Invertase of the cell wall controls the growth of both the apical and vegetative organs of the tomato

Researchers have intensively studied how external factors like temperature, humidity, soil structure, and fertilizer affect tomato plant growth. However, little is known about how internal factors, particularly cell wall invertase, affect plant growth. This study aims to determine how the activity of the cell wall invertase enzyme regulates the apical and vegetative growth of plants. The study utilized four tomato plants, consisting of two transgenic and two wild-type plants. The transgenic plants in one set exhibit lower levels of the cell wall invertase, known as TLINA. Another set of transgenic plants, known as TINHI, exhibited higher levels of the cell wall invertase. We named both wild types of plants, WLINA and WINHI, respectively, and used them as the control plant. The study's results revealed that the transgenic plants (TLINA) ceased their apical shoot growth, leading to the growth of an axial shoot to take the place of the apical shoot. t. Also, the TLINA plants grew lower than wild-type plants. Interestingly, the vegetative organs of TINHI plants grew higher than both wild types and TLINA plants. This evidence suggested that cell wall invertase regulates the apical and vegetative organs of plants.
