Appointment on Visitation important
Topic: Plant Physiology And Phytochemistry
Description:
My research interests are broadly focused on enhancing plant (medicinal and crop) growth using microbial and non-microbial biostimulants under stressful conditions.
I am equally interested in plant secondary metabolism, viz., the pharmacological properties of plants and their microbial symbionts, endophytes.

Serratia marcescens., AN ENDOPHYTIC BACTERIA OF Ficus microcarpa L. WITH PLANT GROWTH-PROMOTING POTENTIAL
Endophytic microbes are non-pathogenic
microorganisms that colonise the internal parts of plants, helping to enhance
plants’ growth. They are relatively untapped resources with large potential
applications for crop production. They promote plant growth and enhance their
resistance to environmental stressors by producing organic acids,
phytohormones, siderophores, hydrogen cyanide and ammonia for their host plants.
However, the endophytic community of plants is influenced by multiple factors, including
host genetics, environmental conditions, and other microbes. Thus, it is
important to characterise well-adapted endophytes from indigenous species. This
study aimed to isolate, characterise, and investigate the plant
growth-promoting potential of bacterial endophytes from microcarpa.
Healthy, disease-free leaves were collected, surface-sterilised, and then
incubated on nutrient agar for 5 days. Two distinct endophytic bacterial
isolates, designated Ficus bacteria isolate 1 (FB1) and Ficus bacteria isolate
2 (FB2), were obtained and evaluated for their plant growth-promoting traits,
including ammonia production, hydrogen cyanide production, and phosphate
solubilisation. FB1 demonstrated higher ammonia production and phosphate solubilising
ability, while FB2 showed more pronounced hydrogen cyanide activity. One of
these strains FB1, with the most promising plant growth-promoting properties,
was identified as Serratia marcescens (CP026050.1). Based on the 16S rRNA
sequence result, S. marcescens shared high homology (96.79%) with other
related species. The findings
highlight S. marcescens as a potential plant growth-promoting bacterium,
suggesting its use as a biostimulant to improve agricultural productivity.
Further studies are recommended to validate its plant growth-promoting properties
in diverse plant systems.
