The role of TaABF1 in abscisic acid-mediated suppression of -amylase gene expression in cereal grains

The phytohormones gibberellin (GA) and abscisic acid (ABA) regulate important developments events in germinating seeds. Specifically, GA induces the expression of hyrolase genes, like the α-amylase gene Amy32b, which mobilizes starch reserves to be used by the embryo, and ABA suppresses this induction. Recent advancements identified ABA and GA receptors and key components in the signaling pathways, however, the mechanism of crosstalk between the hormones remains largely unknown. To further elucidate the mechanism of ABA suppression of GA-induced genes, we focused on the transcription factor TaABF1, a member of the ABA response element binding factor family. TaABF1 has been shown to physically interact with the SnRK2 kinase PKABA1 and overexpression of TaABF1 or PKABA1 can suppress Amy32b. We carried out particle bombardment experiments to investigate how TaABF1 suppresses Amy32b and how TaABF1 is activated by ABA. The role of TaABF1 in ABA-mediated suppression of Amy32b is more complicated than hypothesized. Unlike PKABA1, overexpression of TaABF1 did not cause a decrease of GAMyb expression and in fact resulted in an increase of GAMyb expression. When TaABF1 and GAMyb were simultaneously overexpressed in aleurone, the GAMyb induction of Amy32b was unaffected, indicating that the target of TaABF1 action must be upstream of GAMyb. Furthermore, TaABF1 and ABA demonstrated an additive effect on the suppression of Amy32b. Based on our findings, we propose a model in which PKABA1 activates two separate targets, one being TaABF1 which then modifies an unknown target upstream of GAMyb and the other being an unknown transcription factor that suppresses GAMyb transcription.

Change through Tradition in the Work of 'Zulu Sofola Rehearsal Presentation Outline

This paper highlights the struggle Nigerian playwright 'Zulu Sofola underwent to impart her message. She attempted to confront gender oppression through tradition without contradicting herself in her play, 'Wedlock of the Gods.' ‘Zulu Sofola wrote commentaries about social problems and the influence of Western culture. Her goal was to maintain a traditional framework in the face of encroaching Western perspectives. She advocated enacting change through tradition, irrespective of Western ideologies about change. Sofola focused on gender oppression as a social problem. She intended to address gender oppression rooted in tradition by teaching traditional customs to her audience in order for audiences to make informed and progressive decisions about what to change within traditional practices. Thus, her traditionalist approach to change requires cognizance and recognition of tradition as an initial step. Sofola argued against the influences of Westernization that shift the focus of change from confronting customs through tradition to confronting customs through Western ideology.
