Virus-free sugarcane seedlings have improved biomass and sucrose content compared with ordinary seedlings,and sucrose invertases are key enzymes regulating sugarcane growth and sucrose accumulation.In this study,the differences in the expression levels of 3 invertase genes,CWI,SAI and NI,between virusfree and ordinary sugarcane seedlings were analyzed.Compared with ordinary sugarcane plants,the expression of CWI was mainly up-regulated in immature leaves and stems at elongation stage and leaves and immature internodes at maturation stage,and especially,greatly up-regulated in immature internodes at maturation stage of virus-free plants.The expression of SAI and NI were mainly up-regulated in leaves and immature internodes of virus-free plants at maturation stage,which might be beneficial to sugar accumulation and rapid utilization of monosaccharide in the stalks of virus-free plants.It is further indicated that virus-free treatment could significantly improve the expression of sucrose invertases at late growth period,and might facilitate the increase of plant biomass. 展开更多

Antagonistic bacterium HJX1 is a Bacillus subtilis strain isolated from field rhizosphere soil where banana wilt was serious,with certain control efficacy on banana Fusarium wilt.The crude extract obtained from its fermentation broth after ammonium sulfate precipitation has an inhibitory effect on various pathogenic fungi.The culture conditions for this strain were optimized in this study with Fusarium oxysporum f.sp.cubense as an indicator,and the results showed that the fermentation broth obtained from culture in LB liquid medium under 30 ℃ at 170 r / min for 48 h had the strongest inhibition against F.oxysporum f.sp.cubense.It was observed that the inhibition was mainly reflected by causing breakage and distortion of mycelia,followed by appearance of vesicles and swelling,ablation,and leakage of protoplasm.This study provides a scientific basis for the study on the action mechanism of crude protein from bacterial strain HJX1. 展开更多

The pathogen and characteristics, infection cycle, occurrence regularity and damage symptoms of sugarcane smut were introduced in the paper. Moreover, the comprehensive prevention measures were proposed on the basis of planting disease-resistant species, strengthening cultivation managements to improve disease-resistant ability of sugarcane, and adopting fungicide control as assistant measures. The study provided certain basis for reducing damages of sugarcane smut and improving yield and quality of sugarcane. 展开更多
