Doyle (1991, 2000), Frohlich and Parker (2000), Friedman and Floyd (2001), G. The evo-devo research perspective could help us decipher more than 400 million years of insect and seed plant evolution and the enigmatic origins of flowering plants and interacting Holometabola. (2014), and Tomescu (2016), among others, are useful in understanding the developmental systems of animals, fungi, and plants. Several neurosecretory hormones play an important part in mechanisms that regulate cell division and growth including insulin-like peptides (Drosophila insulin-like proteins [DILPs] and bombyxins), chitenase-derived imaginal disk factor proteins, the steroid hormone ecdysone, local autocrine and paracrine TFs, and brain neurosecretory prothoracicotropic hormone (PTTH) (Nijhout 2003).

Evolutionary-development of arthropod- and plant organs and molecular tool kits is "highly dynamic in evolutionary time" involving the evolution of cis-acting promoters (page 83, Baum 1998). Reviews by Rothwell (1987), Arthur (2002), Meyerowitz (2002), Becker and Theißen (Figure 1, page 468, 2003), Niklas (2006), Rothwell et al. A key paper on the control of insect body size by Nijhout (2003) outlines the molecular mechanisms involving cis-acting TFs and hormones and environmental controls (nutrition and temperature) behind growth and cell division in hemimetabolous and holometabolous insects.

Ontogeny is thus the creative force behind botanical diversification, and small modifications at the genetic level may have a disproportionate effect on plant form as their consequences cascade and multiply through development. Kenrick (1997), Diverted development of reproductive organs: a source of morphological innovation in land plants, Plant Systematics and Evolution 206: 161-174. From the research perspectives of insect- and floral biology, and paleoentomology and floral morphology, scaling data might be applied to understanding and computing theoretical morphospace of whole invertebrate and/or plant organs (Jeune et al. Prothoracicotropic hormone and/or ecdysone secretion in Holometabola is negatively controlled by juvenile hormone (JH) (Truman and Riddiford 2002).

Dilcher from the Lower Cretaceous Dakota Formation of North America. Tropical forests of the larger islands yield ten genera of monocotyledonous palms including the monotypic Alsmithia longipes, and the enigmatic magnoliid flowering plant family, Degeneriaceae. Historical Context: Many bibliographies on angiosperm floral diversity and the origin and evolution of flowering plants are available. Labandeira (2010) states: The aforementioned passage is from page 471 of C. Labandeira (2010), The pollination of mid-Mesozoic seed plants and the early history of long-proboscid insects, Annals of the Missouri Botanical Garden 97(4): 469-513. Ancient insect wings probably functioned as respiratory organs. Molecular model systems used as tools in beetle genomic research and phylogenetic studies include proteins central to development (JH esterases), diapause proteins, heat shock proteins, ultraspiracle (an ecdysone nuclear receptor protein), cuticle proteins, hexamerins, genes encoding vitellogenin, and apolipophorins, among others (see review by Gómez-Zurita and Galián 2005). Neues Jahrbuch für Geologie und Paläontologie Abhandlungen 268(1): 65-82.

The International Journal of Plant Sciences devotes most of Number 7 of Volume 169 (2008) toward the ongoing search for the earliest flowers, based on an international symposium held during the summer of 2007 at the Swedish Museum of Natural History (von Balthazar et al. More than twenty articles in Volume 96, Number 1 of the American Journal of Botany explore the origin, evolution, and radiation of flowering plants to celebrate the Charles Darwin Bicentennial (Stockey et al. Conrad Labandeira's several reviews on fossil insect-plant phytophagous associations (Labandeira 2000, 2006, 2007 [two papers], 2010, 2014) contain extensive bibliographies. 2008) and assembly of chitin and cuticle proteins into the exoskeleton (Charles 2010, Moussian 2010). Another Hox protein Abd-B, when combined with the Dsx enzyme, represses expression of the wg gene in fruit flies (W. I also add hexamerin moulting storage proteins which are related to hemocyanin respiratory enzymes (Burmester et al. 2006, Burmester and Hankein 2007), JH esterases, vitellogenin genes and yolk proteins (Isoe and Hagedorn 2007), pheromone chemoreceptors (Robertson and Wanner 2006), and certain nuclear receptor proteins (Bonneton et al. 2008) including ultraspiracle, and ecdysone inducible TFs to the list of molecular developmental tools among early diverging arthropod lineages. The first appearance of insect wings in the rock record of the Paleozoic Era has yet to be established.

Arthropod body allometry is intertwined with development of larval and imaginal disc tissues (Stern and Emlen 1999, Shingleton et al. 1997), Ubx (Pavlopoulos and Akam 2011), and the field-specific selector gene necessary for limb development in Drosophila (Diptera) known as dll (S. Fushi-tarazu protein encoded by the ftz gene, intracellular tertiary enzyme structure folding environments, and the apparent flexibility of Ftz and other Hox proteins in the evolution of arthropods, are discussed in a recent review by Merebet and Hudry (2011). These studies, among others underway or already published by Sean Carroll and colleagues, underscore the importance of Hox proteins in evolution of the arthropod tool kit. Mesozoic paleogeography and early angiosperm history.

The image above is the northwestern face of the Korombasabasaga Range, Viti Levu Island, Fiji as viewed from the road between Namosi and Wainimakutu villages. A review of neotenous development in termites is available (Korb and Hartfelder 2008). Structurally similar to bioactive plant brassinosteroids, 20E-ecdysone induces a cascade of TF biosynthesis important in the regulation of insect development (Truman and Riddiford 2002, De Loof 2008). One line of paleobiological thinking hypothesizes that insects took flight to exploit new habitat. Did ingestion of seed plant brassinosteroids by pterygote insects affect the evo-devo of wings from thoracic limb pads and JH signaling?

The evo-devo of insect caste polyphenism is reviewed by Emlen and Nijhout (2000). Thummel and Chory (2002) point to a possible coevolutionary connection between the 20E-ecdysone/cytochrome P biosynthetic machinery of insect antagonists and seed plant hosts. Further, changes in the arthropod homeodomain and evolution of new protein motifs led to new Hox developmental tool kit functions in certain insect lineages (S. The paleobiology of insect flight in relation to the advent of arthropod-seed plant mutualisms remains unexplained.

The paleobiology of insect flight in relation to the advent of arthropod-seed plant mutualisms remains unexplained. Could paleoecologists benefit by studying experimental, 3-D printed artificial constructs of shoots and protoflowers in theoretical morphospace? By measuring and scaling detached and shed foliar and cone- floral-organs, and by combining these data with studies of permineralizations, "fingerprints of developmental regulation" (quoted from page 723, Sanders et al.
