Gene Details:

• Gene ID: Zm00001eb380410
• Gene Symbol: ZmHSBP2 hsbp2
• Gene Name: HEAT SHOCK BINDING PROTEIN 2
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• We report here that maize HEAT SHOCK FACTOR A2 (ZmHSFA2) and HEAT SHOCK BINDING PROTEIN 2 (ZmHSBP2) physically interact with each other and antagonistically modulate expression of GALACTINOL SYNTHASE2 (ZmGOLS2) and raffinose biosynthesis in transformed maize protoplasts and Arabidopsis plants.
• Accumulation of EMP2 and ZmHSBP2 differs in different maize tissues or in response to heat stress
• ZmHSFA2 and ZmHSBP2 regulate raffinose biosynthesis and plant heat stress tolerance in maize.
• The ZmHSFA2 and ZmHSBP2 proteins work together to positively or negatively, respectively, regulate raffinose biosynthesis and plant heat stress tolerance.
• ZmHSBP2 physically interacts with ZmHSFA2 and antagonistically modulates raffinose biosynthesis and plant tolerance of heat stress.
