Systemic signaling of upper leaves promotes the induction of photosynthesis in lower leaves, allowing more efficient use of light flecks. However, the nature of the systemic signals has remained elusive. Here, we show that preillumination of the tomato (Solanum lycopersicum) shoot apex alone can accelerate photosynthetic induction in distal leaves and that this process is light quality dependen...
Intraspecific grafting with selected scions and rootstocks was used to study drought tolerance in the recalcitrant Mediterranean conifer P. pinaster. Conifers store different terpene types needles, stems roots, which can be modified by drought, but most studies have focused on a single organ over terpenes limits understanding of overall plant response. In this work, profile (160 components amon...
The xylem-limited bacterium Xylella fastidiosa (Xf) causes Pierce's disease (PD), an important disease of grapevine, Vitis vinifera L. Grapevine rootstocks were developed to provide increased resistance to root disease, but rootstock effects on cane and vine diseases remain unclear. Grapevines that consisted of Cabernet Sauvignon or Chardonnay grafted to 13 different rootstocks were inoculated ...
Grafting is an important, widely used plant propagation technique but its physiological effects are as yet insufficiently understood. Recent studies indicate that movement of proteins and small RNAs through the graft union might be involved. MicroRNAs are known to play a significant role in regulation of higher plants’ developmental and metabolic traits. Extending this logic, we hypothesize tha...
Local translocation of small RNAs between cells is proved. Long distance translocation between rootstock and scion is also well documented in the homo-grafting system, but the process in distant-grafting is widely unexplored where rootstock and scion belonging to different genera. Micro RNAs are a class of small, endogenous, noncoding, gene silencing RNAs that regulate target genes of a wide ra...
ABSTRACT The availability of water with low electrical conductivity for irrigation in the Northeastern semi-arid region is one limiting factors expansion irrigated agriculture. Thus, it necessary to use waters high conductivity, requiring search strategies reduce negative impacts salts on plants. In this context, objective study was evaluate morphophysiology and production guava cv. Paluma subj...
