HSP70 proteins are well known as molecular chaperones involved in protein folding and quality control. Whether they also function in gene transcription on chromatin, and if so, how they are regulated, remains elusive. Here we report that HSP70 can also regulate gene transcription through its association with chromatin, distinct from its “classic” function as a molecular chaperone.

When relatives mate, their inbred offspring often suffer a reduction in fitness-related traits known as “inbreeding depression.” Environmental stresses such as starvation and competition can exacerbate these fitness costs of inbreeding. However, caring parents could mitigate the fitness costs of inbreeding by neutralizing the effects of these environmental stresses.

Terpenoids are the largest group of plant-specialized metabolites and include many valuable bioactive compounds, such as the blockbuster anticancer drugs vincristine and vinblastine, that are monoterpenoid indole alkaloids from the medicinal plant Catharanthus roseus (Madagascar periwinkle).

Histone phosphorylation and chromatin reorganization are emerging as critical factors in eukaryotic responses to environmental stimuli. Phosphorylation of histone H3 at Thr 3 is evolutionarily conserved but its role(s) in interphase cells has remained unexplored. In Arabidopsis, we found that H3T3ph increases in pericentromeric regions upon drought-like treatments and it might be required for maintaining proper heterochromatin/chromosome structure.

Specific homologs of the plant Mildew Locus O (MLO) gene family act as susceptibility factors towards the powdery mildew (PM) fungal disease, causing significant economic losses in agricultural settings. Thus, in order to obtain PM resistant phenotypes, a general breeding strategy has been proposed, based on the selective inactivation of MLO susceptibility genes across cultivated species. In this study, PCR-based methodologies were used in order to isolate MLO genes from cultivated solanaceous crops that are hosts for PM fungi, namely eggplant,

Nonphosphorus lipids produced by heterotrophic bacteria have been measured in marine ecosystems without an understanding of their origins or role. This work shows SAR11 chemoheterotrophic bacteria synthesize multiple nonphosphorus lipids in response to phosphate depletion. Because this process results in a reduced cellular P:

Sheath blight, caused by the pathogenic fungus Rhizoctonia solani Kühn, is one of the most devastating diseases in rice. Breeders have always faced challenges in acquiring reliable and absolute resistance to this disease in existing rice germplasm. In this context, 40 rice germplasm including eight wild, four landraces, twenty- six cultivated and two advanced breeding lines were screened utilizing the colonized bits of typha.

Leucine-rich repeat extensins (LRXs) are extracellular proteins with an N-terminal leucine-rich repeat (LRR) and a C-terminal extensin domain. Previous studies on Arabidopsis thaliana root hairs reveal that LRX proteins are important for cell wall development. However, their importance of LRX proteins in non-root hair cells and the effect of mutations in LRX genes remain unclear.

Our objective was to investigate the physiological basis of genetic progress in grain yield in CIMMYT spring wheat (Triticum aestivum L.) cultivars developed from 1966 to 2009 in irrigated, high-potential conditions. Field experiments were conducted during three growing seasons in northwest Mexico (2008–2009, 2009–2010, and 2010–2011) examining 12 historic CIMMYT semidwarf spring wheat cultivars released from 1966 to 2009. The linear rate of genetic gain in grain yield was 30 kg ha−1 yr−1 (0.59% yr−1; R2 = 0.58, P = 0.01).

Many viruses, including those of global concern, are dependent on internalization for their entry. We found that ribonuclease kappa (RNASEK) is required for infection of every virus we tested that enters cells through an acid-dependent pathway, including dengue, West Nile, Sindbis, Rift Valley Fever, and influenza viruses. Mechanistically, we found that RNASEK has no effect on virus binding to cells but, rather, is required for their uptake.
