Validation of molecular response of tuberization in response to elevated temperature by using a transient Virus Induced Gene Silencing (VIGS) in potato.
Article in Functional & integrative genomics, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Temperature plays an important role in potato tuberization. The ideal night temperature for tuber formation is ~17 °C while temperature beyond 22 °C drastically reduces the tuber yield. Moreover, high temperature has several undesirable effects on the plant and tubers. Investigation of the genes involved in tuberization under heat stress can be helpful in the generation of heat-tolerant potato varieties. Five genes, including StSSH2 (succinic semialdehyde reductase isoform 2), StWTF (WRKY transcription factor), StUGT (UDP-glucosyltransferase), StBHP (Bel1 homeotic protein), and StFLTP (FLOWERING LOCUS T protein), involved in tuberization and heat stress in potato were investigated. The results of our microarray analysis suggested that these genes regulate and function as transcriptional factors, hormonal signaling, cellular homeostasis, and mobile tuberization signals under elevated temperature in contrasting KS (Kufri Surya) and KCM (Kufri Chandramukhi) potato cultivars. However, no detailed report is available which establishes functions of these genes in tuberization under heat stress. Thus, the present study was designed to validate the functions of these genes in tuber signaling and heat tolerance using virus-induced gene silencing (VIGS). Results indicated that VIGS transformed plants had a consequential reduction in StSSH2, StWTF, StUGT, StBHP, and StFLTP transcripts compared to the control plants. Phenotypic observations suggest an increase in plant senescence, reductions to both number and size of tubers, and a decrease in plant dry matter compared to the control plants. We also establish the potency of VIGS as a high-throughput technique for functional validation of genes.
