Plant growth promotion and antimicrobial activity of bud endophyte Bacillus pumilus PM2 associated with ethnomedicinal plant Spilanthes acmella (L.) L. from biodiversity hotspot of Arunachal Pradesh, India
This study aims to identify and develop a novel inoculum of highly resistant endophytic bacteria associated with Spilanthes acmella (L.) L. from the unexplored forest rich region of the Eastern Himalayan region of Arunachal Pradesh. These bacteria can adapt to the local soil conditions and offer several benefits to plants. These isolates were obtained through surface sterilization and assessed for their ability to promote plant growth and combat fungal pathogens like Sclerotium rolfsii and Sclerotinia sclerotiorum. The most effective isolate PM2 was tested using a plant inoculation assay to measure its impact on the growth of a local rice cultivar. The antimicrobial compounds produced by this isolate were identified using Thin Layer Chromatography (TLC) and Gas Chromatography-Mass Spectrometry (GC-MS). The isolate was further identified through 16S rRNA gene sequencing.
Effect of seedling age and bio-fertilizers on availability of Zinc for onion (Allium cepa L.) under different seedling age
The presented experiment was conducted at the horticulture nursery of college of agriculture, Gwalior, during the rabi seasons of 2019-20 and 2020-21 with same treatments and same site. The experiment was laid down in factorial randomized block design with two factors viz., Seedling age and bio fertilizers combinations along with 15 treatments combinations and three replications. The factor one have three levels viz., S-1 6 weeks, S2-7 weeks and S3-8 weeks whereas second factor BF1- un-inoculated (control), BF2- Azotobecter, BF3- Azotobecter+ PSB, BF4- Consortia (Azotobecter+ PSB + KMB) and BF5- Arka Microbial Consortium (Azotobecter+ PSB + ZSB). Based on pooled analysis maximum available zinc (0.55 mg kg-1) was recorded with 8 weeks old seedling and evaluation of different biofertilizers the maximum available of zinc (0.61 mg kg-1) was recorded with Arka Microbial Consortium (Azoto+ PSB + ZSB). Thus, the onion seedling of 8 weeks old transplanted with inoculation of Arka Microbial Consortium (S3 x BF5) recorded significantly higher available zinc (0.69 mg kg-1) than rest of treatment combinations.
“Screening of Garlic [Allium sativum (L.)] genotypes Growth, Yield and Quality Attributes in Malwa Region”
The mentioned experiment was conducted in rabi season of 2021-22 and 2022-23. The experiment was laid out in Randomized Block Design (RBD) with three replications. All the genotypes were randomized separately in each replication. The experiment comprised of fifteen genotypes consisting Sehore selection-1, Sehore selection-3, Amletha, Ashta-2, G-282, Malkapuri, G-189, G-384, G-323, G-2, Ichawar-5, Ashta-3, Ujjain-4, Ujjain-7, Raipura-8. During screening of different genotypes for growth parameters of the garlic genotypes, the genotype T3 (Amletha) performed very well under Malwa climate and the same trends were also reported for yield parameters at different growth stages. During the evaluation of the quality parameter like colour the various colour were recorded in different genotypes. The colour of the superior genotype Amltha is perfect white with have good market compatible.
Studies on General and Specific Combining Ability Effects in Onion (Allium cepa L.)
The present investigation was conducted to estimate General and Specific Combining Ability Effects in Onion (Allium cepa L.) among 36 genotypes of onion for foueteen characters comprised of bulb yield and its contributing characters. These genotypes were planted in Randomized Block Design with three replications during Rabi season,2022-23 at SKN College of Agriculture, Jobner. The pooled analysis of variance revealed that genotype, environment and genotype × environment interaction were significant for all the characters. The environment wise combining ability analysis revealed significant differences for GCA and SCA variances for all the characters indicating importance of both additive and non-additive gene effects in the genetic control of all the characters studied. The GCA/SCA showed preponderance of non-additive gene action for most of the characters. As regards general combining ability effects and per se performance the parents RO-1, RO-59 and Pusa Madhavi emerged as good general combiner for yield and most of the contributing characters. Out of 28 crosses studied RO-1 × RO-59, RO-1 × Pusa Shobha, RO-1 × Pusa Madhavi, Pusa Madhavi × Pusa Red, Pusa Shobha × Pusa Red and RO-1 × Pusa Red had high per se performance, SCA effects and significant heterotic effect in desirable direction for yield and most of the associated traits. The cross combinations with high SCA effects involving good × good general combiners were identified. All these crosses offer good promise for improvement of respective component characters in specific environment and ultimately bulb yield..
Effect of co-supplementation of nicotine and green-nanocolloid on the gene expression levels of buffalo oocytes during in-vitro maturation
Nicotine, a potent toxicant in cigarette smoke, adversely affects various stages of female reproductive function by acting as a pro-oxidant, increasing the generation of reactive oxygen species (ROS). Plant-derived antioxidants, known for their exceptional free radical-scavenging abilities, were the focus of this study. The primary objective was to explore the antioxidant effects of green-synthesized silver nanoparticles, termed Green nanocolloid-CcAgNps, on in vitro cultured buffalo oocytes, with the goal of mitigating nicotine’s impact. The assessment relied on the maturation rate of oocytes and the quantitative RT-PCR analysis of genes associated with antioxidant enzymes (SOD1 and GPX4), anti-apoptotic factors (BCL2) and fertility-related genes (GDF-9). Results showed a significantly higher maturation rate of oocytes cultured in a medium containing both nicotine and green nanocolloid than those exposed to nicotine alone. Moreover, GPX4 expression markedly increased in the nicotine with green nanocolloid group compared to the control group. Nicotine in the maturation medium led to a substantial upregulation of BCL2 and GDF-9 gene expression, while the addition of green nanocolloid alongside nicotine resulted in a significant downregulation of RNA expression. This indicates that the presence of green nanocolloid reduces the damage caused by nicotine and the study suggests that oocyte maturation rates improve without reliance on an enzymatic antioxidant system. This improvement is likely due to the potent free-radical scavenging capacity of silver nanoparticles capped with Cymbopogon citratus.
