“…Leaves are known to be highly plastic in response to variations in nutrient and/or moisture availability, varying greatly in anatomy, morphology, and physiology (Lu et al 2019). In our study, the thicknesses of leaf, palisade tissue, epidermis, and the P/S ratio were all positively correlated with N application rate under HW conditions (Table 1).…”

“…This anatomical trade-off (investment in photosynthetic machinery vs. protective tissues) in our study indicates that N30 plants are more susceptible to drought stress. Apparently, N application per se did not demonstrate the positive role in anatomical changes of S. suberectus leaf upon drought stress, as reported in Populus (Lu et al 2019).…”

A pot study was conducted to elucidate morphological and physiological responses of Spatholobus suberectus Dunn accessions to four nitrogen application rates (0, 10, 20, and 30 mmol L-1) and two watering regimes (daily irrigation and irrigation every 10 d for a month). The results showed that water deficit led to marked decreases in leaf water relations and photosynthetic parameters regardless of the N treatments. Under drought conditions, the reductions in net photosynthesis occurred mainly due to stomatal factors. Although the leaf N content and stem mass ratio were positively correlated with N application, other morphological and physiological characteristics were negatively correlated or nonsignificantly correlated with N application under limited water supply. As the root nodules of S. suberectus can provide sufficient N supply, and high N applications made S. suberectus plants more vulnerable to drought stress, we suggest that no N supplement is required for S. suberectus seedlings.

“…However, when a moderate drought stress is applied, no reduction in the capacity to acquire N is observed (Buljovcic and Engels, 2001). Adequate supply of N also enhances drought tolerance in poplars, improving the water uptake by the root system (Lu et al, 2019). In maize, the tolerance to the stress combination of N deficiency and drought seems to be cultivar-dependent and correlates with genotypes with enlarged root system (Eghball and Maranville, 1993).…”

Effects of Combined Abiotic Stresses Related to Climate Change on Root Growth in Crops

2022

Climate change is a major threat to crop productivity that negatively affects food security worldwide. Increase in global temperatures are usually accompanied by drought, flooding and changes in soil nutrients composition that dramatically reduced crop yields. Against the backdrop of climate change, human population increase and subsequent rise in food demand, finding new solutions for crop adaptation to environmental stresses is essential. The effects of single abiotic stress on crops have been widely studied, but in the field abiotic stresses tend to occur in combination rather than individually. Physiological, metabolic and molecular responses of crops to combined abiotic stresses seem to be significantly different to individual stresses. Although in recent years an increasing number of studies have addressed the effects of abiotic stress combinations, the information related to the root system response is still scarce. Roots are the underground organs that directly contact with the soil and sense many of these abiotic stresses. Understanding the effects of abiotic stress combinations in the root system would help to find new breeding tools to develop more resilient crops. This review will summarize the current knowledge regarding the effects of combined abiotic stress in the root system in crops. First, we will provide a general overview of root responses to particular abiotic stresses. Then, we will describe how these root responses are integrated when crops are challenged to the combination of different abiotic stress. We will focus on the main changes on root system architecture (RSA) and physiology influencing crop productivity and yield and convey the latest information on the key molecular, hormonal and genetic regulatory pathways underlying root responses to these combinatorial stresses. Finally, we will discuss possible directions for future research and the main challenges needed to be tackled to translate this knowledge into useful tools to enhance crop tolerance.

“…Based on the salinity stress is considered one of the most common and important abiotic stress worldwide, a survey on the anatomical behavior of some cultivated plants under salinity stress was listed in Table 2. Recently, more studies have published including the anatomy of different cultivated plants under stress such asheat stress on Rhododendron (Shen et al 2017), flooding on poplar (Peng et al 2017), waterlogging on pigeonpea or on wheat (Shen et al 2020), drought stress on Eucalyptus (Otto et al 2017) or sorghum (Guha et al 2018) or poplar (Lu et al 2019), Schinus molle under lead stress (Ribeiro et al 2019), water deficit on pigeonpea or gum tree (Lobato et al 2020;Bueno et al 2020), zinc (Zn) stress on soybean (dos , copper stress on barley (Minkina et al 2020) and lead stress on some plants (Adejumo et al 2020). Whereas, some plants like Jerusalem artichoke have cultivated under many stresses like stress low temperatures (Mu et al 2021), salinity (Shao et al 2016(Shao et al , 2019Fang et al 2018;Luo et al 2018;Yue et al 2020;Zou et al 2020;Zhu et al 2021), water stress (Ruttanaprasert et al 2016), drought (Puangbut et al 2017) and waterlogging ).…”

G LOBAL food production and its quality face a lot of challenges, which already decreased the availability of these foods. These challenges were mainly linked to global climate changes and their ramifications, which are expressed as environmental stresses like drought, flooding, low or high heat stress. The new pandemics like COVID-19 also represent a new challenge for the entire world. Although, there are increasing concerns about combined stress on cultivated plants, more studies are still needed to cover botanical issues including physiological, morphological, biochemical and histological traits. Further studies are required to focus on different combined or multiple stresses in particular the individual stress is rare in the nature. This is an invitation for publication reviews, comments, notes and original articles about the anatomical changes in stressful plants particularly under combined stress. The EBSS journal also welcomes the serious and promising studies, which will handle the environmental issues related to stress in the era of
