Abstract:
Extrafloral nectaries (EFNs) are of ecological, evolutionary and taxonomic importance in many plants, but are often overlooked in botanical descriptions and have rarely been studied in humid Australian forests. We examined EFNs in a tropical rainforest in northern Queensland, Australia. A total of 29 plant species was found bearing EFNs within the 1-ha study plot at the Australian Canopy Crane Project and an additional 10 EFN species were found in rainforests and other habitats outside, but nearby, the plot. The records include 12 genera in which EFNs have not been previously reported (Ardisia, Bambusa, Castanospermum, Dysoxylum, Melicope, Flagellaria, Glochidion, Ichnocarpus, Merremia, Rockinghamia, Syzygium, Wrightia), including one new family (Flagellariaceae). In the study plot, 13 tree species (17% of tree species with dbh >10 cm), 10 climbing plant species (21%) and six shrubs had EFNs, a similar proportion compared with tropical forests on other continents. Morphology of most EFNs was studied by using scanning electron and light microscopy. Extrafloral nectaries were assigned to five different structural types (sensu Zimmermann 1932): flattened, elevated, pit, scale-like and formless nectaries. EFNs from all species were regularly visited by ants, allowing detection of many otherwise inconspicuous nectaries.

Abstract:
Castanospermine (CS) is an alkaloid isolated from the nut of the Australian chestnut tree, Castanospermum australae. It has been shown to have potent anti-inflammatory effects, as evidenced by its ability to inhibit the clinical manifestations of passively induced autoimmune encephalomyelitis and passive adjuvant arthritis in rats and the efferent phase of contact hypersensitivity in mice. The purpose of this study was to determine if CS has immunosuppressive, as well as anti-inflammatory, properties. Contact hypersensitivity in mice to picryl chloride was chosen as the in vitro model of cell mediated immune reactivity. Mice were sensitised with picryl chloride and treated with CS, at doses of 150 and 300 mg/kg/day, twice daily for seven days, beginning at the time of sensitisation. Passive transfer of spleen cells from treated animals transferred significantly less contact hypersensitivity (P<0.05) to naive mice than did cells from control mice. This suggests that CS inhibited the generation of picryl chloride reactive effector cells. This inhibition was not due to a depletion of the T cell phenotype responsible for contact hypersensitivity, CD4+, as FACS analysis showed no alteration in CD4+/CD8+ ratio in CS treated mice. In vitro studies, using antigen-specific cell lines, showed that CS inhibits antigen specific T-cell proliferation in a dose dependent fashion. Studies on the kinetics of this inhibition revealed that CS inhibits an early step, before 24 hours of culture have elapsed, in the T-cell proliferative response. Experiments were designed to examine if this early event was antigen processing by the accessory cells in the culture, or an early event in T-cell replication itself. CS not only failed to inhibit the antigen processing step, but when processing was carried out in the presence of CS the subsequent T-cell proliferation was enhanced. The results also indicated that CS, when added with preprocessed antigen, was inhibiting T-cell proliferation in a dose dependent manner. Subsequent studies examining the role of several key molecules in T-cell proliferation showed that CS did not effect the expression of the receptors for IL-2 or transferrin, nor did it alter the expression of the adhesion molecules LFA-1 or ICAM-1. The precise molecular mechanism by which CS inhibits contact hypersensitivity in vivo and T-cell proliferation in vitro still remains to be determined.

Abstract:
The present study was aimed to find out if there is any symbioses between C.australe roots and mycorrhizal fungi. This research also aimed to investigate the effect of Arbuscular mycorrhizal fungi on the growth of C.australe and the yield of alkaloid castanospermine. The rhizosphere soil and roots of C.australe from various sites in Sydney were collected. Roots were stained with vital and non-vital stains for assessment of mycorrhizal infection. The result indicated that AM fungi symbiotic associations with the roots of C.australe, producing arbuscules and vesicles in the root cortices. By wet sieving and decanting of rhizosphere soil, spores and sporocarps of AM fungi, were recovered. The spores mainly belonged to the genus Glomus. A correlation study was conducted to determine the relationship between the AM infection percentage in the roots and the Castanospermine amount in the leaves and seeds of the field grown trees. The results showed that there is a positive relationship between the castanospermine amount in the seeds and AM infection percentages in the roots. The effect of phosphorus on the yield of castanospermine was also investigated. The results indicated that phosphorus do enhance castanospermine at certain levels, but a further increase in phosphorus application resulted in reduced AM infection. It was found that AM has a great effect on the growth and production of C.australe and biosynthesis of castanospermine.

Delahaie, Julien. "Comparaison moléculaire des graines orthodoxes de Medicago truncatula et récalcitrantes de Castanospermum australe : une nouvelle approche pour comprendre l'acquisition de la tolérance à la dessiccation." Phd thesis, Université d'Angers, 2013. http://tel.archives-ouvertes.fr/tel-00961568.

Full text
Abstract:
La tolérance à la dessiccation (TD) est définie comme l'aptitude à survivre à l'état sec et à reprendre un métabolisme normal après le retour à des conditions hydriques favorables. Contrairement aux graines orthodoxes, qui acquièrent la TD au cours de leur maturation, les graines récalcitrantes ne survivent pas à la dessiccation. L'analyse comparative du développement de ces deux types de graines constitue donc un modèle intéressant pour mettre en évidence des mécanismes spécifiquement impliqués dans la TD. Par des approches protéomique et transcriptomique, ce travail a permis de caractériser le développement de graines récalcitrantes de Castanospermum australe et de le comparer à celui de graines orthodoxes de Medicago truncatula, espèce de la même sous-famille des Fabacées. Nos résultats montrent que certaines protéines de type LEA (Late Embryogenesis Abundant) sont absentes ou faiblement accumulées dans les graines matures de C. australe comparé à celles de M. truncatula. Le profil des LEA ressemble à celui du mutant Mtabi3, déficient pour le régulateur majeur de la maturation des graines orthodoxes ABI3 (ABscissic acid Insensitive 3). L'analyse transcriptomique révèle une forte répression de CaABI3 et de ses gènes cibles en fin de développement chez les graines de C. australe, alors qu'ils restent fortement exprimés tout au long de la maturation des graines de M. truncatula. Deux gènes codant pour ABI3 ont été clonés chez C. australe : CaABI3 et CaABI3-like. Par sur-expression ectopique dans des racines de M. truncatula, seul CaABI3-like est en mesure d'activer les mêmes cibles que MtABI3. De plus, CaABI3 ne complémente pas le mutant abi3-5 d'Arabidopsis thaliana. Cette analyse renforce l'importance d'ABI3 pour expliquer la sensibilité à la TD des graines récalcitrantes. Elle révèle par ailleurs que la graine mature de C. australe présente certaines caractéristiques d'une graine prête à germer tout en exprimant de nombreux gènes de réponse au stress.
