Expanded turn conformations: Characterization and sequence-structure correspondence in alpha-turns with implications in helix folding
(WILEY-BLACKWELL,, 2004-05-01)Like the beta-turns, which are characterized by a limiting distance between residues two positions apart (i, i+3), a distance criterion (involving residues at positions i and i+4) is used here to identify a-turns from a ... -
Anther culture and plant regeneration in sugarcane (Saccharum officinarum)
(ELSEVIER, 2003-09)Anthers of Saccharum officinarum clone I 273-91 with microspores at mid uninucleate stage, responded to callusing within 60 days after plating on MS medium supplemented with sucrose (3%), 2, 4-D (2 mg/l) and coconut milk ... -
