Background:

• Anthocyanins are vital plant pigments involved in various biological processes.
• Understanding the genetic regulation of anthocyanin biosynthesis is crucial for crop improvement.

Purpose of the Study:

• To identify candidate genes regulating anthocyanin biosynthesis in rice.
• To classify transcription factors associated with anthocyanin production.
• To discover novel genes involved in anthocyanin metabolism.

Main Methods:

• Microarray analysis was employed to screen candidate genes.
• A maximum boundary range algorithm was developed and utilized.
• Quantitative RT-PCR (RT-PCR) was used for gene expression validation.

Main Results:

• 2,617 candidate genes related to anthocyanin biosynthesis were identified.
• 235 transcription factor genes associated with anthocyanin were classified into nine groups.
• Nine novel, hypothetical genes were identified and validated for their expression across developmental stages.

Conclusions:

• The study identified key regulatory genes in rice anthocyanin biosynthesis.
• The newly developed algorithm demonstrates potential for gene discovery.
• Further validation of identified genes is recommended to elucidate their precise roles.
