Abstract
Previous studies have reported that SEEDSTICK/AGAMOUS-LIKE 11 (AtSTK/AtAGL11), a MADS-box transcription factor, plays important roles in many biological processes in Arabidopsis thaliana. However, the function of BnaAGL11, an AtAGL11 homologous gene from Brassica napus, in leaf development remains unknown. Here, we found that the ectopic expression of any copy of Bna.C09.AGL11, Bna.A03.AGL11, and Bna.A09.AGL11 in A. thaliana led to smaller and curly leaves and promoted leaf senescence. Consistently, the overexpression of Bna.C09.AGL11 in B. napus also caused smaller and curly leaves and accelerated leaf senescence. Furthermore, we demonstrated that Bna.C09.AGL11 controlled leaf morphogenesis by indirectly downregulating the genes of Bna.A01.DWF4 and Bna.C07.PGX3 and promoted leaf senescence by indirectly upregulating the genes of Bna.A04.ABI5, Bna.A05.ABI5, Bna.C04.ABI5-1, and Bna.C01.SEN4 and directly activating the transcription of Bna.C04.ABI5-2 and Bna.C03.SEN4 genes. Our results provide new insights into the underlying regulatory mechanism of BnaAGL11 during leaf development in B. napus.

Abstract
Fruit color is an important economic trait. The color of red walnut cultivars is mainly attributed to anthocyanins. The aim of this study was to explore the differences in the molecular mechanism of leaf and peel color change between red and green walnut. A reference transcriptome of walnut was sequenced and annotated to identify genes related to fruit color at the ripening stage. More than 290 million high-quality reads were assembled into 39,411 genes using a combined assembly strategy. Using Illumina digital gene expression profiling, we identified 4568 differentially expressed genes (DEGs) between red and green walnut leaf and 3038 DEGs between red and green walnut peel at the ripening stage. We also identified some transcription factor families (MYB, bHLH, and WD40) involved in the control of anthocyanin biosynthesis. The trends in the expression levels of several genes encoding anthocyanin biosynthetic enzymes and transcription factors in the leaf and peel of red and green walnut were verified by quantitative real-time PCR. Together, our results identified the genes involved in anthocyanin accumulation in red walnut. These data provide a valuable resource for understanding the coloration of red walnut.

Abstract
Plant growth promotion and inhibition under low- and high-density conditions (referred to as the density effect) has been studied extensively. Here, we show that such density effects were unaffected by the position of wild-type (WT) and gibberellic acid insensitive (gai) strains of Arabidopsis thaliana (Arabidopsis) within pots. Additionally, petanko 1 (pta1) and pta5 were newly discovered alleles of the ROTUNDIFOLIA 3 (ROT3) and DWARF 4 (DWF4) genes that are involved in brassinosteroid biosynthesis. Unlike gai, the semi-dwarf mutants of pta1 and pta5 exhibited normal flowering times and a shortening of rosette leaves at high densities. Moreover, the pta1 and pta5 variants suppressed flowering stem shortening at high densities. pta5, but not pta1 suppressed the reduction in silique number at intermediate densities. SPINDLY (SPY) is a negative regulator of GA signaling, while PHYTOCHROME B (PHYB) is a red-light photoreceptor. High-density growth did not reduce the flowering time of phyB mutants, but did affect that of spy mutants. Neither spy nor phyB suppressed the shortening of rosette leaves at high densities; however, spy suppressed flowering stem shortening. Moreover, spy suppressed the reduction of silique number at high densities, while and phyB promoted the decrease. These data suggest that GA, BR, and light signaling pathways play important roles in the density effect.
