Molecular mechanisms associated with rootstock–scion interactions in rubber trees

The Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Hevea brasiliensis (rubber tree) is the main source of natural rubber worldwide. In commercial plantations, high‐yield rubber tree clones are propagated by grafting onto seedling rootstocks. In this study, the transcriptomes of the RRIM 600 clone grafted on different rootstocks in southeastern Brazil were evaluated. Exclusively expressed genes

Suppression of humoral immunity and lymphocyte responsiveness during experimental trypanosoma cruzi infections Supresión de la inmunidade humoral y de la respuesta linfocitaria durante la infección experimental con Trypanosoma cruzi

Revista do Instituto de Medicina Tropical de São Paulo, 1984
C3H/He and C57B1/6 mice were inoculated with 500 Trypanosoma cruzi trypomastigotes (Strain Y). During the acute phase infected mice presented parasitemia and enlargement of lymph nodes and spleens and intracellular parasites were observed in the heart ...

A novel single‐cell NAD‐ME C4 subtype integrated with CAM and bicarbonate use in an aquatic plant

New Phytologist, Volume 249, Issue 5, Page 2386-2401, March 2026.
Summary Many plants maximize photosynthesis by using a CO2‐concentrating mechanism (CCM). Based on physiology, the freshwater plant Ottelia alismoides has three CCMs: C4 metabolism (NAD‐malic enzyme (NAD‐ME) subtype) and bicarbonate‐use during the day plus crassulacean acid metabolism (CAM) at night and lacks Kranz anatomy. Here, we combined a range of

Influence of the Azores high on sea level pressure and wind, and on precipitation, in the Eastern Tropical Pacific Ocean [PDF]

, 1966
ENGLISH: Intensification of the Azores high pressure cell in mid-year, with concomitant air flow from the Caribbean into the Pacific, is shown to be responsible for a secondary minimum of precipitation observed along the tropical Pacific coast of the ...

Polysaccharide‐Coated ETCA Nanoparticles Containing the Methoxyl Substituted Indole‐Thiazole Derivative and Their Antiproliferative Activity in Breast Cancer Cells

Journal of Applied Polymer Science, Volume 143, Issue 4, January 20, 2026.
ABSTRACT Indole and thiazole derivatives have garnered significant attention due to their potent antitumor activities. Encapsulation of such derivatives into polymeric nanoparticles offers several advantages, including improved molecular stability and targeted delivery to tumor sites, thereby enhancing their antineoplastic potential.

Formación de linajes bacterianos en Salmonella enterica por mecanismos epigenéticos [PDF]

, 2017
Mientras que la capacidad de las células eucarióticas para diversificarse en linajes se describe incluso en los libros de texto, tradicionalmente se ha considerado que las bacterias eran clones de células idénticas.

Conserved spatial patterning of gene expression in independent lineages of C4 plants

New Phytologist, Volume 249, Issue 1, Page 24-38, January 2026.
Summary C4 photosynthesis enhances carbon fixation efficiency by reducing photorespiration through the use of an oxygen‐insensitive carboxylase and spatial separation of photosynthesis between mesophyll and bundle sheath cells. The C4 pathway has evolved independently in > 60 plant lineages, but molecular mechanisms underpinning this convergence remain
