Accumulation of silicon and arrangement and shapes of silica bodies in corn leaves

F. A. Andrade, O. Júnior, A., Andrade, C. G. T. J., and Miglioranza, E., “Accumulation of silicon and arrangement and shapes of silica bodies in corn leaves”, vol. 13, pp. 1690-1696, 2014.

Different plant species have different levels and locations of silicon accumulation in their tissues, and may or may not have silica bodies. Grasses usually accumulate these bodies, which may have different shapes depending on the genotype. Besides, this element can be beneficial to crops. The present study aimed to examine the forms and locations of silicon accumulation, as well as silicon content, in flag leaves of corn (Zea mays L.). This was a field experiment with two cultivars of corn: Coodetec 384 and Pioneer BG7065H.

Preponderance of GC-rich sites in silver-stained nucleolus organizing regions of Rita rita (Hamilton) and Mystus gulio (Hamilton) (Bagridae, Pisces), as revealed by chromomycin A3-staining technique and scanning electron microscopic studies

J. K. Das and Khuda-Bukhsh, A. R., “Preponderance of GC-rich sites in silver-stained nucleolus organizing regions of Rita rita (Hamilton) and Mystus gulio (Hamilton) (Bagridae, Pisces), as revealed by chromomycin A3-staining technique and scanning electron microscopic studies”, vol. 6, pp. 284-291, 2007.

The karyotypes of two species of catfish, Rita rita (Hamilton) (2n = 54; 14m + 34sm + 6st; NF = 102) and Mystus gulio (Hamilton) (2n = 58; 30m + 12sm + 2st + 14t, NF = 100) were studied through Giemsa-, silver- and chromomycin A3-staining techniques. The silver-stained karyotypes in both sexes of R. rita and M. gulio revealed that the nucleolus organizing regions were located terminally at the shorter arms (Tp) of one pair of submetacentric chromosomes, placed at positions Nos.
