Groundwater-dependent ecosystems face a greater threat of pollution. In many cases groundwater can become polluted through toxins, or even just excessive amounts of certain nutrients seeping down to the water table. This polluting of the groundwater can have many different effects on the related ecosystems in the case of an estuary in Cape Cod it was noted that an influx of new nitrogen had come from septic tank fields in the groundwater’s flow path. Increased levels of nitrogen in aquatic ecosystems can cause eutrophication which is the process of excessive introduction of nutrients causing an abundance of plant growth which can result
Epigenetics of plant growth and development or other component of DNA. Long non-coding RNA often complement functional regions of DNA with overlaps or antisense (Kung et al. 2013). To direct transcriptional silencing, a non-coding RNA will associate with a polycomb group protein which to tether it to a specific gene for silencing (Kleinmanns et al. 2014). Germination is the early growth of a plant from a seed. Meanwhile, dormancy precedes germination and serves to preserve a seed until conditions are receptive towards growth. The transition from dormancy to germination seems to depend on the removal of factors inhibiting growth. There are many models for germination which
