Item type:Publication, Enhancement of plant regeneration efficiency from mature grains of thai indica rice (Oryza sativa L. cv. KDML105)(2012-08-01); In vitro protocol for efficient plant regeneration has been developed from Thai indica rice cultivar (Oryza sativa L. cv. KDML105). Embryogenic callus was initiated from mature seeds on NBMI medium. The highest frequency (96.00%) of callus induction was obtained on NBMI1 medium [2 mg L-1 2,4-dichlorophenoxyacetic acid (2,4-D) without kinetin]. These calli were sub-cultured on NBM medium supplemented with various concentrations of BA or combination with supporting materials for plant regeneration. Plant regeneration from embryogenic callus was increased in the medium supplemented with 5 g L-1 Phytagel® in the regeneration medium (NBMR9 medium; 30.00%). In addition, the best regenerated frequency in this experiment was obtained by culturing the embryogenic callus to 4:4 ratios of Gro-lux tubes to fluorescent light tubes at 1000 lux light intensity (56.72%). The regenerated plants were successfully transplanted to soil. The results indicated that manipulation of medium supplements and the cultured condition leads to increase plant regeneration efficiency in KDML105 cultivar for genetic transformation in the future. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Tobacco randomly inserted TT8 differenly enhance light signals and flavonoid accumulation(2015-08-18); Kanthang, SuphaThe individual lines of tobacco over-expressing TT8, a bHLH gene, were constructed and cultured under tissue culture condition radiating with photosynthetically activation radiation (PAR) or PAR+UVA. They were compared to wild type (WT). Leaf of treated plants was extracted and analyzed for flavonoid accumulations using a spectrophotometer. The extract of TT8 plants significantly contained flavone, flavonol and anthocyanin level, higher than the WT extract did. The petal extracts of mature transgenic under PAR had a similar absorbance profile of each substance, but these extracts had higher flavonoid contents than the leaf extracts did. All flavonoid subgroups and p-coumaric acid biosynthesis were significantly enhanced after the additional UVA radiation to plant. This UVA condition slightly stimulated an accumulation of these substances in normal plant. Some transgenic greatly increased flavonoid accumulation in responding to PAR+UVA, but the others were slightly different compared to WT. The distinct insertion site is directly affected TT8 gene expression. Transgenic seeds had a dark brown color more than WT seed, which indicated high content of polymer flavonoids (proanthocyanins). This over-expressing TT8 in transgenic tobacco may directly or indirectly enhance the signal transductions of PAR and UVA and raise up flavonoid accumulation. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Synergistic effects of BAP and kinetin media additives on regeneration of vetiver grass (Vetiveria zizanioides L. Nash)(2016-05-01); Khunchuay, ChonnikarnRegeneration efficiency was enhanced by adding auxin and cytokinin at different concentrations to the media. It was found that the two highest frequencies-90 and 85%-of callus induction occured when the buds were cultured in an MS medium supplemented with 2 mgL<sup>-1</sup> a-naphthalene acetic acid (NAA) plus 1 mgL<sup>-1</sup> N<sup>6</sup>-benzylaminopurine (BAP) (CIM2) and in the same medium supplemented with 2 mgL<sup>-1</sup> NAA plus 1 mgL<sup>-1</sup> kinetin (CIM5), respectively. When cultured further in a plant regeneration medium supplemented with 1 mgL<sup>-1</sup> NAA and 2 mgL<sup>-1</sup> BAP (PRM1), these calli regenerated with high efficiencies, 80% for calli grown in CIM2 and 85% for calli grown in CIM5. The low BAP concentration in CIM1 (2 mgL<sup>-1</sup> NAA and 0.5 mgL<sup>-1</sup> BAP) resulted in a low regeneration efficiency and fewer shoots per callus even though the PRM3 regeneration medium had a high concentration of cytokinins (2 mgL<sup>-1</sup> BAP and 2 mgL<sup>-1</sup> kinetin) . However, the calli cultured in CIM2 without kinetin but with a suitable level of BAP still regenerated with high efficiencies in PRM2 and PRM3 that contained 1 and 2 mgL<sup>-1</sup> kinetin, respectively. Similarly, when calli cultured in CIM5 without BAP but with kinetin were regenerated in PRM1 with BAP alone, they also regenerated with a high regeneration efficiency. These results showed that culturing a specific tissue in a medium with suitable concentrations of NAA and BAP or kinetin resulted in a large number of multiple shoots, and BAP and kinetin worked synergistically to produce a high plant regeneration efficiency. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Tobacco expressing PAP1 increases the responses to PAR and UV-A by enhancing soluble sugars and flavonoids and elevating plant protections(2015-04-01); Kanthang, SuphaFive lines of transgenic tobacco over-expressing Production of Anthocyanin Pigment 1 (PAP1) cDNA were analysis of metabolic response against the radiation and their protection of the plant under tissue culture condition. PAP1 transgenic and wild type (WT) plants were treated with the radiations of photosynthetically activate radiation (PAR) or PAR combined with UV-A. All lines of transgenic significantly increased in amounts of p-coumaric acid, naringenin apigenin more than WT under both treatments. Additional UV-A radiating to plant rose up kaempferol content in WT plant (1.5 times) and in PAP1 transgenics (1.8 times). These transgenic plants treated under both conditions had also increased anthocyanin substances (pelargonidin) with significant value after compared to WT. Content of total soluble sugar (TSS) was related to the content of total flavonoids in transgenic. PAR combined with UV-A had a lower induction of the electrolyte leakage percentage and malondialdehyde (MDA) level in the transgenic leaf tissue compared to WT tissue. The metabolic substance levels were considered on its protection of plant cells. In transgenic tissue, the enhancement of apigenin level strongly diminished the increase level of electrolyte leakage while the levels of TSS, p-coumaric acid and naringinin less affected. Moreover, the increase levels of kaempferol and pelargonidin associated with the decrease level of MDA, while the TSS level reversely responded. The PAP1 transgenic increased response of light by adaptation of their metabolites (TSS, p-coumaric acid and flavonoids) consequently enhance parameter indicating protections of the cell.
