“…It also influences seed germination ( Ribeiro et al, 2018 ), seedling growth ( Gniazdowska et al, 2010 ), sex expression (especially female flower formation in cucumber) ( Pawełkowicz et al, 2019 ), fruit ripening ( Mou et al, 2016 ), secondary cell wall formation ( Felten et al, 2018 ), the growth of pollen tubes ( Jia et al, 2018 ), root cortical senescence ( Schneider et al, 2018 ), and the rate of photosynthesis ( Khan et al, 2016 ). Ethylene also plays an essential role in plant response and adaptation to biotic and abiotic stress conditions ( Tao et al, 2015 ), including cadmium stress ( Alves et al, 2017 ), water deficit stress ( Gao et al, 2017 ), waterlogging stress ( Luan et al, 2018 ), UV-B stress ( Prudnikova et al, 2016 ) and magnesium deficiency ( Liu et al, 2017 ). Ethylene also promotes the initiation of lateral root primordia derived from the pericycle as well as the emergence and elongation of lateral roots.…”

The mechanisms involved in adventitious root formation reflect the adaptability of plants to the environment. Moreover, the rooting process is regulated by endogenous hormone signals. Ethylene, a signaling hormone molecule, has been shown to play an essential role in the process of root development. In the present study, in order to explore the relationship between the ethylene-induced adventitious rooting process and photosynthesis and energy metabolism, the iTRAQ technique and proteomic analysis were employed to ascertain the expression of different proteins that occur during adventitious rooting in cucumber (Cucumis sativus L.) seedlings. Out of the 5,014 differentially expressed proteins (DEPs), there were 115 identified DEPs, among which 24 were considered related to adventitious root development. Most of the identified proteins were related to carbon and energy metabolism, photosynthesis, transcription, translation and amino acid metabolism. Subsequently, we focused on S-adenosylmethionine synthase (SAMS) and ATP synthase subunit a (AtpA). Our findings suggest that the key enzyme, SAMS, upstream of ethylene synthesis, is directly involved in adventitious root development in cucumber. Meanwhile, AtpA may be positively correlated with photosynthetic capacity during adventitious root development. Moreover, endogenous ethylene synthesis, photosynthesis, carbon assimilation capacity, and energy material metabolism were enhanced by exogenous ethylene application during adventitious rooting. In conclusion, endogenous ethylene synthesis can be improved by exogenous ethylene additions to stimulate the induction and formation of adventitious roots. Moreover, photosynthesis and starch degradation were enhanced by ethylene treatment to provide more energy and carbon sources for the rooting process.
