  • determining if a sequence has ZmADA2 activity can be assayed by monitoring histone acetylation in in vitro assays (Balasubramanian, R., et al., (2002) J Biol Chem 277:7989-95).
  • methods to assay for a modulation of transcriptional activity can include monitoring for an alteration in the phenotype of the plant. For example, as discussed in further detail elsewhere herein, modulating the level of a ZmADA2 polypeptide can result in abnormal flower formation or alterations of yield. Methods to assay for these changes are discussed in further detail elsewhere herein.
  • the T m is the temperature (under defined ionic strength and pH) at which 50% of a complementary target sequence hybridizes to a perfectly matched probe. T m is reduced by about 1 °C for each 1% of mismatching; thus, T m , hybridization, and/or wash conditions can be adjusted to hybridize to sequences of the desired identity. For example, if sequences with >90% identity are sought, the T m can be decreased 10 0 C.
  • stringent conditions are selected to be about 5°C lower than the thermal melting point (T m ) for the specific sequence and its complement at a defined ionic strength and pH.
  • Computer implementations of these mathematical algorithms can be utilized for comparison of sequences to determine sequence identity. Such implementations include, but are not limited to: CLUSTAL in the PC/Gene program (available from Intelligenetics, Mountain View, California); the ALIGN program (Version 2.0) and GAP, BESTFIT, BLAST, FASTA, and TFASTA in the GCG Wisconsin Genetics Software Package, Version 10 (available from Accelrys Inc., 9685 Scranton Road, San Diego, California, USA).

  • the polynucleotides of the present invention may also be used in the sense orientation to suppress the expression of endogenous genes in plants.
  • Methods for suppressing gene expression in plants using polynucleotides in the sense orientation are known in the art.

  • the plates with callus are incubated in the dark at 27-28°C for 3-5 days. Prior to bombardment, the filters with callus are transferred to CM supplemented with 0.25 M mannitol and 0.25 M sorbitol for 3 hr in the dark. The petri dish lids are then left ajar for 20-45 minutes in a sterile hood to allow moisture on tissue to dissipate.
  • Plants were also passed through a root-imaging system that digitally photographs the root morphology and mass from the base of the clear-bottom pots. Plant above-ground area and root mass were determined by counting the total number of pixels from plant parts discriminated from the background. The above-ground value was averaged for the pictures taken on the same time point from the different angles and was converted to a physical surface value expressed in square mm by calibration. Experiments have shown that the above-ground plant area, which corresponds to the total maximum area, measured this way correlates with the biomass of plant parts above-ground.

Abstract

L'invention concerne des compositions et des méthodes pour moduler le développement des organes floraux, la formation des feuilles, le phototropisme, la dominance apicale, le développement des fruits et l'initiation des racines, ainsi que pour augmenter le rendement d'une plante. Ces compositions comprennent une séquence ZmADA2. Les compositions de l'invention comprennent des séquences d'acides aminés et des séquences nucléotidiques choisies parmi les séquences SEQ ID NO: 1, 2, 4, 5, 8, 9, 10, 11 et 12, ainsi que des variants et des fragments de celles-ci. Les séquences nucléotidiques codant pour ZmADA2 sont situées dans des constructions d'ADN en vue d'une expression dans une plante d'intérêt. L'invention concerne également des méthodes destinées à moduler le niveau d'une séquence ZmADA2 dans une plante ou une partie d'une plante. Ces méthodes consistent à introduire, dans une plante ou une partie d'une plante, un polynucléotide hétérologue comprenant une séquence ZmADA2 de l'invention. Le niveau du polypeptide ZmADA2 peut être augmenté ou abaissé. Une telle méthode peut permettre d'augmenter le rendement de plantes. Dans un mode de réalisation, elle permet d'augmenter la production de grains dans des céréales.
