Hypoxidaceae
Hypoxidaceae is a family of flowering plants, placed in the order Asparagales of the monocots. The APG IV system of 2016 (unchanged from the 1998, 2003, and 2009 versions) recognizes this family. The family consists of five genera, with some 160 species. The members of the family are small to medium herbs, with grass-like leaves and an invisible stem, modified into a corm or a rhizome. The flowers are born on leafless shoots, also called scapes. The flowers are trimerous, radially symmetric. The ovary is inferior, developing into a capsule or a berry.

Curculigo
''Curculigo'' is a flowering plant genus in the family Hypoxidaceae, first described in 1788. It is widespread across tropical regions of Asia, Africa, Australia, and the Americas. Curculin is a sweet protein that was discovered and isolated in 1990 from the fruit of ''Curculigo latifolia'', a plant from Malaysia. Like miraculin, curculin exhibits taste-modifying activity; however, unlike miraculin, it also exhibits a sweet taste by itself. After consumption of curculin, water and sour solutions taste sweet. The plant is referred to locally as or ; English: 'weevil-wort'.

Curculigo Latifolia
''Curculigo latifolia'', also known as tambaka, lamba and lemba babi, is a species of flowering plant, a stemless perennial herb in the Hypoxidaceae family, that is native to Southeast Asia and produces edible fruits. Description The plant grows as a clump of 7–10 erect leaves, up to 1 m high in open areas and 2 m in forest shade. The leaves are 60–150 cm long by 8–25 cm wide. The inflorescences grow from the base of the leaves up 10 cm in height, forming compact 8 cm panicles of green bract In botany, a bract is a modified or specialized leaf, associated with a reproductive structure such as a flower, inflorescence axis or cone scale. Bracts are usually different from foliage leaves in size, color, shape or texture. They also lo ...s and yellow flowers. The fruits are oval berry (botany), berries, 2–3 cm by 1.2–1.7 cm in diameter, ripening white tinged pink, enclosing small black seeds in edible white pulp, with a taste ...

Curculin
Curculin or neoculin is a sweet protein complex that was discovered and isolated in 1990 from the fruit of '' Curculigo latifolia'' ( Hypoxidaceae). Like miraculin, curculin exhibits taste-modifying activity; however, unlike miraculin, it also exhibits a sweet taste by itself. After consumption of curculin, water and sour solutions taste sweet. mRNAs for a related protein complex is found in '' Curculigo capitulata'' fruits, though at a much lower level of expression – so low that the product is undetectable by immunoblotting. Protein structure The active form of curculin is a heterodimer consisting of two monomeric units connected through two disulfide bridges. The mature monomers each consist of a sequence of 114 amino acids, weighing 12.5 kDa (curculin 1) and 12.7 kDa (curculin 2), respectively. While each of the two isoforms is capable of forming a homodimer, these do not possess the sweet taste nor the taste-modifying activity of the heterodimeric form. To avoid c ...

APG III System
The APG III system of flowering plant classification is the third version of a modern, mostly molecular-based, system of plant taxonomy being developed by the Angiosperm Phylogeny Group (APG). Published in 2009, it was superseded in 2016 by a further revision, the APG IV system. Along with the publication outlining the new system, there were two accompanying publications in the same issue of the Botanical Journal of the Linnean Society: * The first, by Chase & Reveal, was a formal phylogenetic classification of all land plants (embryophytes), compatible with the APG III classification. As the APG have chosen to eschew ranks above order, this paper was meant to fit the system into the existing Linnaean hierarchy for those that prefer such a classification. The result was that all land plants were placed in the class Equisetopsida, which was then divided into 16 subclasses and a multitude of superorders. * The second, by Haston ''et al.'', was a linear sequence of families fol ...

APG System
The APG system (Angiosperm Phylogeny Group system) of plant classification is the first version of a modern, mostly molecular-based, system of plant taxonomy. Published in 1998 by the Angiosperm Phylogeny Group, it was replaced by the improved APG II in 2003, APG III system in 2009 and APG IV system in 2016. History The original APG system is unusual in being based, not on total evidence, but on the cladistic analysis of the DNA sequences of three genes, two chloroplast genes and one gene coding for ribosomes. Although based on molecular evidence only, its constituent groups prove to be supported by other evidence as well, for example pollen morphology supports the split between the eudicots and the rest of the former dicotyledons. The system is rather controversial in its decisions at the family level, splitting a number of long-established families and submerging some other families. It also is unusual in not using botanical names above the level of order, that is, an ...

APG IV System
The APG IV system of flowering plant classification is the fourth version of a modern, mostly molecular-based, system of plant taxonomy for flowering plants (angiosperms) being developed by the Angiosperm Phylogeny Group (APG). It was published in 2016, seven years after its predecessor the APG III system was published in 2009, and 18 years after the first APG system was published in 1998. In 2009, a linear arrangement of the system was published separately; the APG IV paper includes such an arrangement, cross-referenced to the 2009 one. Compared to the APG III system, the APG IV system recognizes five new orders ( Boraginales, Dilleniales, Icacinales, Metteniusales and Vahliales), along with some new families, making a total of 64 angiosperm orders and 416 families. In general, the authors describe their philosophy as "conservative", based on making changes from APG III only where "a well-supported need" has been demonstrated. This has sometimes resulted in placements th ...
