Phosphoenolpyruvate (PEP) plays a key role in the development of plants and exists in a wide variety of species. Research on the metabolic activities of PEP in plants has received increasing attention. PEP regulates multiple processes in plant growth and development. This article provides a comprehensive summary of these pathways, including embryo formation, root development, synthesis of secondary metabolites, and the formation of lignification. We also summarize new findings, including PEP's role in nodule energy sensing and carbon allocation under the influence of ozone. This review displays the complex and differential regulatory pathways in plant growth and development and provides a reference for basic and applied research on PEP metabolism in plants.

The aim of the study was to reduce the chemical fertilizers with microbial inoculant-rich vermicompost, which enhanced the growth, flowering, and soil health of the tuberose crop. A total of six treatments were applied with reducing doses of synthetic fertilizers under a factorial randomized design and replicated thrice. In this study, vermicompost (VC) made from cow dung and vegetable waste utilizing Eisenia foetida and their mixed biomass were enriched with microbial inoculants and assessed for their impact on microbial and enzymatic populations including urease, acid phosphatase activity and dehydrogenase activity in soil, nutrient availability, and tuberose development and flowering.

This study evaluated how dietary black seed oil (Nigella sativa L.) against the diazinon waterborne toxicity on Nile tilapia (Oreochromis niloticus), focusing on growth performance, hematological and biochemical parameters as well as oxidative stress markers and histological changes. A 40-day feeding trial was carried out using four experimental groups: Group 1 (control group), Group 2 (N.

Due to the growing environmental and health concerns with chemical plant stimulants, there is a growing need to find alternative sources of plant stimulants that could help the seeds germinate and sustain their growth in the global climate change scenario. The article compares various seed stimulants such as chemical compounds (benzothiadiazole, salicylic acid, glycine betaine), alcoholic extracts from commercial plant products (English oak bark, ginger spices, turmeric spices, caraway fruits) and from wild plant leaves (Japanese pagoda tree, Himalayan balsam, stinging nettle and Bohemian knotweed) and their effects on wheat seed germination and seedling characteristics. It was found that BTH had significantly lower effect on seedling characteristics such as SG3 (%), SG5 (%), R/S III, SVI I (mm) and SVI III (mg) followed by ZO on SG3 (%), SG5 (%) and GI (unit).

Somatic embryogenesis (SE) is an in vitro mass propagation system widely employed in plant breeding programs. However, its efficiency in many forest species remains limited due to their recalcitrance. SE relies on the induction of somatic cell reprogramming into embryogenic pathways, a process influenced by transcriptomic changes regulated, among other factors, by epigenetic modifications such as DNA methylation, histone methylation, and histone acetylation.
