• Xanthomonas oryzae pv. oryzae (Xoo), a causal agent of bacterial leaf blight (BLB), is one of the most important pathogens of rice. The effectiveness of ten Streptomyces spp. isolates in suppressing Xoo disease was assessed in planta and in vitro. In planta experiments were carried out in a greenhouse and arranged in a randomized completely block design (RCBD) with three replications. Twenty treatments were tested which included plants inoculated with both Streptomyces spp. and Xoo, and plants inoculated with only Streptomyces spp. Plants inoculated with Xoo and sprayed with a chemical bactericide, and plants inoculated with only Xoo served as positive controls, whereas plants not inoculated with either Streptomyces spp. or Xoo were used as negative controls. The results showed that the effect of endophytic Streptomyces spp. on BLB disease expressed as area under disease progress curve (AUDPC) was not significantly different to that on control plants (P > 0.05). However, plants inoculated with endophytic Streptomyces spp. were significantly taller and produced higher tiller number than control plants (P < 0.05). Streptomyces spp. isolate AB131-1 gave the highest plant height. In vitro studies on biocontrol mechanisms of selected Streptomyces spp. isolates showed that isolate LBR02 gave the highest inhibition activity on Xoo growth, followed by AB131-1 and AB131-2. Two isolates (AB131-1 and LBR02) were able to produce chitinase, phosphatase, and siderophore which included biocontrol characteristics. Morphological and colonization studies under SEM and light microscopy confirmed that the three isolates were endophytic Streptomyces spp. from different species. These studies found that the paddy plant which was inoculated with endophytic Streptomyces spp. AB131-1 and infected by Xoo could increase the height of plant and number of tillers

• Boronia heterophylla is cultivated for cut flower production. Three cultivars dominate production, ‘Red’, ‘Cameo’, and ‘Moonglow’. A variety of colors and an extended flowering period are demanded by local and overseas markets. The aim of this study was to develop procedures for a Boronia heterophylla breeding program through intraspesific hybridization. This may yield progeny with desirable characteristics, ideally increased vigor, and a range of flower colors and flowering times. Nine pollination combinations were attempted, each self pollination and all reciprocal crosses. Seed set varied from 17 to 95%. Embryo rescue (was employed to produce hybrid plants using half strength Murashige and Skoog (MS) basal media and it was most successful (75%) 5-6 weeks after pollination. All shoots multiplied on media containing MS salts + NAA (0.1 mg/l) + BA (0.4 mg/l). All shoots transferred to medium containing half strength MS salts + NAA (4 mg/l) produced roots. Plantlets were acclimatized to sterile potting mix (in a small chamber within a glass house. This intraspecific hybridization system was very successful and plants were obtained for all pollination treatments except for selfed ‘Moonglow’. Embryo rescue may provide a system for germinating other species with difficult to germinate or dormant seed
