Optimization of the composition of crop collections for ex situ conservation [PDF]
, 2009 Many crop genetic resources collections have been established without a clearly defined conservation goal or mandate, which has resulted in collections of considerable size, unbalanced composition and high levels of duplication.

Physiologia Plantarum, Volume 178, Issue 3, May/June 2026.ABSTRACT Pyrroloquinoline quinone (PQQ) is a redox cofactor derived from prokaryotes that participates in various biological processes involving dehydrogenase enzymes. Previous field trials identified a PQQ‐producing endophyte, Burkholderia seminalis 869T2, which enhances banana growth and reduces Fusarium wilt incidence from 24.5% to 3.4%.

Compound current conveyor (CCII + and CCII - )
Electronics Letters, 1997 A CMOS current conveyor configurable as CCII/sup +/ and/or CCII/sup -/ is proposed. The circuit has the advantages of providing two symmetrical outputs, presenting a low input resistance and giving a high output to input resistance ratio. An input resistance of 28 /spl Omega/ with a zero at 6 MHz in a 0.5 /spl mu/m implementation with a supply voltage ...
