Potato is the most widely cultivated non-cereal crop in the world, and like any other crop, it is susceptible to yield losses because of various factors, including pathogen attacks. Among the various diseases of potato, late blight caused by the oomycete Phytophthora infestans is considered as the most devastating disease worldwide. In this study, transgenic potato plants overexpressing the D-galacturonic acid reductase (GalUR) gene with an enhanced level of cellular L-ascorbate (L-AsA) were challenged with Phytophthora infestans to determine the level of stress tolerance induced in those plants. With the onset of pathogen infection, necrotic lesions progressively expanded and became necrotic in the control plants. The transgenic potato lines with enhanced ascorbic acid showed reduced necrotic lesions. Hydrogen peroxide (H2O2) and malondialdehyde (MDA) levels were relatively lower in transgenic plants compared to the untransformed control (UT) plants. The mRNA expressions of pathogenesis-related (PR) genes, such as pathogenesis related 1 (PR1) and phenylalanine ammonia-lyase (PAL) were slightly higher in GalUR overexpressing transgenic lines as compared to the untransformed control plants. Pathogen infection also altered the mRNA expression of genes associated with gibberellic acid (GA) and abscisic acid (ABA) biosynthesis. Furthermore, the increase in various antioxidant enzymes was also observed in the gene expression analysis with the transgenic plants. The complete loss of the pathogen growth and disease occurrence was not observed in our study; however, the findings indicated that an increase in the level of cellular L-ascorbate in the transgenic potato leads to enhanced cellular antioxidants, PR genes and plant defense hormones, such as GA and ABA resulting in the reduction of the disease symptoms caused by the Phytophthora infestans.

“…rapa seedlings had significantly higher levels of hydroxybenzoic acid (604.43 g/g), hydroxycinnamic acid (720.78 g/g), and flavonol (1344.49 g/g) than untreated seedlings (390.68, 490.86, and 828.42 g/g, respectively [ 101 ]. Similarly, NiO NPs (250 and 500 mg/L) were shown to induce the expression of phenolic biosynthesis genes like PAP1, ANS, and PAL in Chinese cabbage seedlings [ 218 ]. NiO NPs (500 mg/L) treated Chinese cabbage seedlings exhibit notably elevated hydroxybenzoic acid (921.65 μg/g), hydroxycinnamic acid (890.38 μg/g), and flavonol (1228.18 μg/g) concentrations compared to untreated plants, at 659.41, 706.62, and 659.41 μg/g, respectively.…”

Nano-priming as emerging seed priming technology for sustainable agriculture—recent developments and future perspectives

Nano-priming is an innovative seed priming technology that helps to improve seed germination, seed growth, and yield by providing resistance to various stresses in plants. Nano-priming is a considerably more effective method compared to all other seed priming methods. The salient features of nanoparticles (NPs) in seed priming are to develop electron exchange and enhanced surface reaction capabilities associated with various components of plant cells and tissues. Nano-priming induces the formation of nanopores in shoot and helps in the uptake of water absorption, activates reactive oxygen species (ROS)/antioxidant mechanisms in seeds, and forms hydroxyl radicals to loosen the walls of the cells and acts as an inducer for rapid hydrolysis of starch. It also induces the expression of aquaporin genes that are involved in the intake of water and also mediates H2O2, or ROS, dispersed over biological membranes. Nano-priming induces starch degradation via the stimulation of amylase, which results in the stimulation of seed germination. Nano-priming induces a mild ROS that acts as a primary signaling cue for various signaling cascade events that participate in secondary metabolite production and stress tolerance. This review provides details on the possible mechanisms by which nano-priming induces breaking seed dormancy, promotion of seed germination, and their impact on primary and secondary metabolite production. In addition, the use of nano-based fertilizer and pesticides as effective materials in nano-priming and plant growth development were also discussed, considering their recent status and future perspectives.

Nickel sulfides are rich chemistry groups with discrete phases and stoichiometries, therefore they have various properties and applications. We herein prepare two single metal xanthate precursors [K(S2COBu)] Potassium butyl xanthate and [K(S2COPn)] Potassium pentyl xanthate using the melting method at two different temperatures 400 and 500°C to synthesize nickel sulfides nanoparticles. The nanoparticles were characterized using powder X-ray diffraction (p.XRD), energy-dispersive X-ray spectroscopy (EDX) and imaged using scanning electron microscopy (SEM). Two different nickel sulfides nanostructures obtained [Ni(S2COBu)3] and [Ni(S2COPn)3], the results from p.XRD show the sizes of the nanoparticles are (35.39±8.15 and 38.24±7.70 nm) at 400oC respectively, and (43.12±4.52 and 47.45±4.22 nm) respectively at 500oC. The result shows that the xanthate ligand affects the size of the nanoparticles as by increasing the alkyl chain length the size of the nanoparticles decrease. The (SEM) images show coral-like agglomerates, which are mainly assembled by spherical nanoparticles. EDX analysis shows stable and pure nickel sulfides with some variations in the elemental ratio of both nickel and sulfur according to the xanthate ligand used as a precursor to synthesis the nanoparticles. As a result, we introduce a simple, low cost and feasible synthesis of pure, stable, with definite size two nickel sulfides nanoparticles using metal xanthate ligands.
