An assemblage of charred plant remains collected from 26 sites in the Yiluo valley of North China as part of an archaeological survey spans the period from the sixth millennium to 1300 calibrated calendrical years (cal) B.C. The plant remains document a long sequence of crops, weeds, and other plants in the country. The results also demonstrate the effectiveness of sediment sampling as part of ...

The high-molecular water-soluble preparations from several species of two genera (Symphytum and Anchusa) of Boraginaceae family Symphytum asperum, S. caucasicum, S.officinale and Anchusa italica were isolated. According to IR, C and H NMR, APT, 1D NOE, 2D heteronuclear H/C HSQC and 2D DOSY experiments, the main chemical constituent of these preparations was found to be caffeic acid-derived poly...

C4 photosynthesis evolvedmore than 60 times independently in different plant lineages. Each time, multiple genes were recruited into C4 metabolism. The corresponding promoters acquired new regulatory features such as high expression, light induction, or cell typespecific expression in mesophyll or bundle sheath cells. We have previously shown that histone modifications contribute to the regulat...

It is increasingly evident that new environmentally sustainable agricultural practices will be necessary to support an estimated human population of 9 billion by 2050. Considering the predicted climate change-associated events such as flooding, drought, increased temperatures, and increased soil salinity, it is critical to broaden our study and use of cereals and small grains. Millets offer sig...

During a large survey of agelenid spiders from different private and museum collections, a closer examination of material from all over Italy (including type material and fresh material) previously identified as Histopona italica Brignoli 1977, disclosed two new species for science, both belonging to the italica group. Based on the results of the present work, we describe Histopona leonardoi sp...
