The plant hormone ethylene is involved in many physiological processes , including plant growth , development and senescence . Ethylene also plays a pivotal role in plant response or adaptation under biotic and abiotic stress conditions . In plants , ethylene production often enhances the tolerance to sub-optimal environmental conditions . This role is particularly important from both ecological and agricultural point of views . Among the abiotic stresses , the role of ethylene in plants under nutrient stress conditions has not been completely investigated . In literature few reports are available on the interaction among ethylene and macro- or micro-nutrients . However , the published works clearly demonstrated that several mineral nutrients largely affect ethylene biosynthesis and perception with a strong influence on plant physiology . The aim of this review is to revisit the old findings and recent advances of knowledge regarding the sub-optimal nutrient conditions on the effect of ethylene biosynthesis and perception in plants . The effect of deficiency or excess of the single macronutrient or micronutrient on the ethylene pathway and plant responses are reviewed and discussed . The synergistic and antagonist effect of the different mineral nutrients on ethylene plant responses is critically analyzed . Moreover , this review highlights the status of information between nutritional stresses and plant response , emphasizing the topics that should be further investigated .
Solanum laciniatum Aiton treated with Gibberellic acid ( GA3 ) , [2-chloroethyl]-trimethyl ammonium chloride ( CCC ) , and their combinations at early and late stages of growth showed that early application of 2000 ppm CCC produced the greatest stem , leaves , and whole plant dry weight , followed by the combination of early application of 1000 ppm CCC and late application of 100 ppm GA3 ; whereas all GA3 treatments decreased the dry weight production compared with the controls . Regarding the glyco-alkaloids , the highest percentage was obtained from the whole plant by early applications of both strengths of GA3 compared with other treatments or the controls . On the other hand , early application of 1000 ppm CCC and also late application of 50 ppm GA3 when combined with early application of either 1000 ppm or 2000 ppm CCC produced greater alkaloid percentage yields in stem , leaves , and whole plants more than other treatments or the controls . However , early application of 2000 ppm CCC produced the highest content of alkaloids in leaves and whole plants ; this was followed by yields from early application of 2000 ppm CCC and 50 ppm GA3 ; yields from early application of 100 ppm GA3 and 1000 ppm CCC ; and yields from early application of 1000 ppm CCC + 50 ppm GA3 .
