A whole plant is composed of two main organ systems: the shoot and the root. The shoot system is the aerial part, whereas the root system is the underground part. Each organ system is composed of various specialized organs. Stem, leaf, flower, and fruit are organs that make up the shoot...

or branches that reiterate the main shoot system. In the reproductive phase of development,inflorescencemeristems produce floral meristems, which produce floral organs. Continual organ initiation allows plant architecture to be flexible and respond to changing environmental conditions, resulting in plants ...
upon dead host tissues and is also activated by beneficial microorganisms which colonize the plant root system and the root-soil interface known as the rhizosphere71. SAR and ISR inhibit the response of the other due to the antagonistic relationship between their respective signaling hormones SA and...
An early scientific classification of tissues divided them on the basis of the organ system of which they formed a part (e.g., nervous tissues). Embryologists have often classified tissues on the basis of their origin in the developing embryo; i.e., ectodermal, endodermal, and mesodermal...
The expression of the flg22 receptor FLS2 in pWER::FLS2-GFP is limited to the root epidermis such that potential interorgan shoot-to-root signal after flg22 perception is minimized. The plates were sealed with 3M tape and transferred to the phytochamber for incubation. One week after ...
(generally pg/g FW). Thus, very sensitive analytical methods are required for their detection. However, levels of GAs may vary substantially even within a plant organ. Vegetative tissues (stems, roots and leaves) typically contain several pg/g FW, while reproductive organs (such as seeds and ...
that serves as a storage organ used by some plants to survive winter or other adverse conditions such as summer drought and heat (estivation). Comparison of the corm and the bulb • Corms are often similar in appearance to bulbs externally, and ...

The skin, being the largest organ, serves as the primary defense against external factors like ultraviolet radiation, oxidative stress, and physical injuries. However, when exposed to the external environment, the skin is vulnerable to harm. As mentioned earlier, PDNVs have the potential to combat...
