Occurrence and tolerance mechanisms of seed cracking under low temperatures in soybean (Glycine max)
In soybean, occurrence of, or tolerance to, seed cracking under low temperatures may be related to the presence or absence, respectively, of proanthocyanidin accumulation in the seed coat dorsal region.

Accumulation of proanthocyanidins and/or lignin deposition in buff-pigmented soybean seed coats may lead to frequent defective cracking
Defective cracking frequently occurs in buff-pigmented soybean seed coats, where proanthocyanidins accumulate and lignin is deposited, suggesting that proanthocyanidins and/or lignin may change...

Seed coat pigmentation in transgenic soybean expressing the silencing suppressor 2b gene of Cucumber mosaic virus
Soybean expressing the Cucumber mosaic virus 2b gene manifests seed coat pigmentation due to suppression of endogenous RNA silencing but no...

Variation of GmIRCHS (Glycine max inverted-repeat CHS pseudogene) is related to tolerance of low temperature-induced seed coat discoloration in yellow soybean
In yellow soybean, seed coat pigmentation is inhibited by post-transcriptional gene silencing (PTGS) of chalcone synthase (CHS) genes. A CHS cluster named GmIRCHS (Glycine max inverted-repeat CHS pseudogene) is s...

A novel major quantitative trait locus controlling seed development at low temperature in soybean (Glycine max)
Low temperature is among the critical environmental factors that limit soybean production. To elucidate the genetic basis for chilling tolerance and identify useful markers, we conducted quantitative trait loc...

Structural features of GmIRCHS, candidate of the I gene inhibiting seed coat pigmentation in soybean: implications for inducing endogenous RNA silencing of chalcone synthase genes
Most commercial soybean varieties have yellow seeds due to loss of pigmentation in the seed coat. The I gene inhibits pigmentation over the entire seed coat, resulting in a uniform yellow color of mature harveste...

Dose-dependent hypocholesterolemic actions of dietary apple polyphenol in rats fed cholesterol
The dose-dependent hypocholesterolemic and antiatherogenic effects of dietary apple polyphenol (AP) from unripe apple, which contains approximately 85% catechin oligomers (procyanidins), were examined in male ...

Isolation of a subfamily of genes for R2R3-MYB transcription factors showing up-regulated expression under nitrogen nutrient-limited conditions
Plant R2R3-MYB transcription factors are encoded by more than 100 copies of genes. In this study, we attempted to isolate some members of the R2R3-MYB superfamily involved in regulation of nitrogen fixation in le...

New pollen-specific receptor kinases identified in tomato, maize and Arabidopsis: the tomato kinases show overlap** but distinct localization patterns on pollen tubes
We previously characterized LePRK1 and LePRK2, pollen-specific receptor kinases from tomato (Muschietti et al., 1998). Here we identify a similar receptor kinase from maize, ZmPRK1, that is also specifically expr...

Discrimination between Virulent and Attenuated Isolates of Tomato mosaic virus by Restriction Fragment Length Polymorphism
The three missense mutations on the gene for the 130-K protein of Tomato mosaic virus (ToMV) L11A have been thought to be responsible for the attenuation of its virulence. The Eco47I RFLP detecting the missense m...

Characterization of an endopolygalacturonase Gene cppg1 from Phytopathogenic Fungus Chondrostereum purpureum
a phytopathogenic fungus, produces endopolygalacturonase (endoPG) which has been suggested to have a causal role in the silver-leaf symptom of apple trees. In this paper, we detected C. purpureurn-derived endoPG ...

Enhanced expression and differential inducibility of soybean chalcone synthase genes by supplemental UV-B in dark-grown seedlings
By develo** gene-specific RT-PCR and using filters to allow transmission down to 290 nm (UV-B+) or blocking all radiation below 320 nm (UV-B−), the effect of UV-B+ and UV-B− light on expression of each of th...

Complex constitutive nature of Japanese upland rice, Oryza sativa L.
Two rice ecotypes, the so-called lowland and upland populations, which carry different isozyme genotypes mostly at a single locus, are cultivated in Japan. The aim of this study was to examine the origin and t...

The sugar beet mitochondrial gene for the ATPase alpha-subunit: sequence, transcription and rearrangements in cytoplasmic male-sterile plants
We have characterized the mitochondrial atpA (the alpha subunit of F1-ATPase) gene from male-fertile cytoplasm (cv TK81-0) of sugar beet. The gene is 1518-bp long and encodes a polypeptide of 506 amino acids. The...

Genomic organization and sequence analysis of the cytochrome oxidase subunit II gene from normal and male-sterile mitochondria in sugar beet
We have cloned and sequenced the cytochrome oxidase subunit II (coxII) gene from both normal and cytoplasmic male-sterile (CMS) sugar beet. The normal coxII (designated NcoxII) locus was found to be located 1491 ...
