Modulation Of Plant Immunity During The Establishment Of The Nitrogen-Fixing Symbiosis, Miriam Hernandez-Romero

Doctoral Dissertations

Nitrogen is essential for plant tissue growth but is often a limited resource in soils. Many legumes overcome this limitation by entering a symbiotic association with soil microbes, called rhizobia, which provide nitrogen to the plant while rhizobia receive fixed carbon. To successfully form a symbiosis, the host and symbiont exchange a series of molecular signals. One major obstacle during this interaction is the host's innate immune system, which becomes active upon rhizobial detection. It is therefore the main focus of this thesis to identify the mechanisms that modulate host immunity. In the subsequent chapters, we focus on a rhizobial …

Date Of Planting And Nitrogen Management For Malt Barley Production In The Northeast Usa, Arthur Siller, Masoud Hashemi, Alexandra Smychkovich, Caroline Wise, Heather Darby

Data and Datasets

There is an increasing market for locally grown malting barley (Hordeum vulgare L.) in the Northeast US. Malting barley must meet certain quality standards for acceptability in the brewing market. Up-to-date recommendations are needed regionally for adaptation to ongoing climate change. A two-year field experiment was conducted to assess the interactive influence of three dates of planting (5 Sept., 15 Sept, and 25 Sept.), two levels of fall N (0 or 28 kg ha^-1), and three levels of spring N (28, 50.5, and 73 kg ha^-1). No significant difference was detected in grain yield amongst …

Chipilin (Crotalaria Longirostrata) is a leguminous plant native to Central America and Southern Mexico and used in the preparation of traditional dishes in this region. Starting in 2009, farmers in Massachusetts have been growing chipilin with a weekly production of 800 kg∙ha^-1. However, as much as 300 kg∙ha^-1 of nitrogen has been …
