Transcriptome Analysis of Dragon Fruit in Response to Salt and Drought Stresses
Salinity and drought stresses are frequent threats to plants throughout their lives,and the two frequently coexist,wreaking havoc on plant growth and development.According to physiological research,salinity and drought stresses cause changes in osmotic pressure,resulting in membrane damage and other effects.Similar phenotypic and physiological changes occur under salinity and drought stresses.However,few research have examined the differ-ences or similarities between salinity and drought-induced gene expression regulation.This study uses PEG-6000 and NaCl to treat seven days dragon fruit(Hylocereus spp.)seedlings.After analyzing the changes in gene expression caused by two different stresses using transcriptomic sequencing,it was discovered that while some genes ex-pressed similarly under both stresses and there were some shared regulatory pathways and signals,it was also dis-covered that some genes responded in opposite patterns,with the majority of differentially expressed genes being completely different.This work identified a high number of genes that respond to both pressures simultaneously,establishing a theoretical foundation for future development of broad-spectrum resistant dragon fruit cultivars.
