- PublicaciónAcceso abiertoActinobacteria-enhanced plant growth, nutrient acquisition, and crop protection: Advances in soil, plant, and microbial multifactorial interactions(2022-02-05) Mitra, Debasis; MondaL, Rittick; Khoshru, Bahman; Senapati, Ansuman; Radha, T. K.; Mahakur, Bhaswatimayee; Uniyal, Navendra; Myo, Ei Mon; Boutaj, Hanane; Guerra-Sierra, Beatriz Elena; Panneerselvam, Periyasamy; Ganeshamurthy, Arakalagud Nanjundaiah; Andelković, Snežana; Vasić, Tanja; Rani, Anju; Dutta, Subhadeep; Das Mohapatra, Pradeep K.; MicrobiotaAgricultural areas of land are deteriorating every day owing to population increase, rapid urbanization, and industrialization. To feed today's huge populations, increased crop production is required from smaller areas, which warrants the continuous application of high doses of inorganic fertilizers to agricultural land. These cause damage to soil health and, therefore, nutrient imbalance conditions in arable soils. Under these conditions, the benefits of microbial inoculants (such as Actinobacteria) as replacements for harmful chemicals and promoting ecofriendly sustainable farming practices have been made clear through recent technological advances. There are multifunctional traits involved in the production of different types of bioactive compounds responsible for plant growth promotion, and the biocontrol of phytopathogens has reduced the use of chemical fertilizers and pesticides. There are some well-known groups of nitrogen-fixing Actinobacteria, such as Frankia, which undergo mutualism with plants and offer enhanced symbiotic trade-offs. In addition to nitrogen fixation, increasing availability of major plant nutrients in soil due to the solubilization of immobilized forms of phosphorus and potassium compounds, production of phytohormones, such as indole-3-acetic acid, indole-3-pyruvic acid, gibberellins, and cytokinins, improving organic matter decomposition by releasing cellulases, xylanase, glucanases, lipases, and proteases, and suppression of soil-borne pathogens by the production of siderophores, ammonia, hydrogen cyanide, and chitinase are important features of Actinobacteria useful for combating biotic and abiotic stresses in plants. The positive influence of Actinobacteria on soil fertility and plant health has motivated us to compile this review of important findings associated with sustaining plant productivity in the long run.
- PublicaciónAcceso abiertoArbuscular mycorrhizal fungal association boosted the arsenic resistance in crops with special responsiveness to rice plant(2022-01-05) Mitra, Debasis; Saritha, Boya; Janeeshma, Edappayil; Gusain, Poonam; Khoshru, Bahman; Abo Nouh, Fatma A.; Rani, Anju; Olatunbosun, Adeyemi N.; Ruparelia, Janki; Rabari, Aniruddh; Mosquera-Sánchez, Lyda P.; Mondal, Rittick; Verma, Devvret; Panneerselvam, Periyasamy; Das Mohapatra, Pradeep K.; Guerra-Sierra, Beatriz Elena; MicrobiotaArsenic (As) is a potentially toxic metalloid classified as a group 1 carcinogen, released in the soil environment because of natural as well as different anthropogenic activities. The presence of excess As content in soil and irrigation water enhances the As accumulation in rice grains. Millions of people who consume these contaminated grains are exposed to severe health issues. Increased arsenic uptake causes oxidative stress in plants, which combats by inducing the expression of several genes and signaling the biosynthesis of various antioxidants and phytochelatins. As toxicity reduces crop productivity, so it's critical to improve plant growth in As-contaminated environments while minimizing metal translocation to grains. Arbuscular mycorrhiza fungi (AMF) is considered a sustainable way to tolerate As toxicity. Organic pollutants metabolism by AMF, degradation of these soil contaminants by AMF exudation enzymes, and elimination of the pollutants by plant uptake and accumulation are the principal mechanisms of AMF mediated bioremediation. However, plant responses are established to vary with the host plant and the species of AMF. In our review, we showed that understanding the community composition, diversity, and gene regulation of AMF in the rice ecosystem played a critical role in maximizing As uptake and their potential in sustainable rice and other crops production. It has been reviewed that AMF has the potential to survive in an extremely As toxic condition and it potentially aids to improve the tolerance level of host plants.
- PublicaciónAcceso abiertoImpacts of Arbuscular Mycorrhizal Fungi on Rice Growth, Development, and Stress Management With a Particular Emphasis on Strigolactone Effects on Root Development(2021-03-15) Debasis, Mitra; Guerra Sierra, Beatriz Elena; Bahman, Khoshru; De Los Santos Villalobos, Sergio; Belz, Claudia; Chaudhary, Priya; Shahrig, Faride Noroozi; Rihab, Djebaili; Nurudeen, Olatunbosun Adeyemij; El-Ballatk, Enas M.; El-Esawik, Mohamed A.; Moradic, Shokufeh; Mondall, Rittick; Senapati, Ansuman; Panneerselvam, Periyasamy; Das Mohapatra, Pradeep K.; MicrobiotaArbuscular mycorrhizal fungi (AMF) are widely distributed soil-borne microorganisms, which have a symbiotic relationship with several terrestrial plants. They play a key role in plant growth promotion and development, plant nutrient homeostasis, soil nutrient management, and induction of plant defense mechanisms against pest infestation and disease incidences. This interaction of AMF with rice plants has been studied in great detail, providing distinct perspectives on the natural basis of nutrient transport, stress management, improvement of soil health, and induction of systemic plant resistance. This review highlights the responses of (i) AMF interaction with rice plants, (ii) AMF colonization and sporulation potential in rice rhizosphere, (iii) AMF species as a source of inoculum for rice production, (iv) AMF for rice plant maintenance and durability, and (v) AMF responses to other soil microorganisms. Additionally, a new class of phytohormones known as strigolactone (SLs) has been briefly described covering the various forms of analogs, isomers, and membrane transporters. The role of SLs in pre-symbiotic molecular talks, induction of energy metabolism in mitochondria, spore germination, stimulation of hyphal branches, and the relationships of SLs synthesis with soil nutrient content provides in-depth insights into the mechanisms involved in improving AMF interactions with rice plants.
