Isolation and characterization of wheat ice recrystallisation inhibition gene promoter involved in low temperature and methyl jasmonate responses.

It is well known that plant growth, development, survival and geographical distribution are constrained by extreme climatic conditions, especially extreme low temperature. Under cold stress, cold-inducible promoters were identified as important molecular switches to transcriptionally regulate the initiation of genes associated with cold acclimation processes and enhance the adaptability of plants to cold stimulation. Wheat ( L.

Identification of genes from the ICE-CBF-COR pathway under cold stress in - composite group and the evolution analysis with those from .

Adverse environmental conditions limit various aspects of plant growth, productivity, and ecological distribution. To get more insights into the signaling pathways under low temperature, we identified 10 C-repeat binding factors (), 9 inducer of CBF expression () and 10 cold-responsive () genes from - composite group under cold stress. Conserved amino acids analysis revealed that all CBF, ICE, COR contained specific and typical functional domains.

Gene Regulation and Signal Transduction in the ICE-CBF-COR Signaling Pathway during Cold Stress in Plants.

Low temperature is an abiotic stress that adversely affects the growth and production of plants. Resistance and adaptation of plants to cold stress is dependent upon the activation of molecular networks and pathways involved in signal transduction and the regulation of cold-stress related genes. Because it has numerous and complex genes, regulation factors, and pathways, research on the ICE-CBF-COR signaling pathway is the most studied and detailed, which is thought to be rather important for cold resistance of plants.
