Abstract
Seed is a major storage organ that determines the yield and quality of Camellia oleifera (C. oleifera). Methyl jasmonate (MeJA) is a signaling molecule involved in plant growth and development. However, the role of MeJA in the development of C. oleifera seeds remains a mystery. This study demonstrated that the larger seeds induced by MeJA resulted from more cell numbers and a larger cell area in the outer seed coat and embryo at the cellular level. At the molecular level, MeJA could regulate the expression of factors in the known signaling pathways of seed size control as well as cell proliferation and expansion, resulting in larger seeds. Furthermore, the accumulation of oil and unsaturated fatty acids due to MeJA-inducement was attributed to the increased expression of fatty acid biosynthesis-related genes but reduced expression of fatty acid degradation-related genes. CoMYC2, a key regulator in jasmonate signaling, was considered a potential hub regulator which directly interacted with three hub genes (CoCDKB2-3, CoCYCB2-3, and CoXTH9) related to the seed size and two hub genes (CoACC1 and CoFAD2-3) related to oil accumulation and fatty acid biosynthesis by binding to their promoters. These findings provide an excellent target for the improvement of the yield and quality in C. oleifera.

Abstract
With the development of high-throughput biology techniques and artificial intelligence, it has become increasingly feasible to design and construct artificial biological parts, modules, circuits, and even whole systems. To overcome the limitations of native promoters in controlling gene expression, artificial promoter design aims to synthesize short, inducible, and conditionally controlled promoters to coordinate the expression of multiple genes in diverse plant metabolic and signaling pathways. Synthetic promoters are versatile and can drive gene expression accurately with smart responses; they show potential for enhancing desirable traits in crops, thereby improving crop yield, nutritional quality, and food security. This review first illustrates the importance of synthetic promoters, then introduces promoter architecture and thoroughly summarizes advances in synthetic promoter construction. Restrictions to the development of synthetic promoters and future applications of such promoters in synthetic plant biology and crop improvement are also discussed.

Abstract
Brown leaf spot on tobacco is a serious fungal disease caused by Alternaria alternata. Peroxisomes are organelles playing an important role in the development and infection of plant pathogenic fungi. But, until now, there is no report on the peroxisome dynamics during the conidia germination of A. alternata. To evaluate the roles of peroxisome in the development of the fungus, in the present work, an enhanced green fluorescent protein (eGFP) cassette tagged with peroxisome targeting signal 2 (PTS2) was integrated into A. alternata to label the organelles, and an eGFP cassette carrying a nuclear located signal (NLS) was performed parallelly. The transformants containing the fusions emitted fluorescence in punctate patterns. The fluorescence of eGFP-PTS2 was distributed exactly in the peroxisomes while those of eGFP-NLS were located in the nucleus. Typical AaGB transformants were selected to be investigated for the peroxisome dynamics. The results showed that during spore germination, the number of peroxisomes in the spores decreased gradually, but increased in the germ tubes. In addition, when the transformants were cultured on lipid media, the numbers of peroxisomes increased significantly, and in a larger portion, present in striped shapes. These findings give some clues for understanding the peroxisomal functions in the development of A. alternata.
