Ethylene biosynthesis and action in tomato: a model for climacteric fruit ripening.
TLDR
A number of ethylene-regulated ripening-related genes are discussed, including those involved in ethylene synthesis, fruit texture, and aroma volatile production, as well as experiments designed to elucidate the ethylene signalling pathway from receptor through intermediate components similar to those found in Arabidopsis.
Recent advances in ethylene research.
TLDR
This review integrates knowledge from the model plant Arabidopsis and other plant species and focuses on key aspects of recent research on regulatory networks controlling ethylene synthesis and its role in flower development and fruit ripening.
A tomato HD-Zip homeobox protein, LeHB-1, plays an important role in floral organogenesis and ripening
TLDR
The findings suggest that LeHB-1 is not only involved in the control of ripening but also plays a critical role in floral organogenesis.
Differential expression of the 1-aminocyclopropane-1-carboxylate oxidase gene family of tomato.
The tomato ACC oxidase gene family is comprised of three members designated AC01, AC02 and AC03. These are highly homologous throughout the protein coding regions but do show a degree of sequence
Antisense gene that inhibits synthesis of the hormone ethylene in transgenic plants
TLDR
It is shown that antisense RNA, which has previously been used only to reduce the expression of genes of known function when applied to pTOM13, reduces ethylene synthesis in a gene dosage-dependent manner.
hydra Mutants of Arabidopsis Are Defective in Sterol Profiles and Auxin and Ethylene Signaling Article, publication date, and citation information can be found at
TLDR
A model in which correct sterol profiles are required for regulated auxin and ethylene signaling through effects on membrane function is proposed, which shows that the hydra mutants of Arabidopsis exhibit enhanced responses to auxin.
Identification and genetic analysis of normal and mutant phytoene synthase genes of tomato by sequencing, complementation and co-suppression
TLDR
In some mutant plants transformed with the TOM5 cDNA construct, inhibition of carotenoid production in immature green fruit, leaves and flowers was observed, indicating that different insertion events with the same gene construct can lead to overexpression or co-suppression in transgenic plants.
Ethylene and developmental signals regulate expression of lipoxygenase genes during tomato fruit ripening
TLDR
The results indicate that individual LOX isoforms are differentially regulated and may have distinct functions during tomato fruit ripening and that a combination of ethylene and developmental factors influence their expression.
Yeast targets for mRNA methylation
TLDR
It is demonstrated that in S. cerevisiae, substantial levels of internal adenosine methylation are present in the GpA context in mRNA from sporulating cells, which is consistent with the preferred methylation consensus of higher eukaryotes.
