Abstract Background Larch (Larix gmelinii (Rupr.) Kuzen.) is an important timber and ecological tree species in northern China. Excellent germplasm resources have been acquired through time-consuming traditional breeding. Molecular breeding offers a promising approach to shorten the cycle achieve genetic improvements more efficiently. MicroRNAs (miRNAs) are non-coding, single-stranded small RNAs that primarily affect plant growth stress resistance, including drought stress. However, study of miRNAs larch under has not well explored. Results In this study, investigate function Lol-miR11467 PEG osmotic larch, embryogenic callus tissue Larix kaempferi 3 × L. 9 was employed as experimental material, serving explants for study. Lol-miR11467was transferred into using Agrobacterium-mediated method determine physiological changes survey gene expression overexpressing cell lines. The results showed fresh weight, peroxidase (POD), soluble protein sugar content were lower than wild-type, while malondialdehyde (MDA) increased osmoticstress. Transcriptome analysis genes associated with phenylpropanoid metabolism, transcription factors, oxidoreductase, hormone signal transduction, glucose metabolism bioprotective macromolecules mainly downregulated Conclusions Overall, these indicated resistance lines reduced. This study'sfindings might provide foundation understanding molecular mechanisms potentially contributing development strategies improving resilience environmental stresses.

Hunger (811 million people, 2020) and food waste (931 tonnes annually, are long-standing interconnected challenges that have plagued humankind for centuries. Food originates from various sources, including consumption habits failures within the supply chain. Given growing concerns regarding insecurity, malnutrition, hunger, there is a pressing need to recover repurpose as much possible. A body of knowledge identifies valorisation (including upcycling) one strategies fight hunger by positively impacting availability security. This paper evaluates potential role valorisation, upcycling, in reducing global hunger. literature search was conducted examine how converting into value-added products, such formulations farming inputs, can contribute increasing availability. The benefits waste-to-food operations improving through producing ingredients products materials would been wasted or discarded otherwise were discussed.
