Species | Omic approach | Findings | References |
|---|---|---|---|
Avicennia officinalis L | RNA-seq and de novo assembly and annotation | 22, 254 transcripts and 613 microsatellite markers. They identified different copies and isoforms of three candidate genes, AoPIP, AoTIP, and AoDHN1, which might be involved in salt excretion via salt glands | Lyu et al. 2018 |
Camellia sinensis (L.) Kuntze | RNA-seq/DEG | 3715 differentially salt stress expressed genes were identified | |
Picea wilsonii Mast | RNA-seq/DEG | 3438 (1592 up-regulated and 1706 down-regulated) differentially expressed genes were identified under salt treatments. qRT-PCR analyses showed that the expression of PwNAC genes were induced by salt treatment, suggesting that these genes are involved in salt stress resistance | Guo et al. 2020 |
Populus alba × Populus glandulosa and Populus simonii × Populus nigra | RNA-seq/DEG | A total of 276 up-regulated DEGs and 159 down-regulated DEGs were identified to be shared in the four species. Overexpression of a transcription factor (NAC57) gene conferred salt tolerance in transgenic Arabidopsis | Yao et al. 2018 |
Populus pruinosa, Populus euphratica, Populus trichocarpa, and Populus tomentosa | RNA-seq/DEG | On the basis of the 7822 1:1 orthologs between the four poplar species, a total of 1335 differentially expressed genes were identified | Luo et al. 2017 |
Populus tomentosa Carrière | RNAseq/DEG | 3991, 4603, and 4903 genes were up-regulated, and 1408, 2206, and 3461 genes were down-regulated at 6, 12, and 24 h under salt treatments, mainly identified with ROS and hormone regulatory networks | Zheng et al. 2015 |
Prosopis juliflora (Sw) DC | De novo assembly of transcriptome/DEG | 666 genes were responsive to salt stress in leaf tissue, of which 110 were responsive to drought stress too, and 20 were responsive to salt stress in root tissue also. Similarly, 1044 were responsive to salt stress in root tissue, of which 832 were responsive to drought stress too, and 20 were responsive to salt stress in leaf tissue also. More transcriptome changes in root tissue compared to leaf under the stress, drought stress caused more differential gene expression than salt stress | George et al. 2017 |
Vitis vinifera L | RNA-seq/DEG | 2472 differentially expressed genes in salt-responsive grapevine leaves were identified | Guan et al. 2018 |
Vitis vinifera (Thompson seedless variety) | RNA-seq/DEG | 714 differentially expressed genes were identified under 150Â mM salinity stress, where 311 genes were down-regulated and 406 genes were up-regulated. 20 salt stress-induced DEGs were selected for validation through qRT-PCR analysis; these genes were involved in pathways related to salt tolerance (signaling transduction, transcription factor, defense metabolism, antioxidant genes, cell wall, and growth) | Das and Majumder 2019 |
