Defining the Substrate Spectrum of the TIM22 Complex Identifies Pyruvate Carrier Subunits as Unconventional Cargos

Mitochondria carrier proteins, which possess six transmembrane spans (TM), are transported by the TIM22 complex. By using a quantitative proteomic approach, Gomkale and Cruz-Zaragoza et al. reveal subunits of the mitochondrial pyruvate carrier (MPC) that possess two or three TMs as unexpected substrates of the carrier pathway

Effect of Pulsed Concentrated Solar Radiation on Seeds and Plants

11-13Role of sunlight for plant growth through photosynthesis is well known. The systematic use of concentrated sunlight is being made in medicine, biology and chemistry since last three decades. To avoid the burning effect of concentrated sunlight, Pulsed Concentrated Solar Radiation (PCSR) was developed, in which seeds of biological objects are exposed intermittently. The PCSR increased the germination, plant growth, development and productivity in many crops with early maturity by 3 to 6 d. The treatment accelerates the metabolism, which leads to active growth of embryo. This treatment has been reported to increase the content of nucleic acids, sugars, vitamins, quality of produce and even acts as a promising mutagenic factor
