Apart from advancing our understanding of how plants regulate their growth and shape, this research presents new questions for stem cell researchers in regards to cell size checkpoints and their importance during organism development.

The two drops moved away in opposite directions, a behaviour that mimics the «alternate» pattern of growth often seen in plants — for example, in the way leaves form on a stem.

If the concentration of the CDF4 protein would be too high in the stem cells, then the stem cells would also be forced to differentiate and the plant would have to stop root growth.

Soybean cultivars are often divided into two groups: indeterminate - tall plants whose main stem continues to grow after flowering - and determinate - shorter, bushier plants whose main stem halts growth when blossoms begin to form.

Removing the leaves from the top of the plant will encourage new growth down the stem.

I suggest you look up Liebig's Law of the Minimum, and also read up on the results of the FACE open air enhanced CO2 trials: higher CO2 promotes faster and more robust plant growth in only some species, but even then it mainly promotes increased production of cellulose and lignin in the plant stem and leaf structure rather than in increased fruit and seed yield.

Plant growth and yield parameters such as leaf area, stem dry weight, panicle dry weight, cob dry weight and grain number per cob were all significantly increased under elevated CO2.
