CmTCP20 Plays a Key Role in Nitrate and Auxin Signaling-Regulated Lateral Root Development in Chrysanthemum.

Lateral root (LR) formation and development play a vital role in plant development by permitting the establishment of branched root systems. It is well known that nutrient availability controls LR development. Moreover, LR development is fine-tuned by a myriad of hormonal signals.

Chrysanthemum MADS-box transcription factor CmANR1 modulates lateral root development via homo-/heterodimerization to influence auxin accumulation in Arabidopsis.

Root system architecture is an important agronomic trait by which plants both acquire water and nutrients from the soil and adapt to survive in a complex environment. The adaptation of plant root systems to environmental constraints largely depends on the growth and development of lateral roots (LRs). MADS-box transcription factors (TFs) are important known regulators of plant growth, development, and response to environmental stimuli.

[Effects of nitrogen fertilization on the nitrogen uptake, accumulation, and seed quality of oil peony].

Field experiments, including four levels of N application 0, 18, 24, 30 g N·m, were carried out to clarify the effects of nitrogen fertilization on N accumulation and translocation in lea-ves as well as the seed quality of oil peony (Paeonia ostii 'Fengdan Group'). The results showed that the nitrogen application significantly increased the height, canopy, flower diameter and flower dry mass. The heights under the treatments 24 and 30 g N·m increased by 14.
