Mutations of SSIIa have been observed in wheat and rice.208 In wheat, each of the three wheat genomes were mutated to entirely eliminate expression of the SSIIa gene product, Sgp-1 protein in one line 209 the result was reduced starch amounts and an altered starch structure. In rice, two classes of starch have been found. In Indica rices, the starch is of the long chain variety, while in Japonica, it is of the short chain variety.208 Genetic analysis showed that the mutation in Japonica rice led to a loss of starch synthase II.209 Thus, in higher plants, it seems that loss of SSII activity in dicots and SSIIa activity in monocots have the same results with respect to reduced starch content, due to a lowered amount of amylopectin and altered amylopectin chain size distribution. Thus, these genes may have the same function in starch biosynthesis. 

The iodine affinities, blue values, max, beta-amylolysis limits and branch chain length distributions are similar for the starch samples harvested at different stages (7 to 30 days DAF) of development of waxy rice grains,331 japonica rice328 and indica rice.332 The gelatinization temperature of maize starch increases from 12 to 24 DAF, but is reduced at 36 DAF.333...

Smyth (1988), using Indica rice, resolved two or three peaks of BE on an anion-exchange chromatography. Although the molecular weight of the BE seemed to be only about 40,000, activity was determined using the iodine assay and a crude extract, and amylase contamination or possible proteolysis apparently were not taken into account.

Metabolism studies conducted on 6 showed that 0-dealkylation of one heterocycle methoxy group was occurring in rice (Fig. 2.4.3) [47]. A comparison of metabolic degradation rates and activity on indica rice, japonica rice and bamyardgrass for 6 indicates that degradation rates explain the major differences observed in activity (Table 2.4.6). Other factors, such as site of uptake and transport, which are modulated by plant structure and metabolism, may contribute to additional rice selectivity observed for penoxsulam.
