Dwindling phosphate reserves and the high costs of P fertilisers drive the need to develop more P-efficient crops through enhancing P uptake. We expected that , a cluster-root-forming species, would be better at P acquisition than other species. , however, developed a root system with better P uptake traits and had a higher P uptake efficiency. Therefore, other root traits besides cluster roots are important for enhancing P uptake in plants.
Potato is a high nitrogen-responsive crop, hence improving nitrogen use efficiency (NUE) of plant is important to reduce production cost and minimize environmental loss. Potato is a less studied crop especially at plant level with enhanced NUE. This review highlights translation of advanced NUE research from other plants like , rice, wheat and maize applying integrated genomics, physiology and breeding approaches.
Does an optimal level of salt concentration exist for plants?
Bacterial pathogens secret effectors to modulate plant immunity, enabling unlimited pathogen growth inside host, and causing disease. pv. executes XopR effector to suppress immune responses in rice for its growth and subsequent blight disease. This finding provides insights into understanding the key weapon used by the pathogen, and will help to identify the novel targets for disease management.

Cascades by which signalling molecules participate in plant responses to changes in environmental conditions are still under intensive study. Our aim was to explain the role of NO, H2O2 and H2S in adaptation of cucumber seedlings to both salt and low temperature stress. Results show that signalling molecules are important for understanding the mechanisms of modification of the activity of the plasma membrane proton pump, which is a key enzyme in abiotic stress conditions.

Root properties impact strongly on plant performance, but high-throughput methods for non-invasive and quantitative root trait assessment are rarely available. We developed and tested a root phenotyping concept, which involves NIR imaging of roots grown along surfaces of transparent culture vessels using visible light blocking long pass filters. We reveal the viability of the concept and its suitability for simultaneous root and shoot phenotyping.
Will Chelates Improve Plant Growth? - Garden Myths
Many environmental stresses are periodic and predictable. Plants have adapted to these by temporally organising their stress responses to maximise efficiency and efficacy. We review current evidence for temporal regulation of responses to the environment and environmental impacts on the plant circadian clock. Better understanding of the reciprocal interactions between the plant circadian clock and environmental stresses may aid in identifying mechanisms to improve plant growth and increase food security.

We tested whether the removal of nematodes by means of nematicide application changed plant performance or influenced plant competition. The study involved the two common plant species Artemisia maritima and Festuca rubra growing in intact sods collected from a temperate salt marsh. Half of the sods were treated with fenamiphos ('Nemacure', Payer AG), a nematicide controlling both endo- and ectoparasitic nematodes. In untreated soil, the number of both total and plant-parasitic nematodes (7000 vs. 1000 per 100g fresh soil, respectively) was comparable to accounts from other salt marsh systems. After four months, the nematicide had reduced nematode numbers by 90%, but no influence on plant biomass or competitive ability of the two plant species was observed. As we did not follow the trajectory of nematicide effects on the nematodes, the exposure period of the test plants to low numbers of nematodes cannot be assessed. Experimental periods may need to be extended in order to evaluate long-term effects of reduced nematode numbers on plant productivity and plant competition in temperate salt marshes. On the basis of this pilot experiment we regard plant-parasitic nematodes to have a minor direct impact on productivity and interspecific relationship between the salt-marsh plant species investigated.
