Calmodulin Like 38 Is Required For Autophagy Of Hypoxia-Induced Cytoplasmic Rna Granules In Arabidopsis Thaliana, Sterling Field
Calmodulin Like 38 Is Required For Autophagy Of Hypoxia-Induced Cytoplasmic Rna Granules In Arabidopsis Thaliana, Sterling Field
Doctoral Dissertations
In response to the energy crisis resulting from submergence stress and hypoxia, the model plant Arabidopsis thaliana limits non-essential mRNA translation, and accumulates cytosolic stress granules. Stress granules are phase-separated mRNA-protein particles that partition transcripts for various fates: storage, degradation, or return to translation after stress alleviation. Another response by the plant cell to low oxygen stress is the induction of the turnover pathway autophagy. Stress granule regulation by autophagy occurs by a ‘granulophagy’ pathway in yeast and mammalian systems through which parts or whole stress granules are degraded. Whether this occurs in plants has not been investigated.

Erecta Family Genes Regulate The Shoot Apical Meristem And Organ Formation, Daniel A. Degennaro
Erecta Family Genes Regulate The Shoot Apical Meristem And Organ Formation, Daniel A. Degennaro
Doctoral Dissertations
Plants are sessile and must adjust their organ growth to their environments. A reservoir of stem cells in the shoot apical meristem (SAM) supplies cells for differentiation into organs. The SAM must balance organ production with stem cell maintenance. The ERECTA family (ERfs) encodes the leucine-rich repeat receptor-like kinases ERECTA (ER), ERECTA-LIKE 1 (ERL1), and ERL2. ERf signaling regulates organ initiation and stem cell maintenance. Results presented in this work include the following:
1) WUSCHEL (WUS) and CLAVATA3 (CLV3) make up a negative feedback loop to maintain SAM size. WUS and CLV3 expression localization is critical for …
Regulation Of Plasmodesmata By Specialized Metabolites Glucosinolates In Arabidopsis Thaliana, Jessica C. Fernandez
Regulation Of Plasmodesmata By Specialized Metabolites Glucosinolates In Arabidopsis Thaliana, Jessica C. Fernandez
Doctoral Dissertations
Communication is an essential component to all living organisms. In
plants, the additional cell wall surrounding each cell adds a layer of complexity
not observed in animals. To overcome the literal wall separating cells, plants
have evolved specialized pores to connect adjacent cells. Plasmodesmata (PD)
allow plants to have a continuous cytoplasm between cells. Although
plasmodesmata may appear simple and lack regulation, their structural
components and their regulatory machinery is complex and not well understood.
Organelle-to-nucleus-to-plasmodesmata signaling (ONPS) have been worked as
a leading model for a possible regulatory mechanism. Many of the details of
organelle-to-nucleus retrograde signaling pathways have …
