Rapeseed team reveals metabolite transporters BnaPPT1 and BnaBASS2 affecting canola grain oil...

Nanhu News Network News (Correspondent Tang Shan) Recently, the rapeseed team of our school published a report entitled "BnaPPT1 is essential for chloroplast development and seed oil accumulation in Brassica napus" and " Pyruvate transporter BnaBASS2 impacts seed oil accumulation in Brassica napus" research paper

Within plant cells, the phosphoenol pyruvate/phosphate transporter (PPT) and bile acid-sodium transporter (BASS2) transport the glycolytic pathway metabolites phosphoenol pyruvate and pyruvate from the cytoplasm to the plastium, thereby satisfying fatty acid synthesis and other metabolic activities

The study, published in the Plant Biotechnology Journal, created an overexpressed canola material for BnaA05.

【English Abstract】

Introduction

Phosphoenolpyruvate/phosphate translocator (PPT) transports phosphoenolpyruvate from the cytosol into the plastid for fatty acid (FA) and other metabolites biosynthesis.

Objectives

This study investigated PPTs’ functions in plant growth and seed oil biosynthesis in oilseed crop Brassica napus.

Methods

We created over-expression and mutant material of BnaPPT1.

Results

The plastid membrane localized BnaPPT1 was found to be required for normal growth of B.

Conclusion

Our results suggest that BnaPPT1 is necessary for plant chloroplast development, and it plays an important role in maintaining plant growth and promoting seed oil accumulation in B.
