Many trichomes in plant organs have been studied previously, but research on leaf several plants the Lamiaceae tribe has never before. The conducted at Laboratory of FKIP Palembang. This study using a descriptive method. used this were from family, such as Ocimum sanctum, Penorema canescens, Salvia splendens, Lavandula angustifolia, Hyptis rhomboides, Anisomeles indica, and Clerodendrum japonic...

Plant chemistry is an important contributor to the interaction with herbivores. Here, we report on a previously unknown role for foliar and glandular trichome volatiles in their interaction with the specialist herbivore of solanaceous plants, the tomato red spider mite Tetranychus evansi. We used various bioassays and chemical analyses including coupled gas chromatography-mass spectrometry (GC/...

We have previously reported the use of a combination of computational simulations and targeted experiments to build a first generation mathematical model of peppermint (Menthaxpiperita) essential oil biosynthesis. Here, we report on the expansion of this approach to identify the key factors controlling monoterpenoid essential oil biosynthesis under adverse environmental conditions. We also inve...

Flavonoids are a class of metabolites found in many plant species. They have been reported to serve several physiological roles, such as in defense against herbivores and pathogens and in protection against harmful ultraviolet radiation. They also serve as precursors of pigment compounds found in flowers, leaves, and seeds. Highly methylated, nonglycosylated derivatives of the flavonoid myricet...

The sesquiterpene contents in leaves of wild Rosa rugosa and of sixty-one hybrid rugosas were quantitatively measured by a GC analysis. In this group of samples, the greater the number of glandular trichomes the hybrid rugosas possessed on their leaves, the larger the amount of sesquiterpenes they accumulated. In contrast, those having no leaf glandular hairs contained only a trace amount of se...
