Molecular markers for drought in sugarcane plants
Two sugarcane cultivars differing in their tolerance to drought
stress, RB867515 (higher tolerance, HT) and RB855536 (lower
tolerance, LT), were grown in the greenhouse for three months.
Water was withheld for 2, 4, 6 or 8 days, and stress symptoms,
such as leaf rolling and senescence, appeared early on the second
day. By the sixth day, almost all of the stressed plants were severely
affected (Supporting Information, Figure S1 and Figure S2). Based
on these results, we decided to evaluate the plants that were
stressed at two and four days.
