Trafficking Defects

AbstractDense vesicles (DVs) are Golgi-derived plant-specific carriers that mediate post-Golgi transport of seed storage proteins in angiosperms. How this process is regulated remains elusive. Here, we report a rice (Oryza sativa) mutant, named glutelin precursor accumulation8 (gpa8) that abnormally accumulates 57-kDa proglutelins in the mature endosperm. Cytological analyses of the gpa8 mutant revealed that proglutelin-containing DVs were mistargeted to the apoplast forming electron-dense aggregates and paramural bodies in developing endosperm cells. Differing from previously reported gpa mutants with post-Golgi trafficking defects, the gpa8 mutant showed bent Golgi bodies, defective trans-Golgi network (TGN), and enlarged DVs, suggesting a specific role of GPA8 in DV biogenesis. We demonstrated that GPA8 encodes a subunit E isoform 1 of vacuolar H+-ATPase (OsVHA-E1) that mainly localizes to TGN and the tonoplast. Further analysis revealed that the luminal pH of the TGN and vacuole is dramatically increased in the gpa8 mutant. Moreover, the colocalization of GPA1 and GPA3 with TGN marker protein in gpa8 protoplasts was obviously decreased. Our data indicated that OsVHA-E1 is involved in endomembrane luminal pH homeostasis, as well as maintenance of Golgi morphology and TGN required for DV biogenesis and subsequent protein trafficking in rice endosperm cells.

Transcript Variants

High-temperature stress during the grain filling stage has a deleterious effect on grain yield and end-use quality. Plants undergo various transcriptional events of protein complexity as defensive responses to various stressors. The “Keumgang” wheat cultivar was subjected to high-temperature stress for 6 and 10 days beginning 9 days after anthesis, then two-dimensional gel electrophoresis (2DE) and peptide analyses were performed. Spots showing decreased contents in stressed plants were shown to have strong similarities with a high-molecular glutenin gene, TraesCS1D02G317301 (TaHMW1D). QRT-PCR results confirmed that TaHMW1D was expressed in its full form and in the form of four different transcript variants. These events always occurred between repetitive regions at specific deletion sites (5′-CAA (Glutamine) GG/TG (Glycine) or (Valine)-3′, 5′-GGG (Glycine) CAA (Glutamine) -3′) in an exonic region. Heat stress led to a significant increase in the expression of the transcript variants. This was most evident in the distal parts of the spike. Considering the importance of high-molecular weight glutenin subunits of seed storage proteins, stressed plants might choose shorter polypeptides while retaining glutenin function, thus maintaining the expression of glutenin motifs and conserved sites.
