It is generally accepted that jasmonate-ZIM domain(JAZ)repressors act to mediate jasmonate(JA)signaling via cORONATINE-INSENSITIVE1(cOI1)-mediated ***,we report a cryptic signaling cascade where a JAZ repressor,FvJAZ12,mediates multiple signaling inputs via phosphorylation-modulated subcellular translocation rather than the cOI1-mediated degradation mechanism in strawberry(Fragaria vesca).FvJAZ12 acts to regulate flavor metabolism and defense response,and was found to be the target of Fv MPk6,a mitogen-activated protein kinase that is capable of responding to multiple signal ***6 phosphorylates FvJAZ12 at the amino acid residues S179 and T183 adjacent to the PY residues,thereby attenuating its nuclear accumulation and relieving its repression for FvMYc2,which acts to control the expression of lipoxygenase 3(FvLOX3),an important gene involved in JA biosynthesis and a diverse array of cellular *** data reveal a previously unreported mechanism for JA signaling and decipher a signaling cascade that links multiple signaling inputs with fruit trait development.

The cuticle is a crucial barrier on the aerial surfaces of land plants, in many plants, including Arabidopsis, the sepals and petals form distinctive nanoridges in their cuticles. However, little is known about how the formation and maintenance of these nanostructures is coordinated with the growth and development of the underlying cells. Here we report the characterization of the Arabidopsis cutin synthase 2 （cus2） mutant, which causes a great reduction in cuticular ridges on the mature sepal epidermis, but only a moderate effect on petal cone cell ridges. Using scanning electron microscopy and confocal live imaging combined with quantification of cellular growth, we find that cuticular ridge formation progresses down the sepal from tip to base as the sepal grows, pcUS2：：GFP-GUS reporter expression coincides with cutic- ular ridge formation, descending the sepal from tip to base. Ridge formation also coincides with the reduction in growth rate and termination of cell division of the underlying epidermal cells. Surprisingly, cuticular ridges at first form normally in the cus2 mutant, but are lost progressively at later stages of sepal development, indicating that cUS2 is crucial for the maintenance of cuticular ridges after they are formed~ Our results reveal the dynamics of both ridge formation and maintenance as the sepal grows.

Tomato(Solanum lycopersicum)is the second most important vegetable crop globally,after potato,with about 100 million tons fresh fruit being grown on 3.7 million hectares(FAO 2021),and is of great importance in the human diet due to the large amount of fruit *** fruit are eaten both fresh and,equally importantly,as a processed product in puree,soups and canned *** provide an important dietary source of vitamins and minerals,such as k,Fe and ca,and are known for the large number of health promoting secondary metabolites,including the carotenoid and flavonoid pigments that give the fruit a spectrum of yellow,red and orange colours.

Artemisia annua, commonly known as sweet wormwood or Qinghao, is a shrub native to china and has long been used for medicinal purposes. A. annua is now cultivated globally as the only natural source of a potent anti-malarial compound, artemisinin. Here, we report a high-quality draft assembly of the 1.74-gigabase genome of A. annua, which is highly heterozygous, rich in repetitive sequences, and contains 63 226 protein-coding genes, one of the largest numbers among the sequenced plant species. We found that, as one of a few sequenced genomes in the Asteraceae, the A. annua genome contains a large number of genes specific to this large angiosperm clade. Notably, the expansion and functional diversification of genes encoding enzymes involved in terpene biosynthesis are consistent with the evolution of the artemi- sinin biosynthetic pathway. We further revealed by transcriptome profiling that A. annua has evolved the sophisticated transcriptional regulatory networks underlying artemisinin biosynthesis. Based on compre- hensive genomic and transcriptomic analyses we generated transgenic A. annua lines producing high levels of artemisinin, which are now ready for large-scale production and thereby will help meet the chal- lenge of increasing global demand of artemisinin.
