The Maize Seed Anatomy of the Mature Maize Seed
The pericarp consist in the transformed wall of the ovary that covers the seed and acts as a protection for the embryo and endosperm. It takes the place of the seed coats or integuments in the ordinary seeds, which in maize are reduced to unnoticeable remnants in the mature kernel. A thin, suberized nucellar membrane derived from the outer epidermal wall of the nucellus persists as a continuous...
متن کاملTissue-specific patterns of a maize Myb transcription factor are epigenetically regulated.
The maize p1 gene encodes a Myb-homologous regulator of red pigment biosynthesis. To investigate the tissue-specific regulation of the p1 gene, maize plants were transformed with constructs combining promoter and cDNA sequences of two alleles which differ in pigmentation patterns: P1-wr (white pericarp/red cob) and P1-rr (red pericarp/red cob). Surprisingly, all promoter/cDNA combinations produ...
متن کاملMovement of modulator in maize: a test of an hypothesis.
A model of Modulator movement (Greenblatt 1968) from one chromosomal site to another requires that all movements produce potential twin mutations within the affected cell lineage. From this model the prediction would be that (1) untwinned red and untwinned light-variegated sectors within the pericarp of medium-variegated maize must occur in equal frequency even though partners become lost, duri...
متن کاملA Stable Somatic Mutation to Colorless from Variegated Pericarp in Maize.
OLORLESS pericarp and cob is one of the least frequent mutant phenotypes C among the offspring of maize plants carrying the somatically unstable variegated pericarp allele, PV. BRAWN (1956) , for example, found only eight mutations to colorless pericarp and cob in contrast to 125 to red pericarp and cob(P") among 4575 offspring from the mating homozygous variegated times standard colorless (P""...
