So far, the relative importance of the plant and its microbiome in the development of early stages of plant seedling growth under arsenic stress has not been studied. To test the role of endophytic bacteria in increasing plant success under arsenic stress, gnotobiotic seeds of J. montana were inoculated with two endophytic bacteria: Pantoea conspicua MC-K1 (PGPB and As resistant bacteria) and Arthrobacter sp. MC-D3A (non-helper and non-As resistant bacteria) and an endobacteria mixture. In holobiotic seedlings (with seed-vectored microbes intact), neither the capacity of germination nor development of roots and lateral hairs was affected at 125 μM As(V). However, in gnotobiotic seedlings, the plants are negatively impacted by absence of a microbiome and presence of arsenic, resulting in reduced growth of roots and root hairs. The inoculation of a single PGPB (P. conspicua-MCK1) shows a tendency to the recovery of the plant, both in arsenic enriched and arsenic-free media, while the inoculation with Arthrobacter sp. does not help in the recovery of the plants. Inoculation with a bacterial mixture allows recovery of plants in arsenic free media; however, plants did not recover under arsenic stress, probably because of a bacterial interaction in the mixture.

Tremendous Impact

Endophytes belong to a widespread group of microorganisms that colonise intracellular and intercellular spaces in all known plant parts but do not cause diseases or major morphological changes to the host. Endophytic bacteria ubiquitously colonise plant internal tissues, where they can form a variety of interactions, including commensalistic, symbiotic, trophobiotic and mutualistic. Endophytic bacteria produce pharmaceutically important compounds such as antimicrobials, antioxidants, industrial enzymes, antidiabetics and anti-cancer agents. In addition, endophytes can also support their host by producing a variety of natural products for potential use in medicine, agriculture or industry. This group of bacteria can have a tremendous impact on plant communities, raising their fitness by endowing tolerance to biotic and abiotic stress. There are great prospects for searching, selecting and studying new endophytic bacteria species in order to create new microbial preparations for adaptive crop production, while reducing the environmental impacts of agriculture. The present review summarises studies to date about endophytic bacteria, including topics such as isolation methods, the diversity of these bacteria and their biological roles.

The Development Strategy

Diseases annually cause significant crop losses and reduced quality of agricultural products. The development strategy of new environmentally friendly plant protection products should consider the role of the microbiome in host defense.

Invertebrate Pests

In 1991, a survey was distributed to 251 potato growers in South Australia to determine major diseases, insect and other invertebrate pests, and chemicals used to control them. The overall response rate was 48%, but of these, 24 individuals were no longer growing potatoes. The results were summarised for the State and by district (Adelaide Hills, Adelaide Plains, Murray Lands, South East). The most prevalent diseases encountered by respondents in all districts were target spot caused by Alternaria solani, and rhizoctonia canker caused by Rhizoctonia solani. Other diseases of concern to growers included late blight caused by Phytophthora infestans, seed piece decay caused by various pathogenic and saprophytic microorganisms, common scab caused by Streptomyces scabies, and leaf roll caused by potato leaf roll virus. The most commonly used fungicides for disease control were chlorothalonil (33-42% of respondents), mancozeb (30%), and cupric hydroxide (11-13%). The most commonly used seed treatments for control of seed piece decay were mancozeb (51 % of respondents), tolclofos methyl (24%), and lime (20%). Green peach aphid (Myzus persicae), potato aphid (Macrosiphum euphorbiae), potato moth (Phthorimaea operculella), and jassids and leafhoppers (Jassidae, Cicadellidae) were the pests of greatest concern to the growers. Others included Rutherglen bug (Nysius vinitor), redlegged earth mite (Halotydeus destructor), and thrips (Thripidae). The most commonly used insecticides were ethamidophos (40% of respondents), monocrotophos (22-28%), and dimethoate (7-13%).
