A new species of Lauraceae, M.Z.Zhang, Yahara & Tagane, from Kaeng Krachan National Park, Phetchaburi Province, southwestern Thailand, is described and illustrated. This species is morphologically most similar to in that its leaves are pinnately veined, leathery, and apparently glabrous (but microscopically hairy) abaxially, twigs are yellowish brown hairy, and fruits are 1.36 to 1.85 times longer than width. However, is distinguished from in having the leaves of ovate and elliptic (vs. oblong-lanceolate) with leaf aspect ratio (length:width) from 1.38 to 2.28 (vs. 2.46-3.43), and ovoid fruits (vs. ellipsoid) with stalk distinctly swollen (vs. not or only slightly swollen). In addition, phylogenetic trees constructed based on internal transcribed spacer sequences (ITS) and genome-wide SNPs using MIG-seq showed that is not sister to and is distinct from all the other species hitherto recognized in Thailand. Analysis including other species demonstrates that should be a synonym of , but we recognize as a distinct species.

Cinnamomum parthenoxylon is a significant essential oil plant in southern China, however, the challenge of rooting cuttings poses a hindrance to its development and widespread cultivation. Adventitious root (AR) formation is a vital mechanism for plants to acclimate to environmental changes, yet the precise regulatory mechanisms governing this process remain largely unknown. This study investigated the morphological, physiological, and transcriptomic alterations during AR formation in C.

2'-Hydroxycinnamaldehyde (HCA), a natural product isolated from the bark of , has anti-inflammatory and anti-tumor activities. In this study, we explored whether HCA preconditioning could protect the heart against ischemia/reperfusion (I/R)-induced oxidative injury through cytosolic Bcl-2-associated athanogene 3 (BAG3) upregulation. In vivo HCA preconditioning was performed intraperitoneally in adult male Wistar rats (50 mg/kg body weight) three times/week for 2 weeks before cardiac I/R injury.

In the present work, 32 gracillariid species from South Africa are treated. For each species, hostplant and distribution information is provided, supplemented by taxonomic and molecular analysis where necessary.
