上过哈佛的小蜜

应该是上过哈佛大学森林公园(Arnold Arboretum)杂志 (Arnoldia)的小蜜。 说明没有片费的, 我说哈佛大学的杂志, 我送吧。 他们后来给我寄来2本印好的杂志。

1. 这个是四川大学到看熊猫的路上拍的。 是正骨草的花。 我所知的唯一的整个小花变成蜜腺的花。
你看那小蜜的舌头正舔的, 黄色的小碗儿, 就是一个蜜腺。 其它白色的是正常的小花。 这些黄色的蜜腺, 大概10-15%混在花中, 吸引蜜蜂去采蜜, 采蜜的过程中, 把花粉给传了。


而珙桐呢, 是很不同的另外一个植物。
第一个特殊, 是因为属名(Davidia)和科名(Davidiaceae),都是按俺家儿子取名的。(别急, 俺家女儿也有植物名字的, 以后再表)。

而且她们开花的时候, 白色的苞片象雨伞把花保护起来, 远看象满树的白鸽要飞起来, 怪不得英文就叫鸽子树,Dove Tree)。鸽子代表和平, 我站在树下是有和平的感觉, 那些花没有鲜艳的颜色, 但有随着鸽子的飞舞,我能闻到隐隐的幽香。

我 现在找不到她们的E了。 不记得是一定要中蜂的片片(好象是), 还是没有提是关于珙桐这个植物的(好象也是)。 反正我有一个小蜜在这个珙桐花上, 是2011年5月在纽约的植物园拍的。 但是没有给他们。 还有可能就是2010年就问我要片片了, 或是2011年5月前要的。 反正是我有片没有机会给他们, 最后使他们片不对题。

因为文章是关于珙桐的白色Bracket(苞片?)对起雨伞的作用,已经对蜜蜂的吸引, 但是我的片片是中蜂采正骨草。

为了服务文章, 如果有紫外的片片就更好了。 我那次没有带紫外镜头。 也不知道白色苞片会吸收紫外线。 这是黄老师的文章(不是我, 见下面链接)提出的, 我当然是受到杂志才学习到这些的。

3. 好远的地方有一个小蜜。 在采粉!

百度说:
珙桐为落叶乔木。可生长到20-25米高,叶子广卵形,边缘有锯齿。本科植物只有一属两种,两种相似,只是一种叶面有毛,另一种是光面。花奇色美,是1000万年前新生代第三纪留下的孑遗植物,在第四纪冰川时期,大部分地区的珙桐相继灭绝,只有在我国南方的一些地区幸存下来,成为了植物界今天的“活化石”。

EAST LANSING, Mich. — Sheng Yang He, plant biologist at Michigan State University, has been named one of the nation’s most-innovative plant scientists as part of a $75 million new plant science research initiative.

The Howard Hughes Medical Institute and the Gordon and Betty Moore Foundation honored He, from the MSU-Department of Energy Plant Research Laboratory, and 14 other researchers from around the country. The honor will see He’s salary, benefits and research expenses covered for the next five years or longer.

“The magnitude of being named an HHMI-GBMF Investigator hasn’t sunken in, yet,” said He, who is the first MSU professor to earn the award. “It is quite an honor to be selected from a pool of the nation’s best plant scientists, including some of my outstanding colleagues at MSU. It truly reflects the long-term commitment of MSU to make plant science research and education among the nation’s best.”

For nearly 20 years, He has been plotting an original course of research. In the 1990s, he veered away from the area of research most budding plant molecular biologists were pursuing.

“Most of my colleagues were trying to understand how plants defend themselves against disease, the molecular basis of plant resistance,” said He, whose research is funded in part by MSU AgBioResearch. “But I thought the opposite – I wanted to know why plants are susceptible to disease.”

Much of He’s research has focused on the Type III secretion system, a formidable bacterial weapon. Plant scientists have known for years that bacteria secrete disease-promoting proteins, but conventional wisdom held that those proteins affected host cells from the outside. He discovered that some of these proteins act inside plant cells.

“Wouldn’t it be cool if we could find a way to inactivate the pathogen’s Type III secretion system?” He asked.

He, who was selected from nearly 240 applicants, will begin his new appointment in September. He is eligible for renewal for another five-year term.

HHMI and GBMF formed the collaboration because of concern that basic science research has long been underfunded in the United States.

“We think the creation of our joint program underscores the importance of investing in fundamental plant science, and we hope it will encourage others in the United States to make analogous commitments,” said Robert Tjian, HHMI president. “We are as excited as these scientists are to begin putting their best ideas into action.”

Zachary Huang wins first prize

At the MSU’s Global Focus Photography Contest.

I just got the email notification.

Yours,

***************************************************************************************

It is my pleasure to share with you the current Global Focus winners gallery.

As always our judges struggled with singling out winners for first, second, third and honorable mention awards. Our judges include a professional photographer, a staff member from the Eli Broad College of Business, and an International Student. They were impressed by this year’s class of entries and spent considerable time studying and evaluating each photograph on its own merits. We are also proud to have additional winners of the People’s Choice award, selected by online votes from the greater Spartan community.

First place went to a photograph taken in Myanmar by horticulture student Ben Henshaw titled “Mandalay Stroll,” a photojournalistic-like image of a “Mother and Child” in Darfur by anthropology alumna Jennifer Marcy and  an artful image titled “Restaurant by the lake” by entomology professor Zachary Yong Huang.

“People’s Choice” winners were “Rural India” by Pathobiology and Diagnostic Investigation student Madhan Subramanian,  “Carrot Top” by social science alum Glenn Detrick and “Fresh Cherries” by education instructor Leigh Graves Wolf.

These pictures, along with the second, third places and honorable mentions, will be featured in publications and websites managed by International Studies and Programs, MSU Alumni Association and MSU’s international centers and units. Additionally, winners will be placed on display in the lobby and on the walls of MSU’s International Center in the very near future.

Winners will be notified of their prize awards in a separate email message.

Thank you for entering Global Focus.  We look forward to seeing your entries for the 2011 competition.

Researchers discover hormone that could boost plant immune systems

Researchers discover hormone that could boost plant immune systems

Gregg Howe The discovery of a hormone acting like molecular glue could hold a key to bolstering plant immune systems and understanding how plants cope with environmental stress.

The study, featured in the Oct. 6 issue of the journal Nature, reveals how the plant hormone jasmonate binds two proteins together to trigger plant immunity.

“This is the first molecular view of how plants ward off attacks by insects and pathogens,” said MAES biochemistry and molecular biology scientist Gregg Howe, who worked with fellow MAES researcher Sheng Yang He on the study.

Gregg Howe The study, by Howe and He, is a collaboration between the MSU-Department of Energy Plant Research Laboratory and the University of Washington.

“Jasmonate appears to act as molecular glue that sticks two proteins together,” Howe said. “That binding sets off a chain of events leading to the immune response. Determining the structure of the receptor solves a big missing piece of the puzzle.”

Now that researchers understand the structure, they can design new hormone derivatives or other small molecules that can trigger a desired response. Such compounds could help to increase agricultural productivity by aiding plants in resisting bugs and diseases, he added.

The Nature study shows that plants and animals use fundamentally different mechanisms to perceive this type of fatty acid-derived hormone. Humans have prostaglandin hormones, which are structurally similar to jasmonates and also play a role in immune responses. So this study may hold potential benefits for humans as well.

“Plants offer a rich opportunity to understand basic biological processes that are relevant to human health,” Howe said. “The new structural insight into jasmonate perception could have practical applications in medicine, including the design of drugs that stick two proteins together.”

The research was funded by the National Institutes of Health and the U.S. Department of Energy, and supported by the MAES.

CFC party a great success…
