DOPA synthesis in non-producer cultures of Mucuna deeringiana

Phytochemistry, 1980
Abstract Cell cultures of Mucuna deeringiana on various media fail to accumulate DOPA or stizolobic acid. Radiotracer studies prove that both compounds are being synthesized in the cells; however, the apparent lack of production is due to metabolic emphasis on catabolism instead of storage.

Tolerance to acid soil conditions of the velvet beans Mucuna pruriens var. utilis and M. deeringiana

Plant and Soil, 1991
Velvet beans, fast growing leguminous cover crops used in the humid tropics, are shallow rooted on acid soils. This might be due to an inherent branching pattern, to an intrinsic toxicity of the acid subsoil or to a relative preference for root development in the topsoil.

Dopa ring-cleavage in the biogenesis of stizolobic acid in Mucuna deeringiana

Phytochemistry, 1976
Abstract Tyrosine and DOPA are specifically incorporated into stizolobic acid in young leaves of M. deeringiana . The biosynthesis of this heterocyclic amino acid must, therefore, involve 4,5-extra-diol ring-cleavage of the aromatic ring of DOPA and subsequent cyclization.

Aluminium tolerance of the velvet beans Mucuna pruriens var. utilis and Mucuna deeringiana

1990
Although Al is generally regarded a nonessential element, in nutrient solution studies at pH 4.2 with NO3 as nitrogen source an Al3+concentration of 0.33 meqL−1, increased root fresh weight of M. p. utilis and M. deeringiana but not shoot fresh weight. The two species did not differ essentially in their response to aluminium.

Tolerance to acid soil conditions of the velvet beans Mucuna pruriens var. utilis and M. deeringiana

Plant and Soil, 1993
Fast growing, climbing leguminous cover crops such as the velvet beans can be used to reclaim weed-infested, degraded soils in the humid tropics, especially land covered by the grass Imperata cylindrica; they climb over the grass leaves and shade the grass out if their cover lasts long enough. Tolerance of two species of velvet bean to eroded soils was

Metal-resistant rhizobacteria isolates improve Mucuna deeringiana phytoextraction capacity in multi-metal contaminated soils from a gold mining area

Environmental Science and Pollution Research, 2016
Phytoremediation consists of biological techniques for heavy metal remediation, which include exploring the genetic package of vegetable species to remove heavy metals from the environment. The goals of this study were to investigate heavy metal and bioaugmentation effects on growth and nutrient uptake by Mucuna deeringiana; to determine the metal ...

CARACTERIZACION DE RIZOBACTERIAS DE LA Mucuna deeringiana Y EL PLATANERO

1997
Muestras de suelo y raices tomadas de parcelas con mucuna, platanero y mucuna-platanero en asociaciôn fueron evaluadas con el objetîvo de determinar poblaciones de bacterias de la rizosfera. Las rizobacterias se aislaron en Agar de Soya Tripticasa al 5% usando el método de dilution seriada.

Mucuna deeringiana (Bort) Merr. y el picudo del cormo, Cosmopolites sordidus Germar (Coleoptera: Curculionidae), en plátano

The Journal of Agriculture of the University of Puerto Rico, 2005
Se estudió el efecto de la leguminosa Mucuna deeringiana sobre la densidad poblacional y daño al cormo por Cosmopolites sordidus en plátano. Se estudiaron dos sistemas de siembra: mucuna intercalada y mucuna como cobertera verde. Se estudió además la relación de la densidad de adultos de C. sordidus y el daño por la larva al cormo.
