Current understanding on ethylene signaling in plants : The influence of nutrient availability / N. Iqbal, A. Trivellini, A. Masood, A. Ferrante, N.A. Khan. - In: PLANT PHYSIOLOGY AND BIOCHEMISTRY. - ISSN 0981-9428. - 73:(2013), pp. 128-138. [10.1016/j.plaphy.2013.09.011]
Abstract:
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 suboptimal
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.
