This is from the Editorial Office of?Phyton-International Journal of Experimental Botany.?We are pleased to share with you three high quality research papers published in our journal by Professor Fadi Chen?and his team at Nanjing Agricultural University, which report their new progress in research on chrysanthemum.

Article details are as follows:

B Class Floral Homeotic Genes are Involved in the Petal Identity and Flower Meristem Determinations in Chrysanthemum morifolium

This study provides insights into the functions of class B genes in flower development, and is informative for dissecting the molecular mechanisms of flower development in chrysanthemum.

Comparative Non Participating Transcriptome Analysis Response to Low Phosphorus by CmPht1;2?in Chrysanthemum

This research will be helpful for elucidating the mechanism of effects by?CmPht1;2?overexpression on growth, development and stress tolerance.

Figure 6: DEGs enriched by KEGG pathway in roots between Oe1 and WT under 2 d LP-stress. The metabolic pathway maps refer to Arabidopsis in KEGG database. The Up-regulated KEGG Orthology (KO) nodes were labeled with red frames. The bar chart shows the relative expression differences of adjacent genes

Brassinosteroid Biosynthetic Gene?CmDWF4?Regulates Bud Outgrowth in?Chrysanthemum morifolium

This work establishes a mechanism by which BR biosynthetic gene?CmDWF4?promotes lateral bud outgrowth in chrysanthemum, possibly through regulating cell elongation and expansion.

Figure 4: Effects of CmDWF4 on lateral bud initiation and outgrowth after decapitation. (A) Lateral bud outgrowth phenotypes of overexpressed CmDWF4 lines in the ‘Jinba’ background after decapitation for 6 days. Scale bars represent 1.0 cm. (B) Statistics of the total length of the first three lateral buds. Data are presented as means ± SE (n = 6). (C) qRT-PCR analysis of relative expression of CmDWF4 in transgenic lines. Data are presented as means ± SE (n = 3). Significant variations from WT are indicated with asterisks (**p < 0.01)

I would like to invite you to read these articles and share your thoughts with us.

Thank you for your time and attention.

Sincerely,
