Gallbladder cancer (GBC) is an aggressive malignancy with a poor prognosis, often diagnosed at advanced stages due to subtle early symptoms. Recent studies have provided a comprehensive view of GBC's genetic and mutational landscape, uncovering crucial pathways involved in its pathogenesis. Environmental exposures, particularly to heavy metals, have been linked to elevated GBC risk.

Small RNA sequencing analysis in two chickpea genotypes, JG 62 (Fusarium wilt-susceptible) and WR 315 (Fusarium wilt-resistant), under Fusarium wilt stress led to identification of 544 miRNAs which included 406 known and 138 novel miRNAs. A total of 115 miRNAs showed differential expression in both the genotypes across different combinations. A miRNA, Car-miR398 targeted copper chaperone for superoxide dismutase (CCS) that, in turn, regulated superoxide dismutase (SOD) activity during chickpea-Foc interaction.

Balanced plant nutrition and optimal micro-climate are critical for achieving higher production sustainably. Substituting mineral fertilizers with organic amendments under water-conserving strategies like mulch can enhance the quality and yield and improve soil health. Therefore, a two-year study was conducted to examine the synergistic effects of mulch and reducing inorganic fertilizers and partially substituting organic amendments on essential oil (EO) yield and its composition, and soil properties in Salvia sclarea, an industrially important crop.
