WebTwo key cold tolerance genes were sampled, ICE1 and HOS1.As stated before, ICE1 is a fundamental upstream gene in theCBF expression cascade that induces several cold acclimation re-sponses, while HOS1 negatively regulates ICE1 transcripts, acting to decrease cold tolerance (reviews in Chinnusamy et al. 2007; Miura and Furumoto 2013). WebJun 12, 2024 · Arabidopsis HOS1 was the first RING-type E3 ubiquitin ligase to act as a negative regulator of cold responses (Jung et al., 2014). Under normal growth conditions, HOS1 did not affect the nuclear localization and the abundance of GFP-ICE1, while HOS1 can interact with and ubiquitinate ICE1 for degradation under cold stress (Dong et al., 2006).

WebMar 1, 2024 · Specifically, the OST1 interacts with HOS1 to interfere with its interaction with the ICE1, inhibiting ubiquitination degradation of the ICE1 (Luo et al., 2024). Research has evidenced that ICE1 degradation is significantly inhibited under low-temperature stress with the expression of hos1 mutants, enhancing the expression of ICE1 in transgenic ...
