We recently demonstrated that cell elongation in plants is regulated by a triantagonistic bHLH system, in which three bHLH proteins, Activator of Cell Elongation 1 (ACE1), Arabidopsis ILI1 binding BHLH 1 (AtIBH1) and Paclobutrazol Resistance 1 (PRE1), competitively regulate the expression of genes for cell elongation. Here we show that ATBS1 Interacting Factor 2 (AIF2), AIF3 and AIF4 interact w...

Glucose and phytohormones such as abscisic acid (ABA), ethylene, and gibberellin (GA) coordinately regulate germination and seedling development. However, there is still inadequate evidence to link their molecular roles in affecting plant responses. Calcium acts as a second messenger in a diverse range of signal transduction pathways. As calcium sensors unique to plants, calcineurin B-like (CBL...

A method is described for the simultaneous determination of diclobutrazol, flusilazole, flutriafol, hexaconazole, paclobutrazol, and tetraconazole in apple and pear pulps used in baby food at a limit of 0.01 mg/kg. Apple and pear pulp samples are subjected to selective solid-phase microdispersion (SPMD) with SPE-ED Matrix-38 and acetone-cyclohexane, and the extracts are cleaned up on a Florisil...

• Seed dormancy controls germination and plays a crucial role in the life cycle of plants. Chromatin modifications are involved in the regulation of seed dormancy; however, little is known about the underlying mechanism. • KYP/SUVH4 is required for histone H3 lysine 9 dimethylation. Mutations in this gene cause increased seed dormancy. KYP/SUVH4-overexpressing Arabidopsis plants show decreased ...

Because of its importance in the human diet, potato growth and development have received considerable scientific attention, especially regulation tuber development. The trend production has been toward greater acreage warm climates using cultivars that were developed for cool climates. However, low land tropical regions are characterized by high temperatures limit successful cultivation. High p...

abstract several root measuring methods have been developed until now but there is no single method of root measurement applicable for all situations. this study was conducted to evaluate the effects of a single trinexapac-ethyl (te) and paclobutrazol application on kentucky bluegrass root growth under three irrigation treatments. evaluating of root length density (rld), root surface area (rs) ...
