Currently, limited information is available on the molecular basis of the biosynthesis of essential oil in the Monarda citriodora plant. Given the pivotal role of the MEP pathway in the biosynthesis of monoterpenes, in the present study, DXS genes have been functionally characterized from M. citriodora, for the first time. The CDS corresponding to four McDXS genes (1–4) were cloned, and their deduced proteins displayed distinct phylogenetic positioning. Using a bacterial complementation test, we demonstrated that all four McDXS genes encode functional DXS proteins. Based on the results obtained from phylogenetic analysis, tissue-specific expression analysis, and accumulation of monoterpenes, McDXS2 was identified as the candidate gene involved in the biosynthesis of monoterpenes of essential oil in M. citriodora. Transient overexpression and silencing of McDXS2 significantly modified the content of volatile monoterpenes in M. citriodora. Constitutive expression of McDXS2 in Nicotiana tabacum resulted in increased biosynthesis of specialized diterpenoids. Further, the exogenous treatment of MeJA, ABA, and GA3 modulated the expression of McDXS2, and the content of the components of essential oil in M. citriodora. McDXS2 promoter activity was primarily restricted to the glandular trichomes of M. citriodora. The present work demonstrates that McDXS2 is primarily involved in the specialized terpenoid biosynthesis in M. citriodora.

Sparingly-soluble CaCO<inf>3</inf> promotes plant growth and arsenic accumulation in As-hyperaccumulator Pteris vittata: Oxidative stress and gene expression in As metabolisms

Being a lithophytic plant and arsenic-hyperaccumulator, Pteris vittata can efficiently utilize sparingly-soluble CaCO3, which enhances its arsenic (As) uptake and plant growth with the underlying mechanisms being unclear. Here, after growing P. vittata for 14 days under hydroponics containing 50 μM As and 8.0 mM CaCO3 or 0.8 mM CaCl2, the plant biomass, Ca, As and malondialdehyde (MDA) contents and As-metabolizing gene expressions in P. vittata were determined. Compared to CaCl2 control, CaCO3 increased plant biomass by 44−57 % to 2.4−3.9 g plant−1. Consistent with its better growth, P. vittata effectively solubilized CaCO3, with Ca being increased from 42−57 to 356−369 μM in the growth media, resulting in 38−76 % greater Ca uptake in the roots. Due to its continued Ca supply, CaCO3+As treatment enhanced the As content in P. vittata fronds by 39 % to 1460 mg kg−1 compared to the CaCl2+As control, with MDA being decreased by 16 %. The increased As accumulation was probably attributed to 1.3−1.6 fold upregulation of phosphate transporters PvPht1;3/1;4 for As uptake in P. vittata roots, and 1.4-fold upregulation of arsenite antiporters PvACR3;2/3;3 for As translocation to and sequestration in P. vittata fronds. Overall, the efficient CaCO3 utilization and its enhanced As accumulation in P. vittata shed light on its potential application in phytoremediation of As-contaminated soils.
IPPI, the core enzyme in C<inf>5</inf>-unit metabolism, regulates terpenoid biosynthesis in Artemisia annua

In plants, isopentenyl diphosphate isomerase (IPPI) plays a key role in regulating terpenoid biosynthesis by reversibly converting IPP and DMADP, two universal C5 units derived from the plastidial MEP and cytoplasmic MVA pathways. However, the regulatory mechanisms of IPPIs across cellular compartments remain poorly understood. Artemisia annua, a medicinal plant renowned for its high yield of terpenoids, particularly the antimalarial drug artemisinin, serves as an excellent model for studying IPPIs function. In this study, we identified a novel dual-localized IPPI (AaIPPI2) in A. annua alongside the previously characterized plastid-localized AaIPPI1, and explored their contributions to terpenoid biosynthesis. Our results showed that AaIPPI2, primarily localized in cytoplasm, exhibited significantly lower catalytic activity toward IPP compared to AaIPPI1. Overexpression of AaIPPIs in their respective compartments enhanced the production of monoterpenes, particularly camphene and camphor. Interestingly, although artemisinin levels increased to 1.5 mg/g FW, the overall sesquiterpene synthesis did not significantly rise. This suggested that adequate levels of AaIPPI2 and its IPP substrates were manufactured in cytoplasm to compensate for its lower activity, thereby supporting sesquiterpene biosynthesis. This mechanism also facilitated the accumulation of cytoplasmic IPP and its flux into plastids for monoterpene biosynthesis. Conversely, monoterpene biosynthesis was limited by the availability of AaIPPI1 and IPP substrates. Additionally, interference with AaIPPI1 expression impaired terpenoid synthesis in both compartments, indicating that IPP formation and its normal flow between cytoplasm and plastids were disrupted. These findings enhance our understanding of terpenoid synthesis regulation in A. annua and suggest strategies for optimizing terpenoid production in plants.

Endophytic fungi are crucial for enhancing plant growth and stress tolerance. Phomopsis liquidambaris B3, a broad-spectrum endophytic fungus, significantly improves plant nitrogen uptake and growth under nitrogen-limited conditions. In this study, we identified a small secreted protein, PlSSP, which localizes to the cytoplasmic matrix of host cells and modulates plant immune responses. Using proteomic and transcriptomic approaches, we found that PlSSP upregulates key defense-related genes, including members of the PR and WRKY families, as well as genes involved in reactive oxygen species scavenging and nitrogen assimilation. Structural analysis revealed PlSSP's secondary and thermal stability features, which likely contribute to its functional interaction with host cellular components. Functional analyses demonstrated that PlSSP expression correlates with increased fungal colonization and rice biomass accumulation under nitrogen-starved conditions. These results advance our understanding of how P. liquidambaris promotes plant resilience and nutrient uptake, providing insights with potential applications in sustainable agriculture.

Sugarcane (Saccharum spp.) is a globally important crop, and strategies to minimize the negative impacts of its cultivation and enhance its development are highly relevant. Plant growth-promoting bacteria (PGPB) can sustainably foster plant growth in agricultural systems and mitigate adverse effects of stress on plants. This is the first study to investigate the combined use of Azospirillum brasilense (Ab) and Nitrospirillum amazonense (Na), two microorganisms widely applied in agricultural systems, aiming to elucidate their effects on the nutritional status, biochemical responses, and productive parameters of sugarcane. Greenhouse experiments were conducted under controlled water and temperature conditions with four treatments: application of Ab, Na, or Ab + Na (Mix) or no PGPB application (control). Sugarcane was cultivated until the middle of the rapid growth stage. To validate the results, the greenhouse trials were replicated under field conditions at two sites (Maracaí-SP and Pradópolis-SP). The results showed that the inoculation of sugarcane with plant growth-promoting bacteria (PGPB), particularly Ab and Mix, enhanced nutritional aspects, especially N content. These increases were significant under greenhouse (p ≤ 0.05) and field conditions (p ≤ 0.10). Additionally, inoculation reduced oxidative stress and improved photosynthetic parameters, such as net photosynthetic rate, water use efficiency, and carboxylation efficiency. These cascading effects contributed to significant gains in crop productivity, with an average increase in stalk yield of 10.9 % for Ab and 12.2 % for Mix across both environments. Similarly, there was an increase in sugar yield per hectare, with gains of 13.3 % for Ab and 13.7 % for Mix compared to the control. These findings highlight the potential of PGPB as a sustainable strategy to enhance crop productivity and resilience, contributing to environmentally balanced agricultural systems. Although the benefits of PGPB were evident, differences between Ab and Mix were not pronounced. Therefore, additional studies are needed to explore the potential of these combinations under adverse conditions, when their effects could be more pronounced.
