Phosphoenolpyruvate carboxylase gene; Photosynthetic enzyme activity; Rice

The morphology and photosynthetic enzyme activity were studied in maize phosphoenolpyruvate carboxylase transgenic rice and non-transgenic rice. The results showed that compared with non-transgenic rice, phosphoenolpyruvate carboxylase transgenic rice was taller and had a stronger stalk, wider leaves, and more exuberant root system, with increased photosynthetic enzyme activity and improved ... more

Effect evaluation; Grain gene; Molecular markers; Rice; Verification

Grain size is an important trait that directly influences the yield of rice. Validation and evaluation of grain genes is important in rice genetic studies and for breeding. In a population of 240 recombinant inbred lines (RILs) derived from a cross between an extra-large grain japonica variety TD70 and a small grain indica variety Kasalath, we mapped 19 QTLs controlling grain ... more

Abiotic stress; AWPM-19-like; Membrane protein; Panicle; Rice

The plant-specific AWPM-19-domain proteins play important roles in plant development and stress responses. In the current study, OsPM19L1 encoding Oryza sativa AWPM-19-like protein 1 was isolated from rice. Tissue-specific gene expression analysis revealed that OsPM19L1 was highly expressed in the leaf sheath of rice. Interestingly, expression of OsPM19L1 ... more

Grain size; GS3; Haplotype; qGL3; Rice

Grain size is an important trait that directly influences rice yield. The qGL3 and GS3 genes are two putative regulators that play a role in grain size determination. A single rare nucleotide substitution (C→A) at position 1092 in exon 10 of qGL3 might be responsible for variations in grain size. However, little is known about the haplotype variations of qGL3 ... more

Classical genetic analysis; Cucumber (Cucumis sativus L.); Low-light tolerance; QTLs; Seedling

The low-light tolerance index was investigated in a set of 123 F2:3 lines during the seedling stage across 2 seasons, and the heredity of low-light tolerance was assessed via different ge­netic analysis methods. The results of the classical analysis showed that low-light tolerance is controlled by an additive-dominant poly­gene, and the polygenic inheritance rate of separate ... more

Fast kernel dehydration; Maize; Physiological maturity stage; QTLs; Silking stage

In order to understand the effect of grain moisture of inbred lines at the silking and physiological maturity stages on kernel dehydration rate, 59 maize inbred lines from six subgroups were selected. Grain moisture was measured and QTLs associated with kernel dehydration were mapped. A rapid dehydration evaluation and association analysis revealed eight inbred lines with faster ... more

Breeding direction; Indigenous breeds; Molecular marker; Polymorphic site

The direction of production for indigenous chicken breeds is currently unknown and this knowledge, combined with the development of chicken genome-wide association studies, led us to investigate differences in specific loci between broiler and layer chicken using bioinformatic methods. In addition, we analyzed the distribution of these seven identified loci in four Chinese indigenous ... more

Germplasm; Meristem culture; Molecular marker; Somaclonal variation

Molecular markers are efficient for assessing the genetic fidelity of various species of plants after in vitro culture. In this study, we evaluated the genetic fidelity and variability of micropropagated cassava plants (Manihot esculenta Crantz) using inter-simple sequence repeat markers. Twenty-two cassava accessions from the Embrapa Cassava & Fruits Germplasm Bank ... more

The present study investigated the genetic characterization of red-colored heartwood Chinese fir [Cunninghamia lanceolata (Lamb.) Hook.] in Guangxi using 21 simple sequence repeat (SSR) markers and analyzes of the genetic variation (N = 149) in samples obtained from five sites in Guangxi Province, China. The number of different alleles and the Shannon’s information index per ... more
