Sorghum Roots Adapt to Thrive in Low-Phosphorus Soils 📝 🧵
https://botany.fyi/4pm1a7
New research reveals how sorghum roots change shape to scavenge for scarce phosphorus, potentially helping breed more resilient crops.
#Botany #PlantScience #InBrief
Scientists have discovered how sorghum roots adapt to low-phosphorus conditions, potentially paving the way for more resilient crops.

2024-09-20 11:30:01

- reply

The study revealed significant adaptations in sorghum root architecture under phosphorus-deficient conditions. Roots grew longer and produced more tips, while becoming thinner to cover more area efficiently. These changes were observed as early as 21 days after germination, with variations among different sorghum varieties. The researchers identified four distinct root system types, suggesting genetic control over these adaptive responses.

Plant Genes Favour Climate Over Soil 📝 🧵
https://botany.fyi/h6t1gw
Climate shapes plant adaptation more than soil type in Arabidopsis thaliana.
#Botany #PlantScience #InBrief
What drives plant adaptation: soil or climate? A new study in Biology Letters by Ellis and colleagues tackles this question using Arabidopsis thaliana from Italy and Sweden. Through a reciprocal transplant experiment, they discovered that climate, not soil type, is the primary force behind plant adaptation.

2024-09-20 03:30:01

- reply

“[T]he relative importance of adaptation to climate and to soil is still incompletely known. We suggest that this is an important gap to fill for understanding and predicting the consequences of environmental change for species distributions, local adaptation and the management of declining species.”

2024-09-20 03:30:01

- reply

They grew Italian and Swedish Arabidopsis thaliana ecotypes at both native sites, using soil from each location. The team transplanted 2,080 seedlings, ensuring a robust sample size. They tracked plant survival, fruit production, and seed count. By comparing plant performance across different site-soil combinations, the researchers could isolate the impacts of climate and soil type on plant fitness and adaptation.

While bees dominated, flies, beetles, butterflies, and birds also played significant roles. Intriguingly, plants often attracted similar pollinators in both native and exotic ranges, particularly at the order level. However, geographic distance negatively correlated with pollinator similarity, suggesting that exotic plants can adapt to new environments by attracting novel pollinators when necessary.

Climate Change Reshapes Oak Pollen, Threatening Bee Nutrition 📝 🧵
https://botany.fyi/cvg74r
Elevated carbon dioxide alters oak pollen nutrients, potentially limiting phosphorus availability for bees in future climates.
#Botany #PlantScience #InBrief
Climate change is reshaping our world in unexpected ways. A recent study by Filipiak and colleagues reveals a hidden impact: rising CO2 levels are altering the nutrient composition of oak pollen.

2024-09-19 11:30:01

- reply

The study uncovered significant changes in oak pollen under elevated CO2. Sulfur, potassium, and iron levels decreased, while phosphorus became more scarce for bees. Two bee species, Osmia bicornis and Apis mellifera, showed different responses to these changes. O. bicornis faced potential phosphorus limitations, especially in high-CO2 conditions. For A. mellifera, both phosphorus and sulfur could become limiting factors.

2024-09-19 11:30:01

- reply

“This area of research is still in its infancy, thus it is important to continue investigating how eCO2 and the resulting changes in the stoichiometry of floral rewards (pollen and nectar) will affect the health and fitness of bees, their interactions with plants, the functioning of bee populations and communities, and ultimately the ecosystem services they provide.”

2024-09-19 11:30:01

- reply

This change could have far-reaching consequences for bees, which rely on pollen for food. Using a sophisticated CO2 enrichment facility, the researchers found that elevated CO2 reduced key nutrients in oak pollen, potentially limiting bee nutrition. These findings highlight the complex challenges facing pollinators in a changing climate.

Suetsugu's team discovered a remarkable twist in A. urashima pollination. Adult Sciophila yokoyamai gnats can enter the flower, deposit eggs, and then successfully escape - a feat unique among the plant's visitors. Their larvae then develop in the decaying blooms, with multiple adults later emerging. This contrasts with other gnat species, which perish in the plant's trap.

New research across Europe reveals significant variation in bacteria living on Arabidopsis thaliana plants. This large-scale study found that drought conditions strongly influence which bacteria colonise plants. The findings show complex relationships between climate, plant genetics, and microbial communities.

2024-09-18 03:30:01

- reply

Researchers found the microbes by collecting A. thaliana samples from 267 locations across Europe between February and May 2018. They sequenced the V3-V4 region of the 16S ribosomal RNA to identify bacterial species present on the plants. DNA extraction and sequencing were also performed to analyse plant genetics.

2024-09-18 03:30:01

- reply

The study identified two distinct bacterial communities on A. thaliana: one prevalent in Northern Europe, the other in Southern Europe. Drought severity emerged as the strongest predictor of which bacterial community a plant harboured. Both plant genetics and drought directly influenced bacterial composition, with 10% of core bacteria affected by drought and 20% by host genetic factors associated with drought tolerance.

By comparing heat-stressed plants to those grown under normal temperatures, they could see the impact of extreme heat on various aspects of plant reproduction.

The researchers identified the damage heatwaves do by exposing Brassica napus (canola) plants to simulated heatwaves of 35°C for 72 hours during flowering. They then conducted hand pollination experiments using both cross- and self-pollen from plants under the same temperature conditions. The team measured key reproductive metrics, including pollen tube growth, pollen production, and seed set.

Some plants have the ability to raise their temperature above that of the surrounding air, an ability called thermogenesis. In a review article published in Nature Plants, David Peris and colleagues examine the origin of thermogenesis and conclude it may have played a crucial role in developing the co-associations between plants and their pollinating insects in the distant past.
