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.

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.
