CaNAC76 enhances lignin content and cold resistance in pepper by regulating CaCAD1.

Low temperature restricts the growth, development, and yield of peppers, significantly limiting the development of the pepper industry. NAC (NAM, ATAF1/2, and CUC2) transcription factors (TFs) are implicated in plant responses to cold stress, but their specific mechanisms in peppers are unclear. In this study, we isolated a cold-induced NAC transcription factor, CaNAC76, from pepper (Capsicum annuum L.

ERD14 regulation by the HY5- or HY5-MED2 module mediates the cold signal transduction of asparagus bean.

Cold stress affects the growth, development, and yield of asparagus bean (Vigna unguiculata subsp. sesquipedalis). Mediator (MED) complex subunits regulate the cold tolerance of asparagus bean, but the underlying regulatory mechanisms remain unclear.

Functional characterization of CaSOC1 at low temperatures and its role in low-temperature escape.

Environmental factors such as light and temperature tightly regulate plant flowering time. Under stressful conditions, plants inhibit vegetative growth and accelerate flowering as an emergency response. This adaptive mechanism benefits the survival of species and enhances their reproductive success.

CaMYB80 enhances the cold tolerance of pepper by directly targeting .

Cold temperatures negatively impact crop yield and quality, posing significant limitations to the advancement of the vegetable industry. MYB transcription factors are pivotal in enhancing plant resilience against various abiotic stresses, including low-temperature stress. Pepper ( L.

Molecular regulation by HS of antioxidant and glucose metabolism in cold-sensitive Capsicum.

Background: Cold is an important environmental limiting factor affecting plant yield and quality. Capsicum (chili pepper), a tropical and subtropical vegetable crop, is extremely sensitive to cold. Although HS is an important signaling regulator in the responses of plant growth and development to abiotic stress, few studies have examined its effects on cold-sensitive capsicum varieties.

Physiological and transcriptome analysis of changes in endogenous hormone and sugar content during the formation of tender asparagus stems.

Asparagus is a nutritionally dense stem vegetable whose growth and development are correlated with its quality and yield. To investigate the dynamic changes and underlying mechanisms during the elongation and growth process of asparagus stems, we documented the growth pattern of asparagus and selected stem segments from four consecutive elongation stages using physiological and transcriptome analyses. Notably, the growth rate of asparagus accelerated at a length of 25 cm.

Proanthocyanidins delay the senescence of young asparagus stems by regulating antioxidant capacity and synthesis of phytochemicals.

Asparagus, characterized by its high metabolic rate, is susceptible to quality degradation. Proanthocyanidins have antioxidant, antibacterial, antiviral, and other biological functions and can inhibit the production of reactive oxygen species in plants. To enhance the shelf life of asparagus, we investigated the impact of various concentrations of proanthocyanidins on its cold storage and preservation.

Comparative phylogenetic analysis of the mediator complex subunit in asparagus bean (Vigna unguiculata ssp. sesquipedialis) and its expression profile under cold stress.

Background: The mediator complex subunits (MED) constitutes a multiprotein complex, with each subunit intricately involved in crucial aspects of plant growth, development, and responses to stress. Nevertheless, scant reports pertain to the VunMED gene within the context of asparagus bean (Vigna unguiculata ssp. sesquipedialis).

Molecular Regulatory Mechanism of Exogenous Hydrogen Sulfide in Alleviating Low-Temperature Stress in Pepper Seedlings.

Pepper ( L.) is sensitive to low temperatures, with low-temperature stress affecting its plant growth, yield, and quality. In this study, we analyzed the effects of exogenous hydrogen sulfide (HS) on pepper seedlings subjected to low-temperature stress.

NO and GSH Alleviate the Inhibition of Low-Temperature Stress on Cowpea Seedlings.

Low-temperature stress in early spring seriously affects the growth and development of cowpea seedlings. To study the alleviative effect of the exogenous substances nitric oxide (NO) and glutathione (GSH) on cowpea ( (Linn.) ) seedlings under 8 °C low-temperature stress, 200 μmol·L NO and 5 mmol·L GSH were sprayed on cowpea seedlings whose second true leaf was about to unfold to enhance the tolerance of cowpea seedlings to low temperature.

, a Spermidine Synthase Gene from Pepper ( L.), Plays an Important Role in Response to Cold Stress.

Spermidine synthase (SPDS) is a key enzyme in the polyamine anabolic pathway. genes help regulate plant response to environmental stresses, but their roles in pepper remain unclear. In this study, we identified and cloned a SPDS gene from pepper ( L.

Genome and pan-genome assembly of asparagus bean ( ssp. ) reveal the genetic basis of cold adaptation.

Asparagus bean ( ssp. ) is an important cowpea subspecies. We assembled the genomes of Ningjiang 3 (NJ, 550.

Genome-Wide Identification of Polyamine Oxidase (PAO) Family Genes: Roles of and in the Cold Tolerance of Pepper ( L.).

Polyamine oxidases (PAOs), which are flavin adenine dinucleotide-dependent enzymes, catalyze polyamine (PA) catabolism, producing hydrogen peroxide (HO). Several PAO family members have been identified in plants, but their expression in pepper plants remains unclear. Here, six PAO genes were identified in the 'Zunla-1' pepper genome (named - according to their chromosomal positions).

Transcriptome Profiling Reveals the Effects of Nitric Oxide on the Growth and Physiological Characteristics of Watermelon under Aluminum Stress.

Excessive aluminum ions (Al) in acidic soil can have a toxic effect on watermelons, restricting plant growth and reducing yield and quality. In this study, we found that exogenous application of nitric oxide (NO) could increase the photochemical efficiency of watermelon leaves under aluminum stress by promoting closure of leaf stomata, reducing malondialdehyde and superoxide anion in leaves, and increasing POD and CAT activity. These findings showed that the exogenous application of NO improved the ability of watermelon to withstand aluminum stress.
