Genetic Analysis and Fine Mapping of QTLs for Stigma Exsertion Rate in Rice [PDF]

Rice
Stigma exsertion rate (SER) is a crucial trait that influences the seed production of hybrid rice by determining the outcrossing ability of male sterile lines (MSLs).

Identification and expression profiling of microRNAs involved in the stigma exsertion under high-temperature stress in tomato [PDF]

BMC Genomics, 2017
Background Autogamy in cultivated tomato varieties is a derived trait from wild type tomato plants, which are mostly allogamous. However, environmental stresses can cause morphological defects in tomato flowers and hinder autogamy.

Dissection of closely linked QTLs controlling stigma exsertion rate in rice by substitution mapping. [PDF]

Theor Appl Genet, 2021
Abstract Key message Through substitution mapping strategy, two pairs of closely linked QTLs controlling stigma exsertion rate were dissected from chromosomes 2 and 3 and the four QTLs were fine mapped. Abstract Stigma exsertion rate (SER) is an important trait affecting the

Four QTLs control stigma exsertion rate by changing stigma size in rice. [PDF]

Mol Breed
The stigma exsertion rate (SER) is a key trait for the outcrossing ability of hybrid rice, which directly affects the yield of hybrid seeds in hybrid seed production. In previous studies, we have located 18 QTLs for SER using single-segment substitution lines in rice. In this study, we found that 4 of 18 QTLs for SER controlled stigma size (SS).

Mutation in HER1 enhances stigma exsertion and hybrid seed production in rice [PDF]

Nature Communications
Hybrid rice has achieved a significant leap in rice yield, but the low outcrossing rate of sterile lines limits hybrid seed production due to rice’s self-pollinating habits, constraining the further development and widespread adoption of hybrid rice ...

qSE7 is a major quantitative trait locus (QTL) influencing stigma exsertion rate in rice (Oryza sativa L.). [PDF]

Sci Rep, 2018
AbstractStigma exsertion is a key determinant to increase the efficiency of commercial hybrid rice seed production. The major quantitative trait locus (QTL) qSE7 for stigma exsertion rate was previously detected on the chromosome 7 using 75 Chromosome Segment Substitution Lines (CSSLs) derived from a cross between the high stigma exsertion indica ...

Effects of gibberellin on tomato stigma exsertion and hormone-related gene expression under moderate heat stress

浙江大学学报. 农业与生命科学版, 2015
Tomato, one of the most important vegetable crops, is widely cultivated around the world. Blossom drop is a common growing problem that can be extremely frustrating to the tomato production. The most frequent cause of tomato blossom drop is inappropriate

Detection of dominant QTLs for stigma exsertion ratio in rice derived from Oryza rufipogon accession 'W0120'. [PDF]

Breed Sci, 2019
Stigma exsertion can enhance the outcrossing fertility in rice. Dominant genes for this trait are expected to be essential for the effective application of a novel outcrossing-based breeding system that uses male sterility in rice, which is normally autogamous.

Genetic mapping of quantitative trait loci for the stigma exsertion rate in rice (Oryza sativa L.)

Journal of Integrative Agriculture, 2017
The efficiency of hybrid rice seed production can be improved by increasing the percentage of exserted stigmas. To identify quantitative trait loci (QTLs) for this trait, we conducted QTL mapping using 75 chromosome segment substitution lines (CSSLs ...

Genome-wide Association Analyses Reveal the Genetic Basis of Stigma Exsertion in Rice [PDF]

Molecular Plant, 2017
Stigma exsertion, a key determinant of the rice mating system, greatly contributes to the application of heterosis in rice. Although a few quantitative trait loci associated with stigma exsertion have been fine mapped or cloned, the underlying genetic architecture remains unclear.
