In the first part of this talk, I will summarize recent developments in the study of the chiral-odd spin-dependent parton distributions h1(x,Q2) and hL(x,Q2) of the nucleon, in particular, (i) Next-to- leading order Q2 evolution of h1(x,Q2) and (ii) Leading order Q2 evolution of the twist-3 distribution hL(x,Q2) and the universal simplification of the Q2 evolution of all the twist-3 distributions in the large Nc limit. The second part of this talk will be devoted to a systematic analysis on the light-cone distribution amplitudes of vector mesons (ρ, ω, ϕ, K^* etc) relevant for exclusive processes producing these mesons. In particular, twist-3 distribution amplitudes are discussed in detail.
