SlTCP29 and SlTCP24 participate in the morphological development of tomato compound leaves by integrating multiple pathways.

Leaves are the primary vegetative organs of plants, and their morphology is an important trait affecting plant architecture, light energy utilization, environmental adaptation, and fruit quality and yield. Leaf development is highly flexible; however, understanding the regulatory mechanisms of factors coordinating leaf morphogenesis and differentiation remains limited. In this study, we obtained a double mutant for SlTCP29 and SlTCP24 genes from the CRISPR/Cas9 mutant population, both belonging to the CINCINNATA-like TCP (TEOSINTE BRANCHED, CYCLOIDEA and PCF1/2) transcription factor subfamily.

Manipulation of artificial light environment improves plant biomass and fruit nutritional quality in tomato.

Introduction: The yield and quality of tomato (Solanum lycopersicum. L) are often decreased when plants suffer from low light intensity and short-photoperiod in winter. Manipulation of the artificial light environment is a feasible technology to promote off-seasonal production and improve fruit nutritional quality in the greenhouse.

CPK10 regulates low light-induced tomato flower drop downstream of IDL6 in a calcium-dependent manner.

Flower drop is a major cause for yield loss in many crops. Previously, we found that the tomato (Solanum lycopersicum) INFLORESCENCE DEFICIENT IN ABSCISSION-Like (SlIDL6) gene contributes to flower drop induced by low light. However, the molecular mechanisms by which SlIDL6 acts as a signal to regulate low light-induced abscission remain unclear.

Transcriptomic Analysis of the Molecular Mechanism Potential of Grafting-Enhancing the Ability of Oriental Melon to Tolerate Low-Nitrogen Stress.

Nitrogen is the primary nutrient for plants. Low nitrogen generally affects plant growth and fruit quality. Melon, as an economic crop, is highly dependent on nitrogen.

Multiple transcription factors involved in the response of Chinese cabbage against .

Clubroot disease, which is caused by the obligate biotrophic protist , leads to the formation of galls, commonly known as pathogen-induced tumors, on the roots of infected plants. The identification of crucial regulators of host tumor formation is essential to unravel the mechanisms underlying the proliferation and differentiation of within plant cells. To gain insight into this process, transcriptomic analysis was conducted to identify key genes associated with both primary and secondary infection of in Chinese cabbage.

SlBEL11 regulates flavonoid biosynthesis, thus fine-tuning auxin efflux to prevent premature fruit drop in tomato.

Auxin regulates flower and fruit abscission, but how developmental signals mediate auxin transport in abscission remains unclear. Here, we reveal the role of the transcription factor BEL1-LIKE HOMEODOMAIN11 (SlBEL11) in regulating auxin transport during abscission in tomato (Solanum lycopersicum). SlBEL11 is highly expressed in the fruit abscission zone, and its expression increases during fruit development.

Light quality regulates plant biomass and fruit quality through a photoreceptor-dependent HY5-LHC/CYCB module in tomato.

Increasing photosynthesis and light capture offers possibilities for improving crop yield and provides a sustainable way to meet the increasing global demand for food. However, the poor light transmittance of transparent plastic films and shade avoidance at high planting density seriously reduce photosynthesis and alter fruit quality in vegetable crops, and therefore it is important to investigate the mechanisms of light signaling regulation of photosynthesis and metabolism in tomato (). Here, a combination of red, blue, and white (R1W1B0.

A molecular framework for controlled locule development of the floral meristem in tomato.

Malformed tomato fruit with multiple locules is a common physiological disorder that significantly affects the quality of tomatoes. Research has shown that the occurrence of malformed fruit in tomatoes is closely linked to the number of locules, and two key QTLs, and , are involved in controlling this trait. It has been observed that has a relatively weaker effect on increasing locule number, which is associated with two SNPs in the CArG repressor element downstream of the .

Effects of Low Temperature on Pedicel Abscission and Auxin Synthesis Key Genes of Tomato.

Cold stress usually causes the abscission of floral organs and a decline in fruit setting rate, seriously reducing tomato yield. Auxin is one of the key hormones that affects the abscission of plant floral organs; the () family is a key gene in the auxin biosynthesis pathway, but there are few research reports on the abscission of tomato flower organs. This experiment found that, under low temperature stress, the expression of auxin synthesis genes increased in stamens but decreased in pistils.

Exogenous melatonin enhances tomato heat resistance by regulating photosynthetic electron flux and maintaining ROS homeostasis.

Heat stress reduces plant growth and reproduction and increases agricultural risks. As a natural compound, melatonin modulates broad aspects of the responses of plants to various biotic and abiotic stresses. However, regulation of the photosynthetic electron transfer, reactive oxygen species (ROS) homeostasis and the redox state of redox-sensitive proteins in the tolerance to heat stress induced by melatonin remain largely unknown.

[Effects of nutrition medium on cucumber growth and soil microenvironment in greenhouse under continuous cropping].

An experiment of continuous cropping of cucumber in nutrition medium (composted with straw, rural soil and puffed chicken manure) or soil was conducted in greenhouse in order to study the effects of medium type on the cucumber growth and soil microenvironment, respectively. The results showed that the two treatments both displayed different levels of obstacles resulted from continuous cropping. In the same cropping season, the nutrient content, soil invertase and urease activities and B/F (bacteria/fungi) ratio in the nutrition medium were obviously higher but fungi quantity was lower than in the soil medium, suggesting the use of nutrition medium changed the bacterial population structure as to improve the cucumber growth and yield.
