Physiological responses and Ethylene-Response AP2/ERF Factor expression in Indica rice seedlings subjected to submergence and osmotic stress.

Background: The increased frequency of heavy rains in recent years has led to submergence stress in rice paddies, severely affecting rice production. Submergence causes not only hypoxic stress from excess water in the surrounding environment but also osmotic stress in plant cells. We assessed physiological responses and Ethylene-Response AP2/ERF Factor regulation under submergence conditions alone and with ionic or nonionic osmotic stress in submergence-sensitive IR64 and submergence-tolerant IR64-Sub1 Indica rice cultivars.

Molecular Dissection of Resistance against by Grafting.

Vegetable crops of the genus are very popular worldwide and have great market value. However, their fruit quality and yield are hindered by viral diseases. is considered a wild species with resistance to viral diseases that is lacking in cultivated crops of the genus, such as melon.

The Seedlings of Different Rice Varieties Exhibit Differ Physiological Properties to Modulate Plant Survival Rates under Submergence Stress.

is a major food crop in Asia. In recent years, typhoons and sudden downpours have caused field flooding, which has resulted in serious harm to the production of rice. In this study, our data revealed that the plant heights of the five varieties increased during submergence.

ERF73/HRE1 is involved in HO production via hypoxia-inducible Rboh gene expression in hypoxia signaling.

Hypoxia deprives cells of energy and induces severe physical damage in embryophytes. Under hypoxia, the equilibrium between ethylene and HO affects the response of the transcription factor AtERF73/HRE1. To evaluate the role of AtERF73/HRE1 during hypoxia signaling, we used three independent AtERF73/HRE1 knockout lines to detect HO accumulation.
