本研究对亲本海7124、中棉所36及47个子代纤维发育5,10和15天的转录组数据分析,鉴定到35420个表达基因,构建了纤维伸长相关动态表达调控网络,其中10366个表达基因在子代中产生新等位基因(ENAs);进一步鉴定到7个时空特异调控表达基因簇,差异表达分析筛选到105个候选基因,包含15个新等位基因。CRISPR-cas9系统敲除GhMAH1使纤维显著变短。本研究为解析陆海群体纤维长度变异...
本研究对艾克曼棉、斯蒂芬氏棉和一个陆地棉野生种系进行测序,解析了棉花多倍化及适应性进化过程中广泛存在的基因组结构变异,阐述了棉花生物多样性和棉花驯化的遗传基础;发现编码磷酸肽结合蛋白的基因结构变异可能与棉花纤维长度调控有关,烯酰辅酶Aδ异构酶3和RAP2-7可通过调节植物激素提高棉花非生物胁迫耐受性。研究结果揭示了棉花多倍化过程中的适应性进化机制,为棉花抗性和纤维品质遗传改良提供了宝贵的遗传材料。
本研究发现MYB5_A12在陆地棉(SG747)纤维起始及伸长早期的表达水平显著低于海岛棉(GZ75);通过QTL共定位分析发现,海岛棉GbMYB5_A12的等位基因型与纤维长度(FL)、纤维强度(FS)和衣分(LP)等性状显著正相关,其启动子区的顺式作用元件TFmatrixID_0063 (GATGTTGT)的自然变异可能导致海陆等位基因差异表达;通过酵母单杂及双荧光素酶报告基因实验验证了RAV...
Short basal internodes are important for lodging resistance of rice (Oryza sativa L.). Several canopy indices affect the elongation of basal internodes, but uncertainty as to the key factors determini...
Plant root growth is controlled by auxin (IAA) and ethylene. The appropriate IAA concentration is regulated by many events, such as IAA biosynthesis, conjugation, and degradation. The levels of ethyle...
Mammalian target of rapamycin complex 1 (mTORC1) is a central regulator of cell growth and metabolism and is sufficient to induce specific metabolic processes, including de novo lipid biosynthesis. El...
Aroma and cooked kernel elongation are the most important quality traits of aromatic rice, which differentiate the highly valued aromatic rice from the other rice types. Previous studies on genetic an...
We investigated the usefulness of the promoter of a gene for tobacco elongation factor 1α protein (EF1 α) for transgene expression in the chrysanthemum (Chrysanthemum morifolium Ramat.). The EF1 α pro...
Rhizome expansion system of bamboo (Phyllostachys pubescens) was investigated in a northwest part of Gifu Prefecture. Growth pattern was observed by measuring annual rhizome elongation in 10 m×10 m st...
Control of internode elongation is important to avoid seed yield reduction caused by the lodging and competition for photosynthate between stem and pods after flowering in soybean (Glycine max Merr.)....
Using an unbonded strain gauge transducer (1kg) and a null balancing recorder, the vertical elongation force (Ef) or lifting force of 1-, 3- and 5-cm tall soybean seedlings (cv: Akisengoku and Fukuyu...
The emergence and elongation of the tiller buds of rice plants are greatly affected by the environmental temperature, especially by the temperature around the culm-bases where the tillers differentiat...
In order to obtain the fundamental information on chemical control of plant structure in soybean ( Glycine max Merr. cv. Fukuyutaka), the effects of growth regulators on the internode elongation were ...
In order to obtain fundamental information on the chemical control of plant structure in soybean (Glycine Max Merr. cv. Fukuyutaka), the effects of gibberellic acid (GA3) on the internode elongation w...
The main aim of this paper is to present how the leaf sheath concerns internode elongation in rice, using the japonica cultivar Sasanishiki. Leaf sheaths were removed at the begining of the rapid elon...
