“…Another assay to show the plant growth promoting effects caused by B. velezensis 83 was done with in vitro co-cultures with A. thaliana (Col-0) seedlings and comparing with those effects caused by B. velezensis FZB42 and against a control (uninoculated plants). The seeds were disinfected and sown in aseptic conditions to obtain seedlings (Barrera-Ortiz et al 2018 ). A. thaliana seedlings of 4 days after germination (DAG) were transferred to fresh agar plates with 0.2 × MS media inoculated with an aliquot of 10 µL (1 × 10 5 cfu/mL) from an overnight culture of B. velezensis 83 or B. velezensis FZB42 (Fan et al 2018 ).…”

Bacillus velezensis 83 was isolated from mango tree phyllosphere of orchards located in El Rosario, Sinaloa, México. The assessment of this strain as BCA (biological control agent), as well as PGPB (plant growth-promoting bacteria), were demonstrated through in vivo and in vitro assays. In vivo assays showed that B. velezensis 83 was able to control anthracnose (Kent mangoes) as efficiently as chemical treatment with Captan 50 PH™ or Cupravit hidro™. The inoculation of B. velezensis 83 to the roots of maize seedlings yielded an increase of 12% in height and 45% of root biomass, as compared with uninoculated seedlings. In vitro co-culture assays showed that B. velezensis 83 promoted Arabidopsis thaliana growth (root and shoot biomass) while, under the same experimental conditions, B. velezensis FZB42 (reference strain) had a suppressive effect on plant growth. In order to characterize the isolated strain, the complete genome sequence of B. velezensis 83 is reported. Its circular genome consists of 3,997,902 bp coding to 3949 predicted genes. The assembly and annotation of this genome revealed gene clusters related with plant-bacteria interaction and sporulation, as well as ten secondary metabolites biosynthetic gene clusters implicated in the biological control of phytopathogens. Despite the high genomic identity (> 98%) between B. velezensis 83 and B. velezensis FZB42, they are phenotypically different. Indeed, in vitro production of compounds such as surfactin and bacillomycin D (biocontrol activity) and γ-PGA (biofilm component) is significantly different between both strains.

“…Biochemical and genetic analyses prove that NO and H 2 O 2 undergo transient changes in their endogenous levels which are finely tuned to various developmental, and environmental changes associated with root growth (Castillo et al, 2015 ; Kushwaha et al, 2019 ; Mukherjee & Corpas, 2020 ; D. Piacentini, Della Rovere, et al, 2020 ; Piacentini et al, 2021 ; Raya‐González et al, 2019 ; Sanz et al, 2015 ; Sun et al, 2018 ; Szepesi et al, 2022 ; Wei et al, 2018 ). Among the various signalling molecules associated with NO, auxin, ethylene, and brassinosteroids are known to be involved in NO‐associated ROS signalling pathways during root growth and development (Barrera‐Ortiz et al, 2018 ; Y. Fu, et al, 2019 ; Jacobsen et al, 2021 ; Liu et al, 2017 , 2022 ; Raya‐González et al, 2019 ). The interaction of NO and auxin during root development involves the coordination of redox homoeostasis and the modulation of various redox regulatory proteins.…”

Hydrogen peroxide (H2O2) is a reactive oxygen species (ROS) and a key modulator of the development and architecture of the root system under physiological and adverse environmental conditions. Nitric oxide (NO) and hydrogen sulphide (H2S) also exert myriad functions on plant development and signalling. Accumulating pieces of evidence show that depending upon the dose and mode of applications, NO and H2S can have synergistic or antagonistic actions in mediating H2O2 signalling during root development. Thus, H2O2‐NO‐H2S crosstalk might essentially impart tolerance to elude oxidative stress in roots. Growth and proliferation of root apex involve crucial orchestration of NO and H2S‐mediated ROS signalling which also comprise other components including mitogen‐activated protein kinase, cyclins, cyclin‐dependent kinases, respiratory burst oxidase homolog (RBOH), and Ca2+ flux. This assessment provides a comprehensive update on the cooperative roles of NO and H2S in modulating H2O2 homoeostasis during root development, abiotic stress tolerance, and root‐microbe interaction. Furthermore, it also analyses the scopes of some fascinating future investigations associated with strigolactone and karrikins concerning H2O2‐NO‐H2S crosstalk in plant roots.

“…NO-mediated stimulation of jasmonatedependent basal defense response conferred resistance to tomato plants against root-knot nematode (RKN) by increasing the expression of Protease Inhibitor 2 (Zhou et al, 2015). Studies have also shown that enhanced endogenous levels of NO causes downregulation of JAZ repressor proteins JAZ1 and JAZ10 in the meristematic root regions, thereby improving root architecture and stomatal apparatus in transgenic Arabidopsis thaliana (Barrera-Ortiz et al, 2018;Yastreb et al, 2018). Recently, a study conducted by Avila et al (2019) confirmed the synergistic role of NO/JA in stimulating defense response in Solanum quitoense plants against F. oxysporum, thereby suggesting the activation of the corresponding signaling pathway by both defense priming compounds.…”

Salicylic Acid and Nitric Oxide: Insight Into the Transcriptional Regulation of Their Metabolism and Regulatory Functions in Plants

et al. 2021

Salicylic acid (SA) and nitric oxide (NO) are key signaling molecules required to activate the plant's innate immunity against abiotic stresses and biotrophic attackers. Stress-induced signaling and accumulation of SA and NO triggers extensive transcriptional reprogramming of defense-related genes, induced biosynthesis of secondary metabolites and anti-microbial compounds, thereby protecting/steering plant growth and immunity. Transcriptional regulation of SA and NO signaling are crucial for fine-tuning important cellular and metabolic functions, thus making plant defense impervious against many pathogens. The development of an impenetrable immune response is often associated with an unavoidable trade-off in the form of active suppression of plant growth and reproduction. Therefore, we highlighted recent advancements and research to unravel transcriptional regulation of SA and NO signaling essential for fulfilling their role as defense signaling molecules. We also emphasized comprehensive knowledge related to transcriptional reprogramming of SA and NO signaling important in strengthening plant growth-immunity trade-off. We also highlighted the progress on SA and NO signaling playing an indispensable role in stimulating plant-microbe interaction to modulate crucial plant functions.
