“…Leucaenas contain a rare amino acid mimosine ([S]-f1-[N-(3-hydroxy-4-pyridone)]-a-aminopropanoic acid) that occurs elsewhere in only a few Mimosa spp. (Krauss and Reinbothe, 1973). Most species shed pollen as monads but three produce loosely fused compound grains and one produces 16-grain polyads (Guinet, 1966).…”

Leucaenas are fast‐growing neotropical trees and shrubs used as forage and fuelwood. This study tested the seed crosscompatibilities among 15 of the 16 well‐defined species of the paleopolyploid genus Leucaena Bentham (Leguminosae: Mimosoideae) to determine if genes of interest could be transferred between species. Twelve diploid and four tetraploid taxa were artificially hybridized in 118 of all 120 possible two‐way combinations and 31 of 32 possible self‐ and intraspecific matings, with 58,218 floret pollinations. Ninety‐one combinations (77%) produced well‐filled seed, and 73 of these combinations were grown and validated in the field. The qualitative crossability within ploidy levels (diploid, triploid, tetraploid) was 78%, 75%, and 100%, respectively, whereas quantitative crossability (relative to intraspecific matings) of successful matings within identical ploidy levels was 32%, 11%, and 73%, respectively. One‐third (34%) of the 114 interspecific combinations tested in both directions exhibited weak unilateral incompatibility (UI), due, in part, to reciprocal differences in stylar length. Other mechanisms for UI (embryo‐endosperm imbalance, sex‐specific use of self‐compatible parents) were ruled out. Wide hybridization appears to be “buffered” by polyploidy in the genus.

“…All contained pipecolic acid (58), trans-5hydroxypipecolic acid and one or more isomers of 3-hydroxy-4-methylglutamic acid (67). A broad survey of 104 species belonging to 40 genera of the Mimosoideae showed that the seeds of this subfamily were rich in non-protein amino acids, some of which had not been found elsewhere [83]. The distribution patterns reflected specific features of the tribes and genera within the subfamily.…”

The non-protein amino acids, with which we are concerned here, are not incorporated into the proteins of the organisms that synthesize them nor are their residues formed by the post-translational modification of protein amino acid residues. Nonprotein amino acids are of value in the study of relationships between species and higher taxa of organisms because most of them are of restricted distribution. If a particular non-protein amino acid is only known to occur in a limited group of species which are related in other respects then it is probable that these species have all arisen from a common ancestral form in which the biosynthetic pathway to that particular non-protein amino acid already existed.

The use of plants with therapeutic properties is as ancient as human civilization. Acacia modesta belongs to family Fabaceae and is a deciduous tree which has medium or small size. Traditionally, it has been used to treat leprosy, wounds, dysentery, venereal diseases, cough, body weakness, bacterial infections and backache. Many pharmacological activities have been reported viz. antibacterial, antifungal, anti-hyperglycemic, analgesic, anti-inflammatory, anti-platelet, anti-termite, antioxidant, brine shrimp cytotoxicity, haemagglutination, insecticidal, phytotoxic and spasmolytic. While various flavonoids, terpenoids, alkaloids, tannins, non-protein amino acids, fixed oils and cyclitols have been isolated from this plant. This review is an attempt to provide adequate information on ethno-medicinal uses, general morphology, pharmacological and phytochemical properties of the plant.
