Flower Petal Cell Walls: Changes Associated with Flower Opening and Senescence*
Flowers are prized as objects of great beauty and diversity, and are commercially valuable (~US$4.5 billion in international trade yearly) and highly perishable. Biologically, flower petals have an important role in the lifecycle of plants, as they protect immature reproductive structures, then provide the attraction and accessibility needed for pollination to occur. Flower petal cell wall cons...
متن کاملPETAL SENESCENCE IN CUT Tagetes erecta L. FLOWERS: ROLE OF PHENOLICS
Petals are an excellent model system for the study of fundamental aspects of senescence. The need of present study was felt with the aim to study the changes taking place during petal senescence in cut flowers of Tagetes erecta L. Estimation of total phenols was studied from first stage to senescent stage of Tagetes erecta L. The amount of total phenols had a decreasing trend with progressing s...
متن کاملUsing Gibberellins to Prevent Leaf Yellowing in Cut Lilies
Hybrid lilies are excellent cut flowers due to the availability of flowers with various colors and shapes. Extensive inter-species hybridization has resulted in numerous cultivars, and many new cultivars are introduced to the market each year. While the vigor and reliability of the crop has improved over the years, what has not changed is that the postharvest quality of the cut stem is an impor...
متن کاملIs petal senescence due to sugar starvation?
Senescence occurs at every stage of plant development. Shriveling of the cotyledons in young plants and the seasonal recurrence of leaf yellowing are obvious examples. Similarly, after pollination, petals have fulfilled their biological role and become senescent. Despite this ubiquity, however, the molecular events that initiate senescence have thus far remained a mystery. Thimann et al. (1977)...
متن کاملPhysiology and molecular biology of petal senescence.
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 degradation of macromolecules, but it is still unclear if it contributes to cell death. Depending on the species, petal senescence is controlled by ethylene or is independent of this hormone. EIN3-like (EIL) transcription facto...
