“…Thus, soil waterlogging is an important factor affecting the growth, development and survival of numerous plant species, not only in natural ecosystems but also in agricultural and horticultural systems. 4,5 Waterlogging occurs when water fills a critical proportion of the soil air spaces, depending on the plant species of plant involved. During waterlogging, inhibition of root respiration and subsequent to the root tissue has been suggested as cause of flooding stress.…”

Under natural conditions, plants are frequently exposed to transient or permanent soil waterlogging. Flooding of the soil with water with poor drainage drastically influences the soil physico-chemical properties, most notably soil oxidation-reduction potential, pH and O2 level. Thus, conditions of hypoxia or anoxia are commonly encountered by plant root systems. These O2 restrictive conditions dramatically have an effect on plant growth, development and survival. One in every of the simplest characterized plant responses to soil waterlogging is that the metabolic switch from aerobic respiration to anaerobic fermentation. In this study the effects of waterlogged were examined on seedling growth, metabolic, physiological and morphological responses of five species of timber trees (Casuarina cunninghamiana, C. glauca, Eucalyptus rostrata, Cupressus sempevirens and E. citrodora). The results indicated a wide variation among these timber tree species in their response to water logging. Casuarina cunninghamiana and C. glauca were more tolerant to waterlogging than the other species, followed by Eucalyptus rostrata then Cupres sussempevirens. E. citrodora was the least tolerant waterlogging species. Waterlogging treatment decreased the seedling growth and the leaf contents from carbohydrates, total and free phenols, chlorophylls and carotenoids as well as N, P and K contents in the leaves. On the other hand, waterlogging treatment increased both epinastic leaf angles, contents of total indoles, total free amino acids, chloride, sodium, calcium and magnesium in the leaves. Moreover, total free amino acids, total indoles, carbohydrates, total and free phenols contents were also increased in stems and roots of waterlogged seedlings.

“…The generation of morpho-anatomical modifications has been observed in different fruit tree species. Hypoxia-tolerant apple rootstocks generated adventitious roots in response to intermittent waterlogging events [ 88 ]. The development of hypertrophied lenticels as a response to root hypoxia has been reported in Rosaceae species such as Pyrus spp.…”

Plants are permanently facing challenges imposed by the environment which, in the context of the current scenario of global climate change, implies a constant process of adaptation to survive and even, in the case of crops, at least maintain yield. O2 deficiency at the rhizosphere level, i.e., root hypoxia, is one of the factors with the greatest impact at whole-plant level. At cellular level, this O2 deficiency provokes a disturbance in the energy metabolism which has notable consequences on the yield of plant crops. In this sense, although several physiological studies describe processes involved in plant adaptation to root hypoxia in woody fruit trees, with emphasis on the negative impacts on photosynthetic rate, there are very few studies that include -omics strategies for specifically understanding these processes in the roots of such species. Through a de novo assembly approach, a comparative transcriptome study of waterlogged Prunus spp. genotypes contrasting in their tolerance to root hypoxia was revisited in order to gain a deeper insight into the reconfiguration of pivotal pathways involved in energy metabolism. This re-analysis describes the classically altered pathways seen in the roots of woody fruit trees under hypoxia, but also routes that link them to pathways involved with nitrogen assimilation and the maintenance of cytoplasmic pH and glycolytic flow. In addition, the effects of root hypoxia on the transcription of genes related to the mitochondrial oxidative phosphorylation system, responsible for providing adenosine triphosphate (ATP) to the cell, are discussed in terms of their roles in the energy balance, reactive oxygen species (ROS) metabolism and aerenchyma formation. This review compiles key findings that help to explain the trait of tolerance to root hypoxia in woody fruit species, giving special attention to their strategies for managing the energy crisis. Finally, research challenges addressing less-explored topics in recovery and stress memory in woody fruit trees are pointed out.

“…G202, G214, and G935 rootstocks also improved the tolerance of ‘Fuji’ to drought stress than M26 and CG5087 rootstocks through maintaining leaf water potential, showing a better vertical growth rate, higher fine root dry weight and higher root to shoot biomass ratio [ 8 ]. Rootstocks G202, G814 and Marubakaido/M9 interstock also improved the tolerance of ‘Maxi Gala’ grafted tree when exposed to short-term waterlogging by producing new adventitious roots [ 16 ].…”

The growth and productivity of several apple rootstocks have been evaluated in various previous studies. However, limited information is available on their tolerance to osmotic stress. In the present study, the physiological and molecular responses as well as abscisic acid (ABA) levels were assessed in six apple rootstocks (M26, V3, G41, G935, B9 and B118) osmotically stressed with polyethylene glycol (PEG, 30%) application under greenhouse conditions. Our results showed that V3, G41, G935 and B9 had higher relative water content (RWC), and lower electrolyte leakage (EL) under stress conditions compared to M26 and B118. Additionally, water use efficiency (WUE) was higher in V3, G41 and B9 than M26, which might be partially due to the lower transpiration rate in these tolerant rootstocks. V3, G41 and B9 rootstocks also displayed high endogenous ABA levels which was combined with a reduction in stomatal conductance and decreased water loss. At the transcriptional level, genes involved in ABA-dependent and ABA-independent pathways, e.g., SnRK, DREB, ERD and MYC2, showed higher expression in V3, G41, G935 and B9 rootstocks compared to M26 in response to stress. In contrast, WRKY29 was down-regulated in response to stress in the tolerant rootstocks, and its expression was negatively correlated with ABA content and stomatal closure. Overall, the findings of this study showed that B9, V3 and G41 displayed better osmotic stress tolerance followed by G935 then M26 and B118 rootstocks.
