“…However, the phyla of these genera have also been reported many times in other sugarcane soil studies. Acidobacteria and Actinomycetes are also more common in sugarcane soils treated with nitrogen fertilizer [ 54 , 55 ]. Proteobacteria significantly increased in bagasse mulching sugarcane soil [ 14 ].…”

Organic fertilizers are critically important to soil fertility, microbial communities, and sustainable agricultural strategies. We compared the effect of two fertilizer groups (organic+chemical fertilizer: OM, chemical fertilizer: CK) on sugarcane growth, by observing the difference in microbial communities and functions, soil nutrient status, and agronomic characters of sugarcane. The results showed that the sugar content and yield of sugarcane increased significantly under organic fertilizer treatment. We believe that the increased soil nutrient status and soil microorganisms are the reasons for this phenomenon. In addition, redundancy analysis (RDA) shows that the soil nutrient condition has a major impact on the soil microbial community. In comparison with CK, the species richness of Acidobacteria, Proteobacteria, Chloroflexi, and Gemmatimonadetes as well as the functional abundance of nucleotide metabolism and energy metabolism increased significantly in the OM field. Moreover, compared with CK, genes related to the absorption and biosynthesis of sulfate were more prominent in OM. Therefore, consecutive organic fertilizer application could be an effective method in reference to sustainable production of sugarcane.

“…And several species of Methylobacterium have been reported as plant growth-promoting bacteria (PGPB) and Hg-resistant bacteria (Durand et al 2017;Antunes et al 2017;Grossi et al 2020). In addition, Tani et al (2015) found that Methylobacterium can not only use methanol emitted by plants as a carbon source and energy source, promote plant maturity, increase particle size, but also show super-strong species level on a given plant species Selection pressure is critical to achieving growth promotion.…”

High-throughput sequencing-based analysis of the composition and diversity of endophytic bacterial community in seeds of upland rice

Upland rice is an ecotype crop formed by long-term domestication and evolution of rice in the dry land without water layer. Generally, its stem and leaf are thick and luxuriant, its leaf is wide and light, its root system is developed, its root hair is abundant, its osmotic pressure of root and cell juice concentration of leaf are high, and it is drought resistant, heat-resistant and water absorbing. The purpose of this study is to reveal the "core flora" of endophytes in upland rice seeds by studying the diversity and community structure of endophytes in upland rice seeds, and to reveal the impact of soil environment on the formation of endophyte community structure in upland rice seeds by comparing with soil environment microorganisms in upland rice habitats. In this study, the high-throughput sequencing technology based on the Illumina Hiseq 2500 platform was used to study the structure and diversity of endophytic bacterial communities using upland rice varieties collected in different places and soil samples from their unified planting sites as materials. There are 42 endophytic OTUs coexisted in the 14 samples. At the phylum level, the first dominant phyla was Proteobacteria (93.81-99.99%) in all 14 samples. At the genus level, Pantoea (8.77%-87.77%), Pseudomonas (1.15-61.58%), Methylobacterium (0.40-4.64%), Sphingomonas (0.26-3.85%), Microbacterium (0.01-4.67%) and Aurantimonas (0.04-4.34%), which are probably the core microflora in upland rice seeds, served as the dominant genera that coexisted in all upland rice seeds tested. Compared with the soil microbial community structure in the upland rice uniform planting site, it was found that it had little effect on the endophytic community structure in upland rice seeds. This study is of great significance for the isolation, screening, functional evaluation and reaction of some functional microorganisms in upland rice in order to improve its agronomic traits. It also provides a certain reference for the interaction between microorganisms and plants. the adjacent plant tissues. Therefore, endophytes are ubiquitous in the plant host, including the aboveground and underground parts of the plant, even seeds, thus having a positive impact on the plant development (Zinniel et al. 2015; Chebotar et al. 2015). Endophytes can provide a variety of benefits to host plants, especially through multiple functions to improve the growth and health of plants, so that they can be protected from pathogens (Agler et al. 2016; Liu et al. 2017a,b; Xu et al. 2019; Afzal et al. 2019; Sánchez-Cruz et al. 2019). Under different environmental conditions, the communication and interaction between endophyte and plant is stronger than that between rhizosphere bacteria (Coutinho et al. 2015). A number of studies have shown that plant varieties, genotypes and geographical location have a great impact on the establishment of microbial diversity and community structure in plants (Liu et al. 2017a, 2019; Edwards et al. 2015). Although endophyte was discovered more than 100 years ago, its existe...

“…The promotion of plant growth by PGPB is already known and it involves, among others, biochemical capabilities, production of phytohormones such as indole-3-acetic acid (IAA) and the process of biological nitrogen fixation (Souza et al 2015). Indeed, these PGPB isolates presented a high capability of producing IAA and performing the biological N fixation in sugarcane (Antunes et al 2017), and could also promote the maize and sorghum growth. Previous studies have shown positive growth responses in maize and sorghum, when inoculated with PGPB (Schlemper et al.…”

“…The study was conducted at the Universidade Federal do Piauí, in Teresina, Piauí state, Brazil, from March to June 2018. A total of 40 PGPB isolates (Table 1), obtained in leaves and stalks of sugarcane by Antunes et al (2017), were inoculated into seeds of sorghum (Sorghum bicolor cv. Palo Alto N52K1009) and maize (Zea mays cv.…”

Plant growth-promoting bacteria (PGPB) are found in plant tissues and promote plant growth by secretion of hormones and enzymes, or by facilitating the nutrient uptake. This study assessed forty PGPB isolates to determine their effects on maize and sorghum growth. These isolates were also compared with uninoculated plants, as negative (-N; without N fertilization) and positive (+N; with N fertilization) controls. Plant height, stem diameter, shoot and root dry mass, leaf N accumulation and chlorophyll content were evaluated. For both the maize and sorghum, the height, stem diameter and shoot dry mass in plants inoculated with PGPB were similar to those of uninoculated plants supplied with N, and the responses for root mass were higher than in plants supplied with N. However, the PGPB isolates did not promote N accumulation and chlorophyll content similar to those of uninoculated plants supplied with N. The IPACC26 and IPACC30 isolates, both identified as Bacillus subtilis, resulted in better responses for plant growth and N accumulation than the other isolates.
