Growth of tomato fruits is determined by cell division and cell expansion, which are tightly controlled by factors that drive the core cell cycle. The cyclin-dependent kinases (CDKs) and their interacting partners, the cyclins, play a key role in the progression of the cell cycle.

2023年5月31日 · They have a fleshy pericarp, which is the wall of the fruit, surrounding the seeds. The pericarp is divided into three main layers: the exocarp (outermost layer), the mesocarp (middle layer), and the endocarp (innermost layer).

Most cultivated varieties except cherry tomatoes have four or five locules. The locules are surrounded by the pericarp. The pericarp includes the inner wall, columella; the radial wall, septa; and the outer wall. The pericarp and the placenta comprise the fleshy tissue of the tomato.

2023年4月4日 · Tomato is the most studied species for fleshy fruit development and quality, both as a model system and because of its economic value (van der Knaap and Østergaard 2018; Mauxion et al. 2021). Its fruit is a berry whose main tissue, …

1. Pericarp: The pericarp refers to the wall of the fruit that surrounds the seeds. In tomatoes, the pericarp is fleshy and consists of three main layers – the exocarp, mesocarp, and endocarp. 2. Exocarp: The exocarp is the outermost layer of the tomato …

Our results demonstrate that endogenous CKs regulate pericarp growth and development, and subsequently fruit size. To investigate the effects of endogenous CKs on tomato fruit growth and development, three independent transgenic lines (L6, L11, …

Tomato pericarp was observed on resin equatorial sections of ovaries at floral stages 11 (A) and anthesis (B), and of fruits at 4 DPA (C) and 36 DPA (D).

A pericarp is a fraction of the fruit that constitutes the outer layer in the fruit anatomy, which encloses the seed. This post focuses on the meaning, three distinct layers, functions and some salient features of the pericarp.

2017年3月28日 · The cell layer-based analysis of tomato pericarp development helps in the terminology for pericarp patterning. The terms exocarp, mesocarp, and endocarp are widely used to designate specific regions in pericarp.

The result is a synthetic representation of cell morphology variations within the whole fruit. The method was applied to the characterization of cell morphology in tomato pericarp. Two different imaging scales that provided complementary descriptions were used: 3D …

2022年1月19日 · Here, we report that the reduction in levels of endogenous active CKs via overexpression of the CK-inactivating enzyme gene AtCKX2 specifically in fruit tissues resulted in reduced pericarp thickness and smaller fruit size compared with wild-type control fruits.

2025年1月1日 · TKN3 was found to be expressed in the tomato ovary wall/pericarp of zero to two days post-anthesis fruits as a KNOX I class member, but its function in fruit development was elusive. Here, we found that mutations of TKN3 by CRISPR/Cas9 caused fruit developmental defects, and fruit weight was dramatically reduced in the tkn3cr mutant.

2014年5月21日 · In this paper, we assess the applicability of putative mechanisms for the onset of endoreduplication in tomato pericarp cells via development of a mathematical model for the cell cycle gene regulatory network.

Tomato pericarp was used as a model for fleshy fruits. Two different scales were investigated through 3D imaging using confocal microscopy, and macroscopy imaging of pericarp slices.

Tomato is the most studied species for fleshy fruit devel-opment and quality, both as a model system and because of its economic value (van der Knaap and Østergaard 2018; Mauxion et al. 2021). Its fruit is a berry whose main tis-sue, the pericarp, arises from the ovary wall.

2017年4月1日 · In this study, changes in pectin and hemicellulose chemical characteristics and location were investigated in the pericarp tissue of tomato (Solanum lycopersicon var Levovil) at four stages of development (7, 14 and 21 day after anthesis (DPA) and mature green stages).

In this study, changes in pectin and hemicellulose chemical characteristics and location were investigated in the pericarp tissue of tomato (Solanum lycopersicon var Levovil) at four stages of development (7, 14 and 21day after anthesis (DPA) and mature green stages).

2021年8月14日 · Our results demonstrate that fruit growth in tomato requires balanced expression of the novel cell size regulator SlPZF1. SlPZF1 encodes a member of C 2 H 2 zinc finger protein family, preferentially expressed in the pericarp during tomato fruit development.

Cellular organization of tomato pericarp at the mature green stage. Semi-thin section (1.5 μm thick) of tomato pericarp stained by toluidine blue. Oe, outer epidermis; m, mesocarp; vb,...

Growth of tomato fruits is determined by cell division and cell expansion, which are tightly controlled by factors that drive the core cell cycle. The cyclin-dependent kinases (CDKs) and their interacting partners, the cyclins, play a key role in the progression of the cell cycle.
