In order to investigate the effects of ammonium sulfate, an industrial by-product, on soil nutrients and microbial community when applied in different proportions instead of using urea as nitrogen fertilizer, a pot corn experiment was conducted. A completely randomized block experimental design was used, with a total of five treatments:CK (no fertilization), US (100 % urea), US (80 % urea + 20 % ammonium sulfate), US(60 % urea + 40 % ammonium sulfate), and US (100 % ammonium sulfate). The basic physical and chemical properties of soil and the dry weight of maize plants were determined by conventional methods, and microbial sequencing was performed using the Illumina NovaSeq platform.

ICAR-Indian Institute of Wheat and Barley Research, Regional Station, Shimla-2, Himachal Pradesh, India. Electronic address:

Plants face a wide array of challenges in their environment, both from living organisms (biotic stresses) and non-living factors (abiotic stresses). Among the major abiotic stressors affecting crop plants, variations in temperature, water availability, salinity, and cold pose significant threats to crop yield and the quality of produce. Plants possess remarkable adaptability and resilience, and they employ a range of genetic and epigenetic mechanisms to respond and cope with abiotic stresses.

Plant growth promoting rhizobacteria (PGPR) are also known to colonize in the soil rhizosphere and prevent the development of other soil borne pathogens residing in the root surface. These microorganisms play a vital role in growth and development of the plant and also enhances the soil fertility by enriching the soil with different beneficial nutrients. This study was aimed at isolation of different rhizobacteria and their molecular characterization in search of efficient bacterial strains with multiple growth regulating activities.

Introduction: Heat stress at terminal stage of wheat is critical and leads to huge yield losses worldwide. microRNAs (miRNAs) play significant regulatory roles in gene expression associated with abiotic and biotic stress at the post-transcriptional level.

Methods: In the present study, we carried out a comparative analysis of miRNAs and their targets in flag leaves as well as developing seeds of heat tolerant (RAJ3765) and heat susceptible (HUW510) wheat genotypes under heat stress and normal conditions using small RNA and degradome sequencing.

Article Synopsis
  • Trichoderma spp. produce secondary metabolites that help them communicate with plants and influence root development, although the specifics of how they do this are not well understood.
  • The compound anthranilic acid (2-AA), found in T. guizhouense NJAU4742, promotes the formation of lateral roots by enhancing auxin signaling and transport.
  • This study highlights 2-AA's role in lateral root development, showing that it works through mechanisms distinct from its known involvement in indole-3-acetic acid biosynthesis.

Unlabelled: Fruit ripening is an unfolding of a series of genetically-programmed modifications and tend to be highly orchestrated irrevocable phenomenon mediated by ethylene. Phytohormone ethylene also leads to over-ripening, senescence, loss of texture, microbial attack, reduced post-harvest life and other associated problems during storage and transportation of fruits. Its harmful impacts on fresh fruits, vegetables, and ornamentals result in substantial product losses even up to 80%.
