Incorporation of compound inflorescences and selection of high-yielding progenies in cowpea [PDF]

Pesquisa Agropecuária Brasileira, 2018
: The objective of this work was to obtain cowpea (Vigna unguiculata) progenies with compound inflorescences, short peduncles, early cycle, good plant architecture, and high-yielding potential. The initial genetic material consisted of 453 F2:3 progenies,

Transfer of the hop (Humulus lupulus L.) alpha-bitter acid content to progenies of F1 and I1 generations in selected parental components

Plant, Soil and Environment, 2003
In the period 1999-2001 the transfer of a-acid content from selected parents to their progenies was evaluated. Four female plants (English varieties Target and Yeoman, German variety Magnum and Czech variety Premiant) and four male plants from the gene ...

Number of progenies and repetitions for reciprocal full-sib recurrent selection programs in maize

Ciência e Agrotecnologia, 2021
For a reciprocal recurrent selection (RRS) program to succeed, it is essential to maintain genetic variability throughout the selection cycles and to obtain accurate estimates of genetic parameters, which in turn are directly related to the number of ...

Nutrient/TOR signaling controls adipose mitochondrial transcription factor A (TFAM) to regulate organismal growth in Drosophila

FEBS Letters, EarlyView.
Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...
