Background: Trehalose is a nonreducing disaccharide containing two glucose molecules linked through an α,α-1,1-glycosidic bond. This unique chemical structure causes trehalose levels to fluctuate significantly in plants under stress, where it functions as an osmoprotectant, enhancing plant resistance to stress. Previous studies have confirmed that the trehalose synthesis pathway is widely conserved across most plants.

- The study investigates how trehalose metabolism affects the cold acclimatization in kiwiberry, focusing on a specific gene (TPP) that helps plants survive low temperatures.
- Transcriptome analysis revealed that this gene is more active in lateral buds, roots, and stem cambia during autumn when temperatures drop.
- Overexpressing the TPP gene in kiwiberry led to significant increases in trehalose levels and enhanced freezing tolerance, along with improved ability to manage stress factors like reactive oxygen species.
Pyrite bio-leachate, mine wastewater can sterilize the rice (Oryza sativa L.) seeds and promote the germination.

We developed the way to use pyrite bio-leachate (PBL), the wastewater of bioleaching of refractory gold ore in agriculture. PBL contains high amount of iron and at certain concentration, iron has toxicity on microorganisms. Therefore PBL can be used for rice seed sterilization.
