“…A potential option to increase the growth and yield of plants and reduce the destructive impact of chemical fertilizers on the environment can be the application of plant growth promoting bacteria (Krause et al, 2006). Beneficial properties of endophytes in increasing yields of agricultural crops, controlling plant diseases or pests, and adapting plants against stress conditions can encourage their increased application in sustainable agriculture practice (Mei and Flinn, 2010).…”

Pirhadi et al.: Impact of soil salinity on diversity and community of sugarcane endophytic plant growth promoting bacteria (Saccharum officinarum L. Abstract. The aim of this study was to isolate and identify culturable bacterial endophytes from sugarcane grown in saline and non-saline soil and assay some plant growth-related traits and evaluate selective isolate potential to improve growth, yield and grain phosphorus uptake of wheat. Endophytic bacteria associated with sugarcane grown in saline and non-saline soil were isolated from roots, stems and leave and tested for their ability to fix nitrogen, indole acetic acid (IAA) production and dissolution of insoluble phosphorus. A total of 55 endophytic bacteria were isolated from leaves, stems, and roots of sugarcane from saline and nonsaline soil. The results revealed a prevalence of Bacillaceae, with Bacillus sp. being the most frequently isolated bacterium. Salinity had the effect on bacterial community structure with the higher diversity of root entophytic bacteria in saline soils. From the isolates, four strains were shown to produce IAA and 19 strains showed the ability to solubilize phosphate, but twelve isolates having the best characteristics tests were identified using 16S rRNA gene sequencing. From the isolates Pseudomonas sp. SugS_49 with more phosphorus dissolution ability selected for evaluation on wheat growth. Application of Pseudomonas sp. SugS_49 caused increased growth, grain yield and phosphorus uptake of wheat.

Bacterial endophytes are a class of endosymbiotic microorganisms widespread among plants that colonize intercellular and intracellular spaces of all plant compartments and do not cause plant disease or significant morphological changes. Plant and endophytic bacteria association includes vast diversity of bacterial taxa and plant hosts and in this review we present an overview of taxonomic composition of endophytes identified in common agricultural crops. Further, during the last decade, new aspects of the microbial diversity have emerged with application of new metagenomic analysis methods in studies of bacterial endophytes. Endophytic bacteria community structure is influenced by plant genotype, abiotic and biotic factors such as environment conditions, microbe -microbe interactions and plant -microbe interactions. Agricultural practices, such as soil tillage, irrigation, use of pesticides and fertilizers have a major effect on function and structure of soil and endophytic microbial populations. Therefore, the use of agricultural practices that maintain natural diversity of plant endophytic bacteria is becoming an important element of sustainable agriculture that could ensure plant productivity and quality of agricultural production. The diverse endophytic microbial communities play integral and unique role in the functioning of agroecosystems. Endophytic bacteria have been shown to have several beneficial effects on their host plant, including growth promoting activity, modulation of plant metabolism and phytohormone signalling that leads to adaptation to environmental abiotic or biotic stress. Use of endophytic bacteria presents a special interest for development of agricultural applications that ensure improved crop performance under cold, draught or contaminated soil stress conditions or enhanced disease resistance.

Endophytic fungi have roles to protect the plant from herbivorous insects and diseases, and to support the absorption process of nutrients needed by plants for photosynthesis. Related to the important role of endophytic fungi, research was aimed to identify fungal endophytes associated with young, mature and old leaves on apple and to evaluate the effect of leaf ages on the abundance and diversity of endophytic fungi. The research was conducted in Biological Control Laboratory, Department of Plant Pests and Diseases, Faculty of Agriculture, Universitas Brawijaya from May to September 2016. Apple leaves sampling was done diagonally, and taken from nine apple trees. Based on macroscopic and microscopic characteristics, 38 isolates were identified. In the old apple leaves, it obtained 17 isolates that consisted of 5 genera, mature leaves obtained 14 isolates consisted of 6 genera, and young leaves 7 isolates obtained consists of 2 genera. The mature leaves have highest abundance and diversity of endophytic fungi compared to young and old leaves. Endophytic fungi apple leaf dominated by Aspergillus. Mature and young leaves were different from old one based on Bray-Curtis similarity.
