Here's a nice summary from Scientific American: http://www.scientificamerican.com/article.cfm?id=can-epigentics-help-crops-adapt-to-climate-change
sonia ramos's comment, March 8, 2013 4:19 AM
Thanks for the Scientific American link. I do not work on it but I found it fascinating. Evolution and adaptation throgh epigenetics. And interesting thought about epigenetics like diversity source, should be a good research line

Defense Priming: An Adaptive Part of Induced Resistance | Annual Review of Plant Biology

Defense Priming: An Adaptive Part of Induced Resistance | Annual Review of Plant Biology | Cool tidbits about plants | Scoop.it
Priming is an adaptive strategy that improves the defensive capacity of plants. This phenomenon is marked by an enhanced activation of induced defense mechanisms. Stimuli from pathogens, beneficial microbes, or arthropods, as well as chemicals and abiotic cues, can trigger the establishment of priming by acting as warning signals. Upon stimulus perception, changes may occur in the plant at the physiological, transcriptional, metabolic, and epigenetic levels. This phase is called the priming phase. Upon subsequent challenge, the plant effectively mounts a faster and/or stronger defense response that defines the postchallenge primed state and results in increased resistance and/or stress tolerance. Priming can be durable and maintained throughout the plant’s life cycle and can even be transmitted to subsequent generations, therefore representing a type of plant immunological memory.

The plant perceptron connects environment to development

The plant perceptron connects environment to development | Cool tidbits about plants | Scoop.it
Plants cope with the environment in a variety of ways, and ecological analyses attempt to capture this through life-history strategies or trait-based categorization. These approaches are limited because they treat the trade-off mechanisms that underlie plant responses as a black box. Approaches that involve the molecular or physiological analysis of plant responses to the environment have elucidated intricate connections between developmental and environmental signals, but in only a few well-studied model species. By considering diversity in the plant response to the environment as the adaptation of an information-processing network, new directions can be found for the study of life-history strategies, trade-offs and evolution in plants.

Vesicles versus Tubes: Is Endoplasmic Reticulum-Golgi Transport in Plants Fundamentally Different from Other Eukaryotes?

Vesicles versus Tubes: Is Endoplasmic Reticulum-Golgi Transport in Plants Fundamentally Different from Other Eukaryotes? | Cool tidbits about plants | Scoop.it

I really like this approach to writing review summary. The question is, how does material move between the ER and Golgi - through vesicles or through tubes? The answer isn't simple, as there are data to support both answers, and other possibilities as well. So, "in this article, four leading plant cell biologists attempted to resolve this issue. Unfortunately, their opinions are so divergent and often opposing that it was not possible to reach a consensus. Thus, we decided to let each tell his or her version individually."
