A Natural Intuition Underlying Vernalization Case in Plants: Epigenetic
2016
Behcet İnal | Serdar Altıntaş
Plants have developed a number of monitoring systems to sense changes occurring in the environment and to coordinate their growth and development accordingly. Some plant groups have cold exposure requirement for a certain period to induce flowering. That process known as vernalization is case in point for mentioned systems. In many plants group, vernalization results in repression of floral repressor genes inhibiting floral transition. In this review, last epigenetic developments about vernalization mediated floral transition in Arabidopsis regarded as model organism for plants and other flowering plants will be discussed. Furthermore, similarity and differences in regulatory cycles in Arabidopsis and other flowering plants, changes in histone modifications at floral repressor loci and other epigenetic systems effective in vernalization will be discussed. To sum up, profound investigation of epigenetic mechanism behind the vernalization process plays an important role to decrease flowering-dependent yield losses.
