“…In the current study, 100% germination percentage, maximum mean germination time, high root length, and enhanced chlorophyll content were attained by some of the genotypes, which could be due to difference in the genetic background of the studied wheat genotypes and the optimal priming duration of 12 h as previously reported . The same has previously been reported for other crops also, including maize, beans, finger millet, sorghum, pearl millet, rice, sorghum, maize, and cotton . This effect could be credited to the leakage of germination inhibitors into the priming solution and seed reserve premobilization during the priming period .…”

Seed priming is considered to play an essential role in the overall improvement of agricultural crops. The current research work was carried out in order to investigate the comparative effects of hydropriming and iron priming on the germination behavior and morphophysiological attributes of wheat seedlings. The experimental materials consisted of three wheat genotypes including a synthetically derived wheat line , stay-green wheat genotype (Chirya-7), and conventional wheat variety (Chakwal-50). The treatments included hydro (distilled and tap water)-and iron priming (10 and 50 mM) of wheat seeds for 12 h duration. Results indicated that both priming treatment and wheat genotypes exhibited highly different germination and seedling characteristics. These included germination percentage, root volume, root surface, root length, relative water content, chlorophyll content, membrane stability index, and chlorophyll fluorescence attributes. Furthermore, the synthetically derived line (SD-194) was the most promising in majority of the studied attributes by exhibiting a high germination index (2.21%), root fresh weight (7.76%), shoot dry weight (3.36%), relative water content (19.9%), chlorophyll content (7.58%), and photochemical quenching coefficient (2.58%) when compared with stay-green wheat (Chirya-7). The study also found that hydropriming with tap water and priming wheat seeds with low concentrations of iron yielded better results when a comparison was made with wheat seeds primed at high concentrations of iron. Therefore, wheat seed priming with tap water and iron solution for 12 h is recommended for optimum wheat improvement. Furthermore, current findings suggest that seed priming may have the prospect of an innovative and userfriendly approach for wheat biofortification with the aim of enhanced iron acquisition and accumulation in grains.

“…cantalupensis protected Oryza sativa L. and Solanum lycopersicum L. against root-knot nematodes by direct nematicidal effects and through resistance induced by the generation of reactive oxygen species (ROS) and ethylene accumulation and cell wall modification [ 132 ]. Arshad et al [ 133 ] found that seed priming with botanical extracts, Neem ( Azadirachta indica ), Datura ( Datura stramonium L.), Kortuma ( Citrullus colocynthis (L.) Schrad) and Moringa oleifera Lam. leaf extracts showed significant results in suppressing nematodes.…”

Root-knot nematodes (Meloidogyne spp.) are sedentary endoparasites that cause severe economic losses to agricultural crops globally. Due to the regulations of the European Union on the application of nematicides, it is crucial now to discover eco-friendly control strategies for nematode management. Biocontrol is one such safe and reliable method for managing these polyphagous nematodes. Biocontrol agents not only control these parasitic nematodes but also improve plant growth and induce systemic resistance in plants against a variety of biotic stresses. A wide range of organisms such as bacteria, fungi, viruses, and protozoans live in their natural mode as nematode antagonists. Various review articles have discussed the role of biocontrol in nematode management in general, but a specific review on biocontrol of root-knot nematodes is not available in detail. This review, therefore, focuses on the biocontrol of root-knot nematodes by discussing their important known antagonists, modes of action, and interactions.

“…Seeds were surface sterilized with 5% NaOCl and subsequently washed thrice with sterilized distilled water. The surface sterilized seeds were sown in earthen pots (9 × 9 × 10 cm) containing sterilized soil (Arshad et al, 2022). At four leaf stage, the plants were treated with bacterial strains by applying 10 mL of culture (10 7 CFU/mL) to each pot by soil drenching method according to Arshad et al (2022).…”

Plant-parasitic nematodes (PPNs) are a serious threat to food security. Root-knot nematodes (RKNs) are important plant parasitic nematodes that affect vegetable crops worldwide including okra. Among the RKNs, Meloidogyne incognita [(Kofold and White) Chitwood] is one of the major constraints to okra production. In this study, the effect of different bacterial strains i.e., Bacillus sp. MN54, Enterobacter sp. MN17 and Burkholderia. phytofirmans PsJN alone and in different combinations was assessed on plant growth promotion and inhibition of M. incognita infection on okra in a greenhouse experiment under completely randomized design (CRD). The results revealed that application of Enterobacter sp. MN17 significantly enhanced the root length (19.0), root weight (8.7), and shoot dry weight (19.6) as compared to other treatments. However, the combined treatment of Bacillus sp. MN54 + Enterobacter sp. MN17 + B. phytofirmans PsJN has successfully reduced the number of galls (10.5), number of females (23.2), egg masses (19.5), egg mass index (4.1), and galling index (2.1) against the RKNs. Conclusively, the combined application of all the bacterial strains was more effective in causing the suppression of RKNs and promotion of plant growth. This study illustrates the role of endophytic bacteria in controlling root knot nematode infection through the different changes in plants.
