Article Abstract
is a well-known ethnobotanical herb for the treatment of various diseases in Iranian traditional medicine. In this study, dichloromethanolic fraction of partitioned methanol root and shoot extract was analysed by silica gel column chromatography, thin layer chromatography and high-performance liquid chromatography combined with photodiode-array detector, and coupled to electrospray ionization with Q-Exactive Orbitrap mass spectrometry (HPLC-PDA-ESI-MS) in positive ion mode. Metabolites were tentatively characterized by comparing their mass spectrometry spectra with those of bibliographic data. A total of 11 flavonoids were identified from different fractions. Results showed that root and shoot produced very similar flavone patterns characterized by the presence of baicalein, tricin, tenaxin I, tenaxin II, skullcapflavon II, chrysin, wogonin and isorhamnetin. Norwogonin and apigenin-7-glucoside were identified only from shoot. Remarkably, Tenaxin I, II, tricin, apigenin-7-glucoside and norwogonin were tentatively profiled as new compounds for the first time from formula.

Water deficit stress causes devastating loss of crop yield worldwide. Improving crop drought resistance has become an urgent issue. Here we report that a group of abscisic acid (ABA)/drought stress-induced monocot-specific, intrinsically disordered, and highly proline-rich proteins, REPETITIVE PROLINE-RICH PROTEINS (RePRPs), play pivotal roles in drought resistance in rice seedlings.

Natural soils are reservoirs of potentially beneficial microbes that can improve plant performance. Here, we isolated 75 bacterial strains from surface-sterilised roots of Arabidopsis thaliana (Arabidopsis) grown in a natural soil derived from an alder swamp. Culture-dependent isolation of individual strains from the roots, followed by monoassociation-based screening, identified seven bacteria that promoted Arabidopsis seedling weight.

Balsa (Ochroma lagopus Swartz), the world's lightest wood and a crucial material in wind turbine blades, holds significant potential to contribute to carbon neutrality efforts when cultivated in tropical areas such as Xishuangbanna, China. However, balsa trees planted in Xishuangbanna exhibit early branching, resulting in reduced wood yield. Our study investigated the pivotal factors in regulating shoot apical dominance and branching by comparing an early-branching cultivar from Indonesia with a late-branching cultivar from Ecuador.

The accumulation of antibiotics in soil threatens agricultural ecosystems and human health. Oxytetracycline (OTC), a plant-absorbable antibiotic, generally exerts inhibitory effects on plant growth. Selenium (Se) plays a crucial role in safeguarding plants resistant to a variety of abiotic stresses.
