The continued growth in energy demand and a pressing need to lower greenhouse gas emissions have shifted the focus toward clean and sustainable energy alternatives. The purpose of this research study is to produce green hydrogen powered by renewable energy sources that reduces the dependency on fossil fuels and supports the transition to a low-carbon energy system.
The main goal of this study is to design and optimize a sustainable and cost-effective green hydrogen supply chain network using solar energy and treated wastewater. A mixed-integer linear programming model is designed to minimize the system’s total cost, which consists of installation, production, storage and transportation costs. Financial indicators like net present value, internal rate of return and payback period are evaluated for strategic and investment decision management. A genetic algorithm is used to optimize the total cost of the network by locating the optimum solution.
Numerical example reveals that the solar plant installation cost and the green hydrogen plant installation cost are the main contributors to the cost, which account for 64.71% and 32.91%, respectively. Sensitivity analysis highlights that the capital investment and the transport mode significantly influence the total cost. It is found that pipelines are 8.5% economical than compressed hydrogen trucks for long distances. A positive net present value and 18.21 % internal rate of return confirm the financial stability of the proposed supply chain.
The proposed framework provides valuable insights for policymakers, planners and industry stakeholders, helping to accelerate hydrogen and support the global framework.

The survival of plants in arid environments relies on their intricate responses to drought stress, encompassing physiological, biochemical, and molecular mechanisms. In the face of limited water availability, plants exhibit remarkable adaptations to minimize water loss and sustain vital functions. Physiologically, stomatal closure reduces transpirational water loss, while growth reduction and wilting help conserve water. Root growth alterations enable exploration of deeper soil layers for water acquisition. Biochemically, osmotic adjustment through accumulation of compatible solutes maintains cellular turgor pressure. Antioxidant production counteracts reactive oxygen species (ROS) induced by water stress. Notably, abscisic acid (ABA) accumulates, orchestrating stress responses including stomatal closure and gene regulation. Molecularly, gene expression changes underlie the activation of stress-responsive genes. Transcription factors like DREB and bZIP modulate gene expression, while ABA-dependent and ABA-independent pathways govern signaling. LEA proteins and chaperones shield cellular structures, and microRNAs fine-tune post-transcriptional regulation. This comprehensive framework underscores the remarkable capacity of plants to adapt to drought stress through an integrated network of physiological, biochemical, and molecular strategies. Understanding these responses holds promise for enhancing crop resilience and agricultural sustainability in water-scarce environments.

Xylaria papulis Lloyd, an endophytic fungus, was isolated from the stem of Andrographis paniculata Willd., commonly known as green chiretta, which is native to India and Sri Lanka. To date, no report is available on the epigenetic modulation of X. papulis using the histone methyltransferase inhibitor UNC1999. Hence, this study aims to evaluate the independent effect of this probe. The fungal culture was evaluated for antioxidant (2,2-diphenyl-1-picrylhydrazyl and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid radical scavenging assays) and antibacterial potential against six human pathogens: Staphylococcus epidermidis (ATCC 12223), methicillin-susceptible Staphylococcus aureus (MSSA) (ATCC 25923), methicillin-resistant Staphylococcus aureus (MRSA) (MU50), Enterobacter cloacae (ATCC 13047), Klebsiella pneumoniae (ATCC 700603), and E. coli (ATCC 25922). The crude extract, which was recovered from the samples treated with 250 nM of UNC1999, exhibited enhanced antioxidant and antibacterial efficacy against S. epidermidis (ATCC 12223), MSSA (ATCC 25923), MRSA (MU50), E. cloacae (ATCC 13047), and K. pneumoniae (ATCC 700603), compared to the control. The chemical profiles of crude extracts, both treated and untreated, were analyzed using gas chromatography–mass spectrometry and ultra-high-performance liquid chromatography along with high-resolution mass spectrometry). The results highlighted the capacity of UNC1999 to modulate the synthesis of cryptic metabolites in X. papulis, displaying antimicrobial and anticancer potential. This study underlines the importance of further research into the molecular mechanisms regulating these epigenetically modulated metabolic pathways.

Vegetable crops play an indispensable role in global food and nutritional security, yet their production is limited by many challenges. Biotechnology has revolutionised the improvement of vegetable crops worldwide through modern technologies such as genetic engineering, marker-assisted selection, CRISPR/Cas genome editing, tissue culture and molecular breeding, resulted in the development of climate-resilient, nutritionally enriched and highyielding cultivars that have helped to reshape the vegetable production system. Landmark achievements in plant biotechnology, namely virus-free planting material, multiple disease resistance, Bt brinjal, Flavr Savr tomato, Purple Tomato™, genome-edited GABA tomato and high anthocyanin/carotene content have revolutionised vegetable production systems globally. In addition, new intervention options such as biofortification, edible vaccines, RNA interference and biotechnology-based hybrid breeding are not only creating possibilities at the interface of agriculture and nutrition but also in public health. This status paper highlights recent advances, successful applications and emerging opportunities of biotechnology to strengthen vegetable production under changing climatic conditions.
