“…We examined changes in the expression levels of these four genes in Col-0 and myb30 roots exposed to control and 5 µM ABA treatments for 24 h using RT-qPCR (Figure 4(a)). All four genes were strongly downregulated in myb30 roots, which was consistent with our previous results [13]. Furthermore, LTP5 and LTPG1 but not LTPG2 and PME44 were significantly upregulated by ABA treatment in Col-0 roots.…”

“…In Col-0 wild-type but not myb30 plants, MYB30 was upregulated by ABA treatment in the RT-qPCR analysis (Figure 2(a)). However, the induction level of MYB30 by ABA was weaker than that by H 2 O 2 treatment when we compared MYB30 expression level with that of our previous dataset [13]. …”

Reactive oxygen species (ROS) and plant hormones play important roles in regulating plant growth and stress responses as signaling molecules. Abscisic acid (ABA) is known as the key regulator of both abiotic and biotic stress responses. During stress responses, ABA is known to regulate ROS production, indicating that important crosstalk occurs between ROS and ABA signaling. We recently reported that MYB30, an MYB-type transcription factor, regulates root cell elongation under ROS signaling. In this study, we analyzed the molecular interaction between ROS and ABA signal during for root development, which is mediated through MYB30 transcriptional regulation. We showed that MYB30-regulated root cell elongation was mediated by ROS production under ABA signaling. Our findings will provide one piece of evidence of the complex cross talk between ROS and hormone signaling that regulates root development.

Role of hydrogen peroxide receptors in endocarp browning of postharvest longan fruit

Longan (Dimocarpus longan) is an important subtropical evergreen fruit tree (family Sapindaceae) in southern China and exhibits a high commercial and nutritional value. Endocarp browning of longan fruit once harvested considerably reduces the commercial value. The excessive accumulation of reactive oxygen species (ROS) can induce the rapid endocarp browning of longan fruit during storage, but the ROS‐mediated mechanism remains relatively unclear. In this investigation, a hydrogen peroxide scavenger, 1,3‐dimethylthiourea (DMTU), was used to treat longan fruit to elucidate the physiological and molecular bases of the ROS‐mediated endocarp browning of longan fruit. Application of 5 mM DMTU significantly delayed endocarp browning, inhibited respiration rate, suppressed the accumulations of H2O2 and malondialdehyde (MDA), and activated the antioxidant system of longan fruit during storage, such as 3.8 of the DMTU‐treated fruit versus 1.6 of non‐DMTU‐treated fruit of the browning index, 398 versus 346 μg kg−1 S−2 of the respiration rate, and 47.5 versus 37.8 nmol g−1 of the MDA content after 6 days of storage. Furthermore, the DMTU treatment significantly affected the expression levels of the H2O2 receptors and hydrogen peroxide‐induced Ca2+ increases (HPCA)‐LIKEs (HPCALs). Additionally, the regulatory network comprising transcription factors controlling the HPCAL expression in longan was constructed. The major transcription factors, including GATA1, GATA28, TCP20, and AGL20, may contribute to the ROS‐mediated endocarp browning of longan fruit during storage by regulating the HPCAL expression levels. This study could provide new insights into the involvement of the HPCALs in the ROS‐mediated endocarp browning of longan fruit during storage.
