Abstract: Drought is one of the most serious natural disasters faced by human beings, and also the most important environmental factor affecting crop production. Zinc finger protein refers to a class of proteins containing zinc ion and finger-like domains. It is the most common type of transcription factor found in plants and plays the most important role in plant drought response. Di19 is a newly discovered small zinc finger protein containing two C2H2 type zinc finger domains, which is induced by drought and high salt, and plays an active role in plant drought response. Soybean roots are underdeveloped, require more water, sensitive to drought, and water deficit is the most important environmental factor that restricts their yield and quality. In this paper, the research status of soybean drought tolerance, the role of zinc finger protein and its newest member Di19 in drought tolerance response of soybean were reviewed in order to provide reference for drought tolerance improvement of soybean.

Key words: zinc finger protein, transcription factor, Di19 (Drought induce 19), soybean, drought stress
