Tomatoes for the
astronauts
Space missions are a bit like a marathon with checkpoints – only once the first model of a satellite has been successfully
tested will construction commence on the actual flight model. The Eu:CROPIS satellite developed by the German
Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), which will operate two greenhouses under
Martian and lunar conditions, has now reached this milestone – construction of the flight model can now begin. The
finish line is already in sight: launched by Space-X, the satellite and its scientific payload took off for outer space on
board the Falcon 9 in the second half of 2017. “We constructed the model here at DLR Bremen, and conducted
rigorous flight tests,” explained engineer Hartmut Müller, Project Manager for satellite construction at the DLR Institute
of Space Systems.

During its mission, the Eu:CROPIS
satellite is designed to rotate at an altitude
of 600 kilometres, initially replicating lunar
gravity for a period of six months before
simulating Martian gravity for the next six
months.

How to treat against

seemingly out of the blue.
   The females lay eggs singly, usually on younger leaves or
flower buds. The young larvae start by eating these, then often
move on to the fruit and stems. They burrow into the fruit and
can often be seen half in and half out of the holes they create;
the damage makes the fruit unmarketable. Many worms remain
within the larger fruit, where they are safe from pesticides. They
also bore down the main stem of the plant. The eggs are fairly
easy to spot on the young shoots, but the best way to determine
the presence of egg-laying moths is to set pheromone traps at
strategic spots. If these attract male moths, the pest is active
and measures should be taken to control the young caterpillars.

Sticky, prickly and
heavily armed
Armed with long thorns and sticky stems, newly described plant
Solanum kollastrum might look like a villain by plant standards,
but a closer look on this curious new species will reveal its
star-like nature   in   the    context     of  its   ecosystem.
Recently described in open access journal PhytoKeys, this newly
discovered tomato relative boasts stems densely armed with prickles
of up to 17 mm long and to 2.3 mm wide at the base. In fact, the new
species is baptised after yet another showy defence mechanism. The
name kollastrum comes from the Greek words for glue and star, referring
to the peculiar sticky hairs that end in a star-like formation. While all this
heavy armour might at first fool you that this new species lives in isolation, a
closer look has revealed that, contrary to the expectations, S. kollastrum starts
as the good guy in its ecosystem. In its own right, Solanum is an extremely
diverse plant genus to which important crops such as potatoes, tomatoes and
eggplants belong. Endemic to eastern Brazil, the known records of the armed
new species are mostly concentrated along the Mucuri River watershed, where it
inhabits edge of small forest fragments. In fact, the species is especially seen in areas
at the base or on the peculiar and gigantic geological formations known as inselbergs or
‘sugar loaves’.Some populations were also found in disturbed sites near these rock outcrops,
such as borders of unpaved roads and pastures. “The discovery of S. kollastrum, a robust and
conspicuous plant growing at the roadsides in regions close to large urban centres, highlights how
insufficiently known the Brazilian flora is,” explain authors from the Universidade Federal de Minas
Gerais and Universidade Federal do Oeste do Pará, Brazil.“This highlights how urgent the need is to
describe, study and conserve the country’s plant diversity. Thus, we hope that this discovery encourages the
study on the most diverse aspects of this species’ biology.”

RESEARCH
Genetics of Stress
While trying to understand genetics of stress to make tomatoes and other crops more productive,
Indian researchers have identified a gene that helps the tomato plant tackle pathogens as well as heat stress.

well as uninfected plants showed a significant upregulation of one DEAD-box RNA helicase gene which prompted us to go for its
characterisation,” says Dr Manoj Prasad, who led the research team. “We find that SlDEAD35 gene plays crucial role against virus as
well as heat stress, which might provide the framework for improved yield and tolerance against combined stress in tomato,” he adds.
   Developing systems for tolerance or resistance against combined stresses is important for future crop production. “We have found
a candidate gene which might provide the framework to understand the science behind plants’ response against combined stresses.
We can introduce the gene through molecular breeding to develop varieties for the combined stress tolerance in tomato,” says the
lead author, Saurabh Pandey.
