Please input one-sentence summary here. The current work confirms that these six genes comprise the entire rice Sus gene family.Sus is involved in numerous and diverse growth processes in the rice plant. This article mainly discuss SUS3, about its function, structure, expression, evolution, and knowledge Extension.
SUS4 plays an important role in the grain filling process.It was predominantly expressed in the caryopsis, with potential roles in carbon allocation within the filling grain.
Please input expression information here. The total abundance of the mRNAs for SUS4 genes as normalized to the constitutive polyubiquitin ( RUBIQ1) gene transcript level. The mRNA levels for SUS4 genes were highest in elongating sink organs such as roots,developing leaf blades and elongating uppermost internodes.The transcripts of SUS4 were most abundant in either the panicles at the grain filling stage of development or dry seeds respectively, and were absent from or expressed only at very low levels in the other tissues examined. Sus activity is suggested to be one of the key factors for the altered sugar metabolism in rice plants under submerged condition. The overall level of Sus activity remained relatively stable irrespective of germination conditions, but was higher in shoots of seedlings germinated under submerged condition compared to those germinated in the air at all the time points examined
