“…All these varieties are photoperiod insensitive and earlyflowering. The BKOS plant has deep purple seed coat, purplish red collar, auricles, ligules and leaf sheath, and dark purple stripes on the leaf blade (Phanchaisri et al, 2007). A previous study found the presence of anthocyanin in purple-coloured tissues of BKOS rice with significantly higher levels than those of KDML105 .…”

Thai jasmine rice (Oryza sativa L. cv. KDML105) is highly valued due to its subtle aroma, robust seed characteristics and high nutritional quality. Lowenergy ion-beam bombardment was chosen to improve the quality of jasmine rice by mutation induction. One mutated variety, named BKOS, was found to exhibit a deep purple colour due to an increased accumulation of anthocyanin. The total phenolic content and antioxidant activities of cooked and uncooked rice extracts were compared with KDML105, BKOS and other rice mutants created by a low-energy ion beam. The BKOS extracts showed the highest total phenol content (0.140 and 0.096 mg of gallic acid equivalent (GAE) g À1 dry extract from uncooked and cooked rice, respectively). The BKOS extracts also had improved antioxidant activities, determined using three standard methods: 2,2 0 -diphenyl-1-picrylhdrazyl (DPPH) free radical scavenging, ABTS radical cation (ABTS . þ ) decolourisation and ferric-reducing antioxidant power assays. BKOS extracts showed 2-2.5-fold increased levels for each method. Interestingly, there was no significant difference between the antioxidant activities of the cooked and uncooked BKOS rice extracts. The increased quantity of antioxidants in this anthocyanin-based natural product could allow antioxidants to be consumed by a wider population than what is currently possible.

“…Two varieties of local rice (Oryza sativa indica), purple glutinous rice (Kum Doi Saket) and Thai jasmine rice (KDML 105), were chosen for the mutation induction purpose [15,16]. Thousands of seeds of the rice were implanted with nitrogen ions at energy of 30 -60 keV to fluences of an order of 10 16 ions/cm 2 and mutants were selected from grown plants of the seeds.…”

$ Both authors contributed equallyIon beam at energy lower than tens of keV has been found to have significant biological effects on living materials. The finding has led to applications of ion-beam induced mutation and gene transfer. From the theoretical point of view, the low-energy ion beam effects on biology are difficult to understand with the knowledge of high-energy ion irradiation of biological matter since the ion range is so short that the ions can hardly directly interact with the key biological molecules for the changes. This paper introduces interesting aspects of low-energy ion beam biology, including basis of ion beam biotechnology and recent developments achieved in Chiang Mai University in relevant applications such as mutation and gene transfer and investigation on mechanisms involved in the low-energy ion interaction with biological matter such as eV-keV ion beam bombardments of naked DNA and the cell envelopes.

“…Thai jasmine rice seeds bombarded with nitrogen ions revealed one of new rice varieties, named BKOS6 rice, showing short stature (at 49 cm of the M1 plant height in culm length on the harvest day), photoperiod insensitivity, early flowering and accumulation of purple pigment in various tissues [1]. This variety showed mutational stability in all characteristics when observed in M1-M8 cultivations [2].…”

The potential of SCAR marker for discrimination of a Thai jasmine rice (Oryza sativa L. cv. KDML 105) mutant, BKOS6, obtained from ion-beam-induced mutation, was evaluated. The improved rice variety, BKOS6, exhibited many remarkable characteristics which fitted the multiple cropping system characteristics of progressive agriculture including photoperiod insensitivity, early flowering, short in stature, and purple pigment accumulation in pericarp. The BKOS6 rice grain extract has already been proved that it exhibited higher antioxidant properties than the KDML 105 and other tested rice grain extracts. In this study, the BKOS6 specific SCAR marker was developed by HAT-RAPD analysis of rice genomic DNA. The marker was successfully used to identify BKOS6 variety and its hybrid varieties containing purple pigment accumulation in plant tissues. Moreover, it was found that this marker could be used to detect other purple pigmented rice varieties that genetically related to Thai jasmine rice. Recently, a wide variety of anthocyanin-based foods are believed to provide significant potential health benefits, and become more attractive. KDML 105 is also a Thai premier fragrant rice variety which is one of the main varieties of country's rice export. Thus this molecular marker could be useful for commercial and breeding purposes of BKOS6 mutant and other developed varieties from KDML 105 which contain anthocyanin accumulation.
