phyllosphere bacterial community of alfalfa were temperature and sunshine duration, which were significantly positively correlated with most of the dominant bacterial genera in the alfalfa phyllosphere.

Fermentation process plays an important role in the biochemical properties and quality of cigar tobacco leaves (CTLs). In industry, exogenous additive (EA) was usually adopted for improving the quality of CTLs during fermentation. However, the mechanism of enhanced quality of CTLs fermented with EA was confused. Herein, the chemical compositions and microbial communities of CTLs during fermentation with EA were analyzed. The increased contents of total nitrogen and total sugar, as well as the improved consumption rate of reducing sugar in CTLs were found with the addition of EA. Besides, fermentation with EA reduced the content of total nonvolatile organic acid, especially unsaturated fatty acid. The contents of total and several representative aroma components were improved. Additionally, the increased abundance of Staphylococcus and decreased abundance of Aspergillus were detected. Combined with the changes of chemical compositions and microbial communities, it was confirmed that the carbohydrates and alcohols originated from EA promote the enrichment of Staphylococcus and accelerate biochemical reactions, such as Maillard reaction and esterification reaction, thus improving the contents and quality of aroma components in CTLs. This study demonstrated the mechanism of enhanced quality of CTLs fermented by EA, which provides more ideas for developing novel and efficient EAs.

“…Owing to the development of sequencing technology, a lot of work has been done recently focusing on the microbial community in this fermentation process. The high-throughput sequencing results suggested that bacterial community composition is brandrelated (Rooney et al, 2005;Chopyk et al, 2017;Smyth et al, 2017;Malayil et al, 2020), origin-related (Su et al, 2011;Yang et al, 2020;Xing et al, 2021;Ye et al, 2021) and fermentation process-related (Li et al, 2020;Zhang et al, 2020;Zhou et al, 2020Zhou et al, , 2021Liu et al, 2021). Recently, chattopadhyay et al overviewed the bacterial and fungal microbial communities in commercial tobacco products, and 89 unique bacterial genera and 19 fungal genera were identified in different tobacco products.…”

Cigar is made of a typical fermented tobacco where the microbiota inhabits within an alkaline environment. Our current understanding on cigar fermentation is far from thorough. This work employed both high-throughput sequencing and chromatography-mass spectrometric technologies to provide new scientific reference for this specific fermented system. Typical cigar samples from different regions (the Caribbeans, South America, East Asia, and Southeast Asia) were investigated. The results show that Firmicutes, Actinobacteria, Proteobacteria, Ascomycota, and Basidiomycota were the predominant phyla in the cigar samples. Rather than the fungal community, it was the bacterial community structures that played vital roles to differentiate the cigar from different regions: Staphylococcus was the dominant genus in the Americas; Bacillus was the dominant genus in Southeast Asia; while in East Asia, there was no dominant genus. Such differences in community structure then affected the microflora metabolism. The correlation between microbiota and metabolites revealed that Aspergillaceae, Cercospora, and Staphylococcus were significantly correlated with sclareolide; Bacillus were positively associated with isophorone. Alcaligenaceae was significantly and positively correlated with L-nicotine and hexadecanoic acid, methyl ester.GRAPHICAL ABSTRACT
