A comparative analysis of plastome evolution in autotrophic Piperales
American Journal of BotanyAbstractPremiseMany plastomes of autotrophic Piperales have been reported to date, describing a variety of differences. Most studies focused only on a few species or a single genus, and extensive, comparative analyses have not been done. Here, we reviewed publicly available plastome reconstructions for autotrophic Piperales, reanalyzed publicly ...

Morphological and developmental evidence is utilized in a phylogenetic analysis of Piperales. Best resolution of trees was obtained by combining ontogenetic data with conventional morphological data. Floral ontogeny provides a means to determine homology among character states as well as to provide additional characters not observable in mature flowers.

Xanthaciura (Tephritidae, Tephritinae) is a Neotropical genus composed of 17 species. Currently, to Brazil are recorded eight valid species names. The members of the Tephritinae are marked by their interaction with Asteraceae, as females lay eggs in the plant, where the larvae posteriorly feed and develop on various parts of the plant as capitulum ...

Abstract Flowers of most Piperales do not reward pollinators. However, a few mutualistic pollination relationships have been proposed among the perianth-bearing species. To test the hypothesis of a mutualistic relationship between Prosopanche and beetle pollinators, we studied the pollination biology of three species (P.

The vast majority of flowering plant seeds contain a triploid endosperm formed by fertilization of a monosporic, Polygonum‐type female gametophyte. However, evolutionary transitions to six other genetic constructs of endosperm are widespread, and six of seven known patterns are found in the order Piperales.

The current strong interest in the group of taxa known as “paleoherbs” (Donoghue and Doyle, 1989) results from their aggregation at the base of the angiosperms based on morphological evidence (Donoghue and Doyle, 1989a, Donoghue and Doyle, 1989b) and molecular evidence (Zimmer et al., 1989; Hamby, 1990; Hamby and Zimmer, 1992; Chase et al., 1993).

Piperales represent the largest basal angiosperm order with a nearly worldwide distribution. The order includes three species rich genera, Piper (ca. 2000 species), Peperomia (ca. 1500-1700 species), and Aristolochia s. l. (ca. 500 species). Sequences of the matK gene and the non-coding trnK group II intron are analysed for a dense set of 105 taxa ...

Comparison of vegetative anatomy of Piperales. II. Leaf.
Acta biologica Academiae Scientiarum Hungaricae, 1978Many characters of leaf (hair, hypodermal cells, palisade layers, intercellular space, distinction between spongy and palisade parenchyma, "palisade ratio", distribution of collenchyma and sclerenchyma, presence or absence of starch grains, calcium oxalate crystals, number, shape and arrangement of bundles of petiole) are useful distinguishing ...

AbstractThe essential oil (EO) ofPiper aduncumLinnaeus, known as ‘sireh lada’ to locals Malaysian, has the potential to be used as an alternative to synthetic insect repellents such as N,N-diethyl-meta-toluamide. However, the EO's efficacy as a repellent decreases after application due to the high volatility of its active ingredients.

Floral identity MADS‐box A, B, C, D, E, and AGL6 class genes are predominantly single copy in Magnoliids, and predate the whole genome duplication (WGD) events in monocots and eudicots. By comparison with the model species Arabidopsis thaliana, the expression patterns of B‐, C‐, and D‐class genes in stamen, carpel, and ovules are conserved in ...
