Knock-down of rice microRNA166 confers drought resistance through changes in leaf morphology (Plant Physiol.)
Plant Science Research Weekly, Research, Research BlogUnder drought conditions, moderate leaf rolling improves yield in rice by reducing water loss and allowing efficient photosynthesis (leaf upright position). In STTM166 transgenic rice plants, miRNA166 is knocked down (STTM means "short tandem target mimic") and the plants constitutively exhibit the…

Arabidopsis calcium-dependent protein kinase AtCPK1 plays a positive role in salt/drought-stress response ($)
Blog, Plant Science Research Weekly, Research, Research BlogCa2+-dependent protein kinases (CPKs) can transfer calcium signals via phosphorylation events, a signaling process important for plant development and response to environmental stresses. With the multitude of CPKs thus far identified and their overlapping roles in both abiotic and biotic stress response,…
How Plants Clear Toxic Proteins
Research, The Plant Cell, The Plant Cell: In a NutshellGil et al. explore ZTL-mediated protein quality control https://doi.org/10.1105/tpc.17.00612
By Kyung-Eun Gil
Background: As sessile organisms, plants have evolved various mechanisms to adapt to environmental changes. Under stressful conditions such as high temperatures, proteins are misfolded…
Dual impact of elevated temperature on plant defense and bacterial virulence in Arabidopsis
Blog, Plant Science Research Weekly, Research, Research BlogHuot et al. describe how elevated temperature (30 °C) enhances Arabidopsis thaliana disease susceptibility to the bacteria Pseudomonas syringae pv. tomato DC3000 (Pst DC3000): this includes an increase of bacterial type III secretion suggesting that increased Pst DC3000 virulence at 30°C is linked…
The tomato DELLA protein PROCERA acts in guard cells to promote stomatal closure
Blog, Plant Science Research Weekly, Research, Research Blog, The Plant CellNuclear accumulation of DELLA proteins induces transcriptional reprogramming and is well known to suppress the gibberellin (GA) pathway. While DELLAs can negatively regulate GA, increased GA levels can also signal DELLA degradation. GA is a growth-regulating hormone that is also involved in inhibiting…
The genome sequence of the wild tomato Solanum pimpinellifolium provides insights into salinity tolerance
Blog, Plant Science Research Weekly, Research, Research BlogWild relatives of domesticated plants, such as tomato, are valuable resource for breeding, but their genomes are often not very well sequenced. Razali et al. provide the first high-quality genome of wild tomato S.pimpinellifolium LA0480, and use Dragon Eukaryotic Analysis Platform to functionally annotate…
