Abstract:
Hypoxia stress can be caused by submergence or pathogen infection. These two stresses often occur sequentially or at the same time in nature. Therefore, plants have evolved economical and efficient strategies to deal with them, such as "single-gene multi-functions", that is, one gene could play roles in hypoxia or pathogen responses at the corresponding stress. This review mainly introduces the ERF-VII (ethylene response factor VII) and WRKYs (WRKY transcription factors) that can play roles in these two stresses. Meanwhile, the relationship between hypoxia and pathology has certain similarities in animals and plants, so we can learn from their related studies and develop new ideas for disease therapy and breeding.

Transcription
Transcription is the process of synthesizing RNA from a DNA sequence by RNA polymerase. It is the first step in producing a protein from a gene sequence. Additionally, many other proteins and regulatory sequences are involved in the proper synthesis of messenger RNA (mRNA). Regulation of transcription is responsible for the differentiation of all the different types of cells and often for the proper cellular response to environmental signals.
