The tomato (Lycopersicon esculentum) chloroplast small heat shock protein (sHSP), HSP21, is induced by heat treatment in leaves, but also under normal growth conditions in developing fruits during the transition of chloroplasts to chromoplasts. We used transgenic tomato plants constitutively expressing HSP21 to study the role of the protein under stress(More)
Partially tree-ripened ripe fruit of peach (Prunus persica L.) were stored for 1-4 weeks at 5 degrees C and then ripened at 20 degrees C for 3 d to induce chilling injury. With increasing cold storage the incidence and severity of mealiness symptoms increased progressively, manifested as reduced quantities of free juice and internal flesh browning. Relative(More)
Wide international interest in heat treatments for maintenance of postharvest quality, disease control, and as a quarantine technology, was reflected in the range of papers presented at this BARD Workshop on Postharvest Heat Treatments. Heat treatments are currently used commercially in several countries, for example as hot water dips, hot water brushing(More)
Single nucleotide polymorphisms (SNPs) were used to construct an integrated SNP linkage map of peach (Prunus persica (L.) Batsch). A set of 1,536 SNPs were evaluated with the GoldenGate® Genotyping assay in two mapping populations, Pop-DF, and Pop-DG. After genotyping and filtering, a final set of 1,400 high quality SNPs in Pop-DF and 962 in Pop-DG with(More)
Both delayed storage (DS) of nectarine (Prunus persica cv. Flavortop) fruits held for 48 h at 20°C before storage, and controlled atmosphere (CA) storage, fruits stored at 10% CO2, 3% O2, alleviated or prevented chilling injury manifested as woolliness in nectarine fruits stored for 4 or 6 weeks at 0°C. Control fruits showed 80 and 100% woolliness during(More)
Peaches (Prunus persica cv. Hermoza) were stored at 0C in regular air (RA) or in controlled atmosphere (CA 10% CO2, 3% O2) for 4 weeks and then ripened for 4 days at 20 degrees C. Woolliness developed in the regular air stored fruit while the controlled atmosphere stored fruit ripened normally. In the woolly fruit symptoms of the disorder were greater in(More)
Cold storage induces chilling injury (CI) disorders in peach fruit (woolliness/mealiness, flesh browning and reddening/bleeding) manifested when ripened at shelf life. To gain insight into the mechanisms underlying CI, we analyzed the transcriptome of ‘Oded’ (high tolerant) and ‘Hermoza’ (relatively tolerant to woolliness, but sensitive to browning and(More)
Dehydrins (DHNs; late embryogenesis abundant D-11) are a family of plant proteins induced in response to environmental stresses such as water stress, salinity and freezing or which occur during the late stages of embryogenesis. Previously, it was reported that citrus contains a small gene family encoding a unique class of dehydrins that differs from most(More)
Many aspects of the treatment for adolescent depression are still uncertain. However, our body of knowledge continues to accumulate, and our approaches continue to be refined. When we remember that 40 years ago the field was still arguing about the existence of depression in youth, it is clear that significant progress has been made. Recent controversies(More)
