ABSTRACT = {The chloroplast NAD(P)H dehydrogenase (NDH) complex, as one of
the most important photosynthesis protein complexes in thylakoid membrane, is
involved in photosystem I (PSI) cyclic electron transport (CEF). Under abiotic
environmental stress, the photosynthetic apparatus is susceptible to the damage
caused by the strong light illumination. However, the enhancement of NDHdependent CEF could facilitate the alleviation of the damage to the photosynthetic
apparatus. The NdhB subunit encoded by chloroplast genome is one of most
important subunits of NDH complex and consists of 510 amino acids. Here,
according to cloning <i>ndh</i>B from Melrose (cultivated soybean), ACC547 (wild
salt-tolerant soybean), S113-6 and S111-9 (hybrid descendant), based on the comparison and analysis of the sequences of NdhB subunits, we found that there is a
novel thylakoid transit peptide of NdhB subunit in S111-9. In addition, crosslink
immunoprecipitation, immunogold labeling and co-expression of GFP fusion protein indicated that the novel thylakoid transit peptide is favorable to the expression
and localization of NdhB subunit in chloroplast. Therefore, we suggest that this
novel thylakoid transit peptide plays the same role as chaperonin and contributes
to facilitating the expression and localization of NdhB subunit.},
