“…The movement of Ca 2ϩ down a concentration gradient through Ca 2ϩ -permeable channels from extra-or intracellular stores represents one important mode of signal transduction of external stress signals (Bush, 1995;Sanders et al, 1999). Therefore, we investigated the role of calcium on the stress and ABA induction of Ppc1 transcripts by testing various calcium chelators, ionophores, and inhibitors of calcium ATPase activity.…”

A rapid, semiquantitative reverse transcriptase-polymerase chain reaction assay was developed to investigate signal transduction events involved in the induction of Crassulacean acid metabolism (CAM) in detached common ice plant (Mesembryanthemum crystallinum) leaves. Transcript abundance of Ppc1, a gene encoding the CAM-specific isoform of phosphoenolpyruvate carboxylase, increased rapidly in response to osmotic stress (dehydration and mannitol), ionic stress (NaCl), and exogenous abscisic acid treatment, but failed to accumulate in response to exogenous cytokinin or methyl jasmonate. Stress-induced accumulation of Ppc1, GapC1, and

“…Because Ca 2ϩ is relatively immobile in the cytosol and quickly becomes associated with Ca 2ϩ -binding proteins, the degree of Ca 2ϩ saturation within the cell even after a substantial Ca 2ϩ influx is most pronounced in microdomains that are localized near the pore of the channel through which cation influx occurs (57). Recent evidence indicates that Ca 2ϩ -binding proteins (calmodulin, Ca 2ϩ -dependent protein kinases (CDPKs), phosphatases, heterotrimeric G-proteins, etc.)…”

“…Calcium is an essential mineral element that plays an important role in enzymatic and hormonal processes, preserving the integrity of membranes and cell walls, improving the storage quality of table grapes and other fruits and acting in plant cell signaling (Sanders et al, 1999). In general, increasing the calcium content of grape berries, particularly the skin, lowers berry susceptibility to B. cinerea infection (Chardonnet and Donèche, 1995;Miceli et al, 1999).…”

Gray mold caused by Botrytis cinerea limits grape production in Chile

by Botrytis cinerea is a major disease of grapes (Vitis vinifera) that substantially reduces the yield and quality of grape production in temperate and humid regions of the world. B. cinerea is a necrotrophic fungus that attacks the non-lignified aerial organs of grapes; in particular, berries are highly susceptible during ripening. The polycyclic nature and exponential progress exhibited by GM at the beginning of the its epidemic, as well as the abundant inoculum production, the high dissemination efficiency, the wide host range and the high genetic variability of B. cinerea, explain the difficulties encountered in attempting to control GM. At present, integrated disease management, including cultural and chemical control, is the main control strategy. These control measures can be used to reduce the initial inoculum or to lower the disease infection rate. However, control measures that reduce the infection rate are the most effective means of controlling GM. Important progress toward understanding the complexity of the biology and epidemiology of this pathogen has occurred in recent decades. This has allowed the improvement and development of more effective and sustainable control strategies against B. cinerea. This review article provides a recent update regarding grape GM, with special emphasis on Chilean production conditions.
