Structural organization in palm stems of Roystonea regia and Archontophoenix alexandrae
IAWA Journal, 2020Abstract Having a high stature subjects palms to the same constraints as trees, but the lack of cambial growth urges them to adopt a different strategy. We aimed to characterize the spatial organization of xylem tissues and their potential functions in two palm stems: a 30 cm diameter at breast height (DBH) royal palm (Roystonea regia) and a 12 cm DBH ...

Roystonea regia a monocotyledonous tree, bears rhizobial root nodules
Folia Microbiologica, 1997The first instance of a monocotyledonous treeRoystonea regia (royal palm) bearing root nodules is reported. They are formed by a Gram-negative bacterium which was tentatively identified asRhizobium sp. The nodules are formed on younger roots of the tree mostly in the rainy season. Younger plants also become nodulated.

A new helicosporous hyphomycete collected on Roystonea regia in Cuba
Mycological Research, 1996A unique hyphomycete, Rogergoosiella roystoneicola gen. et sp. nov., is described and illustrated from dead petioles of Roystonea regia collected in Cuba. Its relationship with other helicosporous hyphomycetes is discussed.

A Potyvirus Isolated From Cuban Royal Palm (Roystonea Regia) in Queensland.
Australasian Plant Pathology, 1993Chlorotic ringspot symptoms were noted on Cuban royal palms (Roystonea regia) from two locations in south-east Queensland. A virus, provisionally named Roystonea palm virus (RoPV), was isolated from these plants. It was mechanically transmitted to Chenopodium amaranticolor, C. quinoa, Nicotiana benthamiana, N.

Oral Subchronic Toxicity of a Lipid Extract fromRoystonea regiaFruits in Mice
Drug and Chemical Toxicology, 2008D-004 is a lipid extract of royal palm (Rosytonea regia) fruits that prevents prostate hyperplasia induced with testosterone in rodents. Previous studies have shown no D-004-related toxicity in rats, but no study in mice had been reported. D-004 (500, 1000, and 2000 mg/kg) was evaluated in a subchronic (eight weeks) study in NMRI mice.

Peroxidase from leaves of royal palm tree Roystonea regia: purification and some properties
Plant Science, 2001Abstract Screening of tropical plants demonstrated high peroxidase activity in leaves of some species of palms. Using the leaves of royal palm Roystonea regia as a source, the peroxidase has been isolated to homogeneity. The enzyme purification steps included homogenization, (NH 4 ) 2 SO 4 precipitation, extraction of palm leaf colored compounds ...

This study investigated the properties of hybrid composites made from Roystonea-Regia and banana fibers for potential applications in industries requiring lightweight, environmentally favorable, and mechanically strong materials. The analysis of density and void fraction revealed that the addition of banana fibers increased the composite's density ...

Unveiling root nodulation in Tribulus terrestris and Roystonea regia via metagenomics analysis
Molecular Genetics and GenomicsRoot nodule symbiosis is traditionally recognized in the Fabales, Fagales, Cucurbitales, and Rosales orders within the Rosid I clade of angiosperms. However, ambiguous root nodule formation has been reported in Zygophyllaceae and Roystonea regia (Arecaceae), although a detailed analysis has yet to be conducted.

Roystonea regia and Ptychosperma macarthurii are exotic palm species widely grown in Nigeria as ornamentals. The kernels of R. regia and P. macarthurii were subjected to amino acids, fatty acids, and mineral elements analyses in this study. Glutamic acid (13. 64 and 14.00 g/100 g), aspartic acid (9.72 and 9.50 g/100 g), arginine (8.68 and 7.49 g/100 g),
