Research on silicon (Si), an element considered beneficial for plant growth, has focused abiotic and biotic stress mitigation. However, the effect of Si tomato fruit quality under normal growth conditions remains unclear. This study investigated effects applying different levels (0 mmol·L−1 [CK], 0.6 [T1], 1.2 [T2], 1.8 [T3]) in foliar sprays cultivated substrates, most level was found. Compared to CK, exogenous treatments had a positive influence appearance nutritional fruits at mature green, breaker, red ripening stages. Of these, T2 treatment significantly increased peel firmness single-fruit weight fruits. The contents soluble sugars, solids, proteins, vitamin C were higher, nitrate content lower than CK treatment.

Colonization of Piriformospora indica enhances rice resistance against the brown planthopper Nilaparvata lugens

Pest Management Science, Journal Year: 2024, Volume and Issue: 80(9), P. 4386 - 4398

Published: April 25, 2024

Abstract BACKGROUND Piriformospora indica is an endophytic fungus that can promote the growth and confer resistance against diverse stresses in host plants by root colonization. However, effects of P. colonization on improving plant to insect pests are still less explored. The brown planthopper (BPH) Nilaparvata lugens a serious monophagous pest causes extensive damage rice plants. Here, we aimed evaluate BPH. RESULTS roots resisted from Age‐stage, two‐sex life table analyses showed feeding indica‐ colonized affected BPH's female adult longevity, oviposition period, fecundity, population parameters size. BPH adults excreted honeydew. remarkably increased duration np, N2, N3 waveform, as well occurrences N1 decreased N4‐b for Meanwhile, weight was significantly lower than control. In addition, preferences ‐colonized were reduced. qRT‐RCR revealed induced expressions jasmonic acid (JA)‐ salicylic (SA)‐related genes CONCLUSION reduce performance with potential inhibitory growth. Collectively, these results support endophytically effective strategy improve crops. © 2024 Society Chemical Industry.

From trade-off to synergy: how nutrient status modulates plant resistance to herbivorous insects?

Advanced Biotechnology, Journal Year: 2024, Volume and Issue: 2(4)

Published: Oct. 8, 2024

The principle of the "growth-defense trade-off" governs how plants adjust their growth and defensive strategies in response to external factors, impacting interactions among plants, herbivorous insects, natural enemies. Mineral nutrients are crucial modulating plant development through bottom-up effects. Emerging evidence has revealed complex regulatory networks that link mineral defense responses, influencing delicate balance between against herbivores. This review aims summarize recent advances elucidate impact nutrient availability on responses. Particularly, we focus status shapes resistance herbivores, delving into molecular mechanisms underlying this physiological process. Moreover, interplay various herbivore mechanisms, including physical protection, hormone signaling, metabolite production, volatile organic compound emissions deter herbivores or attract enemies, discussed. comprehensive sets stage for future investigations intricate crosstalk signaling which serves as a central mechanism guide sustainable pest management approaches, thereby promoting balanced agroecosystem health enhancing ecosystem productivity resilience.

Natural Enemies Acquire More Prey Aphids from Hormone-Treated Insect-Attracting Plants

Plants, Journal Year: 2025, Volume and Issue: 14(2), P. 147 - 147

Published: Jan. 7, 2025

Exogenous plant hormones regulate the agronomic and physiological performance of plants thus can influence abundance insect groups. We surveyed arthropods on flowering Cnidium monnieri found that natural enemies Propylaea japonica Orius minutus in plots treated with salicylic acid (SA) indole acetic (IAA) was significantly increased compared those clean water (control) plots. Then, we investigated effects spraying SA, IAA, population parameters Semiaphis heraclei reared C. monnieri. Our results from age-stage, two-sex life table analysis revealed a shorter pre-adult duration for aphids SA-treated to other two treatments. The intrinsic rate increase, finite net reproductive SA- IAA-treated were higher than water-treated fecundity under SA IAA treatments control, but difference not significant. This improved ability attract by providing larger food source.

Rice Defense Responses Orchestrated by Oral Bacteria of the Rice Striped Stem Borer, Chilo suppressalis

Rice, Journal Year: 2023, Volume and Issue: 16(1)

Published: Jan. 9, 2023

Plant defenses in response to chewing insects are generally regulated by jasmonic acid (JA) signaling pathway, whereas salicylic (SA) is mainly involved plant defense against biotrophic pathogens and piercing-sucking insects. Previous studies showed that both JA- SA-related rice plants were triggered the infestation of striped stem borer (SSB, Chilo suppressalis), a destructive pest causing severe damage production. Herbivore-associated microbes play an important role modulating plant-insect interaction, thus we speculate SSB symbiotic acting as hidden player may cause this anomalous result. The antibiotics (AB) treatment significantly depressed performance field-collected larvae on plants, reduced quantities bacteria around wounds stems compared non-AB treatment. In mechanical wounding oral secretions (OS) collected from treated larvae, exhibited lower levels JA-regulated defenses, but higher SA-regulated OS AB-treated determined using combination biochemical molecular methods. Among seven culturable isolated Enterobacter Acinetobacter contributed suppression JA signaling-related axenic reinoculated with these two strains displayed better plants.

Heterosis for Resistance to Insect Herbivores in a 3-Line Hybrid Rice System

Insects, Journal Year: 2024, Volume and Issue: 15(3), P. 164 - 164

Published: Feb. 28, 2024

Three-line hybrid rice is produced by crossing male sterile (A line) with a fertility-restorer (R line). Fertile lines (B lines) are also required to maintain A line seed for breeding programs. We used range of hybrids and their parental assess the frequency nature heterosis resistance whitebacked planthopper (Sogatella furcifera), brown (Nilaparvata lugens) yellow stemborer (Scirpophaga incertulas). Heterosis defined as trait improvement above average result outbreeding. Based on results from greenhouse study that challenged each herbivore species, we found susceptibility planthoppers was associated one eight tested, but improved relatively resistant restorer. Higher frequencies in comparisons between B suggest not related cytoplasmic genomes lines. Furthermore, because none possessed currently effective genes, against probably due quantitative resistance. In field trial, had generally higher yields than fertile parents often larger grain; however, they were more susceptible stemborers, leaffolders (Cnaphalocrocis medinalis) other caterpillars (Rivula atimeta). This largely consequence plant biomass strongly affected crop duration. make series recommendations improve reduce risks damage.
