  1. sin1 (short integement)
    • Polarity Mutant
    • Affects ovule formation
  2. gnom/emb30
    • Polarity Mutant
    • Fail to establish apical-basal polarity
  3. mp (monpteros)
    • Segment Deletion Mutant
    • Lack basal region
  4. gk (gurke)
    • Segment Deletion Mutant
    • Lack apical region
  5. kn (knolle)
    • Radical Axis Mutant
    • Appears to not have epidermal layer. It does have it but it is disrupted by misoriented and abnormal cell division.
  6. Male Sterile Mutant
    • Entire male organ is messed up.
    • Least useful for studying
  7. Microsporogenesis Mutant
    Microsporogenesis is messed up
  8. Male Gametophyte Mutant
    Can't release microspore when produced
  9. RNA Interference Genes In Plants
    • 1. Arrgonauta
    • 2. Dicer
  10. Ovule Development Mutations
    bel1- Fails to form integement
  11. 3 Kinds of Apoximis (Sexual Reproduction In Plants)
    • 1. Diplospory
    • 2. Apospory
    • 3. Adventitious Embryo
  12. Diplospory
    No meiosis of megaspore. Results in 2n egg cell which acts as a zygote
  13. Apospory
    2n cell from ovule undergoes sporophyte genesis
  14. Adventitious Embryo
    Single cell forms adventitious embryo (2n). Doesn't create embryo sac
  15. FM4-64
    • Pollen Tube Growth Marker
    • Binds vessicle proteins
  16. GFP-HDEL
    • Pollen Tube Growth Marker
    • Binds Endoplasmic Reticulum
  17. GFR-Rab2
    • Pollen Tube Growth Marker
    • Binds golgi
  18. Arabinogalactin-Rich Glycoproteins
    Guide pollen tube to embryo sac
  19. Gametic System Self Incompatability
    • Determined by genotype of male gametophyte
    • Same allele = no fertilization
  20. Sporophytic System Self Incompatability
    • Determined by genotype of the sporophyte that gives rise to the pollinating male gametophyte
    • No alleles can be the same
  21. bio1
    • Embryo Lethal Mutant
    • Biotin defficient mutant (Arabadopsis)
  22. Raspberry
    • Embryo Lethal Mutant
    • Histogenesis in absense of organogenesis (Arabadopsis)
  23. dek
    • Embryo Lethal Mutant
    • Embryo and endosperm defective (maize)
  24. emb
    • Embryo Lethal Mutants
    • embryo defective (maize)
