Abstract
Editorial: Ethylene's Role in Plant Mineral Nutrition.
Highlights

The production of ethylene is tightly regulated by internal signals, and usually increases in response to biotic and abiotic stresses, such as mechanical stress, hypoxia, chilling, and nutritional disorders (Abeles et al, 1992; Lynch and Brown, 1997; Concellon et al, 2005; Zheng et al, 2008; Geisler-Lee et al, 2010; Iqbal et al, 2013; García et al, 2015)
In processes related to mineral nutrition, ethylene has been implicated in the regulation of physiological and morphological responses to nutrient deficiencies; in nodulation of legume plants; in salt tolerance responses; and in responses to heavy metals (Abeles et al, 1992; Lynch and Brown, 1997; García et al, 2015)
Summary
Reviewed by: Marta Dell’Orto, Università degli Studi di Milano, Italy Marta R. In processes related to mineral nutrition, ethylene has been implicated in the regulation of physiological and morphological responses to nutrient deficiencies; in nodulation of legume plants; in salt tolerance responses; and in responses to heavy metals (Abeles et al, 1992; Lynch and Brown, 1997; García et al, 2015). This research topic updates recent results relating ethylene to different aspects of plant mineral nutrition It includes 10 reviews and 2 original articles: 7 reviews are related to nutrient deficiencies (Khan et al.; Lucena et al.; Schachtman; Song and Liu; Wawrzynska et al.; González-Fontes et al.; Neumann), 1 to nodulation (Guinel), 1 to salt tolerance (Tao et al.), and 1 to heavy metals (Keunen et al.); 1 original article is related to Fe (iron) deficiency (Ye et al.), and the other one to N (nitrogen) deficiency (De Gernier et al.). In the case of N, the relationship between its deficiency and ethylene production seems to be complex, affected by the degree of the deficiency and the plant genotype (Khan et al.; De Gernier et al.)
