Growth And Yield

Chloroplasts are intracellular semiautonomous organelles central to photosynthesis and are essential for plant growth and yield. The significance of the function of chloroplast-related genes in response to climate change has not been well studied in crops. In the present study, the initial focus was on genes that were predicted to be located in the chloroplast genome in rice, a model crop plant, with genes either preferentially expressed in the leaf or ubiquitously expressed in all organs. The characteristics were analyzed by Gene Ontology (GO) enrichment and MapMan functional classification tools. It was then identified that 110 GO terms (45 for leaf expression and 65 for ubiquitous expression) and 1,695 genes mapped to MapMan overviews were strongly associated with chloroplasts. In particular, the MapMan cellular response overview revealed a close association between heat stress response and chloroplast-related genes in rice. Moreover, features of these genes in response to abiotic stress were analyzed using a large-scale publicly available transcript dataset. Consequently, the expression of 215 genes was found to be upregulated in response to high temperature stress. Conversely, genes that responded to other stresses were extremely limited. In other words, chloroplast-related genes were found to affect abiotic stress response mainly through high temperature response, with little effect on response to drought and salinity stress. These results suggest that genes involved in diurnal rhythm in the leaves participate in the reaction to recognize temperature changes in the environment. Furthermore, the predicted protein–protein interaction network analysis associated with high temperature stress is expected to provide a very important basis for the study of molecular mechanisms by which chloroplasts will respond to future climate changes.

ABSTRACTCalcineurin is a conserved calcium/calmodulin-dependent serine/threonine-specific protein phosphatase that acts in cell stress responses. Calcineurin is essential for growth at 37°C and for virulence of the human fungal pathogenCryptococcus neoformans, but its substrates remain unknown. The C2 domain-containing, phospholipid-binding protein Cts1 was previously identified as a multicopy suppressor of a calcineurin mutation inC. neoformans. Here we further characterize the function of Cts1 and the links between Cts1 and calcineurin. GFP-Cts1 localizes to cytoplasmic puncta and colocalizes with the endosomal marker FM4-64. Thects1Δ mutant shows a distinct FM4-64 staining pattern, suggesting involvement of Cts1 in endocytic trafficking. In large budded cells, GFP-Cts1 localizes transiently at the mother bud neck, as a single ring that undergoes contraction. mCherry-Cts1 colocalizes with the GFP-tagged calcineurin catalytic subunit Cna1 at sites of mRNA processing at 37°C, suggesting that Cts1 and calcineurin function coordinately during thermal stress. GFP-Cts1 exhibits slower electrophoretic mobility for cells grown at 37°C than for cells grown at 24°C, and the shift to a higher molecular weight is more pronounced in the presence of the calcineurin inhibitor FK506.In vitrotreatment with calf intestinal alkaline phosphatase (CIP) restores faster electrophoretic mobility to GFP-Cts1, suggesting that Cts1 is phosphorylated at 37°C and may be dephosphorylated in a calcineurin-dependent manner. mCherry-Cts1 also coimmunoprecipitates with GFP-Cna1, with greater complex formation at 37°C than at 24°C. Taken together, these findings support potential roles for Cts1 in endocytic trafficking, mRNA processing, and cytokinesis and suggest that Cts1 is a substrate of calcineurin during high-temperature stress responses.
