论文简介：利用无纤维突变体，通过图位克隆了纤维起始基因Li3，该基因是位于染色体D12（GhMML3_D12）上的R2R3-MYB转录因子。借助序列分析和遗传分析，发现li3是一个功能缺失的等位基因，和N3是一对具有加性效应的同源突变体，对纤维(绒或棉)的起始具有加性作用。这些发现为影响棉花纤维起始的遗传因素提供了新的信息。

Mummified baboons likely location fabled land Punt far reach early Egyptian mariners
2021/1/8
The fabled land of ancient Punt was a major trading partner of Egypt's for at least 1,100 years. Punt was an important source of luxury goods, including incense, gold, leopard skins and living baboons...
Sea level rise could make rivers more likely to jump course（图）
Sea level rise make rivers likely jump course
2020/8/21
Sea level rise is poised to shift the way rivers naturally chart their paths to the shoreline. The nature of that change will depend on both the rate of rise and the sediment load carried by the river...

A new study published in the journal Nature indicates that the increase in rainfall forecast by global climate models is likely to hasten the release of carbon dioxide from tropical soils. T...
Dimming Betelgeuse likely isn't cold, just dusty, new study shows（图）
Dimming Betelgeuse just dusty
2020/3/13
Late last year, news broke that the star Betelgeuse was fading significantly, ultimately dropping to around 40% of its usual brightness. The activity fueled popular speculation that the red supergiant...
Ancient molecules from the sea likely burst into the air from ocean waves（图）
Ancient molecules sea air ocean waves carbon cycle organic matter
2019/11/5
When waves break in the ocean, they inject tiny particles into the air, called aerosols, that carry organic molecules more than 5,000 years old. The discovery, published in Science Advances by Steven ...
Collapse of desert bird populations likely due to heat stress from climate change（图）
Collapse bird populations due heat stress climate change
2019/10/17
As temperatures rise, desert birds need more water to cool off. At the same time, deserts are becoming drier, setting some species up for a severe crash, if not extinction, according to a new study pu...

Striped maple trees change mating types females likely to die
2019/10/28
More than 90 percent of flowering plant species combine male and female characteristics in one plant. In the less than 10 percent where female and male flowers exist on separate plants, they typically...
Ancient Sharks Likely More Diverse Than Previously Thought（图）
Ancient Sharks More Diverse Previously Thought
2018/1/31
Sharks have a reputation as ravenous hunters and apex predators, but new analysis of fossil records shows that some of the earliest sharks might have been filter feeders, taking in water through their...

2017/11/23
Conditions in crowded urban settlements in Africa make the effects of climate change worse, pushing temperatures to levels dangerous for children and the elderly in those areas, according to a new stu...
Allowable 'carbon budget' most likely overestimated（图）
carbon budget most likely overestimated
2017/9/1
While most climate scientists, including the Intergovernmental Panel on Climate Change, implicitly define "pre-industrial" to be in the late 1800's, a true non-industrially influenced baseline is prob...

Dark matter cold not fuzzy scientists new simulations
2017/9/1
Scientists have never directly detected dark matter. But over decades, they have proposed a variety of theories about what type of material — from new particles to primordial black holes — could compr...
