Evolution of Leaf Morphogenesis: Evidence from Developmental and Phylogenetic Data in Papaveraceae
Variation of leaf morphology in Papaveraceae s.l. (including Fumariaceae and Pteridophyllum) has previously been shown to be related to developmental differences in the direction of segmentation and in blade-petiole differentiation. Based on ontogenetic comparisons, we here distinguish polyternate, acropetal, basipetal-pedate, basipetal-pinnate, and divergent modes of dissection. In addition, u...
متن کاملEvolution of perianth and stamen characteristics with respect to floral symmetry in Ranunculales.
BACKGROUND AND AIMS Floral symmetry presents two main states in angiosperms, namely polysymmetry and monosymmetry. Monosymmetry is thought to have evolved several times independently from polysymmetry, possibly in co-adaptation with specialized pollinators. Monosymmetry commonly refers to the perianth, even though associated androecium modifications have been reported. The evolution of perianth...
متن کاملNew Product Development in the Pharmaceutical Industry: Evidence from Iran
In today’s competitive world, there are several strategies to deal with the fast changing environment, among which New product development (NPD) is a common strategy. However, almost half of the resources that companies devote to NPD are spent on products that may fail. This issue is particularly highlighted in the pharmaceutical industry mainly because of a long development-time, low success r...

متن کاملAn expanded age range for meningococcal meningitis: molecular diagnostic evidence from population-based surveillance in Asia
BACKGROUND To understand epidemiologic patterns of meningococcal disease in Asia, we performed a retrospective molecular analysis of cerebrospinal fluid (CSF) specimens collected in prospective surveillance among children aged < 5 years of age in China, South Korea, and Vietnam. METHODS A total of 295 isolates and 2,302 CSFs were tested by a meningococcal species- and serogroup-specific polym...
