“…Similarly, Maheshwari et al (2019) reported that seed treatment with B. subtilis strain (CPHR3) was the most effective in promoting chickpea growth in pots under screen house conditions. Datta and Lal (2012) also correlated Fusarium wilt resistance with phenol content in chickpea varieties and observed maximum phenol content (21.8 mg gdw −1 ) in wilt-resistant cultivars and minimum (16.5 mg gdw −1 ) in susceptible lines of chickpea.…”

Background Chickpea is the most important legume crop in India, and its productivity is significantly lowered due to biotic constraints such as wilt caused by Fusarium oxysporum f. sp. ciceris. Endophytes help plants to thrive better under stress conditions by regulating plant hormones and inducing systemic resistance. The aim of the present study was to identify chickpea root bacterial endophytes having antagonistic ability for the management of the Fusarium wilt. Results Twenty endophytic bacterial strains were isolated from the susceptible and resistant chickpea cultivar, amongst which 35% bacterial endophytes gave positive results for siderophore and 15% isolates were HCN producers, whereas 55% showed good growth on ACC-supplemented medium. Based upon 16S rRNA phylogenetic analysis, efficient endophytic bacterial isolates CRBE1, CRBE3 and CRBE7 were identified as Priestia megaterium, Brucella haematophila and Microbacterium paraoxydans, respectively. Bacterial endophyte CRBE7 and CRBE3 showed pronounced antagonistic activity against Fusarium oxysporum f. sp. ciceris under in vitro conditions. Inoculation of chickpea with isolated bacterial endophytes alone and in combination through seed priming resulted in significant biocontrol activity against Fusarium wilt of chickpea under screenhouse conditions. Biopriming of chickpea seeds alone with CRBE3 and as consortium of CRBE3 + CRBE7 upsurged the phenol content in susceptible and resistant chickpea varieties JG 62 and HC 3, which indicated the role of promising endophytes as potential bio-agents under in vivo conditions. Conclusions Chickpea root bacterial endophytes Priestia megaterium (CRBE1), Brucella haematophila (CRBE3) and Microbacterium paraoxydans (CRBE7) exhibiting antagonistic activity could be incorporated in integrated disease management module against Fusarium wilt of chickpea.

“…These chemical ingredients exhibit varied endogenous functions, specifically primary metabolites are directly involved in the growth and development of plants whereas secondary metabolites are known to protect plants from various abiotic and biotic stresses 4 . Various groups of secondary metabolites including phenolic compounds, flavanoids, steroids, triterpenoids, alkaloids, isoflavanoquinones, anthocyanins, toxalbumin are known 5,6 .…”

Plant metabolites with therapeutic values provide enormous scope for novel drug leads. In this context several traditional medicinal plants are targeted for phytochemicals identification and characterization worldwide. The current investigation was undertaken to identify metabolites present in seeds of Abrus precatorius (L.), a medicinal plant with potent anti-inflammatory, antimicrobial, antioxidant, antifertility, and antispermatogenic activity. Ethanol extracted seed metabolites were identified by LC-ESI-Q-TOF-MS system equipped with a G4220B pump, G4226A auto sampler and G1316C, and a diode array detector. Metabolites profiling yielded large sets of data were analyzed by METLIN Mass Spectral Database. Metabolomics analysis revealed presence of Desethyletomidate, Butabarbital, 4-aminohippurate, 20α-Dihydroprogesterone glucuronide, Phenethylamine, Etomidate, Oxyquinoline, Norfloxacin, Phenylethylmalonamide (PEMA), and Dihydro streptomycin with typical plants metabolites. The masses of these uncommon metabolites were 216.08, 212.11, 222.09, 492.27, 121.09, 244.12, 145.05, 319.12, 206.10 and 567.28 respectively. These metabolites contribute to various drug preparations used to treat human ailments.
