Abstract One of the most devastating diseases apples is scab, caused by fungus Venturia inaequalis . Most commercial apple varieties are susceptible to this disease; only a few resistant. Breeding approaches being used develop better that resistant scab. Volatile organic compounds (VOCs) contribute greatly plant's phenotype, and their emission profile largely depends on genotype. In non‐destructive phenotyping plants, VOCs can be as biomarkers. study, we assessed non‐destructively scab tolerance potential (cv. ‘Prima’) ‘Oregon Spur’) cultivars comparing major leaf VOC compositions relative proportions. A comparison profiles two revealed 16 different VOCs, with cis ‐3‐hexenyl acetate (3HA) emerging biomarker cultivar differences. V. growth was significantly inhibited in vitro 3HA treatment. effective reducing symptoms ‐inoculated leaves Spur.’ The ‘Prima’ also exhibited higher lipoxygenase (LOX) activity α‐linolenic acid (ALA) levels, suggesting resistance linked LOX biosynthesis. This study proposes for rapid screening scab‐resistant germplasm based VOCs.

ABSTRACT Wheat ( Triticum aestivum L.) is one of the most important staple crops all over world. Its productivity adversely affected by aphid infestation. Plant volatiles play a critical role in plant communication, inducing direct and indirect defenses against insect pests. However, little known about priming mechanism key wheat. To determine whether how volatile induced defense wheat grain Sitobion avenae , combination bioassays, phytohormone metabolite quantification, transcriptome analyses were performed using an damage‐induced volatile, methyl salicylate (MeSA). MeSA treatment primed for enhanced accumulation salicylic acid, flavonoid benzoxazinoids (BXs), increased resistance to S. attractiveness parasitoid Aphelinus asychis . Supplementation with BX (2,4‐dihydroxy‐7‐methoxy‐2H‐1,4‐benzoxazin‐3(4H)‐one) two flavonoids (xanthohumol isobavachalcone) artificial diet impaired survival, development fecundity Moreover, emission especially MeSA. Functional investigation odorant‐binding proteins (OBPs) A. revealed that AasyOBP4 responsible recognition Taken together, our results provide insights into molecular MeSA‐mediated propose as phytoprotectant crop protection sustainable agriculture.

While organophosphorus chemistry is gaining attention in a variety of fields, the synthesis phosphorus derivatives amino acids remains challenging task. Previously reported methods require deprotonation nucleophile, complex reagents or hydrolysis phosphonate ester. In this paper, we demonstrate how to avoid these issues by employing phosphonylaminium salts for novel mixed n-alkylphosphonate diesters acid-derived n-alkylphosphonamidates. We successfully applied methodology N-acyl homoserine lactone analogues with varying alkyl chains and ester groups moiety. Finally, developed rapid, quantitative high-throughput bioassay screen selection compounds their herbicidal activity. Together, results will aid future research chemistry, agrochemistry bioactive targets.
