Flowering Time Genes Heading date 1 and Early heading date 1 Together Control Panicle Development in Rice
Although flowering time is often associated with plant size, little is known about how flowering time genes affect plant architecture. We grew four rice lines having different flowering time genotypes (hd1 ehd1, hd1 Ehd1, Hd1 ehd1 and Hd1 Ehd1) under distinct photoperiod conditions. By using genotype-treatment combinations that resulted in similar flowering times, we were able to compare the ef...
متن کاملHeading Date Is Not Flowering Time in Spring Barley
Understanding the stages of floral development is one of the major goals of crop breeding to produce new varieties that are better adapted to environmental cues with improved yield. The phase transition is a quantitative trait that is predominantly genetically controlled with a complex genetic network integrating endogenous and environmental factors. In recent years, it has become evident that ...
متن کاملThe RING-Finger Ubiquitin Ligase HAF1 Mediates Heading date 1 Degradation during Photoperiodic Flowering in Rice.
The photoperiodic response is one of the most important factors determining heading date in rice (Oryza sativa). Although rhythmic expression patterns of flowering time genes have been reported to fine-tune the photoperiodic response, posttranslational regulation of key flowering regulators has seldom been elucidated in rice. Heading date 1 (Hd1) encodes a zinc finger transcription factor that ...
متن کاملImportance of QTL Mapping for Heading Date in Rice
Heading date in rice is one of the most important indices in rice breeding being governed by multiple genes known as quantitative trait loci (QTLs). This character along with grain yield determines the commercial potential of any rice cultivar. In the last three decades the development of DNA markers have led to the precise analysis of QTLs. Various mapping populations are being used to explore...
