PmSOC1s and PmDAMs participate in flower bud dormancy of Prunus mume by forming protein complexes and responding to ABA
and dormancy processes, such as SUPPRESSOR OF OVEREXPRESSION OF CONSTANS 1 (SOC1) and Dormancy Associated MADS-box (DAM) genes. Here, the expression patterns of PmSOC1s and PmDAMs er bud dormancy were analyzed.

期刊介绍：
eJHS publishes original research articles and reviews on significant plant science discoveries and new or modified methodologies and technologies with a broad international and cross-disciplinary interest in the scope of global horticulture. eJHS focus is on applied and fundamental aspects of the entire food value chain, ranging from breeding, production, processing, trading to retailing of horticultural crops and commodities in temperate and Mediterranean regions. In particular eJHS emphasizes integrated crop management strategies during the preharvest and postharvest stages, aiming at sustainably increasing the quantity and quality of horticultural products. The eJHS publishes peer-reviewed articles, reviews and special thematic issues in the following science areas:
breeding and genetic resources;
clonal (micro)propagation and seed physiology;
cropping systems, including crop management practices;
plant/fruit growth and development, including interactions with environments and organisms;
plant protection and plant nutrition;
irrigation and plant water relation;
whole plant physiology and source/sink relation;
urban horticulture/protected cultivation;
fruit ripening and product quality;
storage technologies, including postharvest disorders;
food processing technologies/horticultural engineering;
marketing/economics;
education and consultancy;
consumer sciences.
