“…Furthermore, Xu et al (2021) determined the function of the aquaporin gene MaPIP1;1 and confirmed that overexpression led to multiple stress tolerance in bananas, including drought and cold. Recently, Lopez-Zaplana et al (2022) elucidated that aquaporins (PIP2;1, PIP2;5 and PIP2;6) decreases with the magnitude of different abiotic stresses in melon.…”

Low-temperature stress (LTS) drastically affects vegetative and reproductive growth in fruit crops leading to a gross reduction in the yield and loss in product quality. Among the fruit crops, temperate fruits, during the period of evolution, have developed the mechanism of tolerance, i.e., adaptive capability to chilling and freezing when exposed to LTS. However, tropical and sub-tropical fruit crops are most vulnerable to LTS. As a result, fruit crops respond to LTS by inducing the expression of LTS related genes, which is for climatic acclimatization. The activation of the stress-responsive gene leads to changes in physiological and biochemical mechanisms such as photosynthesis, chlorophyll biosynthesis, respiration, membrane composition changes, alteration in protein synthesis, increased antioxidant activity, altered levels of metabolites, and signaling pathways that enhance their tolerance/resistance and alleviate the damage caused due to LTS and chilling injury. The gene induction mechanism has been investigated extensively in the model crop Arabidopsis and several winter kinds of cereal. The ICE1 (inducer of C-repeat binding factor expression 1) and the CBF (C-repeat binding factor) transcriptional cascade are involved in transcriptional control. The functions of various CBFs and aquaporin genes were well studied in crop plants and their role in multiple stresses including cold stresses is deciphered. In addition, tissue nutrients and plant growth regulators like ABA, ethylene, jasmonic acid etc., also play a significant role in alleviating the LTS and chilling injury in fruit crops. However, these physiological, biochemical and molecular understanding of LTS tolerance/resistance are restricted to few of the temperate and tropical fruit crops. Therefore, a better understanding of cold tolerance’s underlying physio-biochemical and molecular components in fruit crops is required under open and simulated LTS. The understanding of LTS tolerance/resistance mechanism will lay the foundation for tailoring the novel fruit genotypes for successful crop production under erratic weather conditions.

“…In their role against drought and salinity stresses, it has been suggested that the Aquaporins regulated changes in the root, stem and leaf hydraulic conductivity, plant water usage in response to stress (Vandeleur et al, 2009;Vandeleur et al, 2014;Sade and Moshelion, 2017). Similarly, an observation where an up regulation of ClAQP was observed under salinity and drought stress and also during fruit development of the cultivated watermelon and cucumis melo (Wang et al, 2016;Kusvuran et al, 2021;Lopez-Zaplana et al, 2022) suggesting the involvement of the aquaporins in tolerance mechanisms of the citrullus species. Another important protectant that has been documented to play an important role in drought and salinity stress is the trehalose that is suggested to play an important role in regulation of stomatal aperture, regulation of plant water use, osmolyte protectants and acting as an energy source thus aiding the tolerance mechanisms of plants.…”

Climate change has escalated the effect of drought on crop production as it has negatively altered the environmental condition. Wild watermelon grows abundantly in the Kgalagadi desert even though the environment is characterized by minimal rainfall, high temperatures and intense sunshine during growing season. This area is also characterized by sandy soils with low water holding capacity, thus bringing about drought stress. Drought stress affects crop productivity through its effects on development and physiological functions as dictated by molecular responses. Not only one or two physiological process or genes are responsible for drought tolerance, but a combination of various factors do work together to aid crop tolerance mechanism. Various studies have shown that wild watermelon possess superior qualities that aid its survival in unfavorable conditions. These mechanisms include resilient root growth, timely stomatal closure, chlorophyll fluorescence quenching under water deficit as key physiological responses. At biochemical and molecular level, the crop responds through citrulline accumulation and expression of genes associated with drought tolerance in this species and other plants. Previous salinity stress studies involving other plants have identified citrulline accumulation and expression of some of these genes (chloroplast APX, Type-2 metallothionein), to be associated with tolerance. Emerging evidence indicates that the upstream of functional genes are the transcription factor that regulates drought and salinity stress responses as well as adaptation. In this review we discuss the drought tolerance mechanisms in watermelons and some of its common indicators to salinity at physiological, biochemical and molecular level.

“…[ 11 ]). In most of the plants for which the sequence of the aquaporins and functionality have been determined, PIPs are responsible for transporting water, H 2 O 2 and CO 2 [ 58 ], and TIPs are able to transport the same solutes as PIPs but also others such as N compounds (urea or ammonia) [ 59 ] and B [ 17 ]. In our results, we could observe a strong correlation between the Zn concentration and aquaporin PIP2 in all the organs (leaves, roots and bulbs).…”

“…Different types of regulations of plant aquaporins in response to salt stress have been reported. In general terms, the expression of the genes coding for PIPs and TIPs especially decrease in roots after a salinity treatment [ [13] , [14] , [15] , [16] , [17] ], as a defense mechanism to protect the cells from water loss due to osmotic stress [ 18 ], but it has also been reported that some isoforms were up-regulated [ [19] , [20] , [21] ] or not significantly altered by salt stress [ 22 , 23 ], depending on the NaCl concentration or plant tissue considered [ 24 ]. The increased expression or maintenance of specific isoforms from PIP and TIP subgroups has been considered as an adaptation mechanism to salt stress, influencing the osmotic balance via the regulation of the uptake of water and Na + exchange, to compensate against the reduced apoplastic pathway and the elevated osmotic potential [ 16 , 17 ], indicating their fundamental roles in salinity adjustment.…”
