2,4-D attenuates salinity-induced toxicity by mediating anatomical changes, antioxidant capacity and cation transporters in the roots of rice cultivars
In this study, the effects of recommended dose of 2,4-dichlorophenoxyacetic acid (2,4-D) on growth, oxidative damage, antioxidant defense, regulation of cation transporter genes and anatomical changes in the roots of rice cultivars XS 134 (salt resistant) and ZJ 88 (salt sensitive) were investigated under different levels of saline stress.

Arabidopsis gene expression in hypobaria
Researchers show how plants use new patterns of gene expression to physiologically adapt to wide changes in atmospheric pressure over time, and provide an insight into how the effects of hypobaria can be mitigated or utilized for plant growth in support of exploration.

Effect of asymmetric warming on plant invasion
Researchers tested the impacts of unequal night-and-day warming on seed germination and seedling growth of invasive and native plants. Most warming treatments facilitated seed germination in natives but not in invasives.

Ectopic expression of Triticum aestivum SERK genes (TaSERKs) control plant growth and development in Arabidopsis
The inhibitory action of auxin and brassinosteroid in all the TaSERK transgenic lines indicates their role in regulating root development. The results obtained imply redundant functions of TaSERKs in maintaining plant growth and development.

Change (your seed size) fast and multiply
Scientists found that faster rates of seed size change were associated with faster rates of speciation, probably by fostering the appearance of reproductive barriers between lineages.

Arabidopsis R1R2R3-Myb proteins are essential for inhibiting cell division in response to DNA damage
Inhibition of cell division is an active response to DNA damage that enables cells to maintain genome integrity. However, how DNA damage arrests the plant cell cycle is largely unknown.
