“…When compared to animals, plants usually possess a higher number of AQPs, which have evolved into specific subfamilies that differ in solute specificity, subcellular localization, and molecular functions [ 12 ]. Plant AQPs are also diversified in terms of their expression profiling, with specific patterns in various tissues and under certain environmental conditions [ 13 , 15 ]. The higher number of AQPs in plants compared to animals is probably due to the higher frequency of whole-genome duplication events during plant evolution [ 18 ], and also possibly due to the plant physiology and sessile nature of life.…”

“…Genome-wide studies have identified two more subfamilies in non-vascular plant species, hybrid intrinsic proteins (HIPs) and GlpF-like intrinsic proteins (GIPs), suggesting the loss of these lineages in vascular plants [ 1 ]. Similarly, the loss of entire XIP subfamily has been observed in monocots and some of the dicots, like in many species belonging to Brassicaceae [ 13 , 15 ].…”

Aquaporins (AQPs) play a pivotal role in the cellular transport of water and many other small solutes, influencing many physiological and developmental processes in plants. In the present study, extensive bioinformatics analysis of AQPs was performed in Aquilegia coerulea L., a model species belonging to basal eudicots, with a particular focus on understanding the AQPs role in the developing petal nectar spur. A total of 29 AQPs were identified in Aquilegia, and their phylogenetic analysis performed with previously reported AQPs from rice, poplar and Arabidopsis depicted five distinct subfamilies of AQPs. Interestingly, comparative analysis revealed the loss of an uncharacterized intrinsic protein II (XIP-II) group in Aquilegia. The absence of the entire XIP subfamily has been reported in several previous studies, however, the loss of a single clade within the XIP family has not been characterized. Furthermore, protein structure analysis of AQPs was performed to understand pore diversity, which is helpful for the prediction of solute specificity. Similarly, an AQP AqcNIP2-1 was identified in Aquilegia, predicted as a silicon influx transporter based on the presence of features such as the G-S-G-R aromatic arginine selectivity filter, the spacing between asparagine-proline-alanine (NPA) motifs and pore morphology. RNA-seq analysis showed a high expression of tonoplast intrinsic proteins (TIPs) and plasma membrane intrinsic proteins (PIPs) in the developing petal spur. The results presented here will be helpful in understanding the AQP evolution in Aquilegia and their expression regulation, particularly during floral development.

“…Transporters are a class of transmembrane proteins facilitating the movement of selective molecules across plant membranes. They play a significant role in abiotic stress response as they control the traffic of ions and other biomolecules such as hormones and compatible solutes during stress to sustain vital cellular processes such as ion homeostasis, osmotic adjustment, signal transduction, and detoxification (Vishwakarma et al, 2019). Several transporter gene families ( Table 1) have been identified and characterized in B. napus such as aquaporins (Yuan et al, 2017), metal transporter genes [MTGs;Zhang et al (2018a)], ATP-binding cassette (ABC) transporter (Zhang et al, 2018b), sucrose transporters or sucrose carriers (SUT/ SUCs) and Sugars Will Eventually be Exported Transporters [SWEET;Jian et al (2016a)].…”

Engineering Multiple Abiotic Stress Tolerance in Canola, Brassica napus

Impacts of climate change like global warming, drought, flooding, and other extreme events are posing severe challenges to global crop production. Contribution of Brassica napus towards the oilseed industry makes it an essential component of international trade and agroeconomics. Consequences from increasing occurrences of multiple abiotic stresses on this crop are leading to agroeconomic losses making it vital to endow B. napus crop with an ability to survive and maintain yield when faced with simultaneous exposure to multiple abiotic stresses. For an improved understanding of the stress sensing machinery, there is a need for analyzing regulatory pathways of multiple stressresponsive genes and other regulatory elements such as non-coding RNAs. However, our understanding of these pathways and their interactions in B. napus is far from complete. This review outlines the current knowledge of stress-responsive genes and their role in imparting multiple stress tolerance in B. napus. Analysis of network cross-talk through omics data mining is now making it possible to unravel the underlying complexity required for stress sensing and signaling in plants. Novel biotechnological approaches such as transgene-free genome editing and utilization of nanoparticles as gene delivery tools are also discussed. These can contribute to providing solutions for developing climate change resilient B. napus varieties with reduced regulatory limitations. The potential ability of synthetic biology to engineer and modify networks through fine-tuning of stress regulatory elements for plant responses to stress adaption is also highlighted.

“…Compatible solutes are highly soluble organic compounds that could, under stress-induced cell desiccation, contribute to the cell osmotic adjustment without interfering with membrane integrity [13]. Sugars, polyols, and amino acids are non-toxic compounds that accumulate preferentially in the cytoplasm to maintain the osmotic balance and to protect the membrane structure to avoid membrane lysis and loss of semipermeability [36,37]. The sucrose concentration increased in leaves in response to increasing salinity stress, following a similar trend in all cultivars and populations regardless of their salinity tolerance.…”

Physiological and Biochemical Responses to Salt Stress of Alfalfa Populations Selected for Salinity Tolerance and Grown in Symbiosis with Salt-Tolerant Rhizobium

Alfalfa and its rhizobial symbiont are sensitive to salinity. We compared the physiological responses of alfalfa populations inoculated with a salt-tolerant rhizobium strain, exposed to five NaCl concentrations (0, 20, 40, 80, or 160 mM NaCl). Two initial cultivars, Halo (H-TS0) and Bridgeview (B-TS0), and two populations obtained after three cycles of recurrent selection for salt tolerance (H-TS3 and B-TS3) were compared. Biomass, relative water content, carbohydrates, and amino acids concentrations in leaves and nodules were measured. The higher yield of TS3-populations than initial cultivars under salt stress showed the effectiveness of our selection method to improve salinity tolerance. Higher relative root water content in TS3 populations suggests that root osmotic adjustment is one of the mechanisms of salt tolerance. Higher concentrations of sucrose, pinitol, and amino acid in leaves and nodules under salt stress contributed to the osmotic adjustment in alfalfa. Cultivars differed in their response to recurrent selection: under a 160 mM NaCl-stress, aromatic amino acids and branched-chain amino acids (BCAAs) increased in nodules of B-ST3 as compared with B-TS0, while these accumulations were not observed in H-TS3. BCAAs are known to control bacteroid development and their accumulation under severe stress could have contributed to the high nodulation of B-TS3.
