“…The response of ETH to salt stress varies greatly among different plants [ 6 ]. For instance, ETH signal transduction has been confirmed to promote salt tolerance in Arabidopsis , but in rice, ETH signals negatively regulate salt tolerance [ 59 , 60 ]. In Arabidopsis , ETR1, EIN4, and ETH, which are negative regulators of CTR1 mutations, enhance salt tolerance [ 31 , 32 , 61 , 62 , 63 ], while mutants of the ETH-positive regulators EIN2 and EIN3/EIL1 are more sensitive to salt [ 32 , 64 ].…”

Salt stress seriously restricts crop yield and quality, leading to an urgent need to understand its effects on plants and the mechanism of plant responses. Although phytohormones are crucial for plant responses to salt stress, the role of phytohormone signal transduction in the salt stress responses of stress-resistant species such as Sophora alopecuroides has not been reported. Herein, we combined transcriptome and metabolome analyses to evaluate expression changes of key genes and metabolites associated with plant hormone signal transduction in S. alopecuroides roots under salt stress for 0 h to 72 h. Auxin, cytokinin, brassinosteroid, and gibberellin signals were predominantly involved in regulating S. alopecuroides growth and recovery under salt stress. Ethylene and jasmonic acid signals may negatively regulate the response of S. alopecuroides to salt stress. Abscisic acid and salicylic acid are significantly upregulated under salt stress, and their signals may positively regulate the plant response to salt stress. Additionally, salicylic acid (SA) might regulate the balance between plant growth and resistance by preventing reduction in growth-promoting hormones and maintaining high levels of abscisic acid (ABA). This study provides insight into the mechanism of salt stress response in S. alopecuroides and the corresponding role of plant hormones, which is beneficial for crop resistance breeding.

“…In addition, the expression levels of OsEIL2 were found to be upregulated during salinity stress in WT plants; however, OsEIL2 overexpression plants showed growth retardation with shortened roots and shoots than control plants [70]. In addition, OsEIL2 overexpression plants showed increased ethylene sensitivity and accelerated leaf senescence [70]. Further, it has been observed that OsEIL2 negatively regulates the expression of BURP genes OsBURP14 and OsBURP16 to reduce the pectin content during salinity stress in rice [70].…”

Ethylene: A Master Regulator of Salinity Stress Tolerance in Plants

Salinity stress is one of the major threats to agricultural productivity across the globe. Research in the past three decades, therefore, has focused on analyzing the effects of salinity stress on the plants. Evidence gathered over the years supports the role of ethylene as a key regulator of salinity stress tolerance in plants. This gaseous plant hormone regulates many vital cellular processes starting from seed germination to photosynthesis for maintaining the plants’ growth and yield under salinity stress. Ethylene modulates salinity stress responses largely via maintaining the homeostasis of Na+/K+, nutrients, and reactive oxygen species (ROS) by inducing antioxidant defense in addition to elevating the assimilation of nitrates and sulfates. Moreover, a cross-talk of ethylene signaling with other phytohormones has also been observed, which collectively regulate the salinity stress responses in plants. The present review provides a comprehensive update on the prospects of ethylene signaling and its cross-talk with other phytohormones to regulate salinity stress tolerance in plants.

“…Overexpression of the ARGOS genes improves drought tolerance in both Arabidopsis and maize (Shi et al, 2015(Shi et al, , 2016c. In contrast, overexpression of OsEIL2 caused reduced drought tolerance compared with that of control rice, suggesting that ethylene signaling negatively regulates drought tolerance of rice (Jin et al, 2020). Downstream of ethylene signaling, several ERF genes have been reported to be involved in drought tolerance.…”

Ethylene is a gaseous hormone which plays important roles in both plant growth and development and stress responses. Based on studies in the dicot model plant species Arabidopsis, a linear ethylene signaling pathway has been established, according to which ethylene is perceived by ethylene receptors and transduced through CONSTITUTIVE TRIPLE RESPONSE 1 (CTR1) and ETHYLENE‐INSENSITIVE 2 (EIN2) to activate transcriptional reprogramming. In addition to this canonical signaling pathway, an alternative ethylene receptor‐mediated phosphor‐relay pathway has also been proposed to participate in ethylene signaling. In contrast to Arabidopsis, rice, a monocot, grows in semiaquatic environments and has a distinct plant structure. Several novel regulators and/or mechanisms of the rice ethylene signaling pathway have recently been identified, indicating that the ethylene signaling pathway in rice has its own unique features. In this review, we summarize the latest progress and compare the conserved and divergent aspects of the ethylene signaling pathway between Arabidopsis and rice. The crosstalk between ethylene and other plant hormones is also reviewed. Finally, we discuss how ethylene regulates plant growth, stress responses and agronomic traits. These analyses should help expand our knowledge of the ethylene signaling mechanism and could further be applied for agricultural purposes.
