“…The inoculation of some cytokinin-producing microorganisms can increase cytokinin content and enhance drought tolerance. For example, the inoculation of osmotolerant cytokinin producing microbes can increase the yield of tomato by improving the photosynthetic index and relative water content of plants under drought stress [146]. Inoculation of Methylobacterium oryzae into lentil results in significant improvement in the growth performance of plants exposed to drought, including early seedling growth, and improvement of the harvest index [147].…”

Cytokinins promote plant growth and development under normal plant growth conditions and also play an important role in plant resistance to stress. Understanding the working mechanisms of cytokinins under adverse conditions will help to make full use of cytokinins in agriculture to increase production and efficiency of land use. In this article, we review the progress that has been made in cytokinin research in plant response to stress and propose its future application prospects.

Vanilla planifolia Jacks. is a species of great economic importance, since vanillin, a compound highly valued in the food and pharmaceutical industry, is extracted from its pods. This species is in the category of special protection, so it is important to take actions for its conservation and to maintain the genetic stability of the conserved germplasm. An adequate way to achieve this is through the minimal growth in vitro conservation techniques. The present work aimed to establish an in vitro conservation protocol for vanilla germplasm that allows the genetic stability of the conserved material. For the establishment of the minimal growth in vitro conservation protocol: two concentrations of basal Murashige and Skoog (MS) medium (50% and 100%), two incubation temperatures (4 and 22 °C) and two concentrations of abscisic acid (ABA) (3 and 5 mg⋅L−1) were evaluated. To evaluate the genetic stability of the germplasms used in this study (cultivated, wild, and V. insignis morphotypes) by analyzing the profiles of molecular markers SSR (simple sequence repeats) and ISSR (inter simple sequence repeats). The MS medium (100%) supplemented with 3 mg⋅L−1 of ABA and incubated at 22 °C, was the best treatment for the in vitro conservation of Vanilla spp. Compared with the control treatment, it allowed us to obtain smaller shoots (1.17 × 0.17 cm), which showed high genetic stability, given by the low percentages of polymorphism detected in morphotypes cultivated and wild (SSR 0%, ISSR 2%) and V. insignis (SSR 0%, ISSR 0%). We conclude the usefulness of the established protocol to conserve the genetic variation of the evaluated Vanilla germplasm.

“…Exogenously, this hormone is produced by microbes. Bacillus subtilis (Kudoyarova et al 2014;Liu et al 2013), Pseudomonas syringae (Großkinsky et al 2016), Citrococcus zhacaiensis, and Bacillus amyloliquefaciens (Selvakumar et al 2018) are cytokinin producing soil bacteria reported so far.…”

Soil microbial diversity is very important part of ecosystem as it plays a significant role in biogeochemical cycles. Currently, health of environment has been depleted due to growing population of the world and human activities like industrialization, overexploitation of chemical based products in agriculture and urbanization. These problems are now being of major concern of the environmentalist and to fix these problems has become an emergence. Soil microbiomes have been recognized as a potent tool for the sustainable agriculture and environment. Such microbes exhibit hidden talent to overcome the environmental related problem like pollution and soil degradation. In agriculture, soil microbiomes can be used as a biofertilizers over the chemical based products. Soil microbes help in reclamation of soil fertility, alleviation of diverse abiotic stresses, and nutrients stress that help in plant growth and development. Soil microbes help plant for growth via direct mechanisms for enhancing plant growth directly in a sustainable way like solubilization of nutrients (P, K, and Zn), fixation of nitrogen and chelation of iron as well as via indirectly by controlling pathogen growth and alleviating abiotic stress. In environment, beneficial soil microbiomes help in the degradation of environment pollutants like chemical pesticides and industrial waste by enzymatic actions and biosorption techniques. Present review deals with the diversity of soil microbiomes and their role in plant growth promotion and remediation of diverse environmental pollutants for agro-environmental sustainability.
