Drought stress is known as a major yield-limiting factor in crop production that threatens food security worldwide. Arbuscular mycorrhizal fungi (AMF) and titanium dioxide (TiO2) have shown to alleviate the effects of drought stress on plants, but information regarding their co-addition to minimize the effects of drought stress on plants is scant. Here, a two-year field experiment was conducted in 2019 and 2020 to evaluate the influence of different irrigation regimes and fertilizer sources on the EO quantity and quality of sage (Salvia officinalis L.). The experiment was laid out as a split plot arranged in a randomized complete block design with three replicates. The irrigation treatments were 25, 50, and 75% maximum allowable depletion (MAD) percentage of the soil available water as non-stress (MAD25), moderate (MAD50), and severe (MAD75) water stress, respectively. Subplots were four fertilizer sources including no-fertilizer control, TiO2 nanoparticles (100 mg L−1), AMF inoculation, and co-addition of TiO2 and AMF (TiO2 + AMF). Moderate and severe drought stress decreased sage dry matter yield (DMY) by 30 and 65%, respectively. In contrast, application of TiO2 + AMF increased DMY and water use efficiency (WUE) by 35 and 35%, respectively, compared to the unfertilized treatment. The highest EO content (1.483%), yield (2.52 g m−2), and cis-thujone (35.84%, main EO constituent of sage) was obtained in MAD50 fertilized with TiO2 + AMF. In addition, the net income index increased by 44, 47, and 76% with application of TiO2 nanoparticles, AMF, and co-addition of TiO2 +AMF, respectively. Overall, the integrative application of the biofertilizer and nanoparticles (TiO2 + AMF) can be recommended as a sustainable strategy for increasing net income and improving EO productivity and quality of sage plants in drought stress conditions. Future policy discussions should focus on incentivizing growers for replacing synthetic fertilizers with proven nano and biofertilizers to reduce environmental footprints and enhance the sustainability of sage production, especially in drought conditions.

The effects of the amount and timing of regulated deficit drip irrigation under plastic film on potato (‘Qingshu 168’) growth, photosynthesis, yield, water use efficiency, and quality were examined from 2017 to 2019 in cold and arid northwestern China. A two-factor randomized design was used with two levels of regulated deficit irrigation (mild, moderate) applied in four stages of potato growth (seedling, tuber initiation, tuber bulking, starch accumulation). Growth and photosynthetic parameters were determined in each growth stage, and yield and quality were measured after harvest. The net photosynthetic rate, stomatal conductance, and transpiration rate decreased significantly under water deficit in the tuber formation and starch accumulation stages, and the decreases were greater with moderate than mild water deficit. Although water deficit reduced potato yields, potato subjected to mild water deficit in the seedling stage had the highest yield at 43,961.91 kg·ha−1, followed by those subjected to mild water deficit in the starch accumulation stage at 42,262.25 kg·ha−1, which were decreases of only 4.50% and 8.19%, respectively, compared with potato under full irrigation. The highest water use efficiency was in potatoes subjected to mild water deficit in the seedling stage (8.67 kg·m−3), with the second highest in those subjected to moderate water deficit in the seedling stage (8.28 kg·m−3), which were significant improvements by 10.87% and 5.84%, respectively, compared with full irrigation. The highest overall quality was in potatoes subjected to mild and moderate water deficit in the seedling stage. The starch content in potatoes with mild water deficit in the seedling stage increased by 3.34% compared with that under full irrigation. In addition, the protein and vitamin C contents in potatoes under moderate water deficit increased significantly by 0.77% and 21.59%, respectively, compared with the contents under full irrigation. Principal component analysis identified mild water stress in the seedling stage as the optimum regulated deficit irrigation regime for potato. Thus, the relative soil water content should be maintained at 55% to 65% of field capacity in the seedling stage but at 65% to 75% in the other growth stages. The results of this study provide theoretical and technical references for efficient water-saving cultivation and industrialization of potato in cold and arid northwestern China.

“…Traits particularly linked to its productivity enhancement are adaptations to both biotic and abiotic stresses, including cold in a temperate environment, drought, heat, as well as salinity (Taleghani et al ., 2022; Zou et al ., 2020). Drought adaptation refers to a process in which the sugar beet develops fundamental resistance against drought challenges through biochemical and physiological alterations (Alkahtani et al ., 2021; Li et al ., 2019). The drought response of sugar beet is definitively linked to the levels of BvHb2 and other proteinencoding genes (Gisbert et al ., 2020).…”

Drought is one of the most common abiotic constraints on the quality and productivity of crops on a global scale. Despite the rapidly updating information on circRNAs (circular RNAs), their roles in the anti-drought regulation of sugar beet are least understood. As a newly recognized class of non-coding RNAs, circRNAs exert crucial effects on miRNA (microRNA) functionality, as well as on transcriptional regulation. To clarify the mechanism of how circRNAs of sugar beet respond to drought stress, deep sequencing was employed to characterize these circRNAs in a genome-wide manner under drought treatment. Our results identify a total of 17 differentially expressed circRNAs. As revealed by the Kyoto Encyclopedia of Genes and Genomes and Gene Ontology outcomes, circRNAs were found capable and involved in drought-responsive events. Utilizing the target genes exhibiting direct/indirect associations with drought resistance, we established a circRNA–miRNA–mRNA meshwork based on the circRNAs that were expressed differentially. The probable sponge functions of novel_circ_0000442 and novel_circ_0000443 were exerted by targeting ath-miR157d. This helped regulate the expression of relevant target genes, including BVRB_1 g004570, BVRB_1 g005450, and BVRB_1 g005790, that were involved in drought response. Apart from offering novel understandings of anti-drought mechanisms, our findings lay a basis for probing deeper into the intricate regulatory networks of sugar beet genes.
