“…Suc-induced anthocyanin accumulation was significantly reduced in the single mutants arr1, arr10, and arr12, the double mutants arr1/10, arr1/12, and arr10/12, and the triple mutant arr1/10/12 treated with CK, indicating that ARR1, 10 and 12 act as positive regulators of CK signaling ( Fig. 2C; Das et al, 2012). Furthermore, it turns out that CK enhances Suc induction of anthocyanin accumulation by affecting the PET signaling pathway via transcriptional activation of the positive regulators PAP1, (E)GL3 and TT8, and by repressing the MYBL2 transcript level (Fig.…”

“…Several Arabidopsis CK signaling pathway mutants have been used to investigate the role of CK in the regulation of anthocyanin accumulation. The double mutants ahk2/3 and ahk3/4 showed significant reduction of anthocyanin accumulation in response to treatment with Suc and CK (Das et al, 2012;Figs. 2A and 2B).…”

“…A recent finding that the photosynthetic electron transport (PET) chain, in addition to the well-characterized HY5-dependent signaling, plays an important role in light signaling pathways in green, vegetative leaf tissues (Das et al, 2011;Jeong et al, 2010) demonstrates the complexity of the cross-talk between various pathways. Sugar-induced anthocyanin biosynthesis is apparently modulated by the heterotrimeric M(L2)BW complexes that are under the regulation of hormones (Das et al, 2012;Jeong et al, 2010;Loreti et al, 2008;Shan et al, 2009), Fig. 1.…”

“…2; Supplemental Table S2). Some evidence has been provided that links CK signaling pathways with HY5 (Vandenbussche et al, 2007;Das et al, 2012). It may be that the CK-responsive GATA factor 1 is responsible for this cross talk.…”

Roles for Light, Energy, and Oxygen in the Fate of Quiescent Axillary Buds

The hierarchy of events governing the resumption of growth of a quiescent axillary bud are poorly understood. During quiescence, a homeostasis exists in phytohormone and source/sink regulation, which represses the metabolic and mitotic progression of the bud. Environmental change and shoot development can alter the homeostasis, leading to a binary state change and the commitment to growth. Within this context, light and oxygen availability can serve both metabolic and signaling functions. However, the question of substrate versus signal has proven challenging to resolve; in the case of sugars, there are disparities in the data from apical and axillary buds in juvenile shoots, while in postdormant perennial buds, light has only a facultative role in the decision, but signaling may still be essential for bud fate. We briefly update the roles and hierarchies of light-, energy-, and oxygen-dependent functions in axillary bud outgrowth of annual shoots, before focusing discussion on the role of chloroplast-to-nucleus retrograde signaling genes such as GENOMES UNCOUPLED4 (GUN4) and ELONGATED HYPOCOTYL5 (HY5) in bud burst responses to light, examining available transcriptome data from postdormant grapevine (Vitis vinifera) buds. We discuss the evidence implicating cryptochromes (CRY) in the activation of HY5 expression in grapevine, leading to chloroplast biogenesis in the buds, and that

Date palm (Phoenix dactylifera) fruit (dates) are an economically and culturally significant crop in the Middle East and North Africa. There are hundreds of different commercial cultivars producing dates with distinctive shapes, colors, and sizes. Genetic studies of some date palm traits have been performed, including sex determination, sugar content, and fresh fruit color. In this study, we used genome sequences and image data of 199 dry dates (Tamar) collected from 14 countries to identify genetic loci associated with the color of this fruit stage. Here, we find loci across multiple linkage groups (LG) associated with dry fruit color phenotype. We recover both the previously identified VIRESCENS (VIR) genotype associated with fresh fruit yellow or red color and new associations with the lightness and darkness of dry fruit. This study will add resolution to our understanding of date color phenotype, especially at the most commercially important Tamar stage.
