In contrast to the majority of animal species, plants are sessile organisms and are, therefore, constantly challenged by environmental perturbations. Over the past few decades, our knowledge of how plants perceive environmental stimuli has increased considerably, e. In addition, it has recently been shown that plants can remember past environmental events and can use these memories to aid responses when these events recur. In this mini review, we focus on recent progress in determination of the epigenetic mechanisms used by plants under various environmental stresses. Epigenetic mechanisms are now known to play a vital role in the control of gene expression through small RNAs, histone modifications and DNA methylation. These are inherited through mitotic cell divisions and, in some cases, can be transmitted to the next generation. They therefore offer a possible mechanism for stress memories in plants.

Epigenetic memory in plants

Alterations in gene expression are essential during growth and development phases and when plants are exposed to environmental challenges. Stress conditions induce gene expression modifications, which are associated with changes in the biochemical and physiological processes that help plants to avoid or Stress conditions induce gene expression modifications, which are associated with changes in the biochemical and physiological processes that help plants to avoid or reduce potential damage resulting from these stresses. After exposure to stress, surviving plants tend to flower earlier than normal and therefore transfer the accumulated epigenetic information to their progenies, given that seeds, where this information is stored, are formed at a later stage of plant development. DNA methylation is correlated with expression repression. However, histone modulation, such as histone acetylation, methylation, and ubiquitination, can show distinct effects on gene expression.

Epigenetics

It seems that you're in Germany. We have a dedicated site for Germany. Epigenetics commonly acts at the chromatin level modulating its structure and consequently its function in gene expression and as such plays a critical role in plant response to internal and external cues.

Панк кивнул и расхохотался. - Похоже, ты облажался, приятель. - Но сейчас только без четверти. Двухцветный посмотрел на часы Беккера. Его лицо казалось растерянным.

 Куда. - В ее трахнутый Коннектикут.  - Двухцветный снова хмыкнул.  - Эдди места себе не находит.

Epigenetic Regulation in Plant Responses to the Environment

Ее снова сжали уже знакомые ей стальные руки, а ее голова была намертво прижата к груди Хейла.

Epigenetic memory for stress response and adaptation in plants.

Пора было отсюда вылезать. Дернул. Никакой реакции.

 Нам нужен этот предмет, - сказал Фонтейн.  - Где сейчас находится Халохот. Смит бросил взгляд через плечо.

 Вы отлично знаете это. Это Цифровая крепость. - Вот как? - снисходительно произнес Стратмор холодным как лед голосом.  - Значит, тебе известно про Цифровую крепость. А я-то думал, что ты будешь это отрицать. - Подите к черту.
