“…1). However, a large vernalization requirement delays heading in mild winter areas (from 4°C to 10°C) where late heading wheat may be subjected to heat and drought stresses in early summer (Wardlaw 1970, Fischer 1973 or to ear sprouting caused by monsoon rain (Hoshino et al 1989). In contrast, spring-type wheat carrying Vrn-A1 starts spike primordium initiation before winter, and is often subjected to frost injury (Gotoh 1979).…”

Adaptation and ecological differentiation in wheat with special reference to geographical variation of growth habit and Vrn genotype

et al. 2001

Geographical variation of growth habit was studied for 749 landraces from various parts of the world, with special reference to their adaptation and ecogeographical differentiation. The total frequency of spring‐type landraces was 49.9%, and varied between localities. Spring‐type landraces were frequent in two distinct areas where the average January temperature was either below ‐7°C or above 4°C, with winter‐type landraces in areas from ‐7°C to 4°C. These results indicated that geographical variation of growth habit is closely related to the degree of winter coldness. An analysis of the Vrn genotype for 216 spring‐type landraces demonstrated the uneven distribution of four Vrn genes, with Vrn4 being the least frequent. The adaptive Vrn genotype was different between localities. Genotypes carrying Vrn‐A1 and additional Vrn gene(s) were frequent in two distinct areas where the average January temperature was either below ‐7°C or over 10°C, while genotypes with any of three Vrn genes, except Vrn‐A1, adapted to areas with temperatures from 4°C to 10°C. Therefore, it was concluded that the adaptability of wheat landraces differed depending on their growth habit and Vrn genotype, and that ecotypes with different Vrn genotypes were allopatrically distributed as a result of adaptation to different winter temperature. However, the differential distribution of Vrn‐B1, Vrn‐D1 and Vrn4 could not be explained by their adaptability, and might reflect the polyphyletic origin of common wheat.

“…This finding might be related to the fact that some root fragments were able to sprout, but not emerge, when they were buried in the soil and many root fragments decayed under high soil moisture conditions (Figs 4,5). In northern Japan, wheat is harvested during the rainy season (June–July) (Hoshino et al. 1989).…”

This study was conducted to determine the reproductive characteristics of Barbarea vulgaris under different disturbance regimes (mowing and tilling) in two different habitats: a levee and a wheat field. On the levee, 77 of the 114 individuals that had had their floral stalks removed by the first mowing produced new rosettes at the basal part of the stem during the same growing season. The plants that were mowed four times per year had a significantly greater survival rate than the plants that were mowed twice per year. The levee population that was mowed without tillage was largely maintained by vegetative reproduction.These results suggest that mowing the levees promotes the vegetative reproduction of B. vulgaris and helps it to compete with tall-growing plants, thus facilitating its survival as a perennial. In spite of the high sprouting ability of the plant's root fragments, most of the root fragments did not regenerate when buried or when exposed to high soil moisture conditions in tilled wheat fields. The population of B. vulgaris in tilled wheat fields was maintained almost entirely by sexual reproduction. Barbarea vulgaris can survive under two different management regimes by altering its mode of reproduction.

“…To improve pre-harvest sprouting tolerance, we need to identify and understand the regulation of the genes that contribute to increasing seed dormancy. The Zenkoujikomugi (Zen) cultivar has the highest level of seed dormancy among Japanese wheat cultivars, and Chinese Spring (CS) has lower levels of seed dormancy, meaning that CS germinates more readily than Zen (Hoshino et al 1989). To understand the high level of seed dormancy in Zen, quantitative trait loci (QTL) analysis was carried out using recombinant inbred lines (RILs) from a cross between Zen and CS (Mori et al 2005).…”

Diversification of the promoter sequences of wheat Mother of FT and TFL1 on chromosome 3A

et al. 2015

Mother of FT and TFL1 (MFT) participates in the regulation of seed dormancy in wheat. A single-nucleotide polymorphism (SNP) in the promoter of MFT on chromosome 3A (MFT-3A) can explain the difference in the levels of MFT-3A expression, and the difference in seed dormancy, between Chinese Spring (CS) and the CS line with a substituted chromosome 3A from Zenkoujikomugi (Zen) (CS(Zen3A)). Using a cleaved amplified polymorphic sequence (CAPS) marker for this SNP, we analyzed the distribution of the SNP in 694 cultivars, including 117 Japanese cultivars and 551 cultivars from a wheat core collection. The Zen-type SNP predominantly occurs in cultivars used in Japan, where the rainy season overlaps with the wheat harvest season. We also sequenced the *800 bp genomic fragment amplified by the CAPS marker and categorized the sequences into 16 groups, G1-G16. Only G11 has the Zen-type SNP; all the others have the CStype SNP. This indicates that the CS-type allele (T) is ancestral, and during cultivation, nucleotide substitution occurred to give the Zen-type allele (C), which has been adopted to improve pre-harvest sprouting tolerance. Phylogenetic analysis indicates that G11 is derived from G3, which occurs worldwide. Our results suggest that the CAPS marker provides a valuable tool to select the Zen-type MFT-3A allele in wheat Electronic supplementary material The online version of this article (
