Abstract
Mongolian willow (Salix linearistipularis) is a naturally occurring woody dioecious plant in the saline soils of north-eastern China, which has a high tolerance to alkaline salts. Although transcriptomics studies have identified a large number of salinity-responsive genes, the mechanism of salt tolerance in Mongolian willow is not clear. Here, we found that in response to Na2CO3 stress, Mongolian willow regulates osmotic homeostasis by accumulating proline and soluble sugars and scavenges reactive oxygen species (ROS) by antioxidant enzymes and non-enzymatic antioxidants. Our quantitative proteomics study identified 154 salt-sensitive proteins mainly involved in maintaining the stability of the photosynthetic system and ROS homeostasis to cope with Na2CO3 stress. Among them, Na2CO3-induced rubredoxin (RUB) was predicted to be associated with 122 proteins for the modulation of these processes. The chloroplast-localized S. linearistipularis rubredoxin (SlRUB) was highly expressed in leaves and was significantly induced under Na2CO3 stress. Phenotypic analysis of overexpression, mutation and complementation materials of RUB in Arabidopsis suggests that SlRUB is critical for the regulation of photosynthesis, ROS scavenging and other metabolisms in the seedlings of Mongolian willow to cope with Na2CO3 stress. This provides more clues to better understand the alkali-responsive mechanism and RUB functions in the woody Mongolian willow.

Abstract
Salix kochiana Trautvetter 1837 is one of the highest value shrubs present in northern China with important economic and ecological benefits. This study revealed the structural characteristics and phylogenetic relationships of chloroplast genes in S. kochiana Trautv. The results showed that the length of the complete chloroplast genome was 155,657 bp, which was a typical circular double-stranded structure, including an 84,458 bp large single-copy region (LSC), a 16,221 bp small single-copy region (SSC) and a 27,489 bp pair of inverted repeat regions (IRA and IRB). The chloroplast genome contains 48,757 A bases, 28,017 G bases, 49,843 T bases, and 29,040 C bases, with a GC content of 36.66%. Through bioinformatics annotation, a total of 126 genes were found in the chloroplast genome, including 81 protein-coding genes, 37 tRNA genes, and eight rRNA genes. Phylogenetic analysis showed that S. kochiana Trautv. was closely related to S. triandroides.
