LML1, Encoding a Conserved Eukaryotic Release Factor 1 Protein, Regulates Cell Death and Pathogen Resistance by Forming a Conserved Complex with SPL33 in Rice.

Lesion mimic mutants are powerful tools for unveiling the molecular connections between cell death and pathogen resistance. Various proteins responsible for lesion mimics have been identified; however, the mechanisms underlying lesion formation and pathogen resistance are still unknown. Here, we identify a lesion mimic mutant in rice, lesion mimic leaf 1 (lml1).

Effects of vanadate supply on plant growth, Cu accumulation, and antioxidant capacities in Triticum aestivum L.

The effects of normal vanadate (V) supply (40 μM) on copper (Cu) accumulation, plant growth and reduction in Cu toxicity in wheat seedlings (Triticum aestivum L.) were investigated. The results showed Cu accumulation (mg g(-1 )dw) in the applied V treatment was about 10.

Characterization of Cu-tolerant bacteria and definition of their role in promotion of growth, Cu accumulation and reduction of Cu toxicity in Triticum aestivum L.

The effects of Cu-tolerant bacteria strain USTB-O on Cu accumulation, plant growth and reduction of Cu toxicity in wheat seedlings Triticum aestivum L. were investigated. The strain was identified as belonging to Bacillus species and showed a specific tolerance to Cu through binding the Cu ions to the cell walls to reduce their entry into the cells.

Growth Control of Cyanobacteria by Three Submerged Macrophytes.

To illustrate the control of harmful cyanobacterial growth and the removal of nutritients from fresh water, three submerged macrophytes were grown in the raw water of Guishui Lake. Lindernia rotundifolia, Hygrophila stricta, and Cryptocoryne crispatula were grown together in situ to assess their effectiveness in nutrient removal in microcosms. Results revealed the inhibitory effects of these species on cyanobacterial growth.

Effect of organic ligands on accumulation of copper in hyperaccumulator and nonaccumulator Commelina communis.

Better understanding of copper uptake and accumulation regulation in plants is critical to the phytoremediation of copper contaminated soil. This study employed a 30-day pot experiment to assess the relationship between organic ligands and copper accumulation in plants. Hyperaccumulator and nonaccumulator varieties of Commelina communis were used, different organic ligands were applied, and the data of copper accumulation in shoots were collected.
