“…The predicted interaction network for papaya demonstrates that CpTIP5;1 and the other three members of CpNIPs interacted with BOR4 (Figure 5), indicating that CpAQPs may play an indirect role in the process of boron uptake and accumulation. In sugar beet, NIPs have been reported to play important roles in silicon uptake and growth [66]. These studies reveal that NIPs play a role in the absorption, transport, and accumulation of arsenic, boron, and silicon.…”

Aquaporins (AQPs) are mainly responsible for the transportation of water and other small molecules such as CO2 and H2O2, and they perform diverse functions in plant growth, in development, and under stress conditions. They are also active participants in cell signal transduction in plants. However, little is known about AQP diversity, biological functions, and protein characteristics in papaya. To better understand the structure and function of CpAQPs in papaya, a total of 29 CpAQPs were identified and classified into five subfamilies. Analysis of gene structure and conserved motifs revealed that CpAQPs exhibited a degree of conservation, with some differentiation among subfamilies. The predicted interaction network showed that the PIP subfamily had the strongest protein interactions within the subfamily, while the SIP subfamily showed extensive interaction with members of the PIP, TIP, NIP, and XIP subfamilies. Furthermore, the analysis of CpAQPs’ promoters revealed a large number of cis-elements participating in light, hormone, and stress responses. CpAQPs exhibited different expression patterns in various tissues and under different stress conditions. Collectively, these results provided a foundation for further functional investigations of CpAQPs in ripening, as well as leaf, flower, fruit, and seed development. They also shed light on the potential roles of CpAQP genes in response to environmental factors, offering valuable insights into their biological functions in papaya.

“…SIPs are associated with intracellular membranes, especially the endoplasmic reticulum, and play an irreplaceable role in facilitating cellular water transport [42]. The previous study on sugar beets showed that SIP1;2 and SIP2;1 were paired with NIPs in the transport of boron and nitrite through gene interaction analysis [43]. The present study showed that the four strengths of exogenous EE-GRSP treatments significantly down-regulated the relative expression of CsNIP1;1, CsNIP5;1, and CsSIP1;2; meanwhile, the relative expression of both CsNIP1;1 and CsSIP1;2 showed significant or highly significant and negative correlations with the plant growth indexes, including the plant height, stem diameter, and fresh weight of tea seedlings, suggesting a potential pairing relationship between these SIPs and NIPs for transporting small molecules and minerals.…”

Glomalin, a glycoprotein secreted by arbuscular mycorrhizal fungi (AMFs), exhibits multiple beneficial functions in regard to plant growth. However, the roles and regulatory mechanisms of exogenous easily extractable glomalin-related soil protein (EE-GRSP) in water and their effects on the quality of tea plants (Camellia sinensis (L.) O. Ktze.) remain unclear. The present study aimed to investigate the effects of a quarter-strength exogenous EE-GRSP solution (1/4 EE-GRSP), half-strength exogenous EE-GRSP solution (1/2 EE-GRSP), three-quarter-strength exogenous EE-GRSP solution (3/4 EE-GRSP), and full-strength exogenous EE-GRSP solution (full EE-GRSP) on plant growth, the root system architecture, leaf water status, and the tea quality of tea seedlings, along with examining the changes in the relative expression of water channel proteins (AQPs) in tea plants. The results indicated that exogenous EE-GRSP of different strengths had different effects on both the growth performance (height, leaf numbers, and biomass) and root architecture parameters of tea seedlings, and the best positive effects on plant growth and the root architecture appeared under the three-quarter-strength exogenous EE-GRSP treatment. Similarly, the exogenous EE-GRSP application also differently affected tea quality indicators, in which only the quarter- and half-strength exogenous EE-GRSP solutions significantly increased most of the indicators, including carbohydrates, tea polyphenols, total amino acids, catechins, and flavonoids. Moreover, the half- and three-quarter-strength exogenous EE-GRSP treatments significantly increased the leaf relative water content (LRWC), but all of the exogenous EE-GRSP treatments significantly decreased the leaf water potential (LWP). Furthermore, the expression of AQP genes in the root system of tea plants was related to the strength of the exogenous EE-GRSP treatments, and different genes were significantly up-regulated or down-regulated under the treatment of exogenous EE-GRSP at different strengths. Moreover, the correlation analysis showed that most of the relative expression of AQPs was significantly and positively correlated with tea plant growth, the root architecture, and the leaf relative water content, but negatively correlated with tea quality indicators; however, the expression of CsNIPs and CsSIPs was markedly and negatively correlated with plant growth performance. Therefore, we speculated that the application of exogenous EE-GRSP could facilitate plant growth and improve the quality indirectly by regulating the expression of root AQPs, thus ameliorating the water uptake and nutrient accumulation in tea plants.

“…Mineral nutrition-mediated abiotic stress alleviation in plants is one of the promising approaches [3,4]. Silicon (Si) is a beneficial element that efficiently mitigates multiple abiotic stresses and improves growth in plants [5][6][7][8][9]. Plant seed soaking, foliar spray, and root treatment with exogenous supplementation of Si mitigate the negative effects of frost-induced damage in plants [10].…”

“…Si shows interaction with other essential and beneficial elements. For instance, exogenous Si enhances endogenous Si [6], declines the activity of Ca 2+ [12], enhances the regulation of magnesium (Mg) and sulfur (S) [13]. These interactions lead to enhance plant growth, fitness, and stress adaptation in plants.…”

“…NIP genes are located in the plasma membrane (PM), endoplasmic reticulum, and vacuoles, and are reported to be expressed in the entire organelle or cell surface [15]. NIP transporters including NIP2, NIP5;1, and NIP6;1 promote Si uptake in plants [6]. These transporters show higher permeability to low organic molecules (LOM), thereby transporting Si and other beneficial or toxic metals [6].…”

Cold stress (CS) impact on crops is one of the critical constraints for sustainable and smart agricultural production. CS adversely affects plants leading to growth retardation, necrosis, chlorosis, and significant yield loss. The objective of this study was to explore the mechanistic basis of silicon (Si) in enhancing CS tolerance in alfalfa plants. The fluorescence staining indicated that Si-reduced the intensity of CS-induced superoxide radical (O2•–) and hydrogen peroxide (H2O2) generation in plants that improved plant photosynthesis, cellular integrity, and alfalfa biomass production under CS. The exogenous supplementation of Si significantly restored the endogenous Si status accompanied by the upregulation of NIP (nodulin 26-like intrinsic protein) genes NIP2, NIP5;1, and NIP6;1 in alfalfa. The elemental concentration analysis revealed that exogenous silicon (E-Si) triggers the increase of calcium (Ca), magnesium (Mg), and sulfur (S) in plants subjected to Si-supplementation compared to the plants cultivated without Si under CS. The application of Si significantly increased the activity of antioxidant enzymes including superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), and glutathione reductase (GR). Furthermore, Si significantly enhanced the expression of CS-responsive candidate genes including ICE1, CBF1/DREB1C, CBF2/DREB1B, CBF3/DREB1A, COR15A, COR47, and KIN1 in alfalfa. These findings together provide mechanistic insights into Si-involving CS tolerance in alfalfa. This eco-friendly SC management strategy using Si treatment can be useful to plant breeders and farmers for developing CS-resilient smart alfalfa production through breeding program.
