Frequently asked questions

Q1. What are the future works in "New insights into the regulation of anthocyanin biosynthesis in fruits" ?

These studies will 11 deepen their understanding of the role of interaction between these key players in the 12 regulation of the pathway, which is likely to become one of the most interesting targets for 13 future breeding work. The ongoing release of transcriptome and genome information will 14 enable studies involving a wider range of fruit bearing species, which further widens their 15 understanding on this topic. 

Q2. What is the simplest way to regulate anthocyanin biosynthesis?

Light related control of 22 anthocyanin biosynthesis occurs via light receptors that interact with ubiquitin E3 ligase 2326COP1 that ubiquitinates degradation multiple light-response effectors including HY5, or 1 interact directly with certain anthocyanin biosynthesis related MYB transcription factors to 2 induce transcription of structural pathway genes. 

Q3. What are the key factors in anthocyanin biosynthesis?

Plant 19 hormones (auxin, ABA, ethylene, JA, GA) and certain MADS box transcription factors are key 20 factors in development related regulation of anthocyanin biosynthesis. 

Q4. what is the ectopic expression of apple F3’H genes?

Ectopic expression of apple F3’H genes contributes to anthocyanin 9accumulation in the Arabidopsis tt7 mutant grown under nitrogen stress. 

Q5. What is the role of abscisic acid in the development of Vitis vinif?

Gene expression and metabolite profiling of developing highbush 1 blueberry fruit indicates transcriptional regulation of flavonoid metabolism and activation of 2 abscisic acid metabolism. 

Q6. What are the characteristics of anthocyanins in ripe fruit?

The composition of anthocyanins in ripe fruit 2314is formed via the function of complicated metabolic networks regulated by genetic, 1 developmental and environmental factors. 

Q7. How is the transcription of anthocyanins regulated?

The transcription of structural anthocyanin biosynthesis genes is 17 regulated by MYB/bHLH/WD40 complex, in which different MYBs can activate specific parts 18 of the pathway and respond differentially on developmental and environmental cues. 

Q8. What is the COP1 mediated Ub-proteasome system?

COP1 mediated Ub-proteasome system has recently been shown to have a role inlight depended regulation of anthocyanin biosynthesis in apple skin. 

Q9. what is the role of methyl jasmonate in fruit ripening?

Planta 204, 444-11 449 1251 Rudell, D.R. et al. (2005) Preharvest application of methyl jasmonate to ‘Fuji’ apples 13 enhances red coloration and affects fruit size, splitting and bitter pit incidence. 

Q10. what is the myb transcription factor in grapevine?

Heredity 104, 351-362 1123 Akagi, T. et al. (2009) DkMyb4 is a Myb transcription factor involved in proanthocyanidin 12 biosynthesis in persimmon fruit. 

Q11. How does the temperature affect anthocyanin biosynthesis?

Cold temperature can affect together with 3 light response via the same signaling pathway, but it is not understood by which mechanism 4 other observed temperature or environmental effects, such as nitrogen level, regulate the 5 anthocyanin biosynthesis.
