Effects of Differential Expression of Monosaccharide Transporter Genes on Yield Formation of Virus-free Sugarcane Seedlings

The yield increase effect was analyzed by planting disease-free sugarcane seedlings, and the differential expression of three monosaccharide transport- er genes （ SGT1, SGT2 and PST2a） in disease-free and untreated sugarcane seedlings was studied to clarify the functions of these genes on sugarcane...

Summary:The yield increase effect was analyzed by planting disease-free sugarcane seedlings, and the differential expression of three monosaccharide transport- er genes （ SGT1, SGT2 and PST2a） in disease-free and untreated sugarcane seedlings was studied to clarify the functions of these genes on sugarcane yield. The yield was increased by 27.2% by planting disease-free sugarcane seedlings. The expression levels of SGT1, SGT2 and PST2a in leaves of virus-free plants were 1 - 20 times higher than those in untreated sugarcane plants during the whole growth period. In addition, the expression levels of SGT1 and SGT2 in 1 - 8 inter- nodes of sugarcane at elongation stage and maturity stage were 1 - 45 times higher than those in untreated plants. And the expression levels of PST2a in 4 - 8 in- teruodes of sugarcane plants at elongation stage were 4 - 7 times higher than those in untreated plants, but there was no difference in expression levels at maturity stage. The functions of different monosaccharlde transporters varied among different growth stages. The three kinds of monosaccharide transporters might form a mutual cooperation network, and improved monosaccharide transport efficiency by increasing their self activity to provide more monosaccharide for cell metabo- lism, favorable for the yield increase of sugarcane stem.
