Large (A) and small (B) granules of wheat starch were separated and their morphological, thermal, structural and pasting properties were investigated. The pasting properties of starches from two wheat varieties showed significant differences. For wheat variety C-306, the unfractionated starch showed higher peak, trough, breakdown, final, and setback viscosities than the starch isolated from wheat variety WH-147. On the contrary, unfractionated starch of variety WH-147 has higher pasting temperature than the starch of the variety C-306. Differential scanning calorimetry results showed that unfractionated starch exhibited the higher gelatinization enthalpy, peak and conclusion temperatures than the isolated A- and B-starch granules from both the varieties. Scanning electron microscopy results revealed that large A-granules appeared to be smooth and displayed disk or lenticular shape having diameter 13-35 μm, while B-granules showed a spherical shape with diameter of 2-6 μm. The variations in structures and content would result in starch granules with different chemical and physical properties.

The MDM2 overexpression noticed in plexiform ameloblastoma, follicular ameloblastoma with granular cell changes and acanthomatous ameloblastoma when compared to simple unicystic and desmoplastic ameloblastoma suggest a relatively enhanced proliferative phenotype of these solid multicystic variants of ameloblastomas. On overall comparison, higher expression was noted in ameloblastomas when compared to AOT. This indicates differences in the aggressive nature between these two groups of odontogenic tumors favoring the perception of a greater aggressive nature of ameloblastomas.

In Brassica oleracea , heterosis is the most efficient tool providing impetus to hybrid vegetable industry. In this context, we presented the first report on identifying superior heterotic crosses for yield and commercial traits in cauliflower involving cytoplasmic male sterile (CMS) and doubled haploid (DH) lines as parents. We studied the suitability of genomic-SSRs and EST-SSRs based genetic distance (GD) and agronomic trait based phenotypic distance (PD) for predicting heterosis in F 1 hybrids using CMS and DH based parents. 120 F 1 hybrids derived from 20 Ogura based CMS lines and 6 DH based testers were evaluated for 16 agronomic traits along with the 26 parental lines and 4 commercial standard checks. The genomic-SSRs and EST-SSRs based genetic structure analysis grouped the 26 parental lines into 4 distinct clusters. The CMS lines Ogu118-6A, Ogu33A, Ogu34-1A were good general combiner for developing early maturity hybrids. The SCA effects were significantly associated with heterosis suggesting non-additive gene effects for the heterotic response of hybrids. Less than unity value of σ 2 A/D coupled with σ 2 gca /σ 2 sca indicated the predominance of non-additive gene action in the expression of studied traits. The correlation analysis of genetic distance with heterosis for commercial traits suggested that microsatellites based genetic distance estimates can be helpful in heterosis prediction to some extent.
