Identification of Quantitative Trait Loci for Rice Quality in a Population of Chromosome segment substitution Lines

The demand for high quality rice represents a major issue in rice production. The primary components of rice grain quality include appearance, eating, cooking, physico-chemical, milling and nutritional qualities. Most of these traits are complex and controlled by quantitative trait loci （QTLs）, so the genetic characterization of these traits is more difficult than that of traits controlled by a single gene. The detection and genetic identification of QTLs can provide insights into the genetic mechanisms underlying quality traits. Chromosome segment substitution lines （CssLs） are effectivetools used in mapping QTLs. In this study, we constructed 154 CssLs from backcross progeny （BC3F2） derived from a cross between ＇Koshihikari＇（an Oryza sativa L. ssp. japonica variety） as the recurrent parent and ＇Nona Bokra＇（an O. sativa L. ssp. indica variety） as the donor parent. In this process, we carried out marker-assisted selection by using 102 cleaved amplified polymorphic sequence and simple sequence repeat markers covering most of the rice genome. Finally, this set of CssLs was used to identify QTLs for rice quality traits. Ten QTLs for rice appearance quality traits were detected and eight QTLs concerned physico-chemical traits. These results supply the foundation for further genetic studies and breeding for the improvement of grain quality.

plant seed oil is important for human dietary consumption and industrial application. The oil trait is controlled by quantitative trait loci （QTLs）, but no QTLs for fatty acid composition are known in rice, the monocot model plant. QTL analysis was performed using F2 and F2：3 progeny from a cross of an indica variety and a japonica variety. Gas chroma- tography-mass spectrometry （GC-Ms） analysis revealed significant differences between parental lines in fatty acid com- position of brown rice oil, and 29 associated QTLs in F2 and/or F2：3 populations were identified throughout the rice genome, except chromosomes 9 and 10. Eight QTLs were repeatedly identified in both populations across different envi- ronments. Five loci pleiotropically controlled different traits, contributing to complex interactions of oil with fatty acids and between fatty acids. Nine rice orthologs of Arabidopsis genes encoding key enzymes in lipid metabolism co-localized with 11 mapped QTLs. A strong QTL for oleic （18：1） and linoleic （18：2） acid were associated with a rice ortholog of a gene encoding acyI-CoA：diacylglycerol acyltransferase （DGAT）, and another for palmitic acid （16：0） mapped similarly to the acyl- ACP thioesterase （FatB） gene ortholog. Our approach rapidly and efficiently identified candidate genes for mapped QTLs controlling fatty acid composition and oil concentration, providing information for improving rice grain quality by marker assisted selection.

Grain size and shape are important determinants of grain weight and yield in rice. Here, we report a new major quantitative trait locus （QTL）, qTGW3, that controls grain size and weight in rice. This locus, qTGW3, encodes OssK41 （also known as OsGsK5）, a member of the GLYCOGEN sYNTHAsE KINAsE 3/sHAGGY-like family. Rice near-isogenic lines carrying the loss-of-function allele of OssK41 have increased grain length and weight. We demonstrate that OssK41 interacts with and phosphorylates AUXIN REsPONsE FACTOR 4 （OsARF4）. Co-expression of OssK41 with OsARF4 increases the accumulation of OsARF4 in rice protoplasts. Loss of function of OsARF4 results in larger rice grains. RNA-sequencing analysis suggests that OsARF4 and OssK41 repress the expression of a common set of downstream genes, including some auxin-responsive genes, during rice grain development. The loss-of-function form of OssK41 at qTGW3 represents a rare allele that has not been extensively utilized in rice breeding. suppression of OssK41 function by either targeted gene editing or QTL pyramiding enhances rice grain size and weight. Thus, our study reveals the important role of OssK41 in rice grain development and provides new candidate genes for genetic improvement of grain yield in rice and perhaps in other cereal crops.

Putative zeatin O-glucosyltransferase OscZOG1 regulates root and shoot development and formation of agronomic traits in rice

引用

Journal of Integrative plant Biology 2016年第7期58卷 627-641页

As a ubiquitous reaction, glucosylation controls the bioactivity of cytokinins in plant growth and development. Here we show that genetic manipulation of zeatin-O- glucosylation regulates the formation of important agronomic traits in rice by manipulating the expression of OscZOG1 gene, encoding a putative zeatin O-glucosyltransferase. We found that OscZOG~ was preferentially expressed in shoot and root meristematic tissues and nascent organs. The growth of lateral roots was stimulated in the overexpression lines, but inhibited in RNA interference lines. In shoots, knockdown of OscZOG1 expression by RNA interference significantly im- proved tillering, panicle branching, grain number per panicle and seed size, which are important agronomic traits for grain yield. In contrast, constitutive expression of OscZOG1 leads to negative effects on the formation of the grain-yielding traits with a marked increase in the accumulation levels of cis-zeatin O-glucoside （cZOG） in the transgenic rice plants. In this study,our findings demonstrate the feasibility of improving the critical yield-determinant agronomic traits, including tiller number, panicle branches, total grain number per panicle and grain weight by downregulating the expression level of OscZOG1. Our results suggest that modulating the levels of cytokinin glucosylation can function as a fine-tuning switch in regulating the formation of agronomic traits in rice.

Nitric Oxide Regulates Dark-Induced Leaf senescence Through EIN2 in Arabidopsis

引用

Journal of Integrative plant Biology 2012年第8期54卷 516-525页

The nitric oxide （NO）-deficient mutant nosllnoal exhibited an early leaf senescence phenotype. ETHY- LENE INsENsITIVE 2 （EIN2） was previously reported to function as a positive regulator of ethylene- induced senescence. The aim of this study was to address the question of how NO interacts with ethylene to regulate leaf senescence by characterizing the double mutant ein2-1 nosllnoal （Arabidopsis thaliana）. Double mutant analysis revealed that the nosllnoal-mediated, dark-induced early senescence phenotype was suppressed by mutations in EIN2, suggesting that EIN2 is involved in nitric oxide signaling in the regulation of leaf senescence. The results showed that chlorophyll degradation in the double mutant leaves was significantly delayed. In addition, nosllnoal-mediated impairment in photochemical efficiency and integrity of thylakoid membranes was reverted by EIN2 mutations. The rapid upregulation of the known senescence marker genes in the nosl/noal mutant was severely inhibited in the double mutant during leaf senescence. Interestingly, the response of dark-grown nosl/noal mutant seedlings to ethylene was similar to that of wild type seedlings. Taken together, our findings suggest that EIN2 is involved in the regulation of early leaf senescence caused by NO deficiency, but NO deficiency caused by NOsIlNOA1 mutations does not affect ethylene signaling.

Dissecting the Genetic Basis of Extremely Large Grain shape in Rice Cultivar 'JZ1560'

Journal of genetics and Genomics 2012年第7期39卷 325-333页

Rice grain shape, grain length （GL）, width （GW）, thickness （GT） and length-to-width ratio （LWR）, are usually controlled by multiple quantitative trait locus （QTL）. To elucidate the genetic basis of extremely large grain shape, QTL analysis was performed using an F2 population derived from a cross between a japonica cuttivar ＇JZI560＇（extremely large grain） and a contrasting indica cultivar ＇FAZI＇（small grain）. A total number of 24 QTLs were detected on seven different chromosomes. QTLs for GL, GW, GT and LWR explained 11.6%, 95.62%, 91.5% and 89.9% of total phenotypic variation, respectively. Many QTLs pleiotropically controlled different grain traits, contributing complex traits correlation. GW2 and qsW5/GW5, which have been cloned previously to control GW, showed similar chromosomal locations with qGW2-1/qGT2-1/qLWR2-2 and qGW5-2/qLWR5-1 and should be the right candidate genes. plants pyramiding GW2 and qsW5/GW5 showed a significant increase in GW compared with those carrying one of the two major QTLs. Furthermore, no significant QTL interaction was observed between GW2 and qsW5/GW5. These results suggested that GW2 and qsW5/GW5 might work in independent pathways to regulate grain traits. ＇JZ1560＇ alleles underlying all QTLs contributed an increase in GW and GT and the accumulation of additive effects generates the extremely large grain shape in ＇JZ1560＇.
