Summary: Microbial communities associated with plants play a vital role in plant growth regulation and disease control. This study investigated the effects of preharvest treatment with Aureobasidium pullulans S2 on the fungal and bacterial communities on tomato surfaces, and found that it significantly altered the microbial composition and potentially beneficial genera. Further research is needed to understand the functions of these taxa and utilize them for targeted microbial manipulation in fruits and vegetables.

Summary: The redundancy and interplay among transcriptional regulators of floral development play a crucial role in ensuring plant reproductive success and crop production. This study reveals an additional layer of complexity in the regulation of floral meristem identity and flower development, linking carotenoid biosynthesis and metabolism to the determinate flowering regulation. The accumulation and cleavage of various ?-carotenes in the clb5 mutant of Arabidopsis leads to the reprogramming of gene regulatory networks, establishing floral meristem identity similar to the master regulator APETALA1 (AP1). The findings also suggest that this link between carotenoid metabolism and floral development is conserved in tomato, involving AP1 and SEPALLATA3 (SEP3) as redundant regulators of floral meristem identity.

Summary: The study demonstrates that the application of A. pullulans S-2 effectively controls postharvest diseases in tomatoes by inhibiting decay, maintaining fruit firmness, and reducing weight loss. The treatment group also showed changes in bacterial and fungal community composition, with certain pathogens being significantly reduced. This provides new insights into using microbial antagonists for controlling fruit diseases.

Summary: Drought stress is a major factor affecting agricultural production by negatively impacting plant growth and metabolism. Previous research has shown that viruses, such as the tomato yellow leaf curl virus, can enhance a plant's ability to tolerate both drought and heat stress. However, the underlying mechanisms for this induced drought tolerance need further investigation.

Summary: Tomatoes are highly demanded in almost every country due to their gastronomic versatility and nutritional value. Factors such as drought, salinity, and inadequate temperature can decrease tomato yield and affect various metabolic pathways. Biotechnological tools can be used to alter tomato genes and improve its adaptability to abiotic stress. Biomimetic biotechnological approaches (BBA), which imitate nature's solutions, have gained attention for developing sustainable strategies to enhance tolerance in plants. In this review, genetic sequences and molecules that were targets of biotechnological intervention in tomatoes are discussed, along with the implications and perspectives within the GMO debate.

Summary: The study reveals the essential role of SlPIF3 in regulating pollen development in tomato, and demonstrates that SlGLT1 and SlCWIN9 colocalise with SlPIF3 in anthers and are directly regulated by it, with knockout of SlPIF3 leading to pollen development arrest. The fertility of Slpif3 lines is partially restored in a dose-dependent manner by exogenous auxin indole-3-acetic acid, highlighting a new strategy for creating hormone-regulated genic male sterile lines for tomato hybrid seed production.

Summary: Research showed that abaxial leafy supplemental lighting (AB) can enhance net photosynthetic rate and stomatal conductance in tomato plants compared to adaxial leafy supplemental lighting (AD). However, the underlying regulatory mechanisms remain unclear. In this study, transcriptomic and proteomic changes in tomato leaves were assessed under AB and AD, revealing differential expression of 7352 genes and 152 proteins. Significant differences were observed in genes and proteins related to various pathways, including cell processes, metabolism, regulation, genetic information processing, and organismal systems. The upregulation of key genes involved in hormone signaling, light perception, photosynthesis, plant fitness, and fruit ripening explained the positive effects of AB on plant growth and development. qPCR confirmed the upregulation of genes involved in auxin response, gibberellin synthesis, cell cycle regulation, sugar transport, and fruit ripening. These findings contribute to understanding plant light response mechanisms and identifying genes for efficient light energy utilization.

Summary: This study analyzed the spatiotemporal distribution of Tomato brown rugose fruit virus (ToBRFV) in commercial tomato greenhouses and found that logistic models best described the temporal progress of the virus. The disease exhibited slightly aggregated patterns in the initial phase, highly aggregated in the exponential phase, and uniform in the deceleration and stationary phases, with important implications for disease monitoring, diagnosis, management, and risk prediction.

Summary: High night temperature (HNT) has negative effects on rice yield, mainly by reducing spikelet number per panicle leading to yield decrease. HNT enhances nighttime reduction of non-structural carbohydrates (NSC) in stem tissue, negatively correlated with yield. HNT weakens the relationship between NSC remobilization and harvest index.

Summary: Ectopic expression of glutaredoxin S17 from Arabidopsis thaliana (AtGRXS17) in maize enhances chaperone activity and gene expression associated with heat stress, providing thermotolerance. Thermotolerant maize lines showed increased protection against protein damage, resulting in a sixfold increase in grain production under heat stress conditions. These lines also exhibited thermotolerance in the reproductive stages, leading to improved pollen germination and fertilized ovules. The findings offer a robust and simple strategy for meeting rising yield demands in maize and potentially other crop species in a warming global environment.

Summary: Exposure to high temperatures can affect pollen development, but a study shows that reducing the hormone salicylic acid (SA) levels in tomatoes can increase pollen viability under long-term mild heat conditions. This increase in thermotolerance is associated with enhanced jasmonic acid (JA) signaling.
