Seed priming is a physiological seed enhancement method. Hydro- or osmotic can advance germination under adequate moisture conditions. During direct seeding on well-drained paddy and upland fields, rice seeds occasionally encounter low soil Under these conditions, need to undergo rapid secure emergence through improved water absorption capacity bioactive. This study aims clarify the effects of hydropriming seedling vigor in different The employed three hydration conditions such as priming,...
Matsutake mushrooms are among the best-known edible wild mushroom taxa worldwide. The representative Tricholoma matsutake is from East Asia and northern central regions of Europe. Here, we report existence T. under fir trees in Eastern Europe (i.e., Ukraine), as confirmed by phylogenetic analysis nine loci on nuclear mitochondrial genomes. All specimens Japan, Bhutan, China, North Korea, South Sweden, Finland, Ukraine formed a clade according to phylogeny internal transcribed spacer region....
A full-length cDNA clone encoding granule-bound starch synthase I (GBSSI = Waxy gene) from grain amaranth (Amaranthus cruentus L.) perisperm was isolated and characterized. Segregation of amylose content in F2 population suggested that the is controlled by a single gene, (GBSSI). this gene 2076 bp length contains an open reading frame 1821 corresponding to polypeptide 606 amino acids residues, including transit peptide 77 acids. Comparison genomic sequences (3492 bp) GBSSI has 12 introns,...
A rapid and reliable PCR-restriction fragment length polymorphism (RFLP) marker was developed to identify the Amaranthus cruentus species by comparing sequences of starch branching enzyme (SBE) locus among three cultivated grain amaranths. We determined partial SBE genomic sequence in 72 accessions collected from diverse locations around world direct analysis. Then, we aligned gene searched for restriction cleavage sites specific each use PCR-RFLP The result indicated that MseI would...
The effects of storage temperature (5°C, 10°C, and 15°C) on the appearance, weight, ascorbic acid content 3 asparagus cultivars—‘UC157’, ‘Gijnlim’, ‘Purple Passion’—cultivated as green in open fields were investigated over a 4-day period. In addition, we respiration rate (CO2 production rate), which is closely related to qualitative deterioration fresh produce. Among cultivars, ‘Gijnlim’ had loosest spear-head highest immediately after harvest. extent opening during period varied among was...
The amounts of taste components, including those for pungency, in chili pepper fruit change depending on environmental factors. Our previous study revealed that the amount capsaicinoid was significantly increased fruits were cultivated under a drought stress condition. Therefore, present experiment conducted to determine effect pungency and expression levels biosynthesis genes peppers. Japanese cultivars 'Shishito' 'Sapporo' selected greenhouse condition or an excess water supply used...
Capsaicinoids are compounds that generate the characteristic pungent taste of chili peppers, presence or absence which determines utilization peppers as spices vegetables. Loss pungency is a qualitative trait resulting from dysfunction in any four capsaicinoid biosynthesis genes (Pun1, pAMT, CaKR1, and CaMYB31). However, lack sweet cannot be explained by known mutation alleles these genes. Herein, we report novel dysfunctional allele Pun1, encodes acyltransferase 3 (capsaicin synthase),...
Rice bran application is practically used by Japanese organic rice farmers as a common measure in controlling Monochoria vaginalis, known weed production. To elucidate the inhibitory mechanisms of on M. vaginalis germination, we focused volatile fatty acids (VFAs) and aromatic carboxylic (ACAs) produced through decomposition soil, which can possibly suppress germination. Both solo solutions 1 mM VFAs (propionic or isobutyric acid) 0.2 ACAs (3-phenylpropionic 4-phenylbutyric exhibited...
Field experiments were conducted to analyze the relationship between settled soil volume in water (SSVW) and growth of Monochoria vaginalis (Burm. f.) Kunth under organic farming conditions. SSVW corresponds mud per dry matter weight. Soil was sampled from superficial layer topsoil (<10 mm), which a finer texture than rest topsoil. Without application rice bran, there negative correlation number individuals M. vaginalis. This finding suggests that is useful as physical indicator for...
A gene encoding squalene synthase from grain amaranth was cloned and characterized. The full-length cDNA 1805-bp long contained a 1248-bp open reading frame protein of 416 amino acids with molecular mass 47.6 kDa. Southern blot analysis revealed that the A. cruentus genome single copy gene. Comparison genomic sequences indicated SQS had 12 introns 13 exons. All exons contributed to coding sequence. predicted acid sequence shared high homology those SQSs several other plants. It five...
打込み式代かき同時土中点播機を用いた安定的湛水直播栽培法の確立のため, 異なる苗立ち密度(40, 80および160本m-2)における耐倒伏性を散播水稲と比較して点播水稲の耐倒伏性に関する特性解明を行った. その結果, 点播水稲は散播水稲に比較して稈が長くなるために稈基部にかかる力が大きくなるが, 有効茎歩合が高いために耐倒伏性に関連した稈の形質が優れること, 押し倒し抵抗値が顕著に大きいことにより稲株の耐倒伏性が強化され, 倒伏を生じにくいことが明らかとなった. また, このような播種様式間差は苗立ち密度の高い条件で顕著となった. 押し倒し抵抗値の変動要因を検討した結果, 散播水稲において1株穂数が10本以下の株は押し倒し抵抗値の変動が大きく, 1株穂数の減少により抵抗値が顕著に低下するのに対し, 1株穂数が10本以上の株は押し倒し抵抗が安定して高かった. このことから, 散播水稲では苗立ち密度40本m-2以上の条件では1株穂数が10本以下となるために, 苗立ち密度の変動により1株穂数が変動するのに対し, 点播水稲は標準的な播種条件(条間30cm,...
