Comparative transcriptome analysis reveals synergistic and disparate defense pathways in the leaves and roots of trifoliate orange (Poncirus trifoliata) autotetraploids with enhanced salt tolerance

摘要

– Phenotype ( ), chlorophyll content ( ) and MDA content ( ) of three-month-old diploid and tetraploid plants after two weeks of culture in salt solution or water (control). Phenotype of seven-month-old potted seedlings after 30 days of irrigation with salt solution or water (control). – Phenotype ( ), chlorophyll content ( ) and electrolyte leakage ( ) of fresh shoots obtained from 2-year-old diploid and tetraploid plants before and/or after salt treatment. Trypan Blue staining of diploid and tetraploid leaves with or without (control) salt treatment. Error bars indicate SE (  = 3). Asterisks indicate significant differences between the diploids and tetraploids (*  P P
