Genetic Dissection of the Major Quantitative Trait Locus (qSE11), and Its Validation As the Major Influence on the Rate of Stigma Exsertion in Rice (Oryza sativa L.) [PDF]
Frontiers in Plant Science, 2017 The rate of stigma exsertion (SE) is an important trait in rice breeding because the efficiency of hybrid rice seed production can be improved by increasing the percentage of stigmas that exsert.

Crop Journal, 2019 Stigma exsertion in male sterile lines of hybrid rice is important for seed yield. In the present study, ZS616 [Oryza sativa subsp. Xian (indica)], a male sterile line with a stigma exsertion rate (SER) as high as 94.5%, was crossed to DS552, a japonica ...

ATP-Binding Cassette G Transporters SGE1 and MtABCG13 Control Stigma Exsertion [PDF]
Plant Physiology, 2020 Stigma exsertion is an important agricultural trait that facilitates the application of heterosis in crop breeding. Although several quantitative trait loci associated with stigma exsertion have been fine-mapped or cloned, the underlying genetic basis, particularly in legumes, remains unclear. In this study, we identified and characterized the exserted

Fine-Mapping and Candidate Gene Analysis of qSERg-1b from O. glumaepatula to Improve Stigma Exsertion Rate in Rice [PDF]
AgronomyThe stigma exsertion rate (SER) is one of the important factors affecting the seed production of hybrid rice. In the genus Oryza, wild rice species usually show higher SERs than cultivars.

Latitudinal trends in mating system traits in the highly self-fertilizing Lobelia inflata revealed by community science. [PDF]
Ecol Evol, 2023 Lobelia inflata is completely selfing in several populations in the north of its range, which we hypothesize is the result of selection for reproductive assurance under mate limitation at range margins. By scoring community science images for a morphological trait that indicates outcrossing capacity (exsertion of the floral style), we find that ...

Genetics of sterility behaviour in Thermo Sensitive Genic Male Sterility system in rice (Oryza sativa L. ) [PDF]
Electronic Journal of Plant Breeding, 2023 A total of 1493 F2 populations of five crosses were evaluated to study the TGMS nature under high temperature regime at Coimbatore. The present study revealed that the observed variation among 1493 F2 populations showed 25 per cent of population ...

Targeted manipulation of grain shape genes effectively improves outcrossing rate and hybrid seed production in rice. [PDF]
Plant Biotechnol J, 2023 Summary Stigma exsertion rate (SER) of the male sterile line is a key limiting factor for hybrid seed production in rice. Although a large number of quantitative trait loci associated with SER have been reported, few genes have been molecularly cloned and functionally characterized, severely hindering the genetic improvement of SER of the male sterile ...

Tomato stigma exsertion induced by high temperature is associated with the jasmonate signalling pathway [PDF]
Plant, Cell & Environment, 2018 AbstractHigh temperature (HT) is becoming an increasingly serious factor in limiting crop production with global climate change. During hot seasons, owing to prevailing HT, cultivated tomatoes are prone to exhibiting stigma exsertion, which hampers pollination and causes fruit set failure. However, the underlying regulatory mechanisms of the HT‐induced
