The phytochemical indole-3-carbinol is produced in Cruciferous plants upon tissue rapture and deters herbivores. We recently showed that indole-3-carbinol modulates auxin signaling in root tips. Here we present transcript profiling experiments which further reveal the influence of indole-3-carbinol on auxin signaling in root tips, and also show that I3C affects auxin transporters. Brief treatment with indole-3-carbinol led to a reduction in the amount of PIN1 and to mislocalization of PIN2.

As an important starch crop, sweet potato has significant practical importance for maintaining food security worldwide. This study identified differential expressed genes associated with the expansion of tuberous roots by comparing the transcriptome across tuberous roots at the initial period (initiated tuberous roots (ITRs), rapid expansion period (tuberous roots (TRs), fibrous roots (FRs) at the seedling stage, and fibrous roots at the adult stage (unexpanded FRs (UFRs)). sRNA-seq and degradome analyses were performed to reveal the role of miRNAs in tuberous root development in sweet potato.

Specific cultivars of many commercial fruit tree undergo cycles of heavy fruit load (ON-crop) one year, followed by low fruit load (OFF-crop) the next (termed alternate bearing). Fruit load may affect flowering at various developmental stages, and its presence is suggested to generate a flowering-inhibitory signal. In a previous report, we showed that the presence of fruit induces polar auxin transport from the fruit into the stem, interfering with indole acetic acid (IAA) release from the bud, and thus elevating its levels in the bud meristem.

Since plant viruses cause lifelong infections, virus-plant interactions are exposed to large temperature fluctuations in evergreen perennials. In such circumstances, virus-plant interactions are expected to change significantly between the warm and cold seasons. However, few studies have investigated the effects of cold temperatures on virus-plant interactions.

Background: Many different stress signaling pathways converge in a common response: slowdown or arrest cell cycle in the G1 phase. The G1/S transition (called Start in budding yeast) is a key checkpoint controlled by positive and negative regulators. Among them, Whi7 and Whi5 are transcriptional repressors of the G1/S transcriptional program, yeast functional homologs of the Retinoblastoma family proteins in mammalian cells.

Aquaporins are widely present in the plant kingdom and play important roles in plant response to abiotic adversity stresses such as water and temperature extremes. In this study, we investigated the regulatory role of NTPIP2;4 on drought tolerance in tobacco at physiological and transcriptional levels. In this experiment, we constructed an NtPIP2;4 overexpression vector and genetically transformed tobacco variety 'K326' to investigate the mechanism of NtPIP2;4 gene in regulating drought tolerance in tobacco at physiological and transcriptomic levels.
