The disclosure relates to polynucleotides comprising an endocarp-specific promoter sequence from the peach peroxidase (POX) gene operably linked to a heterologous nucleotide sequence encoding a product of interest. The polynucleotides can be used to specifically alter endosperm gene expression in fruit. In a transgenic cell, the polynucleotides may block formation of phenylpropanoid pathway lignin-pathway precursors, formation of lignin monomers, and/or polymerization of lignin monomers.

Endocarp-specific promoter and uses thereof

A method of increasing east one growth characteristic of a plant comprising growing astrain in or on a medium in a container, where a headspace of saidin said container is in fluid communication with a headspace of said plant, where saidproduces at least one volatile organic compound (VOC), where said at least one VOC produced by saidcauses the plant to have an increase in at least one growth characteristic when compared to the growth characteristic of a plant which has not been exposed to the VOC, and where saidcomprises an ITS1/2 consensus amplicon of SEQ ID NO: 5 and an ITS3/4 consensus amplicon of SEQ ID NO: 6.

Fungal volatile organic compound enhances plant s growth characteristics

Disclosed is a novel gene that controls the branching angle of a tree wherein either silencing or overexpressing PpeTAC1 controls the architecture of transformed to the tree.

To produce early flowering genotypes, plum () was transformed with the poplar () Flowering Locus T1 (PtFT1) gene. Ectopic expression of 35S::PtFT1 Induced early flowering in vitro from transgenic plantlets within two months of transformation. When the transgenic plum plants were rooted and transferred to soil and grown in posts in the growth chamber, a number of additional lines flowered. Normal flowering and fruiting were observed in the greenhouse within one year of transformation. While dormancy was not necessary for growth or fruiting, FT plums were still winter hardy and floral bud set and flowering responded normally to changes in temperature. By manipulating a single gene, temperate tree crops can be effectively engineered for cultivation in new growing areas and for entirely new modes of agricultural production that are continuous, sustainable, and adaptable to climate change.
