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 …

Alternative Poa Species As Permanent And Temporary Turfgrasses In The Transition Zone, Samuel Lucas Freshour

Masters Theses

As restrictions on water, fertilizer, and pesticide use increase, along with public pressure, turfgrass practitioners will need ways to meet the challenges of reduced inputs while still maintaining acceptable turf quality. Proper selection of turfgrass species and cultivars that are adapted to the climate, intended use, and level of expectation is the best and first line of defense for reduced input situations. The objective of this study was to evaluate alternative species from the bluegrass (Poa) genus for their performance as both permanent and temporary winter turfgrass species. In 2010 and 2011, 45 different treatments consisting of 37 different bluegrasses …
