The information compiled in this volume represents the state-of the-art research and our understanding of plant cold hardiness in terms of molecular biol ogy, biochemistry, and physiology. The International Plant Cold Hardiness Seminar was the fifth of the series; it was first held in at the University of Minnesota, St. Paul, MN. Molecular genetics of frost hardiness and cold acclimation in Solanum species. By. .\ud Frost hardiness and cold acclimation were not correlated and variation for both traits\ud could be best explained by an additive-dominance model, with "additive" effects the\ud most important. Broad sense heritability was moderate to high ( Jenkins () found GENETICS OF COLD ACCLIMATION IN PLANTS TABLE 1 Wheat Chromosomes That Can Affect Frost Hardiness: Summary of Literature Chromosome 1A 1B 1D 2A 2B Reference(s) Fletcher (),Musich and Bondar' () Surkova (),Sutka and Rajki (,), Goujon et al.

MOLECULAR GENETICS OF FROST HARDINESS AND COLD ACCLIMATION IN SOLANUM SPECIES CHAPTER 1 INTRODUCTION AND LITERATURE REVIEW Introduction Potato is the world's fourth most important crop; however, it ranks first in yield per unit of land among the world's major food crops (F.A.O. Production Year Book, ).
In Solanum species, an association between palisade layer number and frost tolerance has been observed (Palta & Li ), while in B. napus cold acclimation‐associated enlargement of leaf mesophyll cells occurs (Stefanowska et al. ). Solanum tuberosum is a frost-sensitive species incapable of cold acclimation. A brief exposure to frost can significantly reduce its yields, while hard frosts can completely destroy entire crops. Cold Acclimation and Freezing Stress Tolerance: Role of Protein Metabolism cold hardiness cryobiology gene expression frost environmental physiology. The physiological and molecular mechanisms of tolerance to osmotic and ionic components of salinity stress are reviewed at the cellular, organ, and whole-plant level. Solanum commersonii, one of the most cold-hardy wild potatoes, can survive to about-5 °C pre-acclimation, and to as low as °C after becoming fully cold .
Relative to wild-type plants, ectopic AtCBF1 over-expression induced expression of COR genes without a cold stimulus in both species, and imparted a significant freezing tolerance gain in both species: 2 degrees C in S. tuberosum and up to 4 degrees C in S. commersonii. Cold-acclimation produced an increase in freezing tolerance of all cultivars (by lowering LT 50). Domat and Lecquest were found to have the highest cold-hardiness among the nine cultivars investigated. Ascolona, Gemlik, Hojoblanca had moderate cold-hardiness, while Samanli, Meski, Uslu and Manzanilla were more sensitive. Purchase Plant Cold Hardiness and Freezing Stress - 1st Edition. Print Book & E-Book. ISBN , This volume particularly addresses the cold acclimation, freezing, and other temperature-related stresses in plants. Frost Injury in Supercooled Leaves of Tuber-Bearing Solanum Species. DETERMINATION OF FROST HARDINESS AND FROST RESISTANCE The United States Department of Agriculture (USDA) established a system of climate zones based on the lowest mean minimum temperatures of the coldest month (Rehder ) in intervals of 10°F (°C) from Zone 1 (40°F, °C). Horticultural texts such as the.
