The mode of abscisic acid (ABA) action, and its relations to drought adaptive responses in
particular, has been a captivating area of plant hormone research for much over a decade …

Petal senescence is reviewed, with the main emphasis on gene expression in relation to
physiological functions. Autophagy seems to be the major mechanism for large-scale …

The continuous formation of lateral roots is a vital part of establishing a root system and
enables plants to react with developmental plasticity to changing soil conditions. Evidence is …

Cytosolic hormone levels must be tightly controlled at the level of influx, efflux, synthesis,
degradation and compartmentation. To determine ABA dynamics at the single cell level …

Reactive oxygen species (ROS) play a key role in the regulation of many developmental
processes, including senescence, and in plant responses to biotic and abiotic stresses …

Rhizobia reside as symbiosomes in the infected cells of legume nodules to fix atmospheric
nitrogen. The symbiotic relation is strictly controlled, lasts for some time, but eventually leads …

A noninvasive, cell-autonomous reporter system was developed to monitor the generation
and distribution of physiologically active pools of abscisic acid (ABA). ABA response (abi1-1) …

Flowers are highly complex organs that have evolved to enhance the reproductive success
of angiosperms. As a key component of flowers, petals play a vital role in attracting …

The relatively brief postharvest life of most cut flowers and potted flowering plants can be
extended by a range of technologies. Studies have shown that vase life is negatively …

Rose (R osa hybrida) is one of the most important ornamental plants worldwide; however,
senescence of its petals terminates the ornamental value of the flower, resulting in major …
