(Submitter supplied) Pollen development is central for plant reproduction and is assisted by changes of the transcriptome and the proteome. At the same time, pollen is largely heat sensitive, particularly at early developmental stages. To define the changes during development and the response of different stages to elevated temperatures we investigated the transcriptome and proteome of pollen at tetrad, post-meiotic and mature stage before and after application of elevated temperatures. more...

(Submitter supplied) Male reproductive tissues are more sensitive to heat stress compared to vegetative tissues, however the basis of this phenomenon is poorly understood. Heat stress transcription factors (Hsfs) regulate the transcriptional changes required for protection and recovery from heat stress. HsfA2 has been characterized as co-activator of HsfA1a in tomato and is considered as one of the major Hsfs accumulating in response to elevated temperatures. more...

(Submitter supplied) Alternative splicing caused by exposure of pollen to high temperatures leads to the generation of transcripts with pre-mature termination codon targeted for degradation or mRNAs putatively coding for truncated proteins with altered functions thereby controlling important cellular pathways including transport and localization, heat stress response, gene expression and various biosynthetic processes.

(Submitter supplied) Heat shock proteins (Hsps) are molecular chaperones primarily involved in maintenance of protein homeostasis. Their function has been best characterized in heat stress (HS) response during which Hsps are transcriptionally controlled by heat stress transcription factors (Hsfs). The role of Hsfs and Hsps in HS-response in tomato was initially examined by transcriptome analysis using the Massive Analysis of cDNA Ends (MACE) method. more...

(Submitter supplied) Purpose: Increasing biomass yield and quality of feedstock have been a recent interest in switchgrass research. Despite the economic importance of switchgrass, increasing temperature and water deficit are limiting factors to the cultivation of bioenergy crops in the semi-arid areas. The effect of individual drought or heat stress has been studied separately in switchgrass. However, there is relatively limited or no report on the molecular basis of combined abiotic stress tolerance in switchgrass particularly the combination of drought and heat stress. more...

(Submitter supplied) Pollen development from the microspore involves a series of coordinated cellular events, and the resultant mature pollen is specialized in function that it can quickly germinate and produces a polar-growth pollen tube derived from the vegetative cell to deliver two sperms for fertilization. Understanding the molecular program underlying pollen development and germination still remains a major challenge for plant biology. more...

(Submitter supplied) Plant reproduction is one key biological process very sensitive to heat stress and, as a consequence, enhanced global warming imposes serious threats to sustain food safety worldwide. In this work we have focused on the molecular impact that high temperature conditions impose on gene expression of Arabidopsis pollen germinated in vitro. We have used a high-resolution ribosome profiling technology to provide, for the first time, a comprehensive study of how both the transcriptome and the translatome of germinated pollen respond to the increase in temperature. more...
