-In 1996, the USDA-Natural Resources Conservation Service (NRCS) Jamie L. Whitten Plant Materials Center (PMC) released three locally collected, source identified wetland plants. Indian Bayou source powdery thalia (Thalia dealbata Fraser ex Roscoe) and Leflore source creeping burhead [Echinodorus cordifolius (L.) Griseb.] were collected in the Mississippi Delta and Leaf River source woolgrass [...

Fennel (Foeniculum vulgare Mill.) is widely cultivated for its edible, strongly-flavored leaves, fruits, seeds and medicinal uses. As the wild and cultivated plants are influenced by environmental stresses, the effects of salt (25, 50 and 75 mM NaCl), nitrogen and iron deficiency (0 N, 0.5 N of Hoagland’s solution, 0 Fe and 0.5 Fe of Hoagland’s solution), 2°C cold (2, 3 and 4 h) and drought (3,...

Ischemia-reperfusion (I-R) injury after liver transplantation (LT) induces intra- and/or extrahepatic nonanastomotic ischemic-type biliary lesions (ITBLs). Subsequent bile duct stricture is a significant cause of morbidity and even mortality in patients who underwent LT. Although the pathogenesis of ITBLs is multifactorial, there are three main interconnected mechanisms responsible for their fo...

Calmodulin-like (CML) proteins are important Ca(2+) sensors, which play significant role in mediating plant stress tolerance. In the present study, cold responsive calmodulin-like (ShCML44) gene was isolated from cold tolerant wild tomato (Solanum habrochaites), and functionally characterized. The ShCML44 was differentially expressed in all plant tissues including root, stem, leaf, flower and f...

Cold tolerance is an important breeding target in rice production. We studied quantitative trait loci (QTLs) controlling cold tolerance at germination (CTG) and early seedling (CTS) stages, using recombinant inbred lines derived from a japonica × indica cross. CTG was evaluated based on the percentage rate of germination at 15 °C for 12 days after pre-incubation of imbibed seeds at 20 °C for 2 ...

BACKGROUND AND AIMS The shrub Viburnum tinus is widely distributed in mattoral vegetation of the Mediterranean basin. The purpose of the present study was to classify the seed dormancy type and examine the requirements for embryo growth, root protrusion and shoot emergence. METHODS Overwintered fruits were collected in western Spain in April 2001 and prepared in three ways: entire pericarp wa...

This work evaluated the effect of seed size and morphology on the development and biomass of durum wheat seedlings. Three different seed-grading sizes selected by sieving were used in glasshouse experiments, and a set of three developmental and 23 biomass-related indices were measured on eight genotypes, at two moisture levels. The influence of seed size on seedling development was studied at h...

Kidney transplantation is the preferred and definitive treatment for end-stage renal disease (ESRD), and kidneys from deceased donors are a major source for it. These kidneys are routinely cold stored to prolong viability, which, however, when prolonged can cause injury, resulting in reduced graft function and survival. Recent experimental studies have identified the release of iron and free ra...

Cucumber is a warm season crop that suffers from chilling injury at temperatures below 10°C. In recent years, jasmonates have been used for reduction of chilling injuries in plants. An experiment was, therefore, conducted to test whether methyl jasmonate (MeJA) application at various concentrations (0, 0.05, 0.1 and 0.15 mM) through seed soaking or foliar spray would protect cucumber seedlings,...

laboratory and field experiments were conducted to investigate the relationships between germination characteristics and field emergence in produced seeds of soybean cultivars as affected by under three different soil moisture conditions. the treatments are included water stress [irrigation plants after 50 (normal irrigation), 100 (mild stress), 150 (severe stress) mm evaporation from class a p...
