This study was designed to estimate the variation in non-volatile carbon (C) content in different above- and belowground tree parts (stem, living branches, dead branches, stumps, coarse roots and smal...
Gene copy number variation is frequent in plant genomes of various species, but the impact of such gene dosage variation on morphological traits is poorly understood. We used a large population of Pop...
The spatial distribution of the population is uneven?for various reasons, such as urban-rural differences and geographical conditions differences. As the basic element of the natural structure of the ...
Afforestation plays an important role in controlling soil erosion and nutrient loss on the Loess Plateau in China. However, previous studies on soil nutrient changes have mainly focused on the effects...
For their quality evaluation, it is essential to determine both bamboo shoot nutrition and palatability, which will have a decisive effect on their economic value and market potential. However, differ...
水稻是全球最为重要的粮食作物之一,在其漫长的驯化过程中形成了形态各异的水稻栽培亚型,包括粳稻、籼稻、Aro和Aus等。在水稻栽培种植历史过程中,有些水稻逐渐恢复部分野生稻表型特征,最终演化成严重威胁全球水稻产量的杂草稻,这种现象称之为“去驯化”。通过基因组进化研究发现,大量驯化位点的变异在去驯化过程中并不能得到恢复,这就暗示着可能存在别的遗传机制来调控杂草稻在去驯化过程中恢复野生稻表型。DNA甲基...
Vegetation indices (VIs) are mainly associated with plant yield, and yield-related physiological traits can assist in breeding selection. Tree breeding programs require a rapid assessment of a large n...
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...
2021年5月26日,南京农业大学作物遗传与种质创新国家重点实验室小麦遗传育种创新团队在分子植物杂志(Molecular Plant)发表了“A natural variation of an SVP MADS-box transcription factor in Triticum petropavlovskyi leads to its ectopic expression and contr...
A thorough understanding of carbon storage patterns in forest ecosystems is crucial for forest management to slow the rate of climate change. Here, we explored fine-scale biomass spatial patterns in a...
Grain protein content (GPC) affects rice nutrition quality. Here, we identify two stable quantitative trait loci (QTLs), qGPC-1 and qGPC-10, controlling GPC in a mapping population derived from indica...
The aim of this study was to determine the levels of ascorbic acid and total nitrates in the fresh aerial parts of different varieties of basil (Ocimum basilicum L.) in different growing seasons. The...
The experiment was aimed at confirming that silages made of two very similar hybrids could have different in vivo digestibility, primarily amylase-treated neutral detergent fibre digestibility (aNDFD...
This study was designed to characterize the DNA polymorphisms of the melanocortin-1 receptor (MC1R) gene in indigenous Saudi Arabian sheep breeds exhibiting different color coats, along with individua...
The study of young poplar tree characteristics like initial diameter and height as well as mineral fertilization that promotes the rapid growth of trees for biomass production was the aim of this rese...
