Annotation PubMed Id
In mutants the number of starch granules per plastid dramatically decreased leading to a large increase in their size. 17217470
The data point to a complex mechanism for starch granule formation and to the different abilities of SSIV and SSIII to support this process in Arabidopsis leaves. 19666739
Overexpression of SSIV induces the accumulation of starch in Arabidopsis. 21645200
SS4 is an essential component of a mechanism that coordinates granule formation with chloroplast division during leaf expansion. 23952675
