Tropical Rainforests Exhibit Higher Multidimensional Stability Than Rubber Plantations Despite Lower Resistance to Temperature Anomalies

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Rapid rubber plantations (RB) expansion in Southeast Asia raises critical questions about regional ecosystem stability. We compared stability between monoculture RB and diverse tropical rainforests (RF) using 37 years of satellite‐derived gross primary productivity across three metrics: long‐term temporal stability, resilience, and resistance ...

Trade‐Offs Between Carbon and Water Fluxes Along a Land Use Intensity Gradient in Southeast Asian Forests and Plantations

Global Change Biology, Volume 32, Issue 2, February 2026.
Increase land use intensity may enhance net carbon uptake in fast‐growing species on mineral soil but concurrently increases the risk of water scarcity. Net carbon uptake and evapotranspiration in high land use intensity sites are more affected by water availability compared to low land use intensity sites.

Some ethylene biosynthesis and AP2/ERF genes reveal a specific pattern of expression during somatic embryogenesis in Hevea brasiliensis

BMC Plant Biology, 2012
Background Ethylene production and signalling play an important role in somatic embryogenesis, especially for species that are recalcitrant in in vitro culture. The AP2/ERF superfamily has been identified and classified in Hevea brasiliensis.

Combined Transcriptomic and Metabolomic Analysis Reveals an Ethylene‐Activated Regulatory Model on Monoterpenoid Indole Alkaloid Biosynthesis in Catharanthus roseus

Plant Biotechnology Journal, Volume 24, Issue 2, Page 363-380, February 2026.
ABSTRACT Catharanthus roseus contains nearly 200 bioactive monoterpenoid indole alkaloids (MIAs) that are effective in treating cancer and other diseases. Ethylene plays a significant role in enhancing MIA biosynthesis, and we have found that it greatly induces the accumulation of anhydrovinblastine.

Identification of novel microRNAs in Hevea brasiliensis and computational prediction of their targets

BMC Plant Biology, 2012
Background Plants respond to external stimuli through fine regulation of gene expression partially ensured by small RNAs. Of these, microRNAs (miRNAs) play a crucial role.

L‐Quebrachitol Enhances Sedative Effect of Diazepam Through GABAergic Pathway: Animal and Computational Studies

Brain and Behavior, Volume 16, Issue 1, January 2026.
L‐quebrachitol (LQL) significantly enhanced the sedative effects of diazepam in thiopental sodium‐induced chicks by reducing sleep latency and prolonging duration. Molecular docking revealed LQL's interaction with GABAA receptor (α1 and β2 subunits), supporting a GABAergic mechanism and highlighting its potential as a safe, natural sedative agent ...

The phosphatides of Hevea Brasiliensis [PDF]

Biochemical Journal, 1942
Abstract The presence of phosphatide in Hevea latex had long been suspected, but it was not until 1931 that Rhodes and Bishop isolated phosphatidic material containing 0.59 per cent nitrogen and 1.72 per cent phosphorus from the serum of latex which had been coagulated with ethanol.

Characterization of a vacuolar sucrose transporter, HbSUT5, from Hevea brasiliensis: involvement in latex production through regulation of intracellular sucrose transport in the bark and laticifers

BMC Plant Biology, 2019
Background Sucrose (Suc), as the precursor molecule for rubber biosynthesis in Hevea brasiliensis, is transported via phloem-mediated long-distance transport from leaves to laticifers in trunk bark, where latex (cytoplasm of laticifers) is tapped for ...
