The Dynamic Transcriptome: Using Clustered Time Points to Tease Apart Rice Tiller Angle Control
Blog, The Plant Cell, The Plant Cell: In BriefGiven the importance of branch angle in determining overall plant form, we know surprisingly little about how those angles are controlled. Branch angle clearly has genetic underpinnings but also responds strongly to light and gravity, as well as to water availability and other stimuli (reviewed in Roychoudhry…
