“…For example, data from the chloroplast orf2280 gene places Sarcobatus (allied with the Chenopodiaceae, but possessing globular sieve element plastid inclusions, Behnke, 1994) near the Phytolaccaceae (Downie et al, 1995). A phylogeny from a nuclear-encoded gene would be valuable since the relationship of the Caryophyllaceae with the Chenopodiaceae and Amaranthaceae suggested by chloroplast DNA data is hard to reconcile with Chang and Mabry's (1974) RNA-DNA hybridization data, which shows Caryophyllaceae 16 S ribosomal RNA as highly divergent from that of spinach. The accumulation of gene sequence data may also lead to a confident placing of the "root" for the order.…”

While the apparent mutual exclusiveness of anthocyanins and betalains in the Caryophyllales has given rise to considerable taxonomic debate, historical factors affecting the present distribution of these compounds have rarely been discussed. An understanding of pigment evolution in the order is hindered by a number of unresolved systematic issues and a lack of knowledge of the importance of anthocyanins and betalains beyond their roles in pollination and seed dispersal. The hypothesis that betalains arose in an unpigmented ancestor of the Chenopodiinae in response to selection from pollinators cannot be rejected, but scant evidence exists in favor of it. Questions persist regarding whether the most recent ancestor to the Chenopodiinae presented a pigmented floral display and whether the appropriate pollinators were present at this time to select for floral pigmentation. In view of these ambiguities and the possible non-monophyly of the Chenopodiinae we consider some alternative scenarios and suggest potentially rewarding avenues for future research. We discuss roles for anthocyanins and betalains beyond their use as optical attractants, possible costs and benefits associated with producing each pigment type, and the possibility that they may have cooccurred in an ancestor for some period of time.

“…Rodman et al noted that their phylogeny "gains significant support" from several external data sources. For example, they favorably compared the order of families in Chang and Mabry's (1973) nucleotide homology scale (Chenopodiaceae > Amaranthaceae > Phytolaccaceae > Portulacaceae > Nyctaginaceae> Caryophyllaceae) with the patristic distances of these families from Chenopodiaceae in the Rodman et a!. cladogram.…”

“…It now appears that the 4,5-extra chol cleavage of L-dopa (Fig. 3) can lead to betalamic acid (Fischer & Dreiding, 1972;Impellizzeri & Piattelli, 1972;Chang et al, 1974) in the Centrospermae and the mushrooms (Musso, private communication) and to stizolobic acid in the antliocyanin-containing Leguminosae (Ellis, 1976) and also mushrooms (Saito et ah, 1975(Saito et ah, , 1976Musso, private communication). Yet the conversion of the cleaved product to betalamic acid and its conversion into other betalains is known for the Centrospermae and mushrooms only.…”

Perliaps no other order of flowering plants of its size is as well investigated morphologically, nltrastructurally, and chemically as is the Centrospennae. Tlie betalain pigment discoveries of the early 1960s were followed by the moie recent discovery of nni^ine protein depositions in the sieve-element plastids of members of this order. These and otlier molecular data, including DNA-RNA hybridization results, have permitted a circumscription of the order based on 11 core families, including all 9 betalain families: Aizoaceae, Amaranthaceae, Basellaceae, Cactaceae, Chenopodiaceae, Didiereaceae, Nyctaginaceae, Phytolaccaceae, and Portulacaceae, as well as two anthocyanin families: Caryophyllaceae and Molluginaceae. Several smaller betalain taxa (including Giaekia, lialoplnjtum^ Hectorella, and Dtjsphania) which are sometimes treated as independent families or as members of one of these 11 core families also clearly belong to the order. Other families such as the Bataceae, G>'rostemonaceae, Vivaniaceae, and Thchgonaceae are excluded from the Centrospermae. The betalain evolutionary line of centrospermous families may have originated from a centrospermous ancestor which lost the ability to produce anthocyanins and then subsequently gained the two or three steps required to produce betalains. Pollen morphology of centrospermous taxa and the widespread occiirrence of Cj photosynthesis in the Centrospermae are also discussed.Since all the review papers from a symposium on the "Evolution of Centrospermous Families/' presented in July, 1975 during the Xllth International Botanical Congress, Leningrad, USSR, have now been published (Mabry & Behnkc, 1976a), a summary of our current views of the Centrospemiac (or Caryophyllales) will suffice in this review. This account will emphasize the way our interpretations of the order have been shaped by molecular data.Since 1876 when Eichler (see Table 1) introduced the name for tlie order, the Centrospermae have always contained a core of about 8-12 famihes. Eichler (1876 and, in part, 1878) recognized most of what we now consider to be centrospermous families including, for example, the Cactaceae (in the 1876 treatment).In the 100 years following Eichler's work, most systematists also included those families now generally recognized on the basis of molecular data as belonging to the order but often included additional ones (compare Tables 2, 3 and 4). The molecular data which bear upon our current treatment of the order are suiumarized in the following sections. Sieve-element PLAsxmsOf all the modern approaches for investigating the Centrospermae, none has, in my opinion, contributed more to our understanding of the circumscription of the order than the ultrastructural investigations of the sieve-element plastids.
