The purpose of the study is to investigate the function of TRPV4 on ferroptosis in ALI mice induced by lipopolysaccharide (LPS). In vitro, the regulation of TRPV4 on Ca2+ and ferroptosis was detected by CCK-8, fluorescent probe, and western blot in BEAS-2B cells. In vivo, the role of TRPV4 antagonists on ALI mice was analyzed by determination of pulmonary inflammation, pulmonary edema, and ferroptosis.

The present experiment with different isolates of Azotobacter sp. was carried out to find out effective isolate for plant growth promoting activities and biological control. In case of in vitro screening for plant growth promoting efficacy, it was found that chilli seeds bacterized with AZT8 exhibited the highest per cent seed germination (98%) which was followed by AZT6 (86 %) and AZT4 (81%).

Cowpea is an important leguminous vegetable crop usually grown during Pre-kharif, Kharif and Rabi season under West Bengal condition. Now days this crop is severely affected due to biotic stress. Seven foliar pathogens namely Alternaria alternata, Colletotrichum capsici, Corynespora cassicola, Rhizoctonia solani, Fusarium ciceri, Sclerotium rolfsii and Curvularia lunata were isolated from the diseased cowpea crop in Jaguli Instructional farm of BCKV.

Replant disease is a major problem of apple orchards, which is a main cash crop in TransHimalayan region. The cause of this replant problem includes both biotic and abiotic factors, such as low nutrients, phytotoxins, actinomycetes, fungal complexes and nematodes. Fungi and oomycetes belonging to the well-known root rot complex are important factor of replant problems in apple.

Antagonistic potentiality of four isolates of Trichoderma species viz. Trichoderma viride isolate A, Trichoderma viride isolate M, Trichoderma harzianum isolate C and Trichoderma harzianum isolate L against Beauveria bassiana causing white muscardine disease of Silk worm, Bombyx mori L, was studied invitro by studying the mycelial interaction between them as well as by the effect of culture filtrate of biocontrol agents on sporulation and spore germination of pathogen.

Fungal phytopathogens are causes of many plant disease and maximum loss of crop yields, especially in tropical regions. Chemical fungicides are extensively used in agriculture. However, these products may cause problems such as environmental pollution and affect human health, microorganism particularly fungi as biocontrol agents have high potential to control plant disease and ecofriendly without side effect on the environments.

Effect of eight antagonists viz., Trichoderma atroviride, T. harzianum, T. virens, T. fasciculatum, T. asperellum, T. viride, Pseudomonas fluorescens and Bacillus subtilis were studied for their antagonism against Macrophomina phaseolina by dual culture method and six fungicides viz. Azoxystrobin 23 SC, Carbendazim (12%) + Mancozeb (63%) 75 WP, Carbendazim (25%) + Mancozeb (50%) 75 WS were evaluated at two different concentrations (500 ppm and 1000 ppm) by poisoned food technique against the same pathogen.

In the present study in-vitro antagonistic effect of four species of Trichoderma. T. harzianum (FCBP-732), T.viridi (FCBP-1123), T. koningii (FCBP-951), T. aureoviridie (FCBP-691) was studied (assessed) against a destructive soil-borne plant pathogen Sclerotium rolfsii Trichoderma species were screened by dual culture method.

The aim of the study was to access the anti-bacterial and anti-fungal activity on the growth of Alternaria porri under in vitro condition. The antagonistic activity of bacterial and fungal antagonists (Pseudomonas and Trichoderma spp.) was determined by the dual culture technique both on King’s B and PDA media respectively, Paper disc assay and Agar well mathod. Plates were incubated at 28ºC for 7 days and 2 days. The antagonistic activity of these antagonists was evaluated by mycelial growth and mycelial dry weight of test fungus (Alternaria porri).

Efficacy of three potential microbial bioagents, viz. Trichoderma viride, Bacillus thuringiensis, Pseudomonas fluorescens were evaluated against bacterial wilt of lettuce under hydroponic culture system. The microbial bioagents were tested in vitro for their antagonistic properties against Ralstonia solanacearum, the causal agent of bacterial disease in lettuce. Bioagents applied alone or as consortia, significantly reduced bacterial wilt pathogen in vitro producing varying sizes of inhibition zones in TTC medium.

Eight native strains of Pseudomonas spp. were isolated from rhizosphere of various sugarcane clones on Pseudomonas agar using standard protocols. These strains were characterized for antagonistic traits on red rot pathogen in vitro and Plant growthpromoting (PGP) activities in greenhouse up to 30 days from single node setts in portrays as sett treatment (@109 CFU ml-1 ). The promising isolate was characterized up to species level by PCR amplification of 16S rDNA region using Pseudomonas specific primers. Elite strain was identified as P. putida strain AKP-1.

Lentil (Lens culinaris Medik) is an important crop, the major states producing lentil are Madhya Pradesh, Uttar Pradesh, Bihar and Punjab. Lentil is an important component of farming systems in our country. It is one of the important and most nutritious rabi pulses. Vascular wilt causing by Fusarium oxysporum f.sp. lentis, Sclerotium rolfsii Sacc. causing collar rot and Sclerotinia sclerotiorum (Lib.) de Bary) causing stem rot, is most destructive soil borne diseases of lentil growing area worldwide. Use of chemicals continues to be major strategy to mitigate the menace of crop disease.

Plant Growth Promoting Rhizobacteria (PGPR) are a group of rhizospheric bacteria, found in association with plant roots and enhance the growth of plant directly or indirectly. To isolate multi-trait PGPR, total 7 soil sample were collected from sugarcane rhizosphere with diverse previous cropping pattern. Total 38 distinct isolates were obtained in pure culture from above collected samples, were screened for their ability of plant growth promoting characters in in vitro conditions. Out of this, 100% showed antagonistic potential, 55.26%, 42.11% and 52.

This work was aimed at isolating AHL degrading bacteria from fish culture pond soil, with abilities appropriate for use as probiotic in aquaculture. The presence of an autoinducer inactivation (aiiA) homologue gene and AHL-inactivation assay showed that BacillusthuringiensisQQ17, which was one among the 20 isolates, could rapidly degrade synthetic C6-HSL in vitro and hampered violacein production by Chromobacterium violaceum.

Piper longum Linn. (Piperaceae) is a valuable medicinal herb and due to its high therapeutic composition, there is a need to protect the plant from severe diseases as they may hinder the medicinal properties. In this paper we report the Anthracnose disease of P. longum caused by Colletotrichum boninense for the first time. The morphological characteristics of the pathogen have been described and its identity was confirmed by molecular characterization. Also Trichoderma virens was subjected to antagonistic test against C. boninense in vitro and the results showed 64.28% inhibition by T.
