AbstractThe indica rice Xieqingzao eB1 (XQZ eB1), a mutant with an elongated uppermost internode, was produced by mutagenesis from elite maintainer line Xieqingzao B (XQZ B) using γ-radiation. Compared with the wild-type XQZ B, plant height and the length of the rice panicle neck, second internode and third internode from the panicle were elongated significantly in XQZ eB1. Genetic analysis indicated that the trait for uppermost internode elongation of XQZ eB1 is controlled by a single recessive gene eui1, which is allelic to that of IR50eui (derived from 76:4512). Further studies were carried out using the bulk segregated analysis approach. An F3 population, derived from the cross XQZ eB1×Aijiaonante, was used to map the mutant gene eui1. Two SSR makers, RM164 and AC9, were identified to link to eui1, their genetic distances to eui1 being 18.4 and 7.9 cM, respectively. The eui1 gene was also mapped to the long arm of chromosome 5 in this research.

AbstractThe piezochromic fluorescence (FL) of a distyrylpyrazine derivative, 2,3-diisocyano-5,6-distyrylpyrazine (DSP), was investigated in this study. Depending on the recrystallization method, DSP afforded two different crystals with green and orange FL emission. The orange color FL emission crystal (O-form) was easily converted to the green color FL emission one (G-form) by manual grinding. The G-form was also converted to a slightly different orange color FL emission crystal (RO-form) by a weak UV irradiation. When the RO-form was ground again, the G-form was regenerated. The FL colors changed between the G- and RO-forms over several ten times by repeated mechanical grinding and UV irradiation. The FL, UV–visible, 1H-NMR and XRD results showed that the O (or RO)-to-G transformation induced by mechanical stress results from the change of degree of molecular stacking from dense molecular stacking structure to relatively loose molecular stacking structure, whereas the G-to-RO reconversion by UV irradiation results from return to dense molecular stacking structure again due to lattice movement (lattice slipping) allowed by photocycloaddition in solid-state.

Internode length and stem diameter are the primary traits affecting the lodging resistance of rice. Traits related to the length of the panicle (LP), uppermost internode (LUI), second internode (LSI), third internode (LTI), fourth internode (LFI), lowest internode (LLI) as well as stem diameter at the uppermost internode (SDUI), second internode (SDSI), third internode (SDTI), fourth internode (SDFI), and lowest internode (SDLI) in 120 Cheongcheong/Nagdong doubled haploid population were investigated using a quantitative trait locus (QTL) analysis. Thirty-four QTL regions affected LP and the length of each internode. Twenty-six QTL regions were associated with the stem diameter of each internode. RM12285-RM212 on chromosome 1 contained 10 QTLs related to the internode length, which have overlapped for over 2 years. Twenty-three candidate genes were screened using mark interval. Among the candidate genes, Os01g0803900, named OsCYPq1, which is in the Cytochrome P450 family, might be involved in gibberellins (GA) synthesis. GA is an essential plant growth regulator that affects plant height. OsCYPq1 catalyzes oxidation steps in the middle part of the GA pathway. OsCYPq1 is expected to provide valuable information to improve the marker assessment for target traits and QTL gene cloning in rice.

In the present study, a mutated chimericorf364, namedorf366-c, was identified in a maize C type cytoplasmic male sterile line (CMS-C) by PCR and RT-PCR. Four base pair adjacent base substitution mutations (CAAA to TTTT) and eight bp insertion mutations were found inorf366-ccompared withorf364. ORF366-C was predicted to contain one membrane-spanning domain using TMHMM online software. Real-time quantitative PCR analysis showed thatorf366-cwas upregulated in the CMS-C line in comparison to its maintainer line at the uninucleate stage. The protokaryotic protein expression oforf366-cinEscherichia colishowed that ORF366-C could be a cytotoxic protein. All the results indicated thatorf366-cmay be associated with maize CMS-C.
