WebJul 11, 2012 · Evolutionary and reproductive success of angiosperms, the most diverse group of land plants, relies on visual and olfactory cues for pollinator attraction. Previous work has focused on elucidating the developmental regulation of pathways leading to the formation of pollinator-attracting secondary metabolites such as scent compounds and … The annual fluctuations in daylength that occur over much of the surface of our planet provide a reliable environmental cue regarding the time of year. It is not surprising, therefore, that the pathways that detect and promote flowering in response to photoperiod are among the most ancient and … See more Vernalization is defined as the process by which exposure to the cold of winter renders plants competent to flower (Kim et al., 2009). The … See more As discussed above, the basic photoperiod pathway appears to be conserved in flowering plants, and as illustrated in Figure 1, in Arabidopsis the circuitry of how the … See more In Arabidopsis, two antagonistic autonomous pathways regulate prevernalization levels of FLC expression. FLC is positively regulated by the FRI pathway and negatively regulated by a group of genes … See more

WebMay 1, 2024 · A serine/threonine-protein kinase gene, PvSTK1, related to flower development was cloned. Overexpression of PvSTK1 gene in Arabidopsis causes delayed flowering and floret sterility.. PvSTK1 is involved in the regulation of the photoperiod, vernalization, and autonomous pathway gene networks.. PvSTK1 makes Arabidopsis … WebNov 1, 2003 · Molecular genetics has identified dozens of genes that regulate flower development in Arabidopsis. However, the complexity of flower development suggests that many other genes are yet to be uncovered. WebApr 13, 2024 · The KEGG pathway “mRNA surveillance,” a quality control mechanism that degrades abnormal mRNAs (Kanehisa et al., 2016), was higher in the Rafflesia seed (Figure 4). mRNAs accumulate in seeds during development and are called stored mRNAs/long-lived mRNAs retaining their function as long as the seed is viable and serve as templates … grapes of wrath movie on tv
