“…Wheat (Triticum spp.) seedlings inoculated with the pathogenic fungus Bipolaris sorokiniana showed a significant reduction of infection from 90.8 to 27.7%, including an increase in dry weight, root and shoot length, which indicates the dual function and potential of this desert PGPB as a bio-fertilizer and biocontrol agent (Allali et al, 2019).…”

“…Furthermore, this PLT2 strain showed strong antagonistic activity against the soil-borne pathogenic fungus Rhizoctonia solani, revealing the potential use of this desert PGPR as a biocontrol agent, which could help various crop plants against plant pathogens (Zamoum et al, 2017). In addition, Nocardiopsis dassonvillei MB22 with a strong biocontrol activity was isolated from the Saharan soils and showed several PGP traits including the production of IAA, HCN, and phosphate solubilization (Allali et al, 2019). Wheat (Triticum spp.)…”

Desert Microbes for Boosting Sustainable Agriculture in Extreme Environments

A large portion of the earth's surface consists of arid, semi-arid and hyper-arid lands. Life in these regions is profoundly challenged by harsh environmental conditions of water limitation, high levels of solar radiation and temperature fluctuations, along with soil salinity and nutrient deficiency, which have serious consequences on plant growth and survival. In recent years, plants that grow in such extreme environments and their naturally associated beneficial microbes have attracted increased interest. The rhizosphere, rhizosheath, endosphere, and phyllosphere of desert plants display a perfect niche for isolating novel microbes. They are well adapted to extreme environments and offer an unexploited reservoir for bio-fertilizers and bio-control agents against a wide range of abiotic and biotic stresses that endanger diverse agricultural ecosystems. Their properties can be used to improve soil fertility, increase plant tolerance to various environmental stresses and crop productivity as well as benefit human health and provide enough food for a growing human population in an environment-friendly manner. Several initiatives were launched to discover the possibility of using beneficial microbes. In this review, we will be describing the efforts to explore the bacterial diversity associated with desert plants in the arid, semi-arid, and hyper-arid regions, highlighting the latest discoveries and applications of plant growth promoting bacteria from the most studied deserts around the world.

“…The use of the endophytic bacterium Pseudomonas mediterranea resulted in a significant reduction in root and crown rot of wheat in Pakistan ( Ullah et al., 2020 ). Disease severity index of wheat common root rot decreased from 90.8% to 27.7% following the use of the actinobacterium Nocardiopsis dassonvillei as a biocontrol agent, which was attributed to the ability of this isolate to produce siderophores and hydrogen cyanide ( Allali et al., 2019 ). The actinobacterium was also found to enhance growth of wheat through the production of indole-3-acetic acid.…”

Wheat is among the ten top and most widely grown crops in the world. Several diseases cause losses in wheat production in different parts of the world. Bipolaris sorokiniana (teleomorph, Cochliobolus sativus) is one of the wheat pathogens that can attack all wheat parts, including seeds, roots, shoots, and leaves. Black point, root rot, crown rot and spot blotch are the main diseases caused by B. sorokiniana in wheat. Seed infection by B. sorokiniana can result in black point disease, reducing seed quality and seed germination and is considered a main source of inoculum for diseases such as common root rot and spot blotch. Root rot and crown rot diseases, which result from soil-borne or seed-borne inoculum, can result in yield losses in wheat. Spot blotch disease affects wheat in different parts of the world and cause significant losses in grain yield. This review paper summarizes the latest findings on B. sorokiniana, with a specific emphasis on management using genetic, chemical, cultural, and biological control measures.

“…As far as we know, among the 46 species of actinobacteria in this study, many species reportedly promote plant growth. For example, Nocardiopsis dassonoillei and Streptomyces violaceoruber can promote wheat and pepper seedling growth, respectively ( Sang et al, 2013 ; Allali et al, 2019 ).…”

“…Evidence has shown that the root-associated actinobacteria contribute to plant growth promotion ( Dutta & Thakur, 2020 ), and plant stress alleviation ( Esmaeil Zade, Sadeghi & Moradi, 2018 ; Selim et al, 2019 ), through diverse mechanisms such as indole-3-acetic acid (IAA) biosynthesis, siderophore production, and phosphate solubilization. Studies have investigated the impact of actinobacteria on plant growth promotion and seed germination rate improvement ( Zamoum et al, 2015 ; Allali et al, 2019 ; Borah & Thakur, 2020 ). Also, actinobacteria ability to mitigate the negative impact of abiotic stress on the growth and physiology of crops, such as wheat ( Yandigeri et al., 2012 ; Li et al, 2019 ), maize ( Warrad et al, 2020 ), tomato ( Abbasi, Sadeghi & Safaie, 2020 ) has been investigated.…”

Diversity and function of culturable actinobacteria in the root-associated of Salvia miltiorrhiza Bunge

The root-associated actinobacteria play important roles in plant growth, nutrient use, and disease resistance due to their functional diversity. Salvia miltiorrhiza is a critical medicinal plant in China. The root actinobacterial community structure has been studied; however, the functions of root-associated actinobacteria of S. miltiorrhiza have not been elucidated. This study aimed to decipher the diversity and function of the culturable root-associated actinobacteria in plant growth using culture-dependent technology and culturable microbe metagenomes. We isolated 369 strains from the root-associated actinobacteria, belonging to four genera, among which Streptomyces was dominant. Besides, the functional prediction revealed some pathways related to plant growth, nitrogen and phosphorus metabolism, and antagonistic pathogens. We systematically described the diversity and functions of the culturable root-associated actinobacteria community. Our results demonstrated that the culturable root-associated actinobacteria of S. miltiorrhiza have rich functionalities, explaining the possible contribution of culturable root-associated actinobacteria to S. miltiorrhiza’s growth and development. This study provides new insights into understanding the function of the culturable root-associated actinobacteria and can be used as a knowledge base for plant growth promoters and biological control agent development in agriculture.
