Recently, biorefinery systems have been explored and developed for the holistic valorization of fruit and vegetable waste. The current research aims to summarize recent studies examining the valorization of different fruit and vegetable by-products using a holistic biorefinery approach. The various steps in a biorefinery process are presented and discussed.

In the current study, different biorefinery systems are proposed based on fruit and vegetable waste composition. In conclusion, the phytochemicals and products produced during the biorefinery process can benefit various industries, such as: the food, pharmaceutical, cosmetics, transportation, chemical, heating, agricultural, and horticultural industries.

The first innate immune response is activated by detecting microbe/pathogen-associated molecular patterns (MAMPs/PAMPs) and is called PAMPs-triggered immunity (PTI). The second immune response is triggered by recognizing pathogens' effector proteins named effectors-triggered immunity (ETI). Calcium-dependent protein kinases (CDPKs or CPKs) are well-known calcium sensors that have a mediator role both in PTI and ETI. Calcium can bind to the elongation factor (EF)-hand domain at the C-terminus of CDPKs, which then phosphorylates substrates at the N-terminal catalytic kinase domain to transfer calcium signals directly. Improving the stress resilience of crops is a critical strategy in attaining global food security. In plants, when a stimulus is seen, there is an increase in Ca<sup>2+</sup> concentration, which activates CDPKs which are in charge of sending out the immunological signals needed for disease tolerance. During the immune response, CDPKs are subject to numerous levels of regulation, including Ca<sup>2+</sup> dependency to decipher various Ca<sup>2+</sup> signals. Furthermore, salicylic acid (SA) regulation by CDPKs provides a comprehensive overview of CDPKs-mediated SA signaling during immune response in plants under pathogen attack. The critical part of CDPKs in SA biosynthesis, from the regulation of SA biosynthesis to how NPR1 perceives SA upon biotic stress, is comprehensively reviewed in this paper with the latest advancements in research.

We emphasize the urgent need for the development of such a next-generation drug delivery system and discuss the opportunities/hurdles as well as the questions that remain to be addressed.
