Puroindoline (Pina and Pinb) genes control grain texture or hardness in wheat. Wild-type/soft alleles lead to softer grain while a mutation in one or both of these genes results in a hard grain. Variation in hardness in genotypes with identical Pin alleles (wild-type or mutant) is known but the molecular basis of this is not known. We now report the identification of wheat genotypes with hard g...

A copper-catalyzed regioselective and stereospecific aminoboration of vinylsilanes with bis(pinacolato)diboron (pinB-Bpin) and hydroxylamines has been developed. In the presence of a CuCl/MeO-dppbz catalyst, the boryl group and amino group are incorporated at the β position and α position, respectively, and the corresponding β-boryl-α-aminosilanes are obtained with good diastereoselectivity. Th...

The puroindoline proteins (PINA and PINB) of wheat display lipid-binding properties which affect the grain texture, a critical parameter for wheat quality. Interestingly, the same proteins also display antibacterial and antifungal properties, attributed mainly to their Tryptophan-rich domain (TRD). Synthetic peptides based on this domain also display selectivity towards bacterial and fungal cel...

Wild einkorn (Triticum monococcum L. ssp. aegilopoides (Link) Thell.) is a diploid wheat species from the Near East that has been classified as an ancestor of first cultivated (einkorn; T. monococcum). Its genome (Am), although it not donor A in polyploid wheat, shows high similarity to Au genome. An important characteristic for improvement grain quality, which associated with three components ...

The use of the N-phosphinoamidinato NHC-diborene catalyst 2 for hydroboration is described. N-phosphinoamidine tBu2PN(H)C(Ph)?N(2,6-iPr2C6H3) was reacted with nBuLi in Et2O to afford lithium derivative, which then treated B2Br4(SMe2)2 toluene form N-phosphinoamidinate-bridged diborane 1. It N-heterocyclic carbene IMe (:C{N(CH3)C(CH3)}2) and excess potassium graphite at room temperature give com...
