Abstract：This paper studied the characteristics of albino seed pod in cabbage alb1 by paraffin section
technique．The results showed that the cells were abnormal in morphology development，cell walls were
deformed and cell boundaries were not obvious．The results of genetic analysis showed that the separation
ratio of green pod to albino pod was 3∶1，indicating that this albino seed pod trait is controlled by a single
recessive gene．The differential expression in albino pod mutant alb1 and green pod Chinese kale TO1000 were
analyzed by high-throughput RNA-sequencing．A total of 4 530 genes were differentially expressed between
alb1 and TO1000．Among them，2 569 were up-regulated genes and 1 961 were down-regulated genes．
These differentially expressed genes were mainly involved in ribosome，plant hormone signal transduction
and fatty acid elongation．Plant hormone signal transduction was especially important for construction of cell
morphology，which might be the important reason for cell development malformation and emergence of albino
seed pod．
