The global food production for the worldwide population mainly depends on huge contributions of agricultural sector. cultivated crops foods need various elements or nutrients to complete their growth, and these are indirectly consumed by humans. During this production, several environmental constraints stresses may cause losses in production. These obstacles include abiotic biotic stresses, which have already been studied both individual combined cases. However, there very few studies multiple stresses. On basis myriad benefits nanotechnology agriculture, nanofertilizers (or nanonutrients) become promising tools sustainability. Nanofertilizers also proper solution overcoming health problems that can result from conventional fertilizers. role has increased, especially under different individual, combined, most commonly nature; however, still needed stress levels. play a crucial supporting plants improving plant yield, quantitatively qualitatively. Similar other biological issues, many open-ended questions require further investigation: Is right time era agriculture? Will be dominant source modern Are nanofertilizers, particularly synthesized ones, magic sustainable What expected damages plants?

The MYB transcription factors (TFs) are evolving as critical role in the regulation of phenylpropanoid and tanshinones biosynthetic pathway. TFs relate to a very important gene family, which involved primary secondary metabolisms, terpenoids, bioactive compounds, plant defense against various stresses cell morphology. R2R3 contained conserved N-terminal domain, but domain at C-terminal sorts them different regarding their structures functions. suppressors generally possess particular repressive motifs, such pdLNLD/ELxiG/S TLLLFR, contribute suppression through diversity complex regulatory mechanisms. A novel flower specific "NF/YWSV/MEDF/LW" motif has great potential understand mechanisms development. In current review, we summarize recent advanced progress on regulation, posttranscriptional, microRNA, propose directions future prospective research. We further suggest there should be more focus investigation for microalgae, heterologous protein expression system perspectives.

ABI5 promotes heat stress-induced chlorophyll degradation by modulating the stability of MYB44 in cucumber

Horticulture Research, Год журнала: 2023, Номер 10(6)

Опубликована: Май 4, 2023

Abstract The yellowing of leaves caused by the decomposition chlorophyll (Chl) is a characteristic event during senescence, which can be induced various environmental stresses. However, molecular mechanisms high temperature-induced Chl degradation in horticultural plants remain poorly understood. Here, we found that heat stress and expression ABI5 MYB44 cucumber. Silencing compromised stress-induced degradation, transcription pheophytinase (PPH) pheophorbide oxygenase (PAO), two key genes catabolic pathway, but silencing exhibited opposite results. Furthermore, interacted with vitro vivo. positively regulated through pathways. directly bound to PPH PAO promoters promote their expression, leading accelerating degradation. On other hand, interaction between reduced binding led ubiquitination-depended protein MYB44, thereby alleviating inhibitory effect on PAO. Taken together, our findings propose new regulatory network for regulating

Transcription factor PgCDF2 enhances heat tolerance of Physalis grisea by activating heat shock transcription factors PgHSFA1 and PgHSFB3

The Plant Journal, Год журнала: 2025, Номер 121(5)

High temperature influence flower bud differentiation in Physalis grisea, resulting the production of deformed fruits and affects fruit yield quality. However, molecular mechanisms underlying response P. grisea to heat stress (HS) remain unclear. In this study, HS treatment dynamic transcriptome analysis identified PgCDF2-PgHSFA1/PgHSFB3 transcriptional regulatory module as playing a key role HS. Gene Ontology (GO) enrichment analysis, regulation prediction, weighted correlation network (WGCNA) (HS)-responsive data three genes, PgCDF2, PgHSFA1 PgHSFB3, components grisea. The expression levels PgHSFA1, PgHSFB3 were up-regulated following exposure Silencing resulted reduced tolerance altered reactive oxygen species Dual-luciferase assay Electrophoretic Mobility Shift Assay (EMSA) results indicate that PgCDF2 binds promoters activate their expression. inhibited also summary, under HS, enhances by activating PgHSFB3. This study clarifies providing theoretical basis for more in-depth response.

The CsMYB44‐csi‐miR0008‐CsCER1 module regulates cuticular wax biosynthesis and drought tolerance in citrus

New Phytologist, Год журнала: 2025, Номер unknown

Опубликована: Март 27, 2025

Cuticular wax covering aboveground organs serves as the first line of defense shielding plants from nonstomatal water loss and diverse environmental stresses. While there have been several wax-related genes identified, molecular mechanisms responsible for control biosynthesis remain poorly understood in citrus, particularly at posttranscriptional level. Here, we demonstrated that CsMYB44-csi-miR0008-CsCER1 module is regulating drought tolerance citrus through its cuticular biosynthesis. In this study, microRNA (miRNA) sequencing analyses 'Newhall' navel oranges wax-deficient 'Ganqi 3' mutant variety led to identification a novel biosynthesis-related miRNA, csi-miR0008. csi-miR0008 suppresses expression CsCER1, an aldehyde decarbonylase-encoding gene associated with n-alkane The leaves csi-miR0008-silencing CsCER1-overexpressing exhibited increases total levels, pronounced contributing enhanced tolerance. csi-miR0008-overexpressing CsCER1-silencing opposite phenotypes. CsMYB44 was confirmed promote accumulation by directly inhibiting Taken together, our study offers new insight into biosynthesis, while also providing foundation breeding varieties exhibiting

Tolerance to combined drought and heat stress in edamame is associated with enhanced antioxidative responses and cell wall modifications

Physiologia Plantarum, Год журнала: 2025, Номер 177(2)

Опубликована: Март 1, 2025

Drought and heat stress often co-occur in nature, their combined effects are a major driver of crop losses, causing more severe damage to plant metabolism than when they occur individually. This study investigates the responses three edamame cultivars (AGS429, UVE14, UVE17) drought (DH) stress, with emphasis on reactive oxygen species (ROS), antioxidative mechanisms cell wall modifications. Malondialdehyde (MDA), electrolyte leakage (EL), hydrogen peroxide (H2O2) were used measure oxidative membrane damage. The non-enzymatic (ascorbic acid, AsA) enzymatic (superoxide dismutase, ascorbate peroxidase (APX), guaiacol peroxidase, glutathione reductase) antioxidant determined spectrophotometrically. Cell biomass composition (cellulose, hemicellulose, lignin, phenols) was using Fourier transform Infrared Spectroscopy spectrophotometry. Ascorbate activity AsA content DH-stressed AGS429 at flowering strongly correlated reduced lipid peroxidation (r2 = -0.97 - 0.98). Cultivar UVE14 accumulated high under DH both growth stages, which, turn, positively associated total phenolic 0.97), APX activity, holocellulose, suggesting enhanced ROS-dependent polymerisation. On contrary, poor ROS quenching UVE17 led MDA accumulation (p ≤ 0.05), leading EL cellulose synthesis pod-filling -0.88). Therefore, physio-biochemical level, showed tolerance through modifications, while susceptible. Identifying key biochemical traits linked offers novel insights for breeding resilient cultivars.
