WEBVTT 1 00:00:00.560 --> 00:00:03.143 (upbeat music) 2 00:00:09.797 --> 00:00:14.797 line:15% When we talk about love, hate, smile, or stress, 3 00:00:15.100 --> 00:00:17.710 line:15% we usually think about humans or animals, 4 00:00:17.710 --> 00:00:20.380 line:15% but science has proved that plants also have 5 00:00:20.380 --> 00:00:22.910 all kinds of emotions and reactions 6 00:00:22.910 --> 00:00:25.760 and like humans, they don't like any kind of stress, 7 00:00:25.760 --> 00:00:28.792 but unfortunately, they also face a lot of stresses, 8 00:00:28.792 --> 00:00:32.640 like water stress, drought, salinity, etc. 9 00:00:32.640 --> 00:00:34.070 But does that mean that they cannot 10 00:00:34.070 --> 00:00:36.510 be grown under stressful conditions? 11 00:00:36.510 --> 00:00:40.130 The answer is no, they can be, but how? 12 00:00:40.130 --> 00:00:42.250 Well, lets put this to an example. 13 00:00:42.250 --> 00:00:44.970 Suppose your professor got a challenging research project 14 00:00:44.970 --> 00:00:47.620 and he needs a competent and productive student. 15 00:00:47.620 --> 00:00:49.250 What do you think he should do? 16 00:00:49.250 --> 00:00:52.170 Well, he'll definitely make a proper strategy first, 17 00:00:52.170 --> 00:00:54.250 select a diverse panel of candidates, 18 00:00:54.250 --> 00:00:56.997 check their resumes, and may even take an exam 19 00:00:56.997 --> 00:00:59.530 to further explore their potential. 20 00:00:59.530 --> 00:01:01.470 Now, in plant sciences, we call this 21 00:01:01.470 --> 00:01:03.890 whole process a screening technique. 22 00:01:03.890 --> 00:01:06.640 My research aims to screen rice cultures 23 00:01:06.640 --> 00:01:08.820 based on morpho-physiological traits 24 00:01:08.820 --> 00:01:10.160 and identify the ones having 25 00:01:10.160 --> 00:01:12.580 high potential for stress tolerance. 26 00:01:12.580 --> 00:01:14.160 And then further confirm their potential 27 00:01:14.160 --> 00:01:17.870 at molecular level using genomorph association study 28 00:01:17.870 --> 00:01:19.950 or GWAS, which examines the whole 29 00:01:19.950 --> 00:01:22.410 genome set of cultures to find places 30 00:01:22.410 --> 00:01:25.830 in the genomes called snips, cutials, or genes, 31 00:01:25.830 --> 00:01:28.950 responsible for producing stress tolerance. 32 00:01:28.950 --> 00:01:30.990 As a result, we can also determine 33 00:01:30.990 --> 00:01:32.790 which of the morpho-physiological traits 34 00:01:32.790 --> 00:01:35.820 are more important in screening for stress tolerance. 35 00:01:35.820 --> 00:01:38.160 As shown here in Figure One, where the traits 36 00:01:38.160 --> 00:01:40.780 that deviate more from the center are more likely 37 00:01:40.780 --> 00:01:43.220 to have a higher number of significant snips 38 00:01:43.220 --> 00:01:46.400 and thus possess high potential for stress tolerance. 39 00:01:46.400 --> 00:01:48.230 GWAS can further tell us the exact number 40 00:01:48.230 --> 00:01:50.750 of snips and genes responsible for policing 41 00:01:50.750 --> 00:01:53.500 stress tolerance in any particular trait. 42 00:01:53.500 --> 00:01:55.020 For example, like root length, 43 00:01:55.020 --> 00:01:57.040 as shown here in Figure Two. 44 00:01:57.040 --> 00:01:59.930 And then finally, the morpho-physiological screening 45 00:01:59.930 --> 00:02:01.570 along with the genetic assessment 46 00:02:01.570 --> 00:02:03.790 could be used to gather to classify 47 00:02:03.790 --> 00:02:06.160 all the cultures into different categories. 48 00:02:06.160 --> 00:02:08.240 As shown here in Figure Three, 49 00:02:08.240 --> 00:02:10.580 which shows the exact number of drought, 50 00:02:10.580 --> 00:02:13.320 salinity, and neat unstressed ricino types 51 00:02:13.320 --> 00:02:15.510 that are found in my studies. 52 00:02:15.510 --> 00:02:19.270 In conclusion, the integrated morpho-physiological screening 53 00:02:19.270 --> 00:02:20.810 along with the genetic assessment 54 00:02:20.810 --> 00:02:23.490 could be used to gather to identify 55 00:02:23.490 --> 00:02:26.640 the stress-friendly traits, the stress tolerance rates, 56 00:02:26.640 --> 00:02:30.520 snips, cutials, and A1 genes that are responsible 57 00:02:30.520 --> 00:02:33.238 for producing stress tolerance in any crop. 58 00:02:33.238 --> 00:02:35.180 My research also has a take-home 59 00:02:35.180 --> 00:02:37.200 social message for all of you, 60 00:02:37.200 --> 00:02:39.580 that, as humans, you also need to identify 61 00:02:39.580 --> 00:02:42.820 all the stresses in your life and get rid of them 62 00:02:42.820 --> 00:02:44.600 before they affect your performance. 63 00:02:44.600 --> 00:02:47.497 Thank you.
