Experiments on seedlings, which strongly affect productivity, were conducted to obtain cotyledon unfolding time and the time series projected area of cotyledons and true leaves of individual seedlings of romaine lettuce (Lactuca sativa L. var. longifolia), using RGB images. Thi...
The first leaves, also called cotyledons, generally start yellowing at the 3-week mark, when the second and third sets of leaves have fully developed. This is normal. However,yellowing of the true leaves is a cause for concernand a sign that your seedlings may be overwatered or need fert...
Directional auxin transport and formation of auxin maxima are critical for embryogenesis, organogenesis, pattern formation, and growth coordination in plants, but the mechanisms underpinning the initiation and establishment of these auxin dynamics are no

A simple and efficient method was established for isolating protoplasts from rapeseed cotyledons and leaves, and found that cotyledons might be better than true leaves. Transient expression analysis showed that yellow fluorescent protein (YFP) and luciferase (LUC) could be expressed in rapeseed ...

In soybean, both cotyledons and leaves develop the capacity for photosynthesis, and subsequently senesce and abscise once their function has ended. Before this occurs, the nutrients they contain are mobilized and transported to other parts of the plant. These processes are carefully orchestrated by ...
In the early stages of seedling growth, assimilates were directed mainly to the lower stem and root system, then to the shoot apex and immature leaves, and finally again to the root system as the first true leaf assumed the function of supplying assimilates during cotyledonary senescence....
