  • 1 September 1998
TLDR
Seed anatomy and micromorphological, wood anatomical, and floral morphological characters indicate that the taxa investigated form a monophyletic group close toMalvales s.
Plants Attract Parasitic Wasps to Defend Themselves against Insect Pests by Releasing Hexenol
TLDR
It is shown that plants can effectively pull wasps towards them by releasing a universally induced compound, (Z)-3-hexenol, and potentially keep these plants safe from parasitic assaults by leafminer pests, L. huidobrensis, and suggests that, as the most passive scenario of plant involvement, leafminers and mechanical damages evoke similar semio-chemicals.

    Plant Systematics and Evolution
  • 1 March 1998
TLDR
The floral development of representatives of six genera ofCistaceae has been studied and the derivation of polyandry in Malvanae from diplo- or obdiplostemony is discussed by comparison with the sister clades ofMalvanae as shown in recentrbcL studies.
Evolution of Chlorophyll Degradation: The Significance of RCC Reductase
TLDR
RCCR appears to represent a decisive addition to the catabolic pathway: it allows terrestrial plants to metabolize the porphyrin part of the chlorophyll molecule to photodynamically inactive final products that are stored in the vacuoles of senescing mesophyll cells.
Chemical Characterization of Magnolia Biondii (Flos Magnoliae, Xin Yi)
TLDR
A rapid TLC-method for the identification of plant material from Magnolia biondii and its distinction from M. denudata and M. liliiflora was developed and eight tetrahydrofurofuran lignans and sesquiterpene lactone parthenolide were found in flower buds.
Evidence for the monophyletic evolution of benzylisoquinoline alkaloid biosynthesis in angiosperms.
TLDR
Phylogenetic analysis of NCS, berberine bridge enzyme and several O-methyltransferases suggest a latent molecular fingerprint for BIA biosynthesis in angiosperms not known to accumulate such alkaloids, which support the monophyletic origin of Bia biosynthesis prior to the emergence of the eudicots.
Two Novel Spirostene Glycosides from Selaginella chrysocaulos and their Chemotaxonomic Significance.
TLDR
During an investigation of the Indian heterosporous fern Selaginella chrysocaulos, two novel C28 spirostene monoside monosides were identified and the taxonomic significance of the occurrence ofSpirostenes in the group of Lycophyta is discussed.
