Leaf senescence can impact crop production by either changing photosynthesis duration, or
by modifying the nutrient remobilization efficiency and harvest index. The doubling of the …

Everybody is familiar with the visual aspects of plant senescence. Color changes occurring
in senescing leaves are, however, only one (albeit striking) symptom of the senescence …

The transition from juvenility through maturation to senescence is a complex process that
involves the regulation of longevity. Here, we identify JUNGBRUNNEN1 (JUB1), a hydrogen …

The Arabidopsis thaliana protein nitric oxide synthase1 (NOS1) is needed for nitric oxide
(NO) synthesis and signaling during defense responses, hormonal signaling, and flowering …

The initiation, progression, and natural variation of autumn senescence in European aspen
(Populus tremula) was investigated by monitoring chlorophyll degradation in (1) trees …

Unlike animals, plants amply convert melatonin into 2-hydroxymelatonin (2-OHM) and cyclic
3-hydroxymelatonin (3-OHM) through the action of melatonin 2-hydroxylase (M2H) and …

Different parameters which vary during the leaf development in sunflower plants grown with
nitrate (2 or 20 mM) for a 42‐day period have been determined. The plants grown with 20 …

What controls the length of life is one of the fundamental biological questions that has been
puzzling scientists for centuries. Plants have many life-forms and differ greatly in the …

Nitric oxide (NO) has been known to preserve the level of chlorophyll (Chl) during leaf
senescence. However, the mechanism by which NO regulates Chl breakdown remains …

Crop losses caused by climate change and various (a) biotic stressors negatively affect
agriculture and crop production. Therefore, it is vital to develop a proper understanding of …
