Arbuscular mycorrhizal fungi (AMF) are known to improve plant stress tolerance by regulating proline accumulation, and nitric oxide (NO) plays an important signaling role in proline metabolism. Environmental nitrogen (N) affects AMF colonization and its contribution to host plants resistance to stress conditions. However, the relationship between proline metabolism and NO in mycorrhizal rice and the effect of N application on symbiont proline metabolism under low temperature have not been established.

The results showed that the HNO-modified zeolite loaded with FeOOH@ZnO (FeOOH@ZnO/HZ) resulted in a maximum S removal rate of ≈98%. The adsorbent's performance on removing S was significantly enhanced, compared with NaOH and ZnCl-modified zeolites loaded with FeOOH@ZnO, and the adsorption was proved to be a heat-absorbing process.

Consequently, Zn application after low temperature might be an effective approach to promote rice tiller recovery.
