Plants are independently exposed to one stress at a time but two or more stresses (independently) in their life cycle
1) Stress combinations are common, individual occurrence in isolation is rare
2) Can affect plant growth either positively or negatively, but in most cases act negatively

Photographs show increased susceptibility of chickpea plants to black root rot (Fusarium solani) under drought stress. Arrows indicate black root rot symptoms on plants
Arabidopsis plants show reduced growth and more chlorotic leaves under combined drought (40% field capacity) and pathogen (Pseudomonas syringae pv. tomato DC3000) stress compared to individual drought or pathogen stress
Tomato (Solanum lycopersicum) plants show less wilting symptoms under combined drought (40% field capacity) and xylem invading bacterial pathogen (Ralstonia solanacearum) stress compared to individual pathogen stress.

Welcome to SCIP database:
A comprehensive database for understanding combined stress response in plants

Under natural conditions, plants are exposed to a wide range of abiotic and biotic stress combinations, affecting their growth and yield. In most cases, the simultaneous or sequential occurrence of two different type of combined stresses affects a plant’s performance more severely than single stresses. For example, a combination of drought and heat stress caused more significant damage worth $200 billion to US agriculture than the $50 billion loss caused by drought alone (Mittler 2006;  Suzuki et al. 2014, Rivero et al, 2021, Zandalinas and Mittler 2022). Moreover, co-occurring abiotic stress can predispose a plant to several pathogens ( Sinha et al. 2019, Bidzinski et al. 2016). Overall, plant's response to combined stress is fairly distinct from its response to individual stress (Pandey et al. 2015,  2017, Choudhary et al. 2017, Gupta et al., 2016, 2017 , Sinha et al. 2017, Zandalinas et al. 2022). For a specific stress combination, both positive and negative interactions have been reported in the literature (reviewed in Pandey et al. 2015, 2017, Szczepaniec and Finke 2019, Desaint et al. 2020). Many studies on the effect of different stress combinations on plants often report contradictory results. This is because the outcome of an interaction between the two stresses varies with the plant age, plant type, time of stress occurrence, stress severity, duration of each stress, order of stress perceived by the plants, and also on the type of stressors involved. Under combined stress conditions, plants exhibit shared and unique responses tailored for the particular stress combination. This results in a high degree of complexity in plant's responses and makes it difficult to predict the outcome of an interaction based on single stress studies. A significant number of research groups worldwide investigate the individual and combined stress interactions (Desaint et al. 2020; Atkinson et al., 2012; Atkinson et al. 2013; Prasch and Sonnewald, 2013; Suzuki et al. 2014, Pandey et al. 2015, 2017, Choudhary and Senthil-Kumar). Considerable information has been accumulated over the years documenting the effect of combined stresses on plants. However, despite the increasing scientific interest in the field and the amount of data published, our understanding of nature and the physiological consequences of the interaction between two or more stresses remains poor. Even the data available is scattered and lacks systematic comparison. Moreover, the complexity of the plant's response makes it difficult to draw definitive conclusions out of the available data. To gain a deeper insight into the complexity of plant's response to combined stress, available literature information needs to be compiled and comprehensively analyzed. The current database provides exhaustive information on the available literature on different forms of combined stresses (simultaneous and sequential). In this database, we attempt to summarize the current knowledge and provide an update on recent findings, focusing on the morpho-physiological (phenome) and molecular (transcriptome) responses of the plant to a combination of different stresses and also for the individual stresses. The database would provide a powerful resource to analyze and compare plant responses during multifactorial stress and identify common and specific responses to different stress combinations.
