The activity of VvTOR (Vitis vinifera target of rapamycin) could affect sugar-related gene expression. The kinase and FATC (C-terminal of FAT (FRAP-ATM-TTRAP)) domains of VvTOR could affect sugar accumulation and sugar-related gene expression in grape (Vitis vinifera L.). Even though the kinase and FATC domains all belong to VvTOR protein, their functions were different in the regulating sugar accumulation and sugar-related gene expression. These observations will provide framework for future investigations to address other functions of TOR signalling in plant developmental and signalling pathways.

Gummosis disease is one of the main diseases that adversely affect the yield and quality of plum (Prunus spp.) fruit, an economically and nutritionally important stone fruit. Herein, the metabolite ad associated metabolic pathways alterations in Asian plum (Prunus salicina Lindl.) fruit response to gummosis disease were revealed by ultra-high-performance liquid chromatography coupled to mass-spectrometry (UHPLC-MS)-based pseudo-targeted metabolomic profiling. Elucidating plum fruit metabolomics responses to GD is essential to develop suitable strategies for therapy in the future.
FP22043Parental drought priming enhances tolerance to low temperature in wheat (Triticum aestivum) offspring
Parental drought priming induced low temperature tolerance in wheat (Triticum aestivum L.) offspring. Offspring from parental drought priming had a better redox homeostasis under low temperature. Parental drought priming promoted carbohydrate metabolism of offspring.
FP21359Response characteristics of highland barley (Hordeum vulgare) seedlings to the stress of salinity and artemisinin under freeze–thaw environment
![0000-0003-0329-8001](/media/client/orcid_16x16.png)
Freeze–thaw and NaCl stress limit plant growth. We focus on the effect of combined stress on seedlings of highland barley (Hordeum vulgare L.). Appropriate concentration of artemisinin can enhance the resistance to adverse environment.
Highland barley (Hordeum vulgare L.) is one of the important food crops for Tibetans. However, the environment in the Qinghai-Tibet Plateau is challenging for plant growth with combined stresses of saline–alkali and freeze–thaw affecting grain yield and quality. Research shows that the freeze–thaw cycle aggravate the damage of saline–alkali stress to highland barley seedlings, affecting biofilm permeability, osmotic adjustment and seedling photosynthesis. The results of this study will provide guidance and suggestions for improving crop production.
Verticillium wilt is a highly destructive fungal disease and the complex mechanism underlying plant immunity toward the causal pathogen requires thorough studies. Based on an analysis of proteome changes upon Verticillium dahliae infection in Arabidopsis thaliana L., we found formation of exosomes, enhancing tryptophan-derived compound biosynthesis and increasing abundance of some hub immunity components were essential for host defence. These new clues provide valuable information that extends the current knowledge about the molecular basis of plant immunity against V. dahliae infection.

There are few studies considering the interaction of elevated temperature and elevated CO2 on dynamic photosynthesis, particularly for C4 species. By examining dynamic photosynthesis under four different temperature and [CO2] treatments, this study showed that short-term elevated temperature and CO2 promote photosynthetic induction in the C3 plant Glycine max L. but not in the C4 plant Amaranthus tricolor L. This study suggests that greater enhancement of photosynthesis in fluctuating light for C3 plants than for C4 plants in a warming and CO2-enriched future.
