We thank Jin and Zhu for their comments (1). Our study in PNAS focuses on the molecular role for PINOID (PID) and PID-mediated CONSTITUTIVELY PHOTOMORPHOGENIC 1 (COP1) phosphorylation in the regulation of seedling development in Arabidopsis (2). Not only hypocotyl elongation but also apical hook maintenance and cotyledon aperture are phenotypic readouts for photomorphogenesis in Arabidopsis (3,...

Plant photoreceptors mediate light suppression of the E3 ubiquitin ligase COP1 (CONSTITUTIVE PHOTOMORPHOGENIC 1) to affect gene expression and photomorphogenesis. However, how photoreceptors mediate light regulation of COP1 activity remains unknown. We report here that Arabidopsis blue-light receptor cryptochrome 1 (CRY1) undergoes blue-light-dependent interaction with the COP1-interacting prot...

Cryptochrome 1 (CRY1), a main blue light receptor protein, plays significant role in several biological processes. However, the expression patterns and function of CRY1 strawberry have not been identified. Here, profile different tissues developmental stages fruit, response to abiotic stresses (low temperature, salt drought) were analyzed. Its subcellular localization, interaction proteins hete...

The COP9 signalosome is a highly conserved eight-subunit protein complex initially defined as a repressor of photomorphogenic development in Arabidopsis. It has recently been suggested that the COP9 signalosome directly interacts and regulates SCF type E3 ligases, implying a key role in ubiquitin-proteasome mediated protein degradation. We report that Arabidopsis FUS11 gene encodes the subunit ...

Morphogenic potential of cabbage cv. Pride of India, for multiple shoot induction was tested under in vitro conditions using cotyledon and hypocotyl explants. Aseptically grown seven to nine days old seedlings of cabbage were used as source of explants for reproducible plant regeneration studies. Forty different concentrations and combinations of TDZ (alone), TDZ with adenine, TDZ with NAA and ...

Flavonols constitute a group of flavonoids with important photoprotective roles in plants. In addition, flavonol content and composition greatly influences fruit quality. We previously demonstrated that the grapevine R2R3-MYB transcription factor (TF) VviMYBF1 promotes flavonol accumulation by inducing the expression of flavonol synthase (VviFLS1/VviFLS4), a key step of the initial flavonol pat...
