It's a belated present, the PDF of the handout we've been using on stands for Botany One.

A new analysis suggests that long-term, multi-generational response of plants to rising CO₂ are similar to those found in single generation FACE experiments, with consequences for continued global greening and future higher rates of photosynthesis.

For many people, pollen means nose itching and eyes watering - but it is so much more. It is the reason we have food on our plates, and flowers around us. When pollen forms abnormally or degenerates, it is unable to generate new life through the production of a seed. Many factors can affect pollen development, and this is what my research is about.

In plants, respiration is usually inhibited in the light compared to the dark. Measuring respiration in the light is particularly difficult, because photosynthesis and photorespiration are occurring as well. Understanding how light respiration changes with temperature is crucial for predicting how ecosystem-level CO2 exchange will respond to climate change, which can feed back and amplify […]

We owe plants our oxygen, our food, our medicines, our furniture and clothing and the enjoyment of our natural environment. As a consequence, plant scientists have long been engaged in understanding plant growth in relation to their genetic and physiological determinants, and as a result of interactions with environmental drivers such as light, temperature, water […]

We have constructed a new CO₂ microsensor with a tip diameter as small as the thinnest of human hairs. This new microsensor can be positioned in plant tissues in controlled laboratory experiments as well as in the field, and has already revealed some old secrets of submerged aquatic plants.

Guest author Danica Goggin finds wild radish is a problem weed in many agricultural regions. It is also very good at concealing its herbicide resistance strategies from inquisitive researchers. But with the introduction of synthetic auxin-resistant transgenic crops in North America, we need to keep chipping away at this plant’s shield of secrecy.

It's not enough to mimic a female - you have to do it well.

A polysaccharide found in the cell walls of land plants has now been found outside the cell. This chemical, Xyloglucan, could be one of clues as to how plants moved onto land.

We know that flowers entice pollinators with nectar, but how much and what causes a flower to produce as much or as little nectar as it does. In this guest post, Amy Parachnowitsch, Jessamyn Manson and Nina Sletvold introduce their review of the topic, which you can get free from the Annals of Botany.

From August 1 2018, LEGO will begin distribution of the company’s first set of sustainable bricks, “Plants from Plants”, in the form of botanical elements, such as trees, bushes and leaves. Announced on March 1, 2018, these new elements will be made from sugarcane-based polyethylene. This new era of production marks the beginning of the […]

While leafy green vegetables are wilting under the summer heatwave, the drought and heat tolerant leafy vegetable, amaranth, provides a nutritious alternative.
