Body color; Development; Genetic analysis; Hybrid; Transparent crucian carp

The aim of this study was to investigate the genetic mechanism of the transparent trait in transparent crucian carp. We observed body color development in transparent crucian carp larvae and analyzed heredity of color in hybrids produced with red crucian carp, ornamental carp, and red purse carp. The results showed that the body color of the newly hatched larvae matured into the adult ... more

Allele dosage; Endosperm constitution; Maize; Semiquantitative polymerase chain reaction

The lack of informativity of samples from heterozygotic individuals is one of the hindrances in the mapping of quantitative trait loci of outbred populations, since it is not normally possible to identify the origin of each allele. One way to include these individuals in analyses would be to genotype their endosperm, considering that a heterozygote (Aa) has AAa or Aaa ... more

Expression; FKBPs; Gene duplication; Maize

The receptors for the immunosuppression drugs FK506 and rapamycin are called FKBPs (FK506-binding proteins). FKBPs comprise a large family; they are found in many species, including bacteria, fungi, animals, and plants. As a class of peptidyl-prolyl cis-trans isomerase enzymes, the FKBP genes have been the focus of recent studies on plant stress tolerance and immunology. We ... more

Genetic linkage map; Maize; Segregation distortion; Shrinkage; Teosinte

Two genetic linkage maps of cultivated maize inbred lines and teosinte species were constructed. One population comprised 81 F2 individuals derived from a cross between maize inbred line B73 and Zea mays ssp parviglumis, while the second consisted of 63 backcross individuals from a cross of maize inbred line B73 with Z. mays ssp diploperennis ... more

Amplified fragment length polymorphism; Function annotation; Low phosphorus; Maize; tolerance

Soil contains a large amount of phosphorus, but plants cannot absorb most of this phosphorus effectively. Low inorganic phosphorus has been singled out as a major constraint that leads to a perpetually low Zea mays (maize) grain yield. The fundamental approach to solving this problem is to screen new genes of low phosphorous (LP) tolerance. Consequently, the exploration and ... more

Endosperm-specific promoter; Functional analysis; Maize; Promoter cloning

The ZmDULL1 gene encodes a starch synthase and is a determinant of the structure of endosperm starch in maize (Zea mays L.). However, little is known regarding the regulatory mechanism of the ZmDULL1 gene. In this study, we isolated and characterized the ZmDULL1 promoter (PDULL1), which is the 5' flanking region of ZmDULL1 in maize. Sequence ... more

endosperm; Gene expression; Hormone; Maize; Sugar

Starch is the major storage product in the endosperm of cereals. Its synthesis is closely related to sucrose metabolism. In our previous study, we found that the expression of most of the genes involved in starch synthesis might be regulated by sugars and hormones in the maize endosperm. However, little is known regarding the transcriptional regulation of genes involved in sucrose ... more

Ear row number; Grain yield; Maize; QTL

Ear row number (ERN) is not only a key trait involved in maize (Zea mays L.) evolution but is also an important component that is directly related to grain yield. In this study, quantitative trait loci (QTLs) for ERN were detected across two F2 populations that were derived from a same cross between B73 with 16 rows (N = 233) and SICAU1212 with four rows (N = 231). As a ... more

General combining ability; Genetic study; Maize; specific combining ability; Water-deficit maize

A set of sixty inbred lines of maize (Zea mays L.) were screened in the greenhouse at the seedling stage under both normal and water-deficit conditions. Six water deficit-tolerant inbred lines were selected based on root to shoot ratios. These selected lines were crossed in a diallel pattern. The parental, F1, and reciprocal cross plants were planted in a field under ... more

F2:3; Flowering-related traits; Maize; MQTL; QTL; RIL

Flowering-related traits in maize are affected by complex factors and are important for the improvement of cropping systems in the maize zone. Quantitative trait loci (QTLs) detected using different materials and methods usually vary. In the present study, 266 maize (Zea mays) F2:3 families and 301 recombinant inbred lines (RIL) derived from a cross between 08-641 ( ... more
