Other claims from this paper (11)
- Observation Under high temperature the sterile anther of PK3-12 was small, with a little abortive pollen in the anther room.
- Observation 31 differentially expressed proteins with more than two-fold expression change were identified between sterile and fertile anthers.
- Observation Six protein spots showed increased expression.
- Observation Eleven protein spots showed reduced expression.
- Observation Twelve protein spots showed complete inhibition.
- Observation Two protein spots showed induced expression.
- Observation Fifteen differentially expressed proteins were identified by mass spectrometry as involved in cellular processes including signal transduction, glyoxylate and dicarboxylate metabolism, glycolysis gluconeogenesis, secondary metabolite biosynthesis, amino acid biosynthesis, chorismate biosynthesis and carbon metabolism.
- Observation The BrrbcL gene, encoding a Rubisco subunit-binding accessory protein, had an open reading frame of 1095 bp.
- Observation The BrrbcL ORF encoded 364 amino acids.
- Association Expression of BrrbcL, annexin (ANN) and BetVI genes was significantly down-regulated during sterile anther development compared with fertile anthers.
- Mechanism The authors suggest that these down-regulated genes may participate in fertility transformation of the thermo-sensitive sterile line PK3-12S.
