However, when temperature exceeds 30 °C, heads become loose and branchy, tend to develop leaf-like structures, and initial floret development is disrupted (Bjorkman and Pearson 1998).
In the present study, RNA-Seq was performed on samples from different stages of leaf development, and the global changes in the developing leaf transcriptome were analyzed.
Although the analysis of tissue-specific PHYB YFP lines reveals the spatial requirement for phyB during stomatal development, it does not distinguish between a local requirement within a developing leaf and a systemic role in existing mature leaves.
A young developing leaf before it is photosynthetic is a sink for sugars produced by older leaves.
Digel, B., Pankin, A. & von Korff, M. Global transcriptome profiling of developing leaf and shoot apices reveals distinct genetic and environmental control of floral transition and inflorescence development in barley.
In this study, we measured cellular- and tissue-scale kinetics of molecular transport through plasmodesmata in Arabidopsis thaliana developing leaf primordia by fluorescence recovery assays.
As of right now the plants that are at the R4 growth stage are at an average length of 2 cm long at one of the four uppermost nodes on the main stem with a fully developed leaf.
The plants that are at the R5 growth stage has pods that are 3mm in length and is at one of the four uppermost nodes on the main stem with a fully developed leaf.
h The SAM continues to grow in size, surrounded by a developing leaf primordium.
Scale bars = 1 μm. Figure 2 Microscopic observations of transverse sections of fully developed leaf blades of seedlings.
Maximum leaf area of the youngest fully developed leaf also strongly correlated with shoot P content (r 2 = 0.71, P < 0.00001).
