Transgenic Lines

Remobilization of pre-anthesis NSCs (non-structural carbohydrates) is significant for effective grain filling in rice (Oryza sativa L.). However, abundant starch particles as an important component of NSCs are still present in the leaf sheath and stem at the late stage of grain filling. There are no studies on how bioengineering techniques can be used to improve the efficiency of NSC remobilization. In this study, RAmy1A was expressed under the senescence-specific promoter of SAG12, which was designed to degrade starch in the leaf sheath and stem during grain filling. RAmy1A mRNA successfully accumulated in the leaf, stem, and sheath of transgenic plants after anthesis. At the same time, the starch and total soluble sugar content in the leaf, stem, and leaf sheath were obviously decreased during the grain-filling period. The photosynthetic rate of transgenic lines was higher than that of the wild types by an average of 4.0 and 9.9%, at 5 and 10 days after flowering, respectively. In addition, the grain-filling rate of transgenic lines was faster than that of the wild types by an average of 26.09%. These results indicate an enhanced transport efficiency of NSCs from source tissues in transgenic rice. Transgenic rice also displayed accelerated leaf senescence, which was hypothesized to contribute to decreased grain weight.

Small Increments

Penicillin promoted elongation of rice (Oryza sativa L.) seedlings; the relative promotion of shoot elongation was stronger than that of root elongation. Nucleic acids and protein were maintained at much higher levels in seedlings treated with penicillin, the increment of these metabolites being more pronounced in the embryo than in the endosperm. α-Amylase, RNase, and ATPase of endosperm and indoleacetic acid (IAA) oxidase activities of the entire seedlings were enhanced in penicillin treatments. Penicillin caused small increments in respiration rates of seedlings. IAA-induced growth inhibition of intact seedlings could be reversed completely to a growth promotion by joint application of penicillin with IAA. The length of the second leaf sheath of a dwarf rice cultivar was increased by penicillin which further enhanced the gibberellin-induced response. The levels of gibberellinlike substances were increased by penicillin treatments, whereas the IAA level remained unchanged. In penicillin-treated seedlings, more IAA was transported from endosperm to embryo. The stimulating effect of penicillin on rice seedling elongation was partially reversed by abscisic acid and the interaction appeared to be of a noncompetitive nature.
