The development of new methods for estimating precise forest structure parameters is essential for the quantitative evaluation of forest resources. Conventional use of satellite image data, increasing...
Using residual biomass from forest harvesting to produce energy is viewed increasingly as a means to reduce fossil fuel consumption. However, the impact such practices on soil and future site producti...
Understanding gene expression and regulation requires insights into RNA transcription, processing, modification, and translation. However, the relationship between the epitranscriptome and the proteom...
A fast, reliable and non-destructive method is needed to qualify the extractives content (EC) in heartwood of T. sinensis cores in the breeding program for studying the genetic effect on EC. However, ...
多能干细胞(PSC)因其具有自我更新和多向分化潜能,在体外可以长期培养并能进行基因编辑,其在生命科学与医学领域,以及动物育种应用等领域备受青睐。然而,大家畜,如猪,至今没有获得能够进行生殖嵌合、稳定传代、体外长期培养的多能干细胞系。这也是制约大家畜育种的瓶颈。自第一株小鼠胚胎干细胞报道以来,科学家对猪多能干细胞进了30多年的攻关,虽取得了良好的进展,但仍存在急需解决的科学问题。近日,由中国农业大学...
Available budgets for the inventory of non-commercial woodlands are small. Therefore, there has been increased interest in using distance methods, such as k-tree sampling, which are faster than fixed...
The aim of the present study was to analyse the impacts of different logging intensities after five years from logging including non-logged, low (3.4 felled stems per hectare), medium (5.2 felled stem...
To determine stem rust resistance genes of wheat varieties in Yunnan province, 11 Chinese strains of Puccinia graminis f.sp. tritici with different virulence and 1 artificial mutant strain were used i...
Biologists at Cold Spring Harbor Laboratory (CSHL) have made an important discovery that helps explain how plants regulate the proliferation of their stem cells. The discovery has near-term implicatio...
The study deals with differences in the growth of 2-year mix of poplar clones MAX 4, MAX 5 in the first rotation period at a site with the average moisture regime and at a neighbouring site affected b...
In general, the seminiferous tubule basement membrane (STBM), comprising laminin, collagen IV, perlecan, and entactin, plays an important role in self-renewal and spermatogenesis of spermatogonial ste...
The wheat stem rust pathogen, Puccinia graminis f.sp. tritici, is a significant and devastating disease of wheat crops worldwide. Wheat has many wild relatives in which to source new resistance genes,...
Isolation and culture of spermatogonial stem cells (SSCs) are attractive for production of genetic modified offspring. In the present study, buffalo spermatogonial stem-like cells were isolated, cultu...
We studied effects of repeated nitrogen applications on the stem growth of mature Scots pine at four sites with the yield potential of around 3‒4.5 m3·ha–1·yr–1. Treatments included control (0...
A horse suffering from an undetected hoof bone fracture was diagnosed three weeks after injury. The formation of callus tissue was detected at the fracture site. Standard orthopaedic screw application...
