ANALYSIS OF GENES CONTROLLING PEROXIDASE ISOZYMES IN <i>ORYZA SATIVA</i> AND <i>O. PERENNIS</i>

EXPRESSION OF ALLELIC PEROXIDASE ISOZYMES IN HETEROZYGOTES OF <i>ORYZA PERENNIS</i>

“…The F1 showed a weak 2 A and two major bands 3 A and 4 A. Band 3 A was intermediate between 2 A and 4 A in mobility, and it must have been dimeric hybrid band derived from the monomeric subunits of dimeric isozymes 2 A and 4 A. Mobilities of these three bands were identified with those of 2 A, 3 A and 4 A bands reported for leaf blade and leaf sheath (Shahi et al 1969).…”

“…The heterozygote Pe2A/Pe4A showed a hybrid band 3 A in certain organs, i.e., leaf blade and leaf sheath (Shahi et al 1969), and also in lemma and palea. They showed organ-specific differences in the relative intensity of the three isozyme bands.…”

GENETIC CONVERGENCE OF THE SPECIFIC ACID PHOSPHATASE ZYMOGRAMS IN <i>ORYZA SATIVA</i>

“…The former were W107 (P1i annual) and W1294 (P2, perennial), both mentioned in our previous papers (Shahi et al 1969b;Endo 1971), The latter were 108 (P3, Indica type) and T65 (P4, Japonica type). These were pure lines, except for W1294 which was homozygous for the isozymic characters examined.…”

A SURVEY OF VARIATIONS IN PEROXIDASE, ACID PHOSPHATASE AND ESTERASE ISOZYMES OF WILD AND CULTIVATED <i>ORYZA</i> SPECIES

“…As 3A is a hybrid dimer band due to 2A 4A (Shahi et al 1969), its occurrence in some perennis strains indicates their heterozygosity.…”
