Honey locust

Eor practical purposes, the sapwood of all species may be considered to be susceptible to biodeterioration. The heartwood of some species, however, contains toxic extractives that protect it against biological attack. Among the native species that have decay-resistant or highly decay-resistant heartwood are bald cypress, redwood, cedars, white oak, black locust, and black walnut (60). Douglas-fir, several of the pines, the larches, and honey locust...

McCleary and Matheson252 showed the presence of two forms of /3-D-mannosidase in the seeds of guar, lucerne, carob, and honey locust. Form A (low molecular weight) was located in the cotyledon-embryo part, whereas (the larger) form B was in the endosperm. They suggested252 that, although the enzyme activity in these... 

Many tree-sized species in the legume family are valuable for their hard, durable timber. North American species are relatively minor in this respect, although the Kentucky coffee tree, black locust, and honey locust are used as lumber to some degree. 

A spine or thorn is the indurated termination of a stem tapering to a point, as the thorns of the Honey Locust. 

Spine.—A sharp, rigid termination of a branch as in the Honey Locust. A thorn. 

Honey locusts are deciduous trees with alternate, fine-textured leaves. They cast dappled shade and, except for their thominess and messy pods, are excellent as specimen or street trees. Thornless, nonfruiting cultivars are preferable. Gleditsia triacanthos van inermis is thorniest honey locust, from which most cultivars hkve been selected for landscape use. 

Set out in spring or fall as bare-root or balled-and-burlapped plants. Honey locusts are undemanding and are well-suited to city conditions. While they prefer moist, fertile, slightly alkaline soil, they tolerate drought and salt.

Faboideae (lucerne, fenugreek),where Gal substitution is nearly complete no steric inhibition would be encountered. In seeds of the Caesalpinioideae (carob, honey locust, Leucaena, Senna) the degree of reduction of substitution and the distribution of substituents would depend on the level of steric interaction.

A further set of aromatic glycosides to have been encountered (from the honey locust), and synthesized, are 6-sulphates of D-glucosides or D-allosides, e. g., (ilO). ... 

An example of the third type (novel pathway) is the production of ery A o-4-methylglutamic acid (9) from L-leucine (10) in Gleditisia triacanthos (honey locust, Fabaceae) and not from glutamic acid and SAM or from lysine as in many other plants (Fig. 13.4). 

Methylglutamic acid (9), (25, 45)-4-hydroxy-4-meth-ylglutamic acid (70) and 4-methyleneglutamic acid (26) apparently are derived from leucine (Fig. 13.14) (Rosenthal, 1982). All these compounds are found in honey locust, Gleditsia triacanthos (Fabaceae). 4-Methyleneglutamic acid (26) is also stored in the peanut, Arachis hypogaea (Fabaceae).
