Abstract:

In order to explore the effect of RNA extraction and virus detection of different parts of apple organs,apple plants infected by three viruses were used as experimental materials.Adsorption column method was used to extract total RNA from flowers(pistil,anther,filament,petals,calyx,receptacle,and flower stalk),leaves(petiole,mesophyll,and veins),fruits(fruit stalk,peel,flesh,score,episperm,and endosperm)and branches(phloem),a total of 17 tissues of four organs.The extraction effects of different sampling parts were compared,the detection effects of three viruses in different parts of organs were analyzed by regular RT-PCR,and the relative content of viruses in different parts of organs were analyzed by Real-time fluorescence quantitative PCR.The results showed that the effects of RNA extraction from different organs of apple were different,with the highest concentration in leaves,followed by flowers and phloem of branches,and the lowest concentration in fruits.Anther,filament and petiole were best extracted from flowers and endosperm and petiole were best extracted from fruits and leaves,respectively.Three apple viruses could be detected in 16 tissues except endosperm.Quantitative analysis showed that the relative content of the three apple viruses was the highest in flowers.Furthermore,the relative contents of viruses in pistil,episperm and petiole were correspondingly higher than that in other tissue parts of flower,fruit and leaf,respectively.In addition,the content of the three viruses in different tissue parts of fruits and leaves showed similar trends,but there were certain differences in the distribution of different tissue parts of flowers.
