Parasitic plants conspire to keep hosts alive
The plant that encourages kissing at Christmas is in fact a parasite, and new research reveals mistletoe has an unusual feeding strategy. When two mistletoes invade the same tree, they increase photosynthesis to get the nutrients they need, essentially sharing the tree and causing it less harm. (2021-02-23)

Plant responses to climate are lagged
Plant responses to climate drivers such as temperature and precipitation may become visible only years after the actual climate event. This is a key result of new research led by the German Centre of Integrative Biodiversity Research (iDiv), the Martin Luther University Halle-Wittenberg (MLU) and the Helmholtz Centre for Environmental Research (UFZ) published in Global Change Biology. The results indicate that climate drivers may have different effects on the survivorship, growth and reproduction of plant species than suggested by earlier studies. (2021-02-22)

Tweaking corn kernels with CRISPR
Corn has a highly complex genome, making it a challenge to apply genome-editing techniques to it. CSHL Professor David Jackson and postdoctoral fellow Lei Liu used CRISPR to tinker with the corn genome promoter regions and modify stem cell growth. They figured out which sections influence kernel yield, and they hope to make targeted genome-editing in corn more precise and efficient. (2021-02-22)

Time-lapse reveals the hidden dance of roots
New time-lapse videos capture something that's too slow for our eyes to see: the growing tips of plant roots make corkscrew-like motions, waggling and winding in a helical path as they burrow into the soil. By using time-lapse footage, along with a root-like robot to test ideas, researchers have gained new insights into how and why rice root tips twirl as they grow. (2021-02-19)

Perceiving predators: Understanding how plants 'sense' herbivore attack
Plants are known to possess solid immune response mechanisms. One such response is ''sensing'' attack by herbivorous animals. In a new review article, Prof. Arimura from Tokyo University of Science, Japan, discusses ''elicitors''--the molecules that initiate plant defense mechanisms against herbivore attack. He highlights the major types of elicitors and the underlying cellular signaling, and states that this could spur research on organic farming practices that could prevent the use of harmful pesticides.

Membrane building blocks play decisive role in controlling cell growth
Lipids are the building blocks of a cell's envelope - the cell membrane. In addition to their structural function, some lipids also play a regulatory role and decisively influence cell growth. This has been investigated in a new study by scientists at Martin Luther University Halle-Wittenberg (MLU). The impact of the lipids depends on how they are distributed over the plasma membrane. The study was published in 'The Plant Cell'. (2021-02-15)

Drone-based photogrammetry: A reliable and low-cost method for estimating plant biomass
Remote sensing technology has become an increasingly common tool used to measure plant productivity without the need for costly and time-consuming field-based measurements. However, the equipment typically used to remotely measure vegetation has remained prohibitively expensive. Here, researchers used a low-cost drone and camera to create a photomosaic of a tallgrass ecosystem. By comparing their results with measurements collected in the field, they demonstrate that photogrammetry is an accurate and reliable method of estimating biomass. (2021-02-12)

Hidden conflict in the mutually beneficial relationship between legumes and rhizobia
The mutually beneficial relationship between legumes and rhizobia is one of the most well-known and agronomically important examples of symbiosis. A study led by Chapman University's Kenjiro Quides tested the boundaries of this relationship -- and found that it's not always as perfectly harmonious as previously thought. Reported in the journal Evolution, the results suggest a hidden conflict in the symbiotic relationship and provides support for the conclusion that rhizobia have an evolutionary advantage. (2021-02-10)

New factor in the carbon cycle of the Southern Ocean identified
The Southern Ocean is one of the key regions for understanding the climate system. The photosynthesis-performing plankton there contribute significantly to controlling the CO2 concentration in the atmosphere. But which factors favor or limit plankton growth? Researchers have now published a study showing for the first time that, in addition to the micronutrient iron, manganese can play an important role. Among other things, the results have implications for understanding ice ages in the past. (2021-02-09)

There the scientists show that the evolutionary success of insects may be linked to recurrent changes in host plants. (2021-02-09)

Richness of plant species reduces the number of viral infections in meadows
A new study indicates that agricultural activity confuses the mechanisms that regulate the occurrence of plant diseases in nature. A wider variety of virus species was found in meadows close to agricultural fields compared to those located in natural surroundings, with the richness of plant species having no effect on the number of virus species. However, maintaining biodiversity is worthwhile, as plant richness did reduce the number of viral infections in the meadows. (2021-02-08)

New eco-friendly technique protects rice plants against devastating fungal infection
Researchers have developed a new technique to protect rice seeds against fungal infections that can ruin up to half of all rice crops in the world. The biocontrol method, which involves inoculation of flowers with a different fungus that doesn't cause disease and using seeds harvested from the flower to grow crops, is even better at protecting rice plants from diseases than existing fungicide approaches, and could also be used against similar pathogens that affect other staple crops. (2021-02-04)

In symbiosis: Plants control the genetics of microbes
Researchers from the University of Ottawa have discovered that plants may be able to control the genetics of their intimate root symbionts - the organism with which they live in symbiosis - thereby providing a better understanding of their growth. In addition to having a significant impact on all terrestrial ecosystems, their discovery may lead to improved eco-friendly agricultural applications. (2021-02-04)
