Background and Objective: Climate change influence crops through its effects on the growing, development and yield. Research on climate change risk in staple food crops has been implemented in South Sumatra, Indonesia. The objective of this study was to assess level of climate change risk in staple food crops production (paddy, corn and soybean). Materials and Methods: This study used data of temperature, rainfall, sea level rise, hythergraph, irrigation, production of staple food crops and…

Different metabolic response patterns between the BPH-susceptible and B PH-resistant varieties during BPH infestation are revealed, suggesting that these secondary metabolites play important roles in inducible and constitutive defenses against the B PH infestation.
Photoperiod modulates growth and pigments and 20-hydroxyecdysone accumulation in Brazilian ginseng [Pfaffia glomerata (Spreng.) Pedersen] grown in vitro

Phytoecdysteroid and Clerodane Content in Three Wild Ajuga Species in Israel
- Environmental ScienceACS Omega
- 2019
This work identified and quantified phytoecdysteroid and clerodane contents in three Ajuga plant species in Israel and identified the highest concentrations of 20-hydroxyecdysone, makisterone A, and cyasterone were recorded in leaves and roots of A. iva.
Identification of Genes Involved in Resistance to High Exogenous 20-Hydroxyecdysone in Spodoptera litura
- BiologyInsects
- 2022
The molecular mechanism to explain how noctuid pest (Spodoptera litura) resist high dosage of 20E is dissected, finding that the S. litura show resistance to artificial foods containing a high level of 20-hydroxyecdysone (20E), the major form of phytoecdysteroids, without any adverse effects on growth and development.

Identification and Characterization of Genes Involved in Ecdysteroid Esterification Pathway Contributing to the High 20-Hydroxyecdysone Resistance of Helicoverpa armigera
- BiologyFrontiers in Physiology
- 2020
The cotton bollworm Helicoverpa armigera larvae show high tolerance to artificial foods containing up to 50 μg 20E without any detrimental effects on growth and development and high performance liquid chromatography analysis indicates that high efficiency to transform 20E through an ecdysteroid esterification pathway may contribute to the resistance.
Accessions of Brazilian ginseng (Pfaffia glomerata) with contrasting anthocyanin content behave differently in growth, antioxidative defense, and 20-hydroxyecdysone levels under UV-B radiation
- Medicine, ChemistryProtoplasma
- 2019
It is shown that UV-B radiation is a potential elicitor for increasing 20E content in P. glomerata grown in vitro, and Notably, A43 displayed 56% more anthocyanin to the former, a possible defense againstUV-B.
