Enabling Breeding For Fruitlet Freeze Tolerance In Peach, Ufuk Caglar
All Theses
Climate change is affecting the production of temperate fruit crops, with cold temperatures emerging as a critical abiotic stressor that limits plant growth and performance. Freeze damage, particularly in spring, has resulted in significant economic losses in peach production in the southeastern United States. Research efforts in peach and other Prunus species have primarily focused on studying dormancy-related traits associated with bloom time, such as chill and heat requirement, with fruitlet freeze tolerance not equally represented. Breeding for climate resilience in peach requires a combination of these traits to allow for late bloom via targeted chill requirement and high heat …

Peach (Prunus persica (L.) Batsch) fruit is a delicious summer treat appreciated for its sweet, juicy, and aromatic taste all over the globe. With only 44 calories and zero fat per fruit, peach has a great popularity among consumers and producers for its nutritional and economic value. Peach production is threatened by unpredictable climate changes, rising temperatures that reduce winter chill, especially in the warmer growing areas, resulting in fruit and yield loss. Therefore, it is necessary to develop cultivars that are resilient to environmental changes. Peach breeding takes a long time, and this process can benefit from the …

Fluctuating climate over the last 2 million years (MY) has repeatedly caused latitudinal shifts in species distributions, fueling the hypothesis that the glacial-interglacial dynamics of the Pleistocene could have driven regional genetic differentiation and potentially speciation. For species whose distributions spanned the entire North Pacific, regional extinction of northern populations during cooler glacial periods may have resulted in isolation and genetic differentiation of eastern and western populations. To test this hypothesis, I gathered genetic data from a rocky shore intertidal gastropod, Nucella lima, whose current (i.e. warm interglacial) distribution spans the entire North Pacific. Mitochondrial DNA sequences are genetically structured …
