Biological Nitrification

Australian native species grow competitively in nutrient limited environments, particularly in nitrogen (N) limited soils; however, the mechanism that enables this is poorly understood. Biological nitrification inhibition (BNI), which is the release of root exudates into the plant rhizosphere to inhibit the nitrification process, is a hypothesized adaptive mechanism for maximizing N uptake. To date, few studies have investigated the temporal pattern and components of root exudates by Australian native plant species for BNI. This study examined root exudates from two Australian native species,Hibiscus splendensandSolanum echinatum,and contrasted with exudates ofSorghum bicolor, a plant widely demonstrated to exhibit BNI capacity. Root exudates were collected from plants at two, four, and six weeks after transplanting to solution culture. Root exudates contained three types of organic acids (OAs), oxalic, citric and succinic acids, regardless of the species. However, the two Australian natives species released larger amount of OAs in earlier development stages thanS. bicolor. The total quantity of these OAs released per unit root dry mass was also seven-ten times greater for Australian native plant species compared toS. bicolor. The root exudates significantly inhibited nitrification activity over six weeks’ growth in a potential nitrification assay, withS. echinatum(ca. 81% inhibition) >S. bicolor(ca. 80% inhibition) >H. splendens(ca. 78% inhibition). The narrow range of BNI capacity in the study plants limited the determination of a relationship between OAs and BNI; however, a lack of correlation between individual OAs and inhibition of nitrification suggests OAs may not directly contribute to BNI. These results indicate that Australian native species generate a strongly N conserving environment within the rhizosphere up to six weeks after germination, establishing a competitive advantage in severely N limited environments.

Supernumerary B chromosomes represent one of many causes of numerical chromosome variation that exist in higher plants and animals. Sequences of DNA unique to B chromosomes of Brachycome dichromosomatica were enriched prior to cloning and resultant clones hybridizing only to plants containing B chromosomes were further investigated. Sequences of DNA that were characterised include members of a family of 176-bp tandem repeats that are specific to the B chromosomes of B. dichromosomatica, an annual Australian native plant species with only two pairs of A chromosomes and up to three dispensable B chromosomes. Sequence analysis of these six related clones indicated that some regions of the sequence are more highly conserved than others or, alternatively, that some adenine residues at the NdeII site are methylated. The repeat is homologous to DNA from Brachycome ciliaris var. languinosa but not to DNA from other related taxa growing in the vicinity of the B. dichromosomatica populations.Key words: plant DNA, B chromosomes, Brachycome dichromosomatica, molecular clones, repeated sequences.
