| Abstract |
Rice prolamins are accumulated in endoplasmic reticulum (ER)-derived proteins bodies, although conserved sequences retained in ER are not confirmed. We investigated portion sequences of prolamins that must accumulate in PB-Is. Rice seed prolamins are accumulated in endoplasmic reticulum (ER)-derived protein body type I (PB-I), but ER retention sequences in rice prolamin polypeptides have not been confirmed. Here we investigated the lengths of the prolamin portion sequences required for accumulation in PB-Is. Of the rice prolamins, we compared 13a and 13b prolamins because the amino acid sequences of these prolamins are quite similar except for the presence or absence of Cys-residues. We also generated and analyzed transgenic rice expressing several prolamin portion sequence-GFP fusion proteins. We observed that in 13a prolamin, when the portion sequences were extended more than the 68th amino acid residue from the initiating methionine, the prolamin portion sequence-GFP fusion proteins were accumulated in PB-Is. In 13b prolamin, when the portion sequences were extended by more than the 82nd amino acid residue from the initiating methionine, the prolamin portion sequence-GFP fusion proteins were accumulated in PB-Is. When those fusion proteins were extracted under non-reduced or reduced conditions, the 13a prolamin portion sequence-GFP fusion proteins in PB-Is were soluble under only the reduced condition. In contrast, 13b prolamin portion sequence-GFP fusion proteins were soluble under both non-reduced and reduced conditions. These results suggest that the accumulation of 13a prolamin in PB-Is is associated with the formation of disulfide bonds and/or hydrophobicity in 13a prolamin polypeptide, whereas the accumulation of 13b prolamin in PB-Is was less involved in the formation of disulfide bonds. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 05 October 2019.
All research outputs
#17,881,664
of 22,958,253 outputs
Outputs from Plant Cell Reports
#1,841
of 2,192 outputs
Outputs of similar age
#294,183
of 421,341 outputs
Outputs of similar age from Plant Cell Reports
#29
of 35 outputs
Altmetric has tracked 22,958,253 research outputs across all sources so far. This one is in the 19th percentile – i.e., 19% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,192 research outputs from this source. They receive a mean Attention Score of 4.1. This one is in the 13th percentile – i.e., 13% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 421,341 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 26th percentile – i.e., 26% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 35 others from the same source and published within six weeks on either side of this one. This one is in the 2nd percentile – i.e., 2% of its contemporaries scored the same or lower than it.
