Swiatek et al. [8] have demonstrated that ABA can arrest cell cycle progression
at the initial phase of cell division. Amaral Da Silva and his associates [25] have shown that ABA inhibits
the abundance of microtubule, microtubule-reorganization and DNA replication in germinating coffee seeds.
Therefore the negative effects of ABA on seed germination can be attributed to inhibition of DNA synthesis,
spindle formation, chromatid separation, decreased transcription rate, rRNA gene hypoacetylation [26]
