The crosstalk of far-red energy and signaling defines the regulation of photosynthesis, growth, and flowering in tomatoes

Original language description

This study investigated the effect of light intensity and signaling on the regulation of far-red (FR)-induced alteration in photosynthesis. The low (LL: 440 mu mol m- 2 s- 1) and high (HL: 1135 mu mol m- 2 s- 1) intensity of white light with or without FR (LLFR: 545 mu mol m- 2 s- 1 including 115 mu mol m- 2 s- 1; HLFR: 1254 mu mol m- 2 s- 1 + 140 mu mol m- 2 s-1) was applied on the tomato cultivar (Solanum Lycopersicon cv. Moneymaker) and mutants of phytochrome A (phyA) and phytochrome B (phyB1, and phyB2). Both light intensity and FR affected plant morphological traits, leaf biomass, and flowering time. Irrespective of genotype, flowering was delayed by LLFR and accelerated by HLFR compared to the corresponding light intensity without FR. In LLFR, a reduced energy flux through the electron transfer chain along with a reduced energy dissipation per reaction center improved the maximum quantum yield of PSII, irrespective of genotype. HLFR increased net photosynthesis and gas exchange properties in a genotype-dependent manner. FR-dependent regulation of hormones was affected by light signaling. It appeared that PHYB affected the levels of abscisic acid and salicylic acid while PHYA took part in the regulation of CK in FR-exposed plants. Overall, light intensity and signaling of FR influenced plants&apos; photosynthesis and growth by altering electron transport, gas exchange, and changes in the level of endogenous hormones.
