Many parts of the Calotropis gigantea plant are known to contain bioactive compounds, but leaves contain the most. This study aimed to determine the toxicity and antifeedant activity of C. gigantea leaves against Plutella xylostella. The study was carried out from November 2019 to July 2020. Toxicity was tested using the leaf dipping and spraying methods. Antifeedant activity was tested using a no-choice test and a choice test. Identification of the compound composition of the leaf extract of C. gigantea was carried out at the Integrated Research and Testing Laboratory, Gadjah Mada University. Extract toxicity data obtained were analyzed by Probit analysis. The results showed that the antifeedant activity of C. gigantea leaf extract a no-choice and with choice at each concentration had a significant effect on the consumption of P. xylostella larvae rations. The toxicity (LC50) of the leaf extract of C. gigantea to P. xylostella by the dipping method was 2,958 µgl-1 while the spraying application was 3.944 µgl-1. The composition of chemical compounds contained in the leaf extract of C. gigantea is saponins, alkaloids, flavonoids, tannins, phenols, terpenoids. With the composition of these chemical compounds, the leaf extract of C. gigantea has the potential as a source of vegetable insecticide compounds against P. xylostella.

“…Most plants bear destruction from biotic and abiotic stress agents ( Zaynab et al, 2020 ), which influence their productivity and survival rate throughout their life cycle ( Zaynab et al, 2018 ). DDPs are implicated in several regulatory processes, including development, growth, biotic and abiotic stresses ( Zaynab et al, 2021e ). Plants have evolved tolerance systems to change their cellular biochemistry and physiology during stress by changing gene expression ( Zaynab et al, 2017 ).…”

The domain of the unknown function 221 proteins regulate several processes in plants, including development, growth, hormone transduction mechanism, and abiotic stress response. Therefore, a comprehensive analysis of the potato genome was conducted to identify the deafness-dystonia peptide (DDP) proteins’ role in potatoes. In the present study, we performed a genome-wide analysis of the potato domain of the unknown function 221 (DUF221) genes, including phylogenetic inferences, chromosomal locations, gene duplications, gene structures, and expression analysis. In our results, we identified 10 DDP genes in the potato genome. The phylogenetic analysis results indicated that StDDPs genes were distributed in all four clades, and clade IV was the largest clade. The gene duplication under selection pressure analysis indicated various positive and purifying selections in StDDP genes. The putative stu-miRNAs from different families targeting StDDPs were also predicted in the present study. Promoter regions of StDDP genes contain different cis-acting components involved in multiple stress responses, such as phytohormones and abiotic stress-responsive factors. The analysis of the tissue-specific expression profiling indicated the StDDPs gene expression in stem, root, and leaf tissues. We subsequently observed that StDDP4, StDDP5, and StDDP8 showed higher expressions in roots, stems, and leaves. StDDP5 exhibited high expression against heat stress response, and StDDP7 showed high transcript abundance against salt stress in potatoes. Under abscisic acid (ABA) and indole acetic acid (IAA) treatments, seven StDDP genes’ expressions indicated that ABA and IAA performed important roles in immunity response. The expression profiling and real-time qPCR of stems, roots, and leaves revealed StDDPs’ significant role in growth and development. These expression results of DDPs are primary functional analysis and present basic information for other economically important crops.

“…Previous studies have shown that plant metabolites and microbiota contribute to host plant defense against pathogens ( 19 – 21 ). For example, previous studies have summarized the important role of polysaccharide ( 22 , 23 ) and steroidal and triterpenoid saponin toxins ( 24 , 25 ) in disease resistance. Similarly, there is increasing evidence that the root/rhizosphere microbiota directly or indirectly participate in host plant metabolic processes by regulating host secondary or special metabolism ( 19 , 26 , 27 ).…”
