Abstract:
A dwarf sunflower variety from ornamental sunflower (Helianthus annuus L.) was used as the test material.By inducing Sclerotinia sclerotiorum to the four-leaf stage ornamental sunflower,RNA was extracted for reverse transcription，PCR fluorescence quantitative methods to study the expression of defense-related genes and to investigate the effect of pantococcus radiodurans on the expression of defense-related genes in ornamental sunflowers.The results showed that Sclerotinia sclerotiorum infection upregulated the expression levels of key genes [STBX]NPR1 and PR1[STBZ] in the SA signaling pathway of ornamental sunflowers;the expression level of key genes [STBX]PDF1.2[STBZ] in the ET-mediated signal transmission pathway increases;JA the expression of the key “node” genes [STBX]MPK4 and EDS1[STBZ] in the ET pathway was up-regulated;[STBX]NPR1,PR1,EDS1,PDF1.2 and MPK4[STBZ] were significantly up-regulated,indicating that ornamental sunflower is regulated by SA and JA signals,and S.sclerotiorum had a certain influence to the expression of defense genes related to ornamental sunflower.
