Adaptation to altitude affects the senescence response to chilling in the perennial plant Arabis alpina
In annual plants with determinate growth, sugar accumulation signals high carbon availability once growth has ceased, resulting in senescence-dependent nutrient recycling to the seeds. However, this senescence-inducing effect of sugars is abolished at cold temperature, where sugar accumulation is important for protection. Here, natural variation was exploited to analyse the effect of chilling o...
متن کاملAa TFL1 confers an age-dependent response to vernalization in perennial Arabis alpina.
Flowering of many plants is induced by environmental signals, but these responses can depend on the age of the plant. Exposure of Arabidopsis thaliana to vernalization (winter temperatures) at germination induces flowering, whereas a close perennial relative Arabis alpina only responds if exposed when at least 5 weeks old. We show that vernalization of these older A. alpina plants reduces expre...
متن کاملPEP1 of Arabis alpina Is Encoded by Two Overlapping Genes That Contribute to Natural Genetic Variation in Perennial Flowering
Higher plants exhibit a variety of different life histories. Annual plants live for less than a year and after flowering produce seeds and senesce. By contrast perennials live for many years, dividing their life cycle into episodes of vegetative growth and flowering. Environmental cues control key check points in both life histories. Genes controlling responses to these cues exhibit natural gen...
متن کاملComparison of signaling interactions determining annual and perennial plant growth in response to low temperature
Low temperature inhibits plant growth despite the fact that considerable rates of photosynthetic activity can be maintained. Instead of lower rates of photosynthesis, active inhibition of cell division and expansion is primarily responsible for reduced growth. This results in sink limitation and enables plants to accumulate carbohydrates that act as compatible solutes or are stored throughout t...
متن کاملMuslim Intellectuals and the Perennial Philosophy in the Twentieth Century
This paper will examine how Muslim intellectuals, as a result of their attachment to the doctrine of Divine Unity (taw¤hīd), the Quran, Sunnah of the Prophet Muhammad, and the doctrines and methods of Sufism, were largely responsible for the restating of the perennial philosophy in the West in the twentieth century. The article consists of four sections: an introduction to the term 'philosophia...
