AbstractHalophytes have evolved several strategies to survive in saline environments; however, additional support from their associated microbiota could help combat adverse conditions. Endophytic communities of halophytes may be different than those in other plants because salinity acts as an environmental filter. At the same time, they may contribute to the host’s adaptation to adverse environmental conditions and can improve host tolerance against various biotic and abiotic stresses, which may be of importance in modern and sustainable agriculture.In this study the culturable endophytic bacteria of three halophytic species Cakile maritima, Matthiola tricuspidata and Crithmum maritimum were isolated and identified. Endophytic bacteria were isolated from roots and leaves of the sampled plants. Significant differences were observed in bacterial species abundance among different plant species and tissue from which the isolates were obtained. In total, 115 strains were identified by analysis of complete 16S rDNA sequences, while the majority of these isolates were derived from the root samples.The strains were evaluated for their ability to: 1) grow in-vitro in high levels of NaCl; 2) inhibit the growth of the economically important plant pathogenic fungus Verticillium dahliae in vitro and in planta, the human pathogenic fungus Aspergillus fumigatus in vitro, as well as, the economically important plant bacterial pathogens Ralstonia solanacearum and Clavibacter michiganensis in vitro; 3) provide salt tolerance in planta; 4) provide growth promoting effect in planta.Additionally, the genomes of twelve selected isolates, exhibiting interesting features, were sequenced and analysed. Three novel bacterial species were identified that belong to the genus Pseudomonas (two strains) and Arthrobacter (one strain).The outcome of our study is the proof-of-concept that the crop wild relatives (CWR) halophytic microbiome could potentially serve as a source of beneficial microorganisms that could be used (as unique species or as artificial communities) as Bio-Inoculants, for the enhancement of plant growth and stress tolerance in crops, including the high-salinity stress.This is very important in the era of ecosystem degradation and climate change, where the maximizing microbial functions in agroecosystems could be a prerequisite for the future of global sustainable agriculture. Globally, there is a strong need for the identification and bio-banking of novel beneficial endophytic microbes with as many desirable characters, for the development of a new environmentally friendly global strategy in food production that will be based in the sustainable agriculture with low chemical inputs and a low environmental impact.

Endophytic bacterial communities are beneficial communities for host plants that exist inside the surfaces of plant tissues, and their application improves plant growth. They benefit directly from the host plant by enhancing the nutrient amount of the plant’s intake and influencing the phytohormones, which are responsible for growth promotion and stress. Endophytic bacteria play an important role in plant-growth promotion (PGP) by regulating the indirect mechanism targeting pest and pathogens through hydrolytic enzymes, antibiotics, biocontrol potential, and nutrient restriction for pathogens. To attain these benefits, firstly bacterial communities must be colonized by plant tissues. The nature of colonization can be achieved by using a set of traits, including attachment behavior and motility speed, degradation of plant polymers, and plant defense evasion. The diversity of bacterial endophytes colonization depends on various factors, such as plants’ relationship with environmental factors. Generally, each endophytic bacteria has a wide host range, and they are used as bio-inoculants in the form of synthetic applications for sustainable agriculture systems and to protect the environment from chemical hazards. This review discusses and explores the taxonomic distribution of endophytic bacteria associated with different genotypes of rice plants and their origin, movement, and mechanism of PGP. In addition, this review accentuates compressive meta data of endophytic bacteria communities associated with different genotypes of rice plants, retrieves their plant-growth-promoting properties and their antagonism against plant pathogens, and discusses the indication of endophytic bacterial flora in rice plant tissues using various methods. The future direction deepens the study of novel endophytic bacterial communities and their identification from rice plants through innovative techniques and their application for sustainable agriculture systems.

Chemical Inputs

The excessive use of synthetic chemical inputs in agricultural production has led to the disruption of biogeochemical cycles. One of the alternatives that arose within the systems of sustainable agriculture was the partial or total replacement of chemicals by biological substances. The analysis of relevant scientific literature has become a tool for assessing the quality of knowledge generation and its impact on the environment. A scientometric analysis was conducted of Colombian research on bio-inoculants from 2009 through 2014 in journals added to the Web of SciencesTM in order to identify the characteristics of the main target crops, the microorganisms used, and the beneficial effects on agriculture. In this work, 34 articles were identified: 24 (71%) were research on bio-fertilizer development and 10 (29%) on bio-pesticides. Articles mainly focused on the study of Gram-negative bacilli affecting the area (77%), while others focused on issues and topics surrounding vegetables (30%).The analysis of co-occurrence of keywords identified: i) several genera of microorganisms (e.g. Azotobacter Bradyrhizobium) and sustainable agriculture as issues that have a leading role in this scientific field, ii) plant growth promoting rhizobacteria (PGPR) as an emerging issue, iii) biological nitrogen fixation (BNF) as a subject which has risen in a complementary manner and iv) endophytic bacteria and biodiversity as issues in growth. This study showed that research in Colombia could be targeted on issues such as endophytic bacteria, diversity and productivity.
