A cell‐type‐specific regulon controlling monoterpene indole alkaloid biosynthesis with feedback and feedforward activation loops

New Phytologist, Volume 249, Issue 2, Page 945-960, January 2026.
Summary Monoterpene indole alkaloids (MIA) are a diverse class of plant natural products produced by a subset of lineages within the Asterid clade of eudicots. The diversity of MIAs provides a unique opportunity to study not only the evolution of biosynthetic genes but also their regulation.

Transient Sensorineural Hearing Loss and Rhabdomyolysis, Associated With Chronic Kratom Use

Case Reports in Otolaryngology, Volume 2026, Issue 1, 2026.
Kratom is a colloquial name for products derived from the mitragyna plant species originating in Southeast Asia and now widely available in the United States as a dietary supplement. Kratom is used primarily for self‐management of pain, anxiety, and opioid withdrawal due to its partial agonist activity on mu opioid receptors, as well as other ...

Floristic Diversity and Use of Woody Plants in the Magayel and Barkaya Forests (Far North, Cameroon)

The Scientific World Journal, Volume 2026, Issue 1, 2026.
The Magayel and Barkaya forest massifs located in the Far North Region of Cameroon are rich in biodiversity. In this study, we sought to document the floristic diversity and the use of plant resources by the local populations surrounding the Magayel and Barkaya forest massifs. A total of 12 transects (30 × 1000 m) were established in each forest massif

The 730 nm Picosecond Titanium Sapphire Laser for Treatment of Kratom‐Induced Hyperpigmentation

Lasers in Surgery and Medicine, Volume 57, Issue 5, Page 373-382, July 2025.
ABSTRACT Objectives This case series reports the use of the 730‐nm picosecond titanium‐sapphire laser in the treatment of kratom‐induced hyperpigmentation, a dermatological side effect associated with the use of Mitragyna speciosa, which remains poorly understood. Methods A series of patients with kratom‐induced hyperpigmentation were treated using the
