ABSTRACT

Investigation of Anthocyanin Localization in Various Parts ofImpatiens BalsaminaL.

“…In higher plants, accumulation of anthocyanins generally occurs in specifi c tissues or cells during a specifi c stage (14,21). The accumulation of anthocyanins seen in various tissues and organs in the vegetative stage is considered as an indicator against biotic and abiotic stress (4,6,7,10,20,41,42). Anthocyanin biosynthesis in plants also appears to be under manifold controls (18,19,25,30).…”

The Role of Nitric Oxide in Plants

“…Takahashi and Yamasaki (56) showed that NO suppressed ATP synthesis and electron transport in chloroplasts, and that NR-generated NO inhibited photosynthesis. On the other hand, the application of NO donors in some plants, such as lettuce, red cabbage and Arabidopsis, increased chlorophyll content (5,11). It was shown that NO increased chlorophyll content, especially in the guardian cells of pea leaves (38), and inhibited chlorosis in NO-treated wild corn (28).…”
