    Exploring the Adverse Impact of Pesticides in Honey Bees and Their Virulence
    (AMG Transcend Association, 2024) Kumari P.; Lohar S.; Godara V.; Prajapati M.K.; Nagar V.; Singhal A.; Mavry B.; Pandit P.P.; Sharma A.; Rai A.R.; Krishna R.; Sankhla M.S.
    Honey bees (Apis mellifera L.) significantly enhance seed production, fruit set, and yield through pollination. However, the world is facing a major challenge of honey bee loss due to the excessive use of pesticides facilitated by technological advancements. Pesticides are harmful to pollinators and can cause lethal and sublethal effects through dermal contact, ingestion, or inhalation of contaminated air. Pesticide exposure in agricultural fields has led to honey bee toxicity, which affects their neurophysiological and immune systems and, consequently, their life cycle. This toxicity also leads to contamination of bee products, which can negatively impact human health, affecting the nervous and digestive systems, among others. While there is limited knowledge about the impact of pesticides on wild honey bees, it is crucial to understand this to guide agricultural practices and legislation aimed at safeguarding these important pollinators. It is, therefore, essential to take major steps to control pesticide toxicity in honey bees and prevent further harm. � 2024, AMG Transcend Association. All rights reserved.

    Harnessing the nutraceutical and therapeutic potential of Allium spp.: current insights and future directions
    (Frontiers Media SA, 2024) Gorrepati K.; Krishna R.; Singh S.; Shirsat D.V.; Soumia P.S.; Mahajan V.
    Apart from the culinary usage, Alliums are known for their therapeutic potential since antiquity. Alliums contain diverse bioactive compounds such as, sulfur-containing compounds (allicin, diallyl sulfides), flavonoids, and saponins. These compounds have demonstrated a wide range of pharmacological actions, including antioxidant, anticancer, anti-inflammatory, antimicrobial, neuroprotective, cardioprotective activities and treatment of metabolic disorders such as diabetes and hyperlipidemia. Despite encouraging preclinical results, translating these findings into clinical practice remains difficult, necessitating more rigorous human trials and molecular research. One of the major constrain in enhancing the therapeutic efficacy of these bioactive compound is to develop large-scale extraction techniques besides improving their stability, solubility, and bioavailability. The current scenario urges to focus research on optimizing the bioavailability of these compounds, evaluate their synergistic effects with existing therapies, as well as their long-term safety. This perspective article provides a comprehensive overview of the therapeutic potential of Allium spp. and suggests the key avenues for future research aiming at realising their full clinical potential.

    Impact of Plant Growth-Promoting Microorganism (PGPM) Consortium on Biochemical Properties and Yields of Tomato Under Drought Stress
    (Multidisciplinary Digital Publishing Institute (MDPI), 2024) Krishna R.; Ansari W.A.; Altaf M.; Jaiswal D.K.; Pandey S.; Singh A.K.; Kumar S.; Verma J.P.
    Drought is the most important abiotic stress that restricts the genetically predetermined yield potential of the crops. In the present study, four tomato varieties: Kashi Vishesh, Kashi Aman, Kashi Abhiman, and Kashi Amrit, were used to study the effect of PGPMs (plant growth-promoting microorganisms). PGPM strains, Bacillus megaterium BHUPSB14, Pseudomonas fluorescens BHUPSB06, Pseudomonas aeruginosa BHUPSB01, Pseudomonas putida BHUPSB0, Paenibacillus polymixa BHUPSB17, and Trichoderma horzianum, were used as the consortium. The control group was irrigated up to 80% of field capacity, while 7-, 14-, and 21-day water-deficit-exposed (DWD) plants� pot soil moisture was maintained to 40, 25, and 15% of the field capacity, both with and without the PGPM inoculation condition. The physiological parameters, such as electrolyte leakage, relative water content, photosynthetic efficiency, and chlorophyll color index, were significantly improved by PGPM application under progressive drought stress, compared to the control. PGPM application enhanced the proline accumulation and reduced the formation of hydrogen peroxide and lipid peroxidation under drought stress. The plant growth attributes were significantly increased by PGPM application. The Kashi Amrit variety showed the highest fruit yield among the four varieties under all the treatments. The PGPM consortium application also improved the soil physico-biological properties and nutrient availability in the soil. The PGPM consortium used in this study can potentially mitigate drought stress on tomato in drought-prone regions and act as a biofertilizer. The present study will open a new avenue of drought stress management in tomato. � 2024 by the authors.
