Unraveling the mechanisms behind salt stress alleviation and enhanced fruit storability in pomegranate through triacontanol treatment

Emad Hamdy Khedr, Nagwa Khedr

Summary: This study found that applying triacontanol (TRA) at concentrations of 10 and 20 µM three times proved to be the most effective treatments in mitigating the harmful effects of salt stress on pomegranate trees. TRA treatment preserved the plant's nutrient and antioxidant content, increased productivity, and enhanced post-harvest storability of fruits. TRA treatments resulted in higher concentrations of mineral nutrients, porphyrin concentration, activities of CAT, POD, and SOD, and various other beneficial effects.

Estimation of above ground biomass, biophysical and quality parameters of spinach (Spinacia Oleracea L.) using Sentinel-2 to support the supply chain

Andrea Marcone, Giorgio Impollonia, Michele Croci, Henri Blandinieres, Stefano Amaducci

Summary: This study used Sentinel-2 satellite images to estimate biophysical and biochemical parameters of spinach crops and found that canopy-level parameters were estimated more accurately. The estimation of the canopy-scale parameter AGB using MCARI showed the highest accuracy, while the estimation of the leaf-scale parameter LCC using NDWI showed the lowest accuracy. At the field scale, the validation results for AGB estimation using SR were the best.

Preharvest 1-methylcyclopropene (1-MCP) treatment effects on quality of spot and strip picked 'Gala' apples at harvest and after storage as affected by postharvest 1-MCP and temperature conditioning treatments

Franziska C. Doerflinger, Yosef Al Shoffe, Gilang Sutanto, Jacqueline F. Nock, Christopher B. Watkins

Summary: This study found that early harvest and preharvest 1-MCP treatment contribute to reducing the risk of flesh browning (FB) development during storage of 'Gala' apples, as evidenced by lower FB incidence. Conditioning, postharvest 1-MCP treatment, and selective picking also resulted in reduced FB incidence to a lesser extent. The study highlights the importance of preharvest and postharvest treatments in preventing FB in stored apples.

ABC transporter SlABCG23 regulates chilling resistance of tomato fruit by affecting JA signaling pathway

Ning Tao, Yuhan Liu, Qingyu Shi, Qingguo Wang, Qingqing Li

Summary: In this study, we investigated the effect and mechanism of an ATP-binding cassette transporter, SlABCG23, on the chilling resistance of tomato fruit during storage. We found that mutation of SlABCG23 resulted in severe chilling injury, decreased jasmonic acid contents, and increased expression levels of the JA signaling inhibitor, SlJAZ6. This mutation also led to a decrease in fruit pericarp thickness, lower expression levels of cold response genes, and reduced antioxidant enzyme activities.

SlCNR regulates postharvest water loss and wax accumulation in tomato fruit and directly represses the transcription of very-long-chain (VLC) alkane biosynthesis-related genes SlCER1-2 and SlCER6

Di Chen, Tingyu Wang, Hua Huang, Qiaoli Zhang, Xue Chen, Zongyan Sun, Yanping Song, Yuetong Yi, Chengxia Liu, Donald Grierson, Jiankang Cao, Daqi Fu, Hongliang Zhu, Guiqin Qu

Summary: In this study, the researchers found that the tomato SBP-box protein SlCNR plays a role in regulating fruit wax accumulation and postharvest water loss. The overexpression of SlCNR led to decreased wax accumulation and increased water loss, while the knockout of SlCNR resulted in increased wax accumulation and decreased water loss. RNA-seq analysis revealed that SlCNR directly repressed the expression of wax biosynthetic genes, such as SlCER1-2 and SlCER6. These findings provide new insights into the genetic regulatory mechanisms of fruit wax accumulation in tomatoes.
