Abstract:

In this paper, the effects of abiotic stress on the growth and development, physiological and biochemical characteristics and molecular level of sugar beet were reviewed from four aspects: drought and flood, salinity and alkali, high and low temperature and soil heavy metal pollution. The results show that under abiotic stress, the net photosynthetic rate of sugar beet decreases, the concentration of osmotic regulation substances changes, the content of active oxygen metabolites alters, and the growth and development of sugar beet are affected. Sugar beet water stress resistance genes include PSC5, PSCR, 2-cysprx, NADK, cprx1, AVP1, Bv-txas and etc., MYB transcription factors and NAC transcription factors also play an important role in abiotic stress resistance. Beet M14 strain has excellent characteristics of drought resistance and salt tolerance. WRKY family transcription factors, BvM14-Tpx, BvM14-CCoAOMT and other genes, peroxidase BvpAPX and various salt response proteins play promoting roles in salt stress resistance. There are few studies on the resistance of sugar beet to high and low temperature. Studies show that low temperature stress produces differential expression of bolting gene in sugar beet. SbSEC14 gene also plays a signal transduction function under stress conditions. The research on sugar beet resistance to heavy metal stress has developed rapidly in recent years, the BvGS, BvMTP11, BvHIPP24 and BvGST genes have been cloned successively. This paper suggests that the mechanism of anti-abiotic stress in sugar beet and its application should be further explored and innovated in the future. Fully excavating DREB gene in wild species and breeding beet varieties (lines) with strong stress resistance through transgenic technology should be conducted. On the basis of the study of single stress, the study of stress resistance under multiple stresses should be further carried out. In production, exogenous regulators, antioxidants and silicon should be used to resist the effects of abiotic stress on the growth and development of sugar beet.

Key words: sugar beet, moisture, drought, salinity and alkali, temperature, heavy metal pollution, abiotic stress of sugar beet.
