Summary: Plant cell culture can be manipulated using plant growth regulators to induce metabolic changes for the production of specialized metabolites. This study investigated different combination ratios of PGRs to induce metabolic changes in Bidens pilosa callus, revealing distinct metabolomic profiles dominated by chlorogenic acids. While organogenesis was not achieved, the results demonstrate the potential of using exogenous PGRs to manipulate plant metabolism for in vitro production of specialized metabolites.

Summary: The metabolic, hormonal, enzymatic, and non-enzymatic responses of various plant components to plant growth regulators under heat stress were examined in rice cultivars. Heat stress altered antioxidant activities and hormonal balance, reduced soluble sugars, proteins, and proline, and increased H2O2 and MDA content. Huanghuazhan showed higher activities of antioxidant enzymes and higher ABA levels compared to IR-64.

Summary: There is a growing interest in using beneficial microorganisms as alternatives to chemical or plant-derived molecules for producing therapeutic agents. Bacterial endophytes, which are plant-associated microorganisms, can synthesize a wide range of secondary metabolites with unique chemical structures that have anti-microbial, antiviral, anti-cancer, and anti-inflammatory properties. The production of these bioactive compounds can also benefit the host plant.

Summary: Artemisia annua is the sole plant source of artemisinin, the key component of first-line antimalarial drug, but its content is low. Research on endophytic microbes in the plant aims to understand their regulatory roles in A. annua growth and artemisinin production. Endophytes promote plant growth by enhancing photosynthesis, nutrient absorption, and phytohormones, while also participating in plant defense against microbial pathogens.

Summary: Biotic stresses pose a threat to global food security and crop yield worldwide. Plants respond to these stresses by triggering various adaptive changes, including the synthesis and accumulation of plant secondary metabolites. Transcription factors and miRNAs play crucial roles in regulating the production of these metabolites during stress conditions. This review summarizes the role of stress-inducible TFs in synthesizing and accumulating secondary metabolites and highlights how miRNAs fine-tune the expression of stress-responsive transcription factors during biotic stress.

Summary: Secondary metabolites are important specialized molecules with proven health-promoting effects on humans. Exogenous jasmonates (JAs) have been recognized for their ability to trigger plant growth and development and can also effectively elicit the synthesis of secondary metabolites. However, large-scale production of these metabolites is limited, but advancements in plant cell culture technology and synthetic biology offer potential avenues for overcoming this limitation.

Summary: This study evaluated the response of different plant growth regulators on callus induction and regeneration in three sugarcane genotypes. The best callus response was obtained with the combination of 2,4-D and Kinetin, while Kinetin and BAP were found to be the most effective for shoot induction, and NAA and IBA were used for root induction. The results provide valuable information for optimizing tissue culture protocols for sugarcane.

Summary: Chicory is a widely distributed perennial herb that is commonly used for extracting inulin. This study investigated the effects of plant growth regulators and light conditions on the growth and inulin accumulation of chicory callus. The results showed that specific combinations of PGRs and light conditions led to steady increases in callus fresh weight and inulin content. This finding can meet the increasing demand for organic inulin sources in production practice.

Summary: This study examined the activity patterns and movement characteristics of 19 Asiatic lions through satellite radio-collars with activity sensors. The results showed that the lions' movement and activity varied based on age, sex, and social status. The study also found that land tenure characteristics influenced the lions' home range and daily distance moved. It is important to consider these variations in movement behavior and demographic factors in conservation planning.

Summary: Comparative studies on the diet of large felids in protected areas and surrounding multi-use landscapes are important for their conservation. Based on scat analyses, the dietary composition of Asiatic lions in Gir PA and the surrounding multi-use land matrix was assessed. The results showed that Asiatic lions in the Gir PA primarily consumed wild prey, while in the multi-use land matrix, they consumed both wild prey and domestic livestock. The study highlights the importance of considering different habitat types and prey availability for effective lion conservation management.
