The composite hypothesis under test is that (i) at certain temperature extremes plant growth is depressed by the inactivation of one or a few especially sensitive reactions, and (ii) such growth depression may be prevented by providing the plant with the normal products of the inhibited reactions. Appropriate experimental designs and statistical criteria to test this hypothesis are formulated.

ABSTRACTPlant reproduction is one key biological process very sensitive to heat stress and, as a consequence, enhanced global warming poses serious threats to food security worldwide. In this work we have used a high-resolution ribosome profiling technology to study how heat affects both the transcriptome and the translatome of Arabidopsis thaliana pollen germinated in vitro. Overall, a high correlation between transcriptional and translational responses to high temperature was found, but specific regulations at the translational level were also present. We show that bona fide heat shock genes are induced by high temperature indicating that in vitro germinated pollen is a suitable system to understand the molecular basis of heat responses. Concurrently heat induced significant down-regulation of key membrane transporters required for pollen tube growth, thus uncovering heat-sensitive targets. We also found that a large subset of the heat-repressed transporters is specifically up-regulated, in a coordinated manner, with canonical heat-shock genes in pollen tubes grown in vitro and semi in vivo, based on published transcriptomes from Arabidopsis thaliana. Ribosome footprints were also detected in gene sequences annotated as non-coding, highlighting the potential for novel translatable genes and translational dynamics.

High temperature disrupts the targeting of SRK to the plasma membrane, resulting in breakdown of the stigmatic self-incompatibility response in self-incompatible Arabidopsis transformants.
