“…Small changes in temperature, sensed by PhyB and phototropins (Jung et al, 2016;Legris et al, 2016;Fujii et al, 2017), partly inhibit photomorphogenesis in young seedlings. This so-called thermomorphogenic response includes elongated hypocotyls and epinastic cotyledons, and serves to enhance cooling of the young leaves and thus warmth adaptation (for review, see van Zanten et al, 2014;Quint et al, 2016). The key factor in this warmthmediated arrest on de-etiolation is PIF4.…”

“…In recent decades, knowledge on the effect of abiotic stresses on plant survival (tolerance) has advanced significantly but is primarily based on studies focusing on a single stress. Some of these studies have looked into the performance of plants under sublethal stresses, such as mild supra-optimal temperatures, shallow submergence in the light or mild drought ( Blum and Jordan 1985 ; Chapin 1991 ; Van Zanten et al 2013 ). However, a comprehensive understanding of plant performance under sublethal abiotic stresses requires analysing coordinated changes in functional traits both during the occurrence of stress and upon stress recovery, as opposed to one trait at a time ( Tardieu and Tuberosa 2010 ; Pandey et al 2017 ; Thoen et al 2017 ).…”

“…In Arabidopsis thaliana ( Arabidopsis ), a mild increase in temperature is known to affect multiple traits such as leaf angle, petiole length, leaf shape, specific leaf area or flowering time ( Van Zanten et al 2013 ; Jagadish et al 2016 ; Quint et al 2016 ; Casal and Balasubramanian 2019 ). Drought may affect allocation of assimilates to roots, leaf relative water content and leaf expansion ( Chaves et al 2003 ; Tardieu et al 2018 ).…”

Effects of sublethal single, simultaneous and sequential abiotic stresses on phenotypic traits of Arabidopsis thaliana

Plant responses to abiotic stresses are complex and dynamic, and involve changes in different traits, either as the direct consequence of the stress, or as an active acclimatory response. Abiotic stresses frequently occur simultaneously or in succession, rather than in isolation. Despite this, most studies have focused on a single stress and single or few plant traits. To address this gap, our study comprehensively and categorically quantified the individual and combined effects of three major abiotic stresses associated with climate change (flooding, progressive drought and high temperature) on 12 phenotypic traits related to morphology, development, growth and fitness, at different developmental stages in four Arabidopsis thaliana accessions. Combined sublethal stresses were applied either simultaneously (high temperature and drought) or sequentially (flooding followed by drought). In total, we analysed the phenotypic responses of 1782 individuals across these stresses and different developmental stages. Overall, abiotic stresses and their combinations resulted in distinct patterns of effects across the traits analysed, with both quantitative and qualitative differences across accessions. Stress combinations had additive effects on some traits, whereas clear positive and negative interactions were observed for other traits: 9 out of 12 traits for high temperature and drought, 6 out of 12 traits for post-submergence and drought showed significant interactions. In many cases where the stresses interacted, the strength of interactions varied across accessions. Hence, our results indicated a general pattern of response in most phenotypic traits to the different stresses and stress combinations, but it also indicated a natural genetic variation in the strength of these responses. This includes novel results regarding the lack of a response to drought after submergence and a decoupling between leaf number and flowering time after submergence. Overall, our study provides a rich characterization of trait responses of Arabidopsis plants to sublethal abiotic stresses at the phenotypic level and can serve as starting point for further in-depth physiological research and plant modelling efforts.

“…Plants are continuously exposed to fluctuating temperatures and need to respond appropriately to diverse cues, from freezing to heat stress (Penfield, 2008;Van Zanten et al, 2014;Casal and Balasubramanian, 2019;Ding et al, 2020). With a few exceptions, plants lack homeostatic mechanisms to maintain body temperature, while almost every process in the plant depends on temperature (Penfield, 2008;Quint et al, 2016;Ibañez et al, 2017).…”

“…These function as molecular chaperones to protect native proteins and remove proteins that are damaged beyond repair (Wahid et al, 2007;Zhao et al, 2021). On the physiological level, the balance between carbon gain through photosynthesis and carbon loss through respiration is affected by temperature (Atkin and Tjoelker, 2003;Van Zanten et al, 2014;Perez and Feeley, 2020), and carbon (sugar) status regulates growth responses triggered by high ambient temperature conditions (Hwang et al, 2019).…”

Various strategies evolved in plants to adjust the position of organs relative to the prevailing temperature condition, which allows optimal plant growth and performance. Such responses are classically separated into nastic and tropic responses. During plant thermotropic responses, organs move towards (engage) or away (avoid) from a directional temperature cue. Despite thermotropism being a classic botanical concept, the underlying ecological function and molecular and biophysical mechanisms remain poorly understood to this day. This contrasts to the relatively well-studied thermonastic movements (hyponasty) of e.g., rosette leaves. In this review, we provide an update on the current knowledge on plant thermotropisms and propose directions for future research and application.
